Strategic Gold and Quartz deposits in Caturama, Bahia. BR Mining presents a promising investment opportunity in Brazil’s mineral-rich interior, with high exploration potential. Gold Cansanção - BA The area of mining process no. 870.860/2021 occupies 49.66ha and is located in the municipality of Caturama, Bahia, Brazil. HIGHLIGHTS GOLD RESERVES The project shows high potential for increasing reserves, with three main targets defined containing significant gold anomalies identified in rock, soil, and drainages. The presence of primary gold (in rock) and secondary gold (in soil and alluvium) indicates the possibility of upgrading the current occurrences to deposit status in the next research phases. GEOLOGICAL FORMATION The area is located within the Rio Itapicuru Greenstone Belt, a metallogenic province recognized for hosting mesothermal gold deposits. Locally, the geology consists of mafic metavolcanics and volcanoclastic metasediments, cut by mineralized shear zones containing quartz veins, sulfides, and iron oxides. These structural and lithological characteristics enhance the potential for high-grade gold mineralization. LOCATION Access to the area is facilitated by paved highways (BR-324 and BA-120) up to Santaluz, followed by well-maintained municipal roads leading to the polygon. The proximity to regional urban centers and the support of local landowners reduce logistical barriers and favor the advancement of exploration activities and, in the future, mining operations. PROJECT VIABILITY The favorable geological setting, the positive results from preliminary surveys, and the confirmation of multiple mineralized zones support the project's economic viability. The plan includes new drilling phases and metallurgical characterization to quantify reserves and define the economic exploitation plan, reinforcing the potential for establishing a profitable mining operation in the region. Tune in to our exclusive podcast showcasing the Gold & Quartz deposit in Caturama, Bahia. Deep Dive BRM Podcast 00:00 / 15:29 GENERAL PROCESS DATA The polygon in question is located in the municipality of Cansanção, Bahia. This ANM process was granted to the titleholder after an auction phase for available areas, which in this case provided the opportunity to acquire the area under the original process No. 871.825/2010. LOCATION AND LOGISTICS The polygon of the mining process in focus is situated within the municipal boundaries of Cansanção, State of Bahia (Figure 01). There are different routes to access the area from the capital, Salvador; however, due to better road conditions and a shorter total distance, the route through the city of Santaluz-BA will be considered here. This route includes the paved highways BR-324 and BA-120, followed by municipal roads from Santaluz and Cansanção leading to the polygon. Fig 1. Municipal roads between Santaluz and the ANM process area in focus SURFACE LANDOWNERS There are only three landowners within the polygon area of the ANM process. The possible spatial distribution, based on updated CAR (Rural Environmental Registry) data, can be observed in Figure 02. It is worth noting the interest of the landowners in the development of mineral exploration and the implementation of an extraction project, which facilitated the research. Additionally, the properties of Mr. José das Virgens and Mr. “Galego” are considered the most strategically important, as they are geologically the most promising and encompass the main targets. Fig 2. Map of landowners of ANM Process No. 870.860/2021 according to field data. MUNICIPAL ASPECTS The municipality of Cansanção covers a territorial area of 1,351.891 km² (IBGE 2020), has one of the strongest commercial sectors in the sisal macro-region, and serves as one of the main highway junctions in the north-central portion of Bahia. The estimated population in 2022 was 37,439 inhabitants. Although there are no large-scale mining companies in operation, much of the eastern sector of the municipality shows promising mineral potential for gold and other substances. This is evidenced by the existence of dozens of artisanal mining sites in the region. In the rest of the municipality, land use is dominated by sisal cultivation and general livestock farming. LOCAL ASPECTS The area of ANM Process No. 870.860/2021 is located near the “Nova Vida” settlement district, approximately 7.5 km away. The main economic activity there is gold production through dozens of artisanal mining operations scattered in the surrounding area. Sisal cultivation and subsistence livestock farming occur as secondary activities, but are also present. The district of Nova Vida has treated water supply and electricity for local residents. Rural properties mostly have only electricity, with water supply relying on private sources. Local infrastructure is precarious, with no health clinics, schools, or restaurants, which must be sought in more distant districts. Specifically within the studied polygon, only livestock farming is carried out by the three landowners. There are gold mining operations nearby, but they are located outside the polygon boundaries. GENERAL PHYSIOGRAPHIC ASPECTS The climate in the mining process area under focus, as well as in other regions of the municipality of Cansanção, is similar. It is classified as tropical sub-humid to dry (according to Köppen-Geiger, 1901), with average temperatures above 22 °C and higher rainfall between November and April, coinciding mostly with summer (Figure 03). Fig. 3. Monthly rainfall and temperatures for the municipality of Araci, Bahia. Figure 03 shows that, despite wetter summers and colder, drier winters, the region’s average annual rainfall is low, totaling less than 750 mm/year. The relief of the area results from pediplanation processes over volcanic terrains of the Rio Itapicuru Greenstone Belt, corresponding to a flattened erosive surface marked by low hills and shallow valleys, cut by a drainage system that integrates into the Rio Itapicuru basin (located about 6 km south of the area). The soils occurring in the proximity of the studied polygon are strongly associated with the local basaltic volcanic unit, where a highly clayey, dark red material predominates, popularly known as “massapê,” technically classified as red latosol (Brazilian Soil Classification System, EMBRAPA, 1999). The macro-region, as well as the polygon itself, is characterized by dense arboreal caatinga interspersed with pasture areas or sisal plantations. Within the mining process polygon in question, land use is approximately 39% native vegetation and 61% cattle pasture. GEOTECTONIC EVOLUTION AND REGIONAL GEOLOGY The regional geology influencing the ANM process area 870.860/2021 is well known and has been characterized by various authors. In summary, it consists of the compartmentalization of the units that make up the crystalline basement and the GBRI (Greenstone Belt of the Rio Itapicuru). The GBRI is a set of low-grade metamorphosed lithostratigraphic units described below. These metavolcanosedimentary rocks form a zone of preserved ancient rocks with high metallogenetic fertility, in this case geologically overlying the gneiss-migmatitic rocks of the Santaluz Complex, within the Serrinha Block of the São Francisco Craton (SFC). SÃO FRANCISCO CRATON (SFC) The SFC developed in a geotectonic context of Archean block accretion during the Paleoproterozoic. This evolution, described primarily by several authors in works such as BARBOSA (1990) and BARBOSA & SABATÉ (2003), highlights the importance and complexity of the geological events associated with this structuring. The SFC was also considered by ALMEIDA (1971) as a pre-Brasiliano continental basement core, consolidated about 2.08 Ga after the continental convergence of four Archean crustal segments (Figure 05). BARBOSA & SABATÉ (2003) defined the aforementioned blocks as: Jequié Block, Itabuna-Salvador-Curaçá Belt, Gavião Block, and Serrinha Block — the latter being of greatest interest for understanding the regional geology of the ANM process area in focus. Fig. 4. Geotectonic map of the collage of blocks that consolidated the formation of the CSF, highlighting the region where the mining process under focus is located. Source: Modified from Barbosa and Sabaté, 2012. - SERRINHA BLOCK The Serrinha Block is one of the tectonic compartments comprising the SFC. Various authors, such as Cruz Filho et al. (2005), describe this block as an ellipsoidal mega-structure covering an area of 21,000 km². It is part of the orogenic domain of eastern Bahia, generated during the SFC collisional event that occurred between 2.1 and 2.0 Ga. Fig. 5. Regional geological map of the Serrinha Block highlighting the area where the mining process in focus is located. Source: Modified from Barbosa and Sabaté, 2012. - GREENSTONE BELT OF RIO ITAPICURU (GBRI) The GBRI comprises the main lithostructural units influencing the mineral studies and research carried out in the ANM process area under focus. This set of metavolcanosedimentary rocks is elongated in a N-S direction, covering an area larger than 7,500 km² across more than 10 municipalities in Bahia. It is interpreted as a remnant of an oceanic arc that collided with an Archean continent approximately 2,130 to 2,105 Ma ago (Oliveira et al., 2010). Due to the great metallogenetic potential within the GBRI units, numerous research efforts have been undertaken for scientific and exploratory purposes, resulting in large-scale mining of gold in Santaluz and Barrocas and diamonds in Nordestina, for example. This importance is reflected in a rich bibliography on the lithostratigraphic compartmentalization of the GBRI rocks, shown in Figure 6 and summarized as follows: Mafic Metavolcanic Unit (UVM): Occurs throughout the GBRI and consists of massive basaltic flows, with U-Pb age of 2145 Ma (Oliveira et al., 2010), and pillow lavas intercalated with pelitic and chemical sedimentary rocks; Felsic Metavolcanic Unit (UVF): Andesitic to dacitic flows with U-Pb age of 2081 Ma (Oliveira et al., 2010), interlayered with pelites, rhythmites, sandstones, arkosic sandstones, and conglomerates. Pyroclastic rocks such as breccias, agglomerates, ignimbrites, and tuffs are also present; Volcanoclastic Metasedimentary Unit (USV): Composed of turbiditic sequences intercalated with chemical sediments and epiclastic rocks. Around 2110 Ma, intense igneous activity occurred with emplacement of high-K to ultrapotassic plutons at the greenstone–basement transition, generally ellipsoidal and elongated N-S. Notable intrusions include Morro do Afonso syenite, Itareru tonalite, and Fazenda Gavião granodiorite with ages between 2105 and 2110 Ma (Costa et al., 2011). Fig. 6. Regional geological map of the Granite-Greenstone terrain of the GBRI highlighting the area where the mining process under focus is located. Source: Modified from Barbosa and Sabaté, 2012. This entire volcanosedimentary sequence was metamorphosed under greenschist facies during basin closure. At this stage, syn-tectonic intrusive bodies emerged, causing higher-grade metamorphism at their margins, with amphibolite facies (Silva, 1992). Structurally, the GBRI is complexly organized. Differences in rheology among the various rock types, combined with multiple phases of compressive events in the basin, generated a succession of synclines and anticlines bounded by regional shear zones exhibiting sinistral kinematics, oriented N-S in the central-northern portion and E-W in the southern portion (Weber Belt). Two main deformational events affected the sequence (Alves da Silva 1994; Chauvet et al., 1997): D1 : Southeast-verging thrusts preserved in the southern GBRI; D2 : Resulting from the progression of D1 into a transcurrent tectonics, generating major sinistral N-S shear zones, postdating the emplacement of syn-tectonic granito-gneissic domes (Ruggiero & Oliveira, 2010). As recognized in other Granite-Greenstone terrains, gold mineralizations in the GBRI are structurally controlled in mesothermal deposit types. Transcurrent shear zones act as primary conduits for hydrothermal fluids, mineralizing altered host rocks and associated quartz veins. This structural control guides exploration activities following mapping and structural identification. IDENTIFIED MINERAL POTENTIAL The mineral exploration conducted within the polygon of ANM process 870.860/2021 comprised a total of seven distinct activities carried out during the term of the exploration permit, subdivided according to the central technical development objective of the project: Basic research stages , such as literature review, geoprocessing for the preparation of thematic maps, and local/regional geological reconnaissance, aimed at identifying the mineral potential of the area, enabling a new overall plan and defining the feasibility of further investments. Advancing to more specific exploratory research stages , the central objective shifted to enabling promising targets for a gold mining project. These activities included 1:8,000-scale geological mapping, rock sampling, soil and stream sediment sampling, trench excavation, and data correlation for future exploration planning. SURVEY OF PRE-EXISTING DATA This stage aimed at a deeper understanding of the regional and local geology, as well as identifying relevant available information that could optimize the progress of the work. A literature review was conducted covering various studies in the target region, ranging from scientific articles and academic papers to open publications from private companies that carried out different research and studies in the Rio Itapicuru Greenstone Belt. Open files from the Companhia Baiana de Pesquisa Mineral (CBPM) and CPRM (Geological Survey of Brazil) provided regional geological maps and important information from airborne geophysical surveys, mining history, geochronology, and structural geology. Examples include data from the Programa Levantamentos Geológicos Básicos do Brasil – Folha SC-24-Y-D Serrinha (CPRM) and the Projeto Mapa Metalogenético do Estado da Bahia (CBPM). Scientific articles and especially undergraduate theses (TCCs) focusing on gold mineralization at the “Maria Preta – C1” mine, the “Alvo M4” target, and the “Mary Trend”—all approximately 8 km from the study area—clarified the lithostratigraphic subdivision of the central part of the GBRI and the relationship between shear structures, arsenic-bearing sulfide anomalies, and gold. DEVELOPMENT OF THEMATIC MAPS Several maps of the study area were created to infer geological and structural information prior to field activities, identify the best access routes, and optimize research work. Through geoprocessing, maps of traverses, homologous zones, drainage, preliminary geological-structural layout, prospective program, and airborne regional magnetometry were produced. In addition to pre-existing shapefile archives, “ICONOS” and “ALOS” satellite images processed in image-editing software, digital terrain models from NASA and INPE (both with 30 m resolution), 15 m resolution SRTM with four-quadrant illumination, and Google Earth images (2005 to 2020)—which offered excellent quality for the region—were used. All spatial data were processed and georeferenced (datum WGS 1984, zone 24S) using ArcGIS 10.8. Fig. 7. Examples of some thematic maps from previous interpretations, which allowed for better planning of subsequent fieldwork stages. FIELD RECONNAISSANCE As previously described, the target polygon is located in a geological context extremely favorable for the presence of gold occurrences. Therefore, in addition to reviewing the regional geology and general maps, a regional field reconnaissance was necessary to understand the mineral controls of the dozens of nearby artisanal mines, as well as to verify whether the field data were consistent with observations from the literature. In total, 19 points were visited during the regional reconnaissance, distributed between outcrops and artisanal mines. Strategic information was also gathered, such as identification of key landowners, land use in the area, vegetation type, and main drainage networks. Fig. 8. Map of gold occurrences and artisanal mines within the area of influence of the ANM process in focus. Photo 2. Both photos illustrate some of the artisanal gold mines visited during the regional field reconnaissance. Note the thickness of the clayey soil above the fresh rock, which hinders the identification of mineralized layers without excavation. DEFINITION OF PROMISING TARGETS 1:8,000 GEOLOGICAL-STRUCTURAL MAPPING The purpose of the mapping was to identify the main lithotypes present and their surface extent, as well as the primary structural patterns and their influence on the context of gold occurrences. A total of 117 points were cataloged, divided between “control” and “main” points. During this stage, 46 rock samples (CHIP samples) were also collected, which will be described in the following sections. In Figure 9, which presents the developed geological map, it is evident that there is no great complexity in rock distribution within the area—something explained by the small size of the polygon. The geological units represented are described below. Fig. 9. Geological-structural map of the ANM process area in focus. Source: Arcangeo. LOCAL GEOLOGY As a result of the mapping, two main geological units were identified in the area: Mafic Volcanic Unit (MVU) – Metabasalts associated with metacherts Covers approximately 39 ha of the mapped area, located throughout the central and western portions of the polygon, following the general N040° trend. It has structural contact with the neighboring metasedimentary unit to the east and undefined contacts with associated chert cores. This unit is composed of metabasalts, here observed as light to dark green rocks with aphanitic texture and predominantly mafic composition. Rare millimetric amygdales with plagioclase occur. The rocks are foliated and sometimes fractured, with quartz veinlets aligned to foliation planes. Strong oxidation is frequent along fracture planes (mainly iron and manganese oxides). Sulfides such as pyrite can be seen disseminated in the rock matrix, but are more abundant near shear zones. Photo 3. The photos illustrate the main type of volcanic rock observed in the unit. In the last image on the right, note the presence of metallic oxidation in fractures—a common feature in these rocks. Alongside the basalts occur cores of recrystallized siliceous rocks, defined as ferruginous cherts, aligned to the same NE-SW structural trend. Cherts are composed mainly of microcrystalline quartz; in the delimited bands within the area, they show predominantly gray to black coloration with iron oxides. Well-formed quartz crystals in centimeter-scale open spaces are also a distinctive feature. Photo 4. Both photos show outcrops and macroscopic features of the ferruginous chert in the MVU. Volcanoclastic Metasedimentary Unit – Varied metasediments Covers approximately 10 ha of the mapped area, occurring from north to south along the eastern side of the polygon with the same general N040° trend. This unit includes sedimentary rocks rich in siliceous sediments, with minor occurrences of associated andesitic rocks. However, the most prevalent lithologies are various schists, ranging from sericite-quartz schist to muscovite-sericite-quartz schist. Numerous quartz pebbles (white, milky, smoky) occur throughout the unit, interpreted as being linked to the whole unit but more abundant near structural features such as faults and shear zones. Layers of quartzites, metarenites, metaandesites, phyllites, and cherts are also present. This varied interlayering of lithotypes, combined with the structural development that formed the penetrative foliation in the schists, may have enhanced the geological potential of this unit. The following sections will provide more details on the structural compartmentalization and mineralization controls. Photo 5. From left to right: Large phyllite cobble, quartzite cobble, and chlorite–quartz–schist cobble, the latter being the predominant rock in the unit in focus. STRUCTURAL GEOLOGY Despite the small size of the mapped area, some considerations regarding structural geology are extremely relevant, since in this geological environment, gold mineralization is mainly controlled by structural features. Shear Zones (SZs): They occur following the general trend of the area, accompanying the foliation between N025–045° directions. During geological mapping, it was not possible to observe the contact between units in outcrop. However, it was possible to infer their presence through the correlation of outcrops and association with topographic structures, with shear zones identified in some of these contacts (see Figure 9). This was determined based on typical features of SZs in the region, such as a large quantity of quartz veins (QVZs) plus quartz cobbles, highly foliated rocks, and sometimes the presence of hydrothermal alteration halos. Photo 6. From left to right: Sample of altered and deformed basalt in a shear zone; example of smoky quartz with iron oxide; and milky quartz vein with pyrite. All samples were interpreted as being associated with geological structures with high potential for gold mineralization. Foliation : Only a few reliable foliation (Sn) measurements were obtained for the units, mainly from points located within drainage areas, such as P44 and P19, which allowed for observation of rock strike and dip. Trenches also provided such data. In general, foliation in the area is weakly marked in basalts, whereas in metasediments it is more penetrative and easily visible. Near what was classified as SZs, cobbles are also highly foliated. The identified trend predominantly ranges from N020°–045°, with dips between 65–85° toward the NW. Faults and other structures: Structural lineaments in relief, faults, and fractures were inferred or observed through indirect data such as digital terrain models, satellite imagery, outcrops, and trenches. The individualization of each structure group was not precise; for example, faults and fractures were differentiated only by the degree of rock/cobble fragmentation in the area. Brittle structures do not appear to have major relevance for the structural control of gold mineralization or for the distribution of the geological units mapped within the area of focus. ROCK SAMPLING (CHIP SAMPLE) Rock samples were collected during the geological mapping. They were described and cataloged to feed the project’s database, providing important information on which lithotypes are most promising for the presence of primary gold. A total of 46 samples were collected, of which only 20 were selected after macroscopic description and analyzed using the Fire Assay analytical method at the “Brastecno” laboratory in Belo Horizonte, MG. Table 1 below shows the results obtained, and Figure 10 shows their location on the map. The analysis certificates are included in the annexes. Table 1. General data of rock samples selected and analyzed during the surveys. Fig 10. Map showing location of samples/results of gold grades in rock. Source: Arcangeo. The anomaly data identified led to important geological interpretations and assisted in decision-making for exploratory planning, such as soil sampling and trench excavation. SOIL SAMPLING Identifying gold anomalies in soil is one way to focus research on more promising targets, especially when combined with other information (e.g., mapping and rock sampling). In this context, 58 samples were collected following a plan based on the results of previous stages. The methodology used was soil collection to a maximum depth of 20 cm where possible, using a simple manual digger. Good sampling practices were always followed — for example, cleaning tools after each collection to avoid cross-contamination between samples. Photo 7. Photos show soil sampling with 20 m spacing. Photo 8. From left to right: process of panning heavy concentrates with the help of a local miner; example of final concentrate from sample SS-4-A; and counting gold specks in an American pan, also for sample SS-4-A. Each sampling point had its location and altitude recorded. Samples were described, weighed, and panned to concentrate heavy minerals and count gold specks. Table 2 shows the results of the soil sampling, and Figure 11 shows the location of each point. A correlation between rock anomalies and soil anomalies was observed, further supporting target delimitation for more detailed exploration. Table 2. General data of soil samples panned for gold speck counting. Fig 11. Map of soil sampling locations. Source: Arcangeo . DRAINAGE SAMPLING Drainage studies in large areas are fundamental and strategic for defining high-potential zones in gold exploration projects. However, despite their relevance to the ANM process in focus, drainage sampling in the area yielded little data volume. This can be explained by: The area’s drainage network is small, all associated with a single sediment catchment basin, which does not allow clear differentiation of distinct gold-bearing potential zones; All assessed drainages showed favorable results for the presence of alluvial gold — meaning the entire polygon is theoretically under the influence of a mineralized zone. Fig 12. Map showing location of drainage panning concentrate samples. Source: Arcangeo. Fig. 12. Location map of pan concentrate sampling in drainages of the area. Source: Arcangeo. The methodology used was simple: using manual tools such as diggers, shovels, and pickaxes, gravel samples were collected at depths ranging from 25–60 cm, covering both deeper gravel and shallow, more recent sediments. These samples were cataloged and weighed, then panned to count gold specks, similarly to the soil sampling process. Photo 9. From left to right: example of drainage within the evaluated area; illustration of sample CB-11 collection; and result of gold speck count for the same sample, with extremely favorable results. Reviewing Figure 12 shows that the area has indications of gold throughout its extent, since the drainage network cuts across the predominant NE–SW structural trend, and positive anomalies are found throughout the catchment basin. TRENCHING After identifying some soil and rock anomalies and defining the geological structures influencing the area, two trenches were excavated over the metasedimentary geological unit. The trenches aimed to expose the rocks beneath the thick clayey soil covering the area, as well as to allow the collection of structural, geological, and sampling data. Trenches TR-1 and TR-2 were dug near positive anomaly zones from rock samples AM-REM2 and AM1-STLZ-C. A small backhoe was used, with maximum depths reaching 2.5 m and lengths of about 40 m each. All were logged in profile, and in TR-1, where rocks showed favorable characteristics, a channel sample was collected. Fig 13. Map showing trench locations in the eastern sector of the area. Source: Arcangeo. Photo 10. From left to right: logging of material removed from TR-1; and collection of structural data from altered metasediments in TR-2. Photo 11. Channel sample taken from TR-2, with no relevant gold content identified. IMPORTANT: The areas of greatest interest to the northwest and southwest of the polygon did not have trenches excavated, despite being planned, due to communication difficulties with the landowner at the time of the work. However, these will be excavated in the next research phases of the project. CONCLUSIONS As explained throughout this report, several mineral exploration activities were carried out within the polygon of ANM Process No. 870.860/2021, resulting in the delineation of targets for further work in the search for an economic gold ore deposit. Throughout the course of the work, investments were made in technical activities, reports, laboratory analyses, and various expenses (such as travel, vehicles, local labor, and food), among others, leading to the definition of three high-potential targets for intensified exploration. Fig. 14. Map of the new targets defined according to the data from the executed surveys. Source: Arcangeo. Regarding the gold ore, the area shows strong potential to elevate the various occurrences to the status of a deposit and later to that of a mine, a fact supported by several observations, such as: The regional and local geological context of the area is extremely favorable to gold mineralization, whether primary or secondary gold, with several artisanal mining sites just a few meters from the polygon confirming this assertion; The local geology of the polygon presents transitions between mafic metavolcanic and metasedimentary units, in addition to shear zone geological structures with promising mineral assemblages (sulfides, quartz veins/stringers, iron oxides, etc.); The results obtained in the exploration stages proved the existence of highly relevant gold anomalies in soil, drainages, and rocks, which made it possible to define targets that should be further investigated in new exploration phases. All the content addressed in this report leads to the conclusion that the polygon of ANM Project 870.860/2021 has great mineral potential for gold ore, as well as strategic characteristics suitable for developing an extraction project, making it justifiable to continue exploration in the area. NEW RESEARCH STAGES The main objective of continuing mineral exploration in the area is to intensify data collection within the three defined targets. The aim is to determine the economic feasibility of producing the possible existing reserve by obtaining information on the volume, geometry, and spatial distribution of mineralized bodies, average gold grade and contaminants, beneficiation route, and preparation of an Economic Exploitation Plan (PAE). Phase 1 – All Targets NEW SAMPLING : Additional rock tests will be carried out along with chemical-mineral characterization for the mineralized lithotypes, given that primary gold in the area may or may not be related to hydrothermal alteration “halos,” influencing mineral association and average grade. These activities will provide important details for defining the chemical quality/purity of the gold ore and its beneficiation characteristics. SOIL GEOCHEMISTRY: New soil sampling lines will be carried out, this time focused on the targets and with geochemistry associated with concentrates, thereby increasing the reliability of anomalous data for later trenching planning. GROUND GEOPHYSICS: Geophysical surveys will be important for deeper investigations. The use of IP (Induced Polarization) is expected in cases of anomalous gold-bearing sulfide halos, and electrical resistivity in cases of detecting resistive contrasts between gold-hosting structures and their host rocks. Phase 2 – Target "A" NEW TRENCHES AND PITS: New trenches and/or pits will be excavated to increase surface data density and better delineate possible mineralized layers. The results, together with geophysical interpretations, will provide the basis for planning the rotary drilling grid. Phase 3 – Targets "B" & "C" NEW TRENCHES AND PITS: Same approach as above, but applied to targets B and C. Phase 4 – All Targets DIAMOND CORE DRILLING: Core recovery will be fundamental to confirm grades, volume, and the feasibility of mining the deposit, through measured block modeling. Chemical analyses, petrography, and QA/QC will be part of this stage, which will be programmed in detail according to the results of the previous stages. METALLURGICAL PROCESS ROUTE: The best beneficiation methodologies for the primary ore will be evaluated, aiming to define optimal recovery and purification models for the gold in the potential deposit.

Explore detailed geological, geochemical, and resource modeling data confirming the presence of rare earth elements (REEs) such as Nd, Pr, Dy, and Tb in Bahia, Brazil. Discover the project's strategic value for clean energy and critical mineral supply Rare Earths Itaquara - BA The area of mining process no. 871.535/2023 occupies 1999.90ha and is located in the municipalities of Itaquara and Santa Inês, Bahia, Brazil. HIGHLIGHTS RESERVES Based on geochemical interpolation and volumetric modeling using raster algebra in QGIS, the estimated mineralized volume is approximately 6.9 billion m³. Considering a density of 2.8 t/m³ and a representative thickness of 5 m, this corresponds to a tonnage of 19.34 million tons and an estimated content of 12,568 tons of Total Rare Earth Oxides (TREO), confirming the deposit's significant potential. GRADES Geochemical analyses revealed TREO grades above 1,000 ppm in key areas, with notable concentrations of Nd, Pr, Dy, and Tb—the most strategic elements for permanent magnet applications. In samples such as S3 and S4, Nd+Pr exceeded 20% of the total TREO, highlighting the technological and economic value of the deposit. LOCATION The deposit is located in the municipalities of Itaquara and Santa Inês/BA, about 270 km from Salvador and 70 km from Jequié, a regional hub with logistics infrastructure. Access is via paved roads to nearby urban centers, with well-maintained rural roads leading to the project area. This provides excellent logistics and low access costs for future phases.

Deep Dive BRM Podcast 00:00 / 17:48 LOCATION AND ACCESS ROUTES The ANM Process 870.353/2023 is located predominantly within the municipality of Itaquara, with its northern section extending into the neighboring municipality of Santa Inês, in the state of Bahia. The main access to the region is via Highway BR-116, one of the country's major routes, connecting Salvador to Bahia's interior and other states. From BR-116, access is provided by state roads BA-250 and BA-420, which connect the municipalities of Jaguaquara, Santa Inês, and Itaquara, leading to rural roads that reach directly into the area of interest. The unpaved roads leading into the site are, for the most part, in good condition, allowing conventional utility vehicles to operate throughout most of the year. The site lies approximately 270 km from Salvador, the state capital, with fully paved access to the nearest urban centers. The city of Jequié, a regional hub with logistical infrastructure and support services, is located about 70 km from the study area by road and serves as the main reference center for lodging, supplies, and technical-operational support. PHYSIOGRAPHIC ASPECTS CLIMATE AND VEGETATION The northern region of the municipality of Itaquara/BA, on the border with Santa Inês/BA, has a hot tropical climate with a well-defined dry season, classified under Köppen's climate classification as Aw. This climate is characterized by high temperatures throughout the year, with an annual average of approximately 23 °C, and the hottest months occurring between December and March. Annual average rainfall is around 800 mm, concentrated mainly in the summer, between November and March, while the winter months present significantly lower rainfall volumes, clearly characterizing a dry period. Regarding vegetation, the region is mostly within the Atlantic Forest biome, although it has suffered significant deforestation and fragmentation over the years. The original vegetation is predominantly composed of semideciduous seasonal tropical forest, with remaining areas made up of secondary forest fragments and riparian forests along watercourses. SOIL AND HYDROGRAPHY The soils dominating the area are typical of tropical regions over ancient crystalline rocks. Dystrophic Red-Yellow Latosols predominate, with a lesser occurrence of dystrophic Red-Yellow Argisols in specific topographic positions. According to Embrapa, Latosols and Argisols are deep, highly weathered soils with low natural fertility, generally acidic and with high aluminum saturation. This aligns with the local soils, described as dystrophic latosols (low base content) and even an alic variation (extremely acidic) in certain sections. These are well-drained soils, developed over Precambrian basement rocks (granites, gneisses, charnockites, etc.), presenting medium to clayey texture. Although chemically poor, these soils have good depth and structure, making them suitable for agriculture and livestock farming. The area lies on the interfluve of two important hydrographic basins: the Jiquiriçá River Valley to the north/east and the Contas River basin to the south/west. The Santana River, located closer to the project site, is a major tributary of the Jiquiriçá River. The Jiquiriçá River is the main regional watercourse, draining east-northeast through a longitudinal valley where several towns of the so-called Jiquiriçá Valley are located (Figure 3). Near the project area, other tributaries such as the Almas River, Casca River, and Andaraí River are also present, among other medium-sized streams. These drainages display a seasonal regime, with floods in the rainy summer and reduced flows in the dry winter. In the southwestern sector, the slopes already drain into the Contas River, which flows southward until it empties into the Atlantic near Itacaré. Figure 1. Soil classification map (EMBRAPA, 2020) in context with the Jiquiriçá River basin RELIEF The region's relief is quite rugged, falling within the geomorphological units of south-central Bahia. Notable features include the Marginal Ranges to the east (residual foothills of the coastal plateau) and the Central Massif to the west, interspersed with hills and pre-coastal tablelands extending toward the coast. Among these features are elevated plateaus such as the so-called "Planalto dos Geraizinhos" and flattened pediplane surfaces in the interior backlands. In the field, the topography is characterized by rounded hills and mountain ranges, with deeply incised valleys and flat bottoms (Figure 2). Altitudes range from approximately 200–300 m in the lowest parts of the river valleys to about 700–800 m at the tops of local mountain ranges. Figure 2. Southern Sector View of the Area REGIONAL GEOLOGY The area covered by ANM Process 870.353/2023 is located in a complex geotectonic setting, shaped by the collision between the Jequié and Itabuna-Salvador-Curaçá Blocks during the Paleoproterozoic. This tectonic interaction resulted in intense granulite-facies metamorphism and led to a diversified stratigraphy dominated by high-grade metamorphic rocks. GEOTECTONIC CONTEXT The area lies within the central portion of the São Francisco Craton, in the region known as the "Southern Bahia Granulite Belt," where Archean and Paleoproterozoic terrains of the Jequié Block are exposed. This block constitutes one of the main geological compartments of the São Francisco Craton in Bahia and presents distinct petrological and structural characteristics. The geotectonic evolution of the region is marked by significant collisional events. During the Paleoproterozoic, between 2.1 and 1.9 Ga (billion years ago), the Jequié Block was overridden by the Itabuna-Salvador-Curaçá Block (ISCB) in a major collisional event. This collision triggered intense crustal thickening, deformation, and high-grade regional metamorphism, leading to the formation of extensive granulitic terrains. The suture zone between these two tectonic blocks represents a geotectonically significant structural feature. Recent studies using structural and geophysical data have contributed to a better delineation between these blocks. (Figure 3 – Tectonic domain map showing the current configuration of the Jequié Block) Figure 3. Map of Tectonic Domains showing the current configuration of the Jequié Block STRATIGRAPHY The Jequié Block is an orthoderived granulitic complex composed of charnockitic, charnoenderbitic, and enderbitic rocks. These rocks are mesocratic to leucocratic, medium- to coarse-grained, with well-defined gneissic banding and occasional migmatization, along with supracrustal rocks that are also granulitized. Process 870.353/2023 is located in a region geologically classified as the Jequié Complex, comprising the following lithostratigraphic units from base to top (Figure 4): A34jsp – Supracrustal rocks consisting of bands, enclaves, and boudins of basic granulites (basalts and basaltic andesites), quartz-feldspar granulite bands, garnet- and orthopyroxene-bearing or barren cherts/quartzites, graphite schists, banded iron formations, aluminous-magnesian or kinzigitic granulites, and mafic-ultramafic rocks. A34jb – Basic granulites, dark green to black, fine- to medium-grained. Occur as bands or enclaves with centimeter- to meter-scale thickness. Composed of plagioclase, orthopyroxene, clinopyroxene, quartz, opaque minerals, and apatite. Hornblende, biotite, and garnet are occasionally present. A34jch – Serra do Timorante Unit: Granulitic tonalite to granodiorite, gray-brown, medium- to coarse-grained, with feldspar porphyroclasts and localized garnet occurrences. Penetrative foliation and tectonic contact with adjacent units. A34jed – Amargosa-Nova Canaã Unit: Granulitic granite to tonalite interlayered in centimeter-scale bands, gray-green to gray-brown in color, medium- to coarse-grained.

Locally interlayered with metamafic and metaultramafic rocks. A34jq – Ubaíra Unit, quartzite lithofacies: White-gray to yellow quartzite, sometimes ferruginous, medium- to fine-grained, foliated, and occasionally folded. Locally interlayered with banded iron formation levels. A4jch – Santa Inês–Volta do Rio Unit: Granulitic granite to granodiorite, gray-whitish to light greenish-gray, medium- to coarse-grained, with feldspar porphyroclasts and mafic mineral aggregates, banded, foliated, and occasionally mylonitized. Interlayered with deformed pink syenogranite veins or bands. PP23chb – Brejões Charnockites: Foliated and sometimes banded, coarse- to very coarse-grained, gray-green to dark gray in color. Composed of megacrystals of mesoperthite and quartz immersed in a matrix of mesoperthite, quartz, hornblende, orthopyroxene, clinopyroxene, and subordinately, perthitic microcline, interstitial plagioclase, and biotite. Accessory minerals include opaques, apatite, zircon, myrmekite, sericite, bastite, and rare garnet crystals. PP3lch – Leucocharnockites with garnet and cordierite are massive, medium- to coarse-grained, sometimes fine-grained, and gray-green when fresh, turning whitish upon alteration, highlighting idioblastic garnet crystals. Composed of mesoperthite, quartz, garnet, orthopyroxene, plagioclase and/or antiperthitic plagioclase, biotite, opaques, and cordierite. Clinopyroxene, zircon, and monazite are accessory minerals, while sericite, muscovite, bastite, chlorite (from orthopyroxene alteration), and myrmekite, along with hornblende and biotite, represent retrograde metamorphic phases. NQd – Detrital-lateritic deposits: Unconsolidated to poorly consolidated deposits formed by residual soils with sandy, sandy-clayey, clayey-sandy, and clayey-silty compositions, colored from gray-yellowish to reddish-orange. Contain gravel layers with rounded quartz pebbles. Totally or partially lateritized with ferruginous lateritic crust; levels of lateritic concretions at the contact with the substrate. Figure 4. Geological map of the Amargosa Sheet (SGB, 2009) adapted with updates from the Jequié Sheet (SGB, 2020) and Manuel Vitorino (SGB, 2020) STRUCTURAL GEOLOGY The evolution of the Jequié Block is characterized by the following geological events: 3.4 Ga to 3.2 Ga: Formation of an initial continental crust generated by geological processes consistent with a two-stage model, considered responsible for the generation of TTG associations; 3.2 Ga to 2.9 Ga: Extensional tectonics with the formation of supracrustal rocks due to the development of an intracratonic basin formed by the separation of the Gavião Block to the west and the Jequié Block to the east; 2.4 Ga: Tangential tectonics with frontal ramp structures and strike-slip components, thrusting the Jequié Block over the Contendas-Mirante Greenstone Belt; 2.0 Ga: Peak of regional metamorphism in the Jequié Block at granulite facies. WORKS CARRIED OUT AND RESULTS OBTAINED As planned, the activities conducted are presented in the following items of this section, in chronological order. SURVEYS, BIBLIOGRAPHIC AND CARTOGRAPHIC STUDIES Prior to and during the execution of field activities, bibliographic, cartographic, and geoscientific data were collected and systematized to characterize the regional and local geology of the research area. Mineral occurrences registered in the Mineral Resources Information System – GeoSGB (CPRM) and the database of the Companhia Baiana de Pesquisa Mineral – CBPM were consulted. High-resolution satellite imagery (Esri Imagery – Alos 30, ESRI-2025 repository) was also used, in addition to geological maps of the Amargosa, Jequié, Jaguaquara, and Maracás sheets, all at a 1:100,000 scale, prepared by the Geological Survey of Brazil (CPRM, 2009 and 2020). In the field, a geological reconnaissance was carried out throughout the area to identify potentially promising targets for sand, for subsequent geological detailing and drilling grid definition. Additionally, updated topographic maps from open sources (OpenStreetMap) and regional geophysical surveys provided by CBPM and SGB were analyzed, with emphasis on magnetometric and gamma-spectrometric data. Geographical and spatial data were organized in a georeferenced database, digitized and processed within the QGIS software environment (version 3.40.5 – Bratislava). This integrated database supported the preliminary geological interpretation of the area and provided the technical basis for planning the field campaigns. GEOLOGICAL RECONNAISSANCE Fieldwork was mostly carried out by ARCANGEO – Soluções em Geologia e Meio Ambiente, currently responsible for the Mineral Potential Assessment (DPM). Field activities took place in May 2024 and consisted of a systematic geological reconnaissance campaign aimed at identifying, describing, and evaluating the main lithological units present in the area of mining process no. 870.353/2023. The methodology included traverses with georeferencing of observation points, outcrop descriptions, structural observations, sampling of soil, rock, and pan concentrates, and photointerpretation of satellite images previously processed in a GIS environment. During the field surveys, 66 strategic points distributed across the entire polygon were visited and classified as control, outcrop, and sampling points. (Figure 5) Figure 5. Map of visited points, adapted from ARCANGEO, 2024 The Archean units of the Jequié Block—granulites, charnockites, etc.—define much of the area. These lithological units occur both in the highland regions and in the flatter portions of the area, often covered by thick layers of clayey soil and residual sediments. Figure 6. Map of the Anomalous Magnetic Field vs. Tilt Derivative of the Analytic Signal, based on original data from CBPM As shown in Figure 6, applying the tilt derivative of the analytic signal to CMA-derived data is recommended for mapping structures and mineral exploration targets, enhancing features that are not clearly identified by individual methods. One advantage of this method is that the tilt derivative provides better resolution of body boundaries by equalizing the amplitudes of the CMA. Thus, this technique simultaneously enhances the response of bodies located at different depths. In delineating faults in the area, it is possible to outline the SW/NE fault using negative CMA and confirm it with the tilt derivative, which proves that this regional structure is large-scale and directly influences the definition of drilling targets. During geological reconnaissance, the predominance of soils grading from yellowish silt to intensely red clay suggested a favorable environment for the hosting of ionic clays (IC). Additionally, the presence of magnetite and heavy minerals in hydraulic flow channels supports the chemical and weathering disaggregation of granulite minerals and their remobilization in low-energy environments. Figure 7. Heavy magnetic minerals in drainage channels on shallow soil The rocks found near the area, as shown in Figure 8, vary in color from dark green to yellowish, with a predominance of melanocratic, cohesive types, composed of quartz, plagioclase, biotite, pyroxene, magnetite, and opaque minerals, typical of granulite/leucocharnockite. Garnet was occasionally observed, especially in paraderived protoliths. Figure 8. Macroscopic indicators of iron and manganese oxides Texturally, these rocks are predominantly isotropic, with weak foliation and limited regional structural orientation trending N50/70. The presence of hypersthene (dark green pyroxene), opaques, and alkaline hornblende are characteristic minerals of the classic charnockite of the Jequié Block. Despite minor mylonitic foliation, it is possible to classify these rocks into host rock, granulite/leucocharnockite, younger dark green charnockite in amphibolite metamorphic facies, and contact zones showing signs of mylonitization, common in the local geotectonic context. These mylonitized zones—transpressional faults—are key structures for the concentration of Rare Earth Elements, as well as other metals. GEOCHEMICAL SURVEY The geochemical survey of the area related to ANM process 870.353/2023 employed two main laboratory analysis methods: X-RAY FLUORESCENCE (XRF72FE) This method was applied to rock samples (including rock powder) and involves the emission of X-rays that interact with the atoms in the sample, generating characteristic signals for each element. The analysis is fast, non-destructive, and efficient for major elements, though it has limited sensitivity for trace and light elements. ICP-MS / ICP-OES (ICP95A / IMS95A) Soil samples, pan concentrates, and sediments were analyzed using ICP, following acid digestion. This technique enables the quantification of trace elements with high precision due to its high sensitivity and multi-element capability, making it ideal for rare earth elements (REE). However, the method is costly, destructive, and dependent on laboratory infrastructure. Responsible Laboratory: The analyses were conducted by SGS GEOSOL Laboratórios Ltda., accredited with ISO 9001:2015 and ISO 14001:2015 certifications (ABS numbers 32982 and 39911), ensuring international standards of quality and environmental management. To create raster images of the calculated attributes, the ioGAS 8.20 software was used. The raster of the processed data and its respective legend were exported in SVG format. MAP OF TOTAL RARE EARTH OXIDES (TREO % and ppm) Figure 9. Map of Total Rare Earth Oxides in percentage. Map generated using ioGAS 8.20 software Figure 10. Total Rare Earth Element Oxides in ppm. Generated using ioGAS 8.20 software The TREO maps in percentage (Figure 11) and in ppm (Figure 12) indicate that the highest concentrations are located in the central and northern regions of the polygon, mainly near samples S3, S4, SD2-C2, SD3-C3, and SD1-C1. Values exceed 1000 ppm in certain areas, suggesting strong mineral potential. There is a clear correlation with geological structures (faults and anticlines). THORIUM MAP (Th ppm) Figure 11. Distribution of Thorium (Th) content in ppm. Generated using ioGAS 8.2 software The element Th (Thorium) appears with elevated values in the northern part of the area, indicating a possible presence of monazite or other REE-bearing minerals. Samples S3 and S4 are closest to the hotspots. Th anomalies are associated with major REE deposits within the Jequié Block, currently referred to as the SPVR – Volta do Rio Plutonic Suite, where companies like Equinox Resources, BRE, and GMN are conducting extensive mineral exploration projects. MAP OF LIGHT MAGNETIC RARE EARTH OXIDES (mREO: Nd2O3 + Pr6O11) Figure 12. Map showing the distribution of total concentrations of Light Magnetic Rare Earth Oxides (mREO). Generated using ioGAS 8.2 software The distribution closely follows that of the TREO, with the highest values concentrated in the central portion of the block, emphasizing the presence of light REEs used in permanent magnets. Currently, Neodymium (Nd) and Praseodymium (Pr) are the most sought-after among the 17 Rare Earth Elements, mainly due to their high market value and wide technological applications. MAP OF HEAVY MAGNETIC RARE EARTH OXIDES (Dy2O3 + Tb4O7) Figure 13. Map showing the distribution of total concentrations of Heavy Magnetic Rare Earth Oxides (HREO). Generated using ioGAS 8.2 software The anomalies detected in the northern and northeastern areas, especially near samples S4 and SD3-C3, suggest the presence of heavy REEs with significant technological potential. Dysprosium (Dy) and Terbium (Tb) are combined to assess the economic and technological value of a rare earth deposit, particularly in the permanent magnet industry. Deposits with meaningful concentrations of these two oxides are considered especially valuable, as Dy and Tb are much rarer and more expensive than Nd and Pr. MAPS OF HREO AND LREO (Heavy and Light Rare Earth Oxides) Figure 14. Map of the distribution of total Light Rare Earth Oxide (LREO) contents. Generated using ioGAS 8.2 software Light Rare Earth Elements (LREO) are widely distributed throughout the central portion of the study area, indicating a distinct concentration environment. Due to their higher mobility, these elements often form supergene deposits in structurally confined settings, as illustrated in the map. They are also more susceptible to weathering processes. Figure 15. Map of the distribution of total Heavy Rare Earth Oxide (HREO) contents. Generated using ioGAS 8.2 software Heavy Rare Earth Elements (HREO) are predominantly concentrated in marginal sectors and the northern part of the area, suggesting a possible zoning in the mineralization. Due to their higher atomic weight and specific geochemical affinities, these elements are relatively immobile, tending to remain near their source area. VOLUME ESTIMATION OF RARE EARTH ELEMENTS (REEs) The volume estimation presented in this report was carried out based on point geochemical data interpolated using the IDW method, converted into a raster surface, and subsequently analyzed through map algebra in QGIS. This methodology allows for a preliminary estimation of REE volume and content, based on assumptions regarding density and representative thickness. It is emphasized that the values obtained are indicative and must be validated through subsequent systematic sampling and drilling campaigns, in accordance with the guidelines of the National Mining Agency (ANM) for the purpose of mineral resource classification and declaration. ELEMENTS OF RASTER ALGEBRA AND IMPLICIT OBJECTIVE To describe the volume estimation (cubagem) process of Rare Earth Elements (REEs), based on point geochemical data and the application of spatial interpolation techniques and raster algebra in the QGIS software. DATABASE The database used consists of a CSV file containing sampling points with the following columns: UTM Coordinates (Easting, Northing) Elevation (m) TREO_ppm (concentration of REE oxides in ppm) PROCESSING IN QGIS Spatial Interpolation: IDW with 10m pixel, field TREO_ppm. Clipping with Polygon: using “Clip Raster by Mask Layer”.

Figure 16. Inferred Resources Map. Prepared using QGIS 3.40 FINAL CONCLUSIONS The Final Exploration Report for ANM process No. 870.353/2023 provides robust technical evidence of significant rare earth element (REE) and iron ore mineralization in the municipalities of Itaquara and Santa Inês (Bahia), within the requested area. The activities carried out — from bibliographic, geological, and geochemical surveys to laboratory analyses and raster algebra modeling — were conducted in accordance with the parameters established by the National Mining Agency (ANM Resolution No. 94/2022). The concentrations detected of neodymium (Nd), praseodymium (Pr), dysprosium (Dy), and terbium (Tb) — all of high technological and strategic value — reveal considerable economic potential, especially in the northern and central portions of the study area. Geostatistical modeling indicated an estimated volume of 6.9 billion m³, resulting in approximately 12,568 tonnes of inferred REEs, confirming the project's value for future drilling and feasibility phases. With low logistical costs, accessible regional infrastructure, favorable climate, and a highly prospective geological context, the area represents a unique opportunity for the advancement of mineral projects focused on energy transition and clean technologies. BRM therefore concludes that the results obtained not only justify the project's viability but also strengthen the company's strategic position in the national and international critical minerals market.

Strategic Gold and Quartz deposits in Caturama, Bahia. BR Mining presents a promising investment opportunity in Brazil’s mineral-rich interior, with high exploration potential. Gold & Quartz Caturama - BA The area of mining process no. 871.977/2021 occupies 174.90ha and is located in the municipality of Caturama, Bahia, Brazil. HIGHLIGHTS GOLD RESERVES The project has substantial potential for further exploration as only a small portion of the "NE Target" area has been researched at very shallow levels of approximately 1m in depth. Even with this preliminary research, it is estimated to have 150kg of gold with easy extraction. GEOLOGICAL FORMATION This gold deposit contains both primary and secondary gold ore. Primary ore is gold found within the rock itself, associated with quartz veins and geological structures. Over time, weathering releases gold from the primary ore, creating secondary ore in the form of gold dust and nuggets dispersed in the soil and water. This site contains both types of deposits, increasing its potential value LOCATION the region lacks any existing industrial mining activities. This means a new project wouldn't face direct competition for resources or market share. However, the report also emphasizes the need for careful planning and execution, particularly regarding approvals and monitoring, due to the absence of established gold mining practices in the region PROJECT VIABILITY This report confirms a profitable gold deposit in Bahia, Brazil, containing both primary (in rock) and secondary (in soil/drainage) gold ore. The deposit, called the “NE Target,” shows promising results, especially in the "Target NE-B" area. While challenges exist, the confirmed presence of economically viable gold and the potential for further exploration make this a promising project. Tune in to our exclusive podcast showcasing the Gold & Quartz deposit in Caturama, Bahia. Deep Dive BRM Podcast 00:00 / 15:29 LOCATION AND LOGISTICS The mining process area No. 870.977/2021 covers approximately 175 hectares and is located on the municipal borders between Rio do Pires and Caturama, in Bahia, Brazil. Access from the nearest town, Rio do Pires, to the visited areas is via an 8 km dirt road in good condition. Rio do Pires is approximately 720 km from Salvador, the state capital, following the longer but better-quality route, which passes through Feira de Santana, Maracás, Brumado, and finally Rio do Pires. Rio do Pires has limited infrastructure to support a mining project, as it offers few hotels/inns, lacks specialized workshops, and does not provide heavy equipment rental services, among other factors typical of a small town. However, the city of Caetité-BA, located 150 km south of the visited areas, has better infrastructure to meet such needs Fig 1. The mapped polygon is accessed through local roads. A notable feature within the area is the “Pedra do Boi”, the largest rock outcrop present in the region. GEOTECTONIC EVOLUTION AND REGIONAL GEOLOGY Regionally, the mining processe is set within the geological context of the Espinhaço Supergroup, specifically in the western domain of the Chapada Diamantina, involving primarily the Paraguaçu and Rio dos Remédios Groupsaccording to older studies. However, the book “Geologia da Bahia: Pesquisa e Atualização, 2012” references more recent works, such as “Guimarães et al., 2005” and “Loureiro et al., 2008,” which propose a different compartmentalization for this mapped area by including the Serra da Gameleira Formation at the base of the stratigraphic column. This updated compartmentalization will be used as the reference for the interpretations presented here. The crystalline basement is composed of rocks from the Paramirim Complex. The following sections provide key descriptions of these groups, from the base to the top, with the aim of correlating the literature with the field mapping observations. Fig 2. Regional geology with emphasis on the distribution of the Rio dos Remédios Group and the Serra da Gameleira Formation, the main regional influences in the area. PARAMIRIM COMPLEX (CRYSTALLINE BASEMENT) It is located throughout the entire valley of the Paramirim River and is the most prominent lithostratigraphic unit in this valley domain. According to Arcanjo et al. (2000), it is predominantly composed of orthogneisses, which can be classified as augen-mylonitic and migmatitic. However, Sá et al. (1976) describes this complex through four lithological groups: banded gneisses with anatectic features, (hornblende)-biotite orthogneisses tonalitic-granodioritic migmatitic, biotite orthogneisses tonalitic to granitic, migmatitic gneisses, and associated granitic rocks: augen monzogranitic gneisses mylonitized and granodioritic orthogneisses. The rocks of the Paramirim Complex are typically polydeformed and display a progressive mineralogical association consistent with the high amphibolite facies. The rocks are dated as Archean by Mascarenhas & Garcia (1989). SERRA DA GAMELEIRA FORMATION It is interpreted as a sequence of metasedimentary rocks with a total package thickness of up to 200 meters, where a wide variety of lithotypes can be found, including metaquartzarenites ranging from coarse to fine, metargillites, metaconglomerates (both polymictic and oligomictic), metarcoses, etc. The Serra da Gameleira Formation lies on the crystalline basement rocks of the Paramirim Complex, with a total package thickness ranging from 70 to 200 meters, and is overlain by the rocks of the Rio dos Remédios Group through a regional erosional unconformity. It is interpreted by most authors as originating from a period of crustal thinning before the opening of a rift-type basin, where sediments were accumulated in desert environments through aeolian processes, followed by debris flows and lacustrine sedimentation, which completed the deposition of this formation. RIO DOS REMÉDIOS GROUP This group can have direct contact with the basement rocks, but erosional contacts predominate with the Serra da Gameleira Formation at the base and the Paraguaçu Group at the top. This group is subdivided into three formations: Novo Horizonte, Lagoa de Dentro, and Ouricuri do Ouro. Of the cited formations, Novo Horizonte, located at the stratigraphic base, holds significant metallogenetic importance, as it contains volcanic rocks (such as metadacites, metarriolites, metaquartz porphyries, and metaphenoandesites) that have been deformed and altered by various hydrothermal processes, resulting in important mineral occurrences, including gold, crystals, barite, and cassiterite. This formation was formed through four magmatic volcanic events. Just above, the Lagoa de Dentro Formation has a maximum thickness of up to 850 meters and consists of rocks divided into three associations: at the base, metasiltstones, metargillites, impure metarenites with possible levels of oligomictic conglomerates, calcitic metarcoses, and metamuds; above that, there are metarenites with wavy markings in the intermediate zone; and at the top, metapelites, metasiltstones, and metarenites that are metasomatized. At the top of the Rio dos Remédios Group, is the Ouricuri do Ouro Formation, composed of five associations of siliciclastic rocks deposited during a period of continental terrigenous sedimentation in an era of significant tectonic instability. These include polymictic metaconglomerates, metagravelites, metarcoses, metaquartzarenites, and metarenites with feldspar, among others. The most striking characteristics of this formation are the presence of conglomerates formed by gravitational flows and the high variation of lithofacies that constitute it. PARAGUAÇU GROUP The Paraguaçu Group is stratigraphically positioned above the basement and/or above the rocks of the Rio dos Remédios Group, in both cases over erosional unconformities. This group is subdivided into two formations: Mangabeira and Açuruá, and, as noted by Derby (1906), it consists of a thick package of quartzites, metasiltstones, metapelites, and discontinuous layers of metaconglomerates. This group is defined by some authors as a supersequence of rocks deposited in a wide, shallow basin formed during passive subsidence with little tectonic activity. Fig 3. An example of the stratigraphic columns that comprise the stacking of the previously mentioned metasedimentary rocks, placing the Serra da Gameleira Formation at the base of the sequence and the Paraguaçu Group at the top. REGIONAL TECTONIC EVOLUTION Several authors, such as Alkmin et al. (1993), Rocha & Dominguez (1993), Costa & Inda (1982), etc., describe the regional tectonic evolution influencing the areas mapped here as belonging to the development of the “Paramirim Corridor”, a zone located between the western edge of the Chapada Diamantina Group and the eastern edge of the Serra do Espinhaço Sententrional. The structural evolution of this deformation corridor was complex, leading to different hypotheses among authors regarding the chronology of the events of its formation. However, in summary, it is understood that the Paramirim Corridor was generated from a marginal zone of an ancient rifting (crustal opening), which, after sedimentary deposits associated with basin formation, advanced to a closing (compressional) phase with fault reactivation and exposure of rocks of different natures intercalated by regional structures. The “Basic Geological Survey Program of Brazil – Paramirim Valley Project, 2000”, carried out by CPRM in partnership with CBPM, describes the entire evolution of this compartmentalization in 8 distinct stages, with the last stage being the inversion (closure) of the Espinhaço rift and the uplift of the Paramirim block. Bringing the knowledge of this evolution to the reality of the mapped areas, it is understood that transcurrent and compressive structures are common, primarily characterized by shear zones and the restructuring of rocks, forming mylonites over large territorial extents, especially in transition zones between metasedimentary units and the crystalline basement. QUARTZITES AND QUARTZ QUARTZITES The metasedimentary unit also features some types of quartzites and metarenites. However, in most representative outcrops, certain characteristics are less favorable, such as the colors (highly variable but generally tending toward gray) and the fracture systems, which are always present.. Despite this, a highly interesting rock layer for producing high-value blocks was identified in the area. It consists of sheared white metarenite with quartz veining found at the "Garimpo do Lu," which is also associated with the primary gold source of the central target. This rock does not exhibit significant thickness but spans approximately 180 meters in outcrop length, with massive and minimally fractured bands. Most importantly, it displays excellent physical and textural quality, significantly increasing its market value.

These are associated with almost all types of ductile and brittle structures observed in the field, such as faults, shear zones, and those embedded within the foliation of the rocks. Despite the widespread spatial distribution of these quartz veins across the area, the metasedimentary unit, particularly associated with quartzites and metarenites, shows the most significant occurrences of veins. Numerous old crystal mining sites ("catas") and large outcrops were identified in these units. The high economic interest in this material is justified by its apparent chemical quality and purity, likely consisting of rocks with a high silica content and few contaminants. Some veins are so significant that they suggest the potential for evaluation as ornamental stone (block production). The photographs below illustrate some of the "findings" from quartz crystal mining and depict one of the most promising veins identified during the mapping process. This vein, located at point P464, features large dimensions and very promising physical characteristics.

Sample of high-purity quartz vein from point P464 1/3 IDENTIFIED MINERAL POTENTIAL OF GOLD GOLD ORE The existing and known gold within the mapped area, as previously explained, is associated with a contact zone between two different units. This zone is characterized by intensely deformed rocks and the presence of quartz veins/veinletsassociated with black/greenish volcanic rock. During a preliminary visits, samples collected from this contact zone (CZ) revealed positive gold anomalies, further supporting the presented hypothesis. This zone is understood to be the source of the detrital gold present in the mined colluvium.

Example of gold collected by prospectors in the colluvium of the Central Target. GEOLOGICAL CONTEXT OF GOLD MINERALIZATION In simplified terms, the gold in the researched target is associated with quartz vein layers containing sulfides and hydrothermal iron oxides. These zones are correlated with fault or shear structures where the quartz is embedded. The description above refers to PRIMARY ore, meaning the gold contained in the rock. Over time, through weathering processes, these layers release detrital gold in the form of dust and nuggets into the soil and drainage systems, forming SECONDARY ore. Due to the existence of both types of deposits in the area (gold in the rock + gold in the soil/drainages), the exploratory research was conducted to investigate both. - - Screenshot 2024-11-21 at 2.23_edited - 1/3 Illustrations of gold-mineralized rocks in the Rio do Pires/Caturama project region.

DETAILED MAPPING The layers of rock with high potential for gold presence were identified, along with the definition of the topographic correlation between the mineralization styles (primary and secondary), which allowed for the projection of the quantity and spatial distribution of the trenches. During the mapping and planning phase, the study area was subdivided into two sectors: "Target NE-A" and "Target NE-B", facilitating the internal data correlation. The results of the subsequent phases to be described will be presented separately. Fig 4. Detailing of the two sub-targets defined for research within Target NE. OPENING OF WELLS AND TRENCHES This stage was carried out with a Caterpillar 416 4x4 backhoe. In total, 4 trenches were opened in Target NE-A and 9 trenches in Target NE-B. The length and maximum depth of all trenches varied according to the type of geological material identified, but the width remained standard, around 90cm. - - - - 1/3 Illustration of the trenching operation and excavation process. Fig 5. Location of the opened trenches. DESCRIPTION OF THE TRENCHES. The description of the trenches (TRs) was carried out with the collection of various data, such as point-by-point coordinates, altitudes, compass direction, and geology according to the type of existing information. All trenches crossed the soil and gravel layers down to the hard rock below (saprolite). In the case of the gravels and soils, characteristics of the predominant cobble dimensions, matrix/cobble ratio, cobble types, matrix type, thickness, and the likely level of rework by former mining activities were described. Example of a zone where a layer of material disturbed by miners (a mixture of waste and soil) lies o In b) it is possible to observe that in some zones the soil is thin, practically without virgin mate Finally, in c) a large layer of gravel preserved in an argilo-sandy matrix can be observed. The larg Example of a zone where a layer of material disturbed by miners (a mixture of waste and soil) lies o 1/3 Regarding the rocks, the main structures were evaluated, such as faults/fractures, shear zones, and foliation, as well as the division of various lithotypes, classifying them according to their importance for gold deposits. An example of this includes the primary ore layers, where channel sampling was carried out. - - - - 1/3 These pictures illustrate primary ore layers identified during the opening of TR6-B, TR3-B, and TR3-A, respectively. SAMPLING The sampling consisted of collecting rock samples (primary ore) and gravel/soil samples (secondary ore). Primary ore samples (rock): As mentioned earlier, in some trenches, layers of gold-bearing rock were found. In these locations, detailed descriptions of the material were made, and channel samples were collected. A channel sample consists of collecting the gold-rich rock and its surrounding matrix, allowing for a more accurate assessment of the average grade of that zone. A total of 6 channel samples were taken from 6 different trenches. Throughout the report, some spreadsheets will provide additional data on this sampling. Fig 6. Example of channel sampling, in this case from AM-PR-TR3 in TR3-A, where 100 cm by 10 cm of mineralized material and surrounding sterile matrix were collected. Secondary ore sampling (soil/gravel): A total of 29 samples were collected in Target A and 39 samples in Target B. Several control steps were taken for each trench, such as: Definition of sample spacing; Determination of the total length of the sampling area; Observation of the material type (mined gravel or virgin gravel); Cleaning of collection tools (tarps + tools). For each defined sample, collection was carried out as follows: In areas with preserved (virgin) gravel, only this material was collected consistently across its thickness for the entire length of the sample; In areas with preserved gravel mixed with soil/gravel from previous mining, all of this material was included in the sample. In all trenches and for all samples, the collection process followed these steps: Material removal from the trench wall; Screening with a 0.35mm granulometry; Classification (ratio of sand, clay, and gravel); Packaging and titling; Weighing. Note: Only TR7B was sampled in raw material without screening. DATA TREATMENT The collected samples were panned for: heavy concentration, gold spotting + description, and finally for chemical characterization. All data obtained in all the stages mentioned were considered for the final interpretation of results. Maps and geoprocessing products were created and helped define the spatial distribution of the information on the surface and determine the indicated volume of mineable ore. RESULTS OBTAINED In summary, both targets NE-A and NE-B showed predominantly positive results for the presence of gold, with target NE-B being the most significant in terms of grade and volume. MAP OF ISOCHORES Based on the results of the chemical analyses to be conducted, interpretative maps of gold concentration density and colluvium thickness will be generated, providing information on average grades for the deposit. INDICATED VOLUME For the estimation of the existing ore volume, some crucial points must be recalled: The calculations to be presented refer ONLY to the SECONDARY ore, i.e., the gold dust deposit in the soil and gravel of the area; The calculations considered EXCLUSIVELY the gold identified in the panning count, remembering that: A manual process was performed, without the aid of precision tools such as a bench magnifying glass or fine vibrating table, for example; The samples were panned, which made it impossible to detect coarser gold, so only grains with a maximum granulation of 0.30mm could be identified. The volumes presented will be treated as INDICATED for the NE-A and NE-B targets. When considering the dimensions of the entire mineralized area outside these targets, the volume will be treated as INFERRED (lower degree of information). CONCLUSIONS ABOUT THE GEOLOGY AND ECONOMIC POTENTIAL OF THE AREA: The existence of a mineral deposit of gold in economic ore conditions has been proven, where it is possible to extract and benefit the ore for profit, considering the secondary ore. however, the primary ore (rock) still needs further evaluation for more precise definitions; Only two small polygons within the ne target area (ne-a and ne-b targets) have been well researched so far, which considerably increases the exploratory potential of the project as a whole, which has yet to be fully explored. in addition to the remaining polygon of the ne target area (more than 70%), there are at least two other mapped targets with great potential; The ore in the area varies from sandy to clayey, and it also contains a significant amount of very fine gold, all distributed between packages of virgin gravel and soil disturbed by former miners. these characteristics make it difficult to accurately estimate the volume, grade, and waste/ore ratio. ABOUT THE STRATEGIC CHARACTERISTICS OF THE PROJECT (NE TARGET), IT CAN BE SAID THAT: They are positive in terms of surface conditions and access, however, challenges will arise regarding water supply and energy usage; The region where the project is located does not present industrial mining operations in progress. therefore, any operation to be initiated in the area must be well planned concerning approvals, monitoring, and environmental issues.

Explore premium Granite from Floresta Azul, Bahia. BR Mining connects buyers to top-quality Brazilian granite, ideal for construction, design, and export markets. Granite Floresta Azul - BA The area of mining process no. 870.935/2021 occupies 41,01ha and is located in the municipality of Sento Sé, Bahia, Brazil. HIGHLIGHTS LOGISTICAL FRAMEWORK The location has good logistical conditions to support a mining project. It is close to the city of Floresta Azul and has access to infrastructure in nearby cities, including hotels, specialized workshops, heavy equipment rentals, banks, and medical services in Ibicaraí and Itabuna. Additionally, the area is near energy and water sources GOLOGICAL CONTEXT The regional geological context presents opportunities to identify different lithotypes within the evaluated area due to the diversity of metamorphosed rocks in the granulite facies. This suggests the possibility of finding unique and valuable materials. The area's geology is particularly well-suited for research aimed at block extraction ECONOMICAL FEASIBILITY The methodology used in the study was thorough, involving multiple stages including data acquisition and analysis, field surveys, interpretation, and report preparation. Field activities allowed for the identification of a single main geological compartment within the visited process, allowing for the cataloging of several outcrops. HIGH MINERAL POTENTIAL The area has mineral potential, specifically for metallic associations and ornamental stone. Although the volume of the sheared and sulfide-rich layer may not be very significant for metallic associations, the possibility exists. The rock's color and the existence of a nearby quarry of similar material also suggest potential for ornamental stone extraction Tune in to our exclusive podcast showcasing the Granite deposit in Floresta Azul, Bahia. Deep Dive BRM Podcast 00:00 / 08:10 LOCATION AND LOGISTICS The area of mining process No. 870.935/2021 covers 41.01 hectares and is located in the municipality of Itaju do Colônia, Bahia, near the municipal headquarters. Fig 1 & 2. Geographical location of the visited mining process, highlighting access routes and other polygons of ANM processes. The nearest city is Floresta Azul-BA, which is 25 km away, with 12 km on well-maintained asphalt and 13 km on a dirt road, also in good condition. Floresta Azul is approximately 483 km from Salvador-BA. a) and b) illustrate the access routes to the visited area, on local dirt roads in good condition and with mountainous terrain. The region of Floresta Azul offers good infrastructure conditions to support a mining project. Although this city is inadequate in this regard, Ibicaraí is only 10 km away and Itabuna 48 km, both offering various options for hotels/inns, specialized workshops, heavy equipment rentals, and other positive aspects (such as banks and medical services). GEOLOGICAL CONTEXT AND REGIONAL MINERAL POTENTIAL The visited mining process is located in the southern part of the Itabuna-Salvador-Curaçá belt, where crystalline basement rocks such as various granulites predominate. The rocks of this macro-region correspond to a very ancient stage in the geological period and evolution of the deep continental crust along the southern/southeastern coast of Bahia. Two main types of granulites stand out near the visited area: Basic and Paraderived granulites. Basic granulites originate from highly metamorphosed metagabbros and metabasalts, usually occurring as deformed enclaves parallel to the regional foliation. They are generally composed of pyroxenes, opaque minerals, garnet, biotite, and quartz. Paraderived granulites , on the other hand, are also represented by enclaves but of larger proportions, reaching kilometers in size. These rocks exhibit greater compositional diversity, ranging from quartzites associated with iron/manganese formations, calc-silicate rocks, graphitic rocks, and other aluminum-magnesian granulites. This regional geological context limits the possibilities of various mineral substances with potential for investigation and/or exploitation. However, it increases the chances of identifying target zones for investigations of rock massifs suitable for ornamental stone extraction. It is important to highlight that the diversity of metamorphosed rocks in the granulite facies within this southern region of the Itabuna-Salvador-Curaçá belt creates opportunities to identify various different lithotypes within the evaluated area, which is under the influence of this context and has not undergone detailed specific mapping. Fig 5. Regional geology of the ANM process area in focus. Note that the predominant geological influence in the visited region is due to the presence of high-grade metamorphic rocks (granulites) that had different origins in their protoliths (such as volcanic rocks and sedimentary rocks). WORK METHODOLOGY The methodology applied in this work is divided into four stages: (1) acquisition, compilation, and analysis of pre-existing data; (2) field surveys; (3) interpretation of information and discussion; and (4) preparation of the report. The first stage consisted of collecting information on regional and local geology (focusing on the Itabuna-Salvador-Curaçá crystalline rock belt), where high-grade metamorphic rocks (granulites) occur, originating from a long tectonic evolution of various rock types. Various maps were developed after photointerpretation of satellite images and SRTM data from the Topodata project with 30m resolution. All maps were processed and georeferenced using ArcGIS 10.8 software. In the field, the surveys lasted 1 day and took place in October 2023. Outcrop points, control points, and an old deactivated quarry outside the mining process were visited. At each location with favorable physiographic characteristics, descriptions of local structural geology and strategic aspects were carried out, along with sample collection (when necessary). In the third stage, interpretations of field data, bibliography, and interpolations with maps were developed. Finally, all technical information was processed, interpreted, and discussed to support the preparation of this report and the standardization of the data. LOCAL GEOLOGY The field activities allowed for the identification of a single main geological compartment within the visited process, where minor variations in the observed rocks were noted but are not significant enough to be represented on the map. These variations appear to be associated with structures/deformation of the predominant lithotype in the polygon, which will be described below. TONALITIC GRANULITES. Several outcrops of the same type of crystalline rock from this geological unit were cataloged. It has a light to dark gray color with beige portions, a phaneritic texture with medium to fine grain size, and a typical composition of a metamorphosed tonalite, which is an igneous rock that, in this case, appears deformed and foliated along the NNW-SSE trend. The main outcrops observed are composed of pyroxene, biotite, quartz, garnet, and plagioclase. a), b), and c) illustrate the outcrop and details of the rock found to be the most representative of the evaluated area: a gray-colored granulite with varied hues and medium to coarse grain size. In this unit, as mentioned earlier, there are some changes in the compositional aspect of the lithotypes, which are associated with a more penetrative foliation and/or shear zones with a significant presence of iron oxides such as hematite. These are seen in considerable quantities, which clearly alter the rock's density, along with a finer grain size and the occurrence of sulfides (arsenopyrite or pyrite). Point 8 is an example where these more altered lithotypes are found. a) Outcrop with fold marks and penetrative foliation associated with a possible shear zone or high strain zone of the regional deformation; b) and c) illustrate in detail the characteristic of the rock, which contains a large amount of iron oxides and sulfides. Fig 5. Map of visited points, highlighting the deactivated quarry next to the visited ANM process. PREVIOUS MINERAL POTENTIAL OF THE AREA AND ROCK SAMPLING According to the preliminary data obtained and the macroscopic characteristics of the rocks described in this report, it is possible to state that the area has mineral potential, although not very high. In this sense, the following possibilities stand out: Metallic associations in rocks with sulfides and iron oxides, as the found characteristics are favorable for identifying metallic chemical elements. Despite this possibility, the apparent volume of the sheared and sulfide-rich layer is not very significant. Ornamental stone (block extraction) for two main aspects: the color of the rock and the existence of a quarry of the same material type just a few meters from the polygon. However, in these aspects, the following observations must be considered: The cited quarry is deactivated due to likely limited mining operations (highly fractured) for extracting blocks of adequate dimensions and/or market acceptance for the final product. The outcrops visited within the polygon of the dark-colored rock also show well-defined fracturing and foliation systems, characteristics that could hinder extraction, similar to the deactivated quarry mentioned. ROCK SAMPLING. During the field visit, samples were collected, subdivided according to the purpose of each one, based on the principle of a more detailed description in the office, with cataloging for laboratory submission and specific chemical tests, as well as polishing tests to verify the aesthetic quality of the existing dark granulite. GENERAL CONSIDERATIONS The previous chapters make it clear that there is a positive preliminary mineral potential for certain substances, thus, the scenarios highlighted below encompass research activities aimed at advancing work in both possibilities. METALLIC ASSOCIATIONS IN ROCKS WITH SULFIDES. Due to the geological possibilities of various metallic anomalies in this type of rock, the most appropriate course of action is to conduct preliminary chemical tests on the collected samples to then determine the viability of proceeding with new technical research stages. ORNAMENTAL STONE – DARK-COLORED GRANITES. To determine the feasibility of a block production project, it is essential to understand the quality of the final product and market acceptance, as well as the volume and actual fracture index of the potential mining fronts. FINAL CONCLUSIONS ABOUT THE GEOLOGY AND PREVIOUS MINERAL POTENTIAL, it is concluded that: The study area is located in a region with occurrences of intrusive igneous and metamorphic crystalline rocks, predominantly tonalites and related rocks, as well as sporadic occurrences of volcanic rocks associated with structures that may exhibit anomalous metal contents; Nonetheless, the geology of the area is more suited for research aimed solely at block extraction, which represents the greatest existing preliminary mineral potential; Key characteristics for proper mining operations still need further investigation in order to assess volume, quality, and isotropy of the rock, as suggested in above. ABOUT STRATEGIC POINTS, it is important to highlight that: The logistics for transporting a potential block extraction should be well planned, but initially, it presents good development conditions; It is essential that, before advancing with any research activity at any point within the areas, formal contact is made between the Holder and Surface Rights owner to clarify the research and mineral extraction intentions in the region; The area benefits from proximity to energy and water sources.
