Deep Dive BRM Podcast 00:00 / 08:51 LOCATION AND LOGISTICS The mining process area No. 870.959/2021 covers 65.4 hectares and is located in the municipality of Sento Sé/BA, near the border with Umburanas/BA. Figure 1 below illustrates the geographic location of the title. Fig 1 & 2. Geographical Location of the Visited ANM Process ACCESS ROUTES The access between the nearest city (Umburanas/BA) and the visited area is made via 52 km of dirt road, with structural conditions suitable for heavy vehicle traffic. a), b), and c) illustrate some points of access to the visited ANM process, a dirt road starting from Umburanas, BA. Highlight in c) is a truck transporting two quartzite blocks extracted from quarries neighboring the process. The gray quartzite deposit in focus is located approximately 550 km from Salvador/BA, while the distance to Cachoeiro de Itapemirim/ES is around 1,600 km. MUNICIPAL AND LOCAL INFRASTRUCTURE Nearest City (Umburanas): Umburanas has good infrastructure to support a mining project, as it offers various options for hotels/inns, workshops, heavy equipment rental, banks, gas stations, among others. The high activity of companies focused on the maintenance and installation of wind farms in the region contributes to these aspects. Nearest District (Campo Largo): The district of "Campo Largo," which belongs to Sento Sé, is the closest inhabited locality to the deposit in focus, located 2.6 km from the ANM process boundary. The presence of a perennial stream nearby allows easy access to water, as its collection would take place outside any potential Permanent Preservation Area (PPA) of the watercourse margin. Three-phase power is also nearby, approximately 470 meters in a straight line (from the power grid to the visited outcrops). Fig 3. Illustration of the positioning of the nearest power grid to the area, as well as the drainage systems that can provide a water supply for mining operations in the northwest quartzite sector of the ANM process. REGIONAL GEOLOGICAL CONTEXT The regional geology influencing the characteristics of the visited area is associated with the rocks of the northern sector of the Chapada Diamantina Group and the Morro do Chapéu Formation, featuring mountainous topography and terrain with altitudes above 1,000 meters. The predominant rocks in both groups include metaconglomerates, various types of metarenites, quartzites, metarhythmites, and other fine-grained rocks with low-grade metamorphism, schists, and other lithotypes associated with this type of polydeformed continental margin sedimentation environment. According to geological bibliographic maps, the Morro do Chapéu Formation is the most prominent in the context of these areas. The lithofacies association of the Morro do Chapéu Formation, based on descriptions from articles and academic studies conducted in Sento Sé and Umburanas, aligns closely with field observations. These include quartz-arenites, arkosic sandstones, and quartzites with plane-parallel and cross-bedding, as well as symmetrical and asymmetrical ripple marks. Figure 5 outlines the regional geological context in which the process is situated. Fig 5. Regional geology highlighting the distribution of the Chapada Diamantina Group and the Morro do Chapéu Formation, the main regional influences in the area. LOCAL GEOLOGY The mountainous formations that are highly prevalent in the region, associated with the northern sector of the Morro do Chapéu Formation, create a favorable environment for economic quartzite deposits of varying colors and styles. Active quarries extracting quartzite are located very close to the title in focus. Throughout the process area, gray quartzite outcrops predominate. These are well-crystallized, with minimal occurrence of superficial brittle structures (fractures and faults) and evidence of ductile deformation in the rock (caused by folding and shearing). Quartzite outcrops frequently exhibit primary sedimentary marks and structures, such as various types of stratifications. These structural characteristics of the massif, combined with the visual quality of the rocks, provide good potential for possible block extraction with economic viability. 1 Field activities included data collection from large outcrops and sampling of quartzites with a typically grayish coloration. 2 Field activities included data collection from large outcrops and sampling of quartzites with a typically grayish coloration. 1 Field activities included data collection from large outcrops and sampling of quartzites with a typically grayish coloration. 1/2 MINING HISTORY OF THE AREA Among the regional mineral potential for different substances, quartzites stand out the most. At a distance of 450 meters from the boundaries of the evaluated area, there are active quartzite mines, demonstrating the local potential for economic deposits of this type of material, as well as other quarries located slightly farther away but within the same geological context. Figure 7 below illustrates the location of the mentioned active quarry. Fig 7. Map showing the location of the quartzite mine in operation near the evaluated process. OBTAINED RESULTS METHODOLOGY OF THE EVALUATION CONDUCTED The methodology applied in this evaluation is divided into three stages: (1) evaluation of the set of procedural data from the ANM for the mining title; (2) field reconnaissance; and (3) data correlation and interpretation. The first stage consisted of verifying the procedural history of title 870.959/2021 at the ANM, where the events registered during the validity of the title were analyzed, as well as its current condition and phase, which, in this case, is regular and in the "Research Authorization" phase; The field reconnaissance lasted 2 days, during which several outcrops were visited to identify the lithostructural characteristics of the existing quartzite. During the visit, strategic information was also checked for the feasibility of a mining operation, such as distances and conditions of access routes, presence of water, energy, landowner interest, and volume/quality of the rocks; Technical and strategic interpretations regarding the obtained data were made to assess the feasibility of opening a quarry in the area, along with relevant recommendations. SURFACE QUALITY OF THE QUARTZITE As mentioned earlier, in the geological unit in focus, quartzite outcrops predominate, which can be either slightly or highly silicified, as well as metarenites, which are typically well recrystallized. What differentiates the isotropic quality in the rock matrix, according to field data, is the associated structure, as ductile deformation zones were observed in many "slab outcrops," indicating that there are areas with higher potential for certain types of blocks.

Magnesite from Brumado, Bahia — one of Brazil’s key regions for industrial minerals. BR Mining offers access to high-quality magnesite suitable for diverse applications. Magnesite Brumado - BA The area of mining process no. 870.963/2021 occupies 171.96ha and is located in the municipality of Brumado, Bahia, Brazil. HIGHLIGHTS RAIL LINES The VLI train line in Brumado, Bahia, plays a crucial role in the region's logistics and industrial operations, particularly supporting the transportation of minerals such as magnesite and other goods. VLI, a major logistics company in Brazil, integrates railways, ports, and terminals, optimizing the flow of raw materials and finished products across the country. GRADES Preliminary studies indicate that the MgO content in the region ranges between 90% and 94%, highlighting its exceptional quality. This high concentration underscores the region's potential and explains why major producers have chosen it as a hub for magnesite extraction since 1943. LOCATION The three largest companies involved in magnesite extraction in Bahia—IBAR Magnesite, RHI Magnesite, and IMI FABI—are strategically positioned near key mining region. IMI FABI stands out for its close proximity to mineral resources. This strategic clustering enhances logistical operations and supports the state’s prominence in the magnesite industry. GREEN BELT BRUMADO The GB Brumado represents the most prominent geological unit for a positive metallogenetic potential in the region. Below are the main lithotypes of the lower, middle, and upper sequences exposed in the Serra das Éguas, where the ANM process is located. Tune in to our exclusive podcast showcasing the Magnesite deposit in Brumado, Bahia. Deep Dive BRM Podcast 00:00 / 15:14 LOCATION AND LOGISTICS The mining process area No. 870.963/2021 covers 171.96 hectares and is located in the municipality of Brumado, Bahia. The access from the nearest city (Brumado) to the visited area is 13 km, via a well-maintained road comprising 4 km of asphalt and 9 km of well-maintained dirt road. It is important to note that the entire dirt road segment is maintained by the companies IMI FABI and RHI Magnesita, which produce talc and magnesite from mines located on the same mountain range as the ANM process area visited. Brumado is located approximately 540 km from the state capital, Salvador, Bahia. Fig 1. Local geology with rolling mesh and identified lithologies. Fig 1. Geographical Location of the Visited ANM Process Brumado offers excellent infrastructure in its urban center, providing robust support for mining projects of all sizes. The city features accommodations such as hotels and inns, workshops, restaurants, banks, quality medical services, and other relevant and positive aspects that make it well-suited for industrial and mining activities. GEOLOGICAL CONTEXT AND REGIONAL MINERAL POTENTIAL Regionally, the visited process is situated within a Granite-Greenstone geological context, specifically associated with the Brumado Greenstone Belt (GB Brumado), located in the southern sector of the Gavião Block, São Francisco Craton. The ANM process 870.963/2021 covers roughly 172 hectares over the Serra das Éguas, the main metavolcanic-sedimentary rock belt among the three subdivisions of the Brumado Greenstone Belt. This highlights an interesting preliminary potential due to the presence of large talc and magnesite deposits in the vicinity. Granite rocks and gneiss-migmatites are also found in the macro-region, though they have less relevance to the mineral potential of the visited area. Fig 2. Regional geology highlights the distribution of the Brumado Greenstone Belt and the gneiss-migmatites of the crystalline basement, which are the main regional influences in the area. As described, the Brumado Greenstone Belt represents the most significant geological unit for a positive metallogenic potential in the area. In this regard, the main lithotypes of the lower, middle, and upper sequences exposed in the Serra das Éguas, where the visited ANM process is located, are as follows. Lower Sequence: Ultramafic komatiitic flows, serpentized, tremolitized, and talcified, with narrow bands of BIF (banded iron formation), succeeded by mafic toleitic flows, amphibolitized, and horizons of calc-silicate rocks and felsic schists (bitotite and garnet). Middle Sequence: Felsic schists (metatuffs / metapelites / metavolcanics), cherts, and quartzites. Upper Sequence: A succession of metasediments represented by metacarbonates, quartzites, and BIFs. This sequence includes limestone, dolomite, and magnesite deposits. REGIONAL MINERAL OCCURENCES. Figure 3 below, illustrates the large number and frequency of talc and magnesite occurrences and deposits in the evaluated region, which have been cataloged by CBPM (Bahian Company of Mineral Research) and CPRM/SGB (Geological Service of Brazil). Other substances occur within the same geological context; however, they do not exhibit significant volume or quality like the aforementioned minerals. The operations of IMI FABI (talc extraction) and RHI Magnesita (magnesite extraction) in the same mountain range and geological context further confirm the presence of a highly positive regional mineral potential for the ANM process in question. Fig 3. Regional Mineral Occurrences Cataloged by CBPM and CPRM in the State of Bahia. Highlight to the very large volume of magnesite and talc concentrated in the study area, located to the west of Brumado (Serra das Éguas). In addition to the substances mentioned above, the field visit revealed evidence of rocks that may indicate potential interest in other occurrences in the area, such as quartzite and quartz, which will be discussed in the following chapter. Fig 4. Talc and magnesite mining operations are active in the macro-region of the visited area. Notably, all extractions occur within the same topography, known as Serra das Éguas. LOCAL GEOLOGY The field survey aimed to identify the most representative geological units on a regional scale but within the mining process area. Combined with pre-existing data, this allowed for the interpretation of the local mineral potential. In this context, 21 points were visited in the field, subdivided into "control" and "outcrop" categories. At these points, descriptions of the materials found, structural geology, interpretation of topography/relief/drainage, soil analysis, and sample collection were conducted. Fig 6. Map showing the locations of data collection points for geological reconnaissance. CRYSTALLINE BASEMENT ZONE – GNEISSES. Outcrops of rocks from this unit are frequent in the central sector of the visited process area, but they do not exhibit high mineral potential due to their compositional characteristics. These rocks are mostly stretched gneisses (with variations to augen gneisses) aligned along a local NNE/SSW trend ranging from N205° to N175°. They form structural contacts with other lithotypes of the metasedimentary unit of the Brumado Greenstone Belt, such as quartzites and calc-silicate rocks. The cataloged outcrops can essentially be described as: Crystalline rocks with high-grade penetrative foliation, composed of biotite, quartz, feldspars/plagioclase, and ferromagnesian minerals. They commonly feature quartz veins and narrow quartz stringers, particularly near contacts with adjacent units, indicating increased associated deformation. Fig 7. Examples of outcrops from the crystalline basement unit, central sector of the visited ANM process. METASEDIMENTS ZONE (BRUMADO GB) When interpreted alongside regional geological information, it is possible to infer that the field data represent all three stratigraphic sequences of the Brumado Greenstone Belt (lower, middle, and upper), as a wide variety of lithotypes were identified. This delineated unit presents the highest mineral potential in the area, justified by its metavolcano-sedimentary Greenstone nature (notably evidenced by metallic features observed in the field, such as the presence of manganese and iron metallic oxides) and metasedimentary rocks like well-recrystallized quartzites. Based on these observations, the main lithotypes identified during the geological reconnaissance are as follows: Calc-silicate rocks, characterized by a greenish color, very fine grain, and the presence of oxides in fracture planes. Foliated rock and quite representative within the unit. Quartzites and metarenites ranging from white to gray, with associated quartz veins and levels of chert present (likely between lithotype transition zones). BIFs (iron formations) present in a more localized manner, primarily consisting of metarenites/quartzites with thin laminations of hematite-rich layers. However, macroscopically, these rocks do not show significant potential for iron ore due to their volume/dimensions and modal composition with a high sterile/ore ratio. This unit is where the talc and magnesite extractions are located in the region, further demonstrating that these lithotype intercalations and their alterations provide greater mineral fertility within the Serra das Éguas. In the northeastern sector of the polygon, for example, points were visited that demonstrated high potential for magnesite. FINAL CONCLUSIONS ABOUT THE GEOLOGY AND IDENTIFIED MINERAL POTENTIAL, it can be concluded that: The region of the study area presents good mineral potential given the geological characteristics of the Brumado Greenstone Belt and Serra das Éguas.. The metasediment unit is the most promising, containing occurrences of metals, quartzites, and magnesite. ABOUT THE STRATEGIC POINTS, it is important to highlight that: The logistics for the potential extraction operation in the area are very favorable, given the existing infrastructure of roads, water, and energy, due to the active operations of the talc and magnesite mines nearby.

Discover high-grade Manganese from Campo Formoso, Bahia. BR Mining offers reliable sourcing and insights into one of Brazil’s key mineral regions. Manganese Campo Formoso - BA The area of mining process no. 870.997/2021 occupies 73.36ha and is located in the municipality of Campo Formoso, Bahia, Brazil. HIGHLIGHTS LOGISTICAL FRAMEWORK The location is suitable for water and energy supply, access, and transportation of ore, including the possibility of railway transport via the FCA – Ferrovia Centro Atlântica. If rail transport is not viable, highway transport to the nearest port is also plausible. The presence of the FCA railway is particularly valuable for large-scale manganese ore transport. GOLOGICAL CONTEXT Manganese concentrations in the region have a high frequency of other valuable metals associated with them such as iron and copper, and high-purity manganese is often found within high strain zones. The geological context and structures suggest a positive potential for other metallic elements like gold and chromium. LOCATION The region has excellent existing infrastructure to support the project. This includes well-maintained roads, hotels, specialized workshops, heavy equipment rentals, and other necessities such as banks and medical services HIGH MINERAL POTENTIAL There is a history of mining and prospecting of various substances including gold, quartz, gemstones, chromium, limestone, manganese, and quartzite in nearby locations. The Serra de Jacobina itself has significant metallogenetic potential, indicating diverse mineral substances may be found through more detailed research. Tune in to our exclusive podcast showcasing the Manganese & Quartzites deposit in Belmonte, Bahia. Deep Dive BRM Podcast 00:00 / 15:20 LOCATION AND LOGISTICS The area of mining process No. 870.997/2021 covers 76.36 hectares and is located in the municipality of Campo Formoso, Bahia, near the municipal headquarters. The nearest city is Campo Formoso itself, located 7 km away, with 5.5 km on well-maintained asphalt and 1.5 km on a dirt road, also in good condition. Campo Formoso is approximately 410 km away from Salvador, Bahia. Fig 1. Geographical Location of the Visited ANM Process Fig 1. Local geology with rolling mesh and identified lithologies. Fig 2. Map of main access routes to the visited site, highlighting the district of "Missão do Sahy," where the southern route begins (featuring gentler slopes in the mountainous terrain). The Campo Formoso region offers excellent infrastructure to support a mining project. In addition to the city having various options for hotels/guesthouses, specialized workshops, heavy equipment rental, and other positive aspects (such as banks and medical services), the neighboring city of Senhor do Bonfim is only 26 km away and also provides options to meet all the needs of a small-scale mining operation. Fig 3. The images illustrate the access routes to the visited area, consisting of dirt rural roads in good condition and mountainous terrain. GEOLOGICAL CONTEXT AND REGIONAL MINERAL POTENTIAL The visited mining site is located within the Contendas-Jacobina-Mirante Lineament, in the central part of the São Francisco Craton. The formation of this lineament, characterized by a mountainous relief extending 500 km in a NNE-SSW direction, is associated with the tectonic overlap of the Itabuna-Salvador-Curaçá Belt over the Jequié Block, both of which rest upon the Gavião Block. This geotectonic origin resulted in numerous deformational events that altered rocks, created geological structures, and enabled diverse mineral occurrences/deposits. This is the regional context of the so-called "Serra de Jacobina." As a result, the entire geographical terrain surrounding this mountainous zone exhibits favorable conditions for mineral fertility. Fig 4. Regional geology of the area under focus by the ANM process. Note that the predominant geological influence in the visited region is the Cruz das Almas Formation, which belongs to the Jacobina Group The main rocks present in the visited region that influence its geology are from the Cruz das Almas Formation (composed of metavillites, sandstones, quartzites, and schists) and the Missão do Sahy Formation (Metachert, manganiferous formation, BIFs, and phyllites). Mineral extraction is common in the region, with some cities having over 10 decades of activity in mining and prospecting, such as gold and quartz mining in Jacobina, gemstones in Pindobaçu, chromium and limestone in Campo Formoso, manganese in Senhor do Bonfim, and quartzite in Jaguarari. In this regard, the surroundings of the visited area are marked by a high mineral potential for various types of substances, as exemplified below, which are of great relevance for the technical observations that will be described in this report. Fig 5. Map of mineral occurrences, with a yellow highlight detailing the region of the visited area. REGIONAL OCCURRENCES OF MANGANESE. In the context of the Jacobina mountain range, which includes the surroundings of Campo Formoso and Senhor do Bonfim, the metallogenesis of manganese is similar: this substance was concentrated through hydrothermal processes along shearing structures, an origin that indicates characteristic for the quality of the ore in general: a high frequency of other metals associated with manganese, such as iron and copper. However, within high strain zones of the mineralized layer, it is usually possible to observe boudins with high-purity massive manganese. Fig 6. Example of a manganese mineralized zone in the region. In RED: Zone with Iron contamination. In BLUE: Zone rich in massive manganese. REGIONAL OCCURRENCES OF GOLD AND OTHER METALS. However, within high strain zones of the mineralized layer, it is usually possible to observe boudins with high-purity massive manganese. Some of the most famous metallic occurrences within the Serra de Jacobina are gold ore deposits, which are primarily more frequent from the city of Pindobaçu to the south of the mountain range (towards Miguel Calmon), where metaconglomerates and quartzites altered by hydrothermal activity host most of the gold mines and prospecting sites. The northern sector of the Serra de Jacobina, where the visited ANM process is located, near Campo Formoso, does not have a history of gold prospecting or extraction. However, the geological context and structures observed in the field suggest the possibility of positive anomalies, as the same geological processes of fluid alteration and element reconcentration occurred in the rocks present there. The existence of chromium deposits and copper occurrences less than 7 km away from the area, within the same geological context, also support the hypothesis of a positive regional potential for other metallic elements in the area. EXTRACTION OF QUARTZITES – QUARRIES IN OPERATION. In the last two decades, the Serra de Jacobina has been extensively explored for the extraction of ornamental stones, specifically quartzite. One of the most notable geological characteristics of the rocks in this mountain range is the concentration of Fuchsite in the quartzites and conglomerates of the Serra do Córrego, Rio do Ouro, and Cruz das Almas Formations, which gives the rocks a greenish color and adds greater value to the extracted material. The local topography allows for large volume deposits for quarry openings, and the center-north location in the state of Bahia favors the logistics of transporting these materials to other regions, such as Espírito Santo. The visited ANM process includes rocks of this nature, which may present feasibility for a quartzite extraction project. The cities of Jaguarari, Campo Formoso, Senhor do Bonfim, and Pindobaçu are examples of producers of blocks and are located near the evaluated region. LOCAL GEOLOGY The field activities allowed for the definition of 3 main geological compartments within the visited process, which are not defined here as Formations or individual units, but rather as zoning of distinct mineral potentials, making it easier to interpret and plan for the utilization of possible substances/ores in the area. ZONE OF MANGANESE-BEARING METASEDIMENTS. This zone covers the southern sector of the polygon and concentrates the main manganese occurrences in the area, with old prospecting sites and several outcrops enriched in the metal. As mentioned in the chapter above, the manganese concentrations in the Serra de Jacobina are associated with geological structures that altered the rocks and channeled fluids enriched with silica, manganese, iron, and other metals. The same typology was observed in the occurrences cataloged within the area: fine metasediments, such as phyllites and oxidized arkosic sandstones, sheared, with the presence of quartz veins/veinlets and many manganese and iron oxides precipitated in pockets and/or fracture planes within the rock, with pyrolusite and psilomelane being the main ore minerals present. In addition to this primary typology, there are also supergenic manganese concentrations above the enriched layers due to surface processes. This material, although of good concentration, has a smaller volume. The zone of manganese-bearing metasediments does not limit the occurrence of the metal to this region, but rather demonstrates the area within the polygon with the best characteristics of high strain shear zones containing manganese ore. It is in this zone that new exploratory studies regarding this ore should be focused. "Old excavation at point P26." "Old excavation at point P26."

This zone is bounded to the south by manganesiferous metasediments and to the north by crystalline basement rocks, thus occupying the entire central region of the mining process. The zone of metarenites and quartzites comprises a wide variety of siliciclastic rocks; however, ferruginous (oxidized) metarenites, white metarenites, and various quartzites (light-colored, greenish, and grayish) predominate. In addition to these rocks, large quartz veins are noticeable, along with fault systems, breccias, fractures, and shear zones, which may contain various mineralizations, such as manganese, gold, and other metals. Outcrop of dark gray quartzite at point P4 Outcrop of dark gray quartzite at point P4 Large white quartz vein identified near the ANM point at point P29 Large white quartz vein identified near the ANM point at point P29 Example of very fine-grained, heavily fractured oxidized metarenite at point P9 Example of very fine-grained, heavily fractured oxidized metarenite at point P9 Outcrop of dark gray quartzite at point P4 Outcrop of dark gray quartzite at point P4 1/3 The compartmentalization of this zone occurs along rock layers dipping steeply to the east, with layer orientation following the trend of the Serra de Jacobina, and foliation between N060° and N350°. Contact regions, where different lithotypes meet, are typically associated with structures that alter the chemical composition and physical characteristics of the rock. For this reason, in the northern contact zone with crystalline basement rocks, for example, alterations such as sericitization, kaolin formation, and other completely altered metasediments were observed. The zone of metarenites and quartzites thus presents a positive potential for: Identification of various metallic occurrences; Identification of quartz veins with high purity; Identification of rock masses for the extraction of quartzite blocks; Identification of other non-metallic substances associated with ductile and brittle geological structures. Fig 7. Outcrop of metasediments in a contact zone between geological units, with sheared, altered, and deformed rocks, including the presence of quartz veining and iron oxides—positive characteristics for identifying metals such as gold. Point P4. PREVIOUS MINERAL POTENTIAL AND EXTRACTION OF IDENTIFIED SUBSTANCES According to the preliminary data obtained, field data, and mining history information, it was possible to determine that the central and southern regions of the visited polygon are the ones of greatest interest in the short term for the advancement of various mineral exploration activities, as these areas host the main occurrences of manganese ore, quartzites, and other possible substances, as already described above. Based on this information, the following interpretations are made for each mineral possibility: MANGANESE ORE It presents positive and very promising mineral potential; however, some characteristics of the existing ore must be taken into consideration before determining the feasibility of its extraction, such as: Chemical quality of the ore: Although the samples appear to have few impurities, such as iron oxide and silica, the hydrothermal association of this metal leads to the possibility of contamination, as described in item 2.1. A more representative chemical characterization of the deposit is needed beyond the CHIP samples already collected in previous stages. Volume and waste/ore ratio: The mining process visited, in the southern sector, where the manganese ore occurs, is narrow, about 120m, which prevents other promising outcrops from being included in the reserve calculation for the deposit. In addition to this information, there is also the waste/ore ratio, which varies significantly at the visited points and may influence the calculation of the recoverable ore volume. In this regard, further research stages are required, which will be described and suggested. Fig 8. Example of a high-quality manganese ore sample obtained from the visited area, but still with the presence of impurities such as silica (yellowish colors). From a strategic perspective, the manganese ore is located in an area with favorable characteristics for water and energy supply, access, and ore transportation (including via railway, with the FCA – Ferrovia Centro Atlântica being present in Campo Formoso). Additionally, according to Mr. Jose Raimundo (guide during the field visit), the main surface owner is in agreement with the progression of research and extraction activities. QUARTZITE It shows positive potential due to the high likelihood of significant volume in different locations, as well as the surface characteristics of some outcrops found, such as point P30, which represents a micro-region with the presence of green quartzite (currently in high demand in the ornamental stone market). Despite these positive characteristics, when considering the idea of producing blocks from this material, it is necessary to take into account the constant presence of brittle structures (fractures and faults) that could compromise quarrying and the opening of pits, which were observed in many of the visited outcrops. Fig 9. Illustration of varied quartzite samples from different outcrops in the visited area. From a strategic perspective, access for production transportation, depending on the location within the area, would be via a secondary road to the south, through routes leading to the district of "Missão do Sahy," due to the steep slopes of the roads heading north toward Campo Formoso. Aside from this aspect, the area presents technical justifications for further development and investment in new research phases for this substance. OTHER METALS AND MINERAL SUBSTANCES As explained in the sections above, the local geological context allows for the possibility of mineralization of other metals in the rocks and geological structures. For example, samples were collected from a brecciated zone with manganese precipitation at point PXX, which, in addition to this material, includes evidence of hydrothermal activity—very promising characteristics for the identification of volatile elements, sulfides, and other base metals, for instance. Fig 10. It is possible to see in detail the angular fragments of white metarenite, quartz veins, and associated oxides. The Serra de Jacobina itself denotes significant metallogenetic potential, allowing for the identification of a wide variety of mineral substances in more detailed research stages. In the case of the area in focus, there is, for example, a possibility, albeit small, of quartz, gold, and chromium. ROCK SAMPLING During the field visit, 8 samples were collected, subdivided according to the objective of each, based on the principle of a more detailed description in the office, with cataloging for sending to the laboratory and specific chemical tests in the case of manganese ore and other specific rocks, as well as polishing tests to verify the aesthetic quality of the quartzites. GENERAL CONSIDERATIONS The previous chapters clearly indicate the existence of positive prior mineral potential for manganese ore and quartzite. Thus, the scenarios outlined below encompass research activities designed to advance work on both possibilities. MANGANESE ORE Due to the geological characteristics of the deposit type, as mentioned in item 6, it is recommended that complementary research stages be carried out for a more detailed assessment of volume, depth, surface occurrence, and mineral chemical quality. To achieve this, it is expected, in addition to a detailed mapping of the rocks and structures in the region, the development of sampling, and, at a minimum, geophysical acquisitions/modeling. ORNAMENTAL ROCK - QUARTZITES The sandstone and quartzite zone includes good occurrences and outcrops of quartzites with strong potential for advancing research, which should focus on the surface spatialization of the rocks and, mainly, on the structural characterization of the massifs. Detailed mapping should be used to identify the behaviors of the main fracture and fault families that could compromise the potential quarrying/extraction of blocks. OTHER OCCURRENCES Due to the positive potential of the region for the presence of various substances, a more detailed survey of the entire area is necessary, which will allow for the determination of the feasibility of advancing to more specific stages for other types of ore, such as those previously mentioned. FINAL CONCLUSIONS ABOUT THE GEOLOGY, it is concluded that: The study area is located in a region with occurrences of metasedimentary rocks and geological structures of high mineral potential from the Jacobina Group, predominantly consisting of quartzites, metarenites, and rocks altered by hydrothermalism. The geology of the area is favorable for the identification of different substances and ores. ABOUT THE CURRENT MINERAL POTENTIAL, it is concluded that: With the reconnaissance data, it was possible to define 3 zones of distinct mineral potentials, with the southern sector being of the greatest interest due to the large occurrences of manganese ore. The other two zones are secondary in terms of mineral potential, but they may still indicate the existence of economically viable substances (such as quartzites). Despite being promising, especially for manganese, the real mineral potential of the visited ANM process will be defined after the advancement of the activities proposed in Tables 3, 4, and 5, and the results presented, where the best strategy for continuity, production, or interruption of the projects will be determined. ABOUT THE STRATEGIC POINTS, it is important to highlight that: The logistics for the transportation of a possible block and/or gold extraction should be well planned, but initially, it presents good development conditions. The presence of FCA – Ferrovia Centro Atlântica Railway, 8 km away, facilitates the design of a large-scale transportation logistics for manganese ore. However, if this is not a viable option, transportation by highways to the nearest port (Aratu – 390 km) is also plausible. The area is close to a power source, while water should be sourced from the surrounding areas, without major difficulties.

Explore premium Limestone and Marble from Itapebí, Bahia. BR Mining connects you to high-quality Brazilian natural stone, ideal for construction and design projects. Limestone & Marble Itapebí - BA The area of mining process no. 872.297/2021 occupies 557,15ha and is located in the municipality of Sento Sé, Bahia, Brazil. HIGHLIGHTS LOCATION The area is located within a region known for its mineral potential. The report notes that the macro-region of the referenced mining area contains various active mineral extraction sites for marble and limestone, suggesting a minimum geological potential nearby. This region is part of the "Araçuaí Belt," which is known for its complex tectonic structures formed during the Neoproterozoic era. Additionally, the specific area of the mining process is within the Rio Pardo Group, which is favorable to the presence of carbonate and quartzitic rocks GOLOGICAL CONTEXT The eastern sector of the area shows promising signs for mineral exploration. The report specifies that the eastern sector has a substantially greater number of outcrops, which allowed for the interpretation of varied metasediments, quartz veins, and varying degrees of metamorphism. The rocks identified in this sector could potentially be sources for dolomitic or calcite limestone and high-purity quartz ECONOMICAL FEASIBILITY The presence of high-purity quartz veins is a significant positive finding. The report indicates that veins of high-purity quartz were observed in various points in the eastern sector, and that some of these veins show high purity due to their crystallinity and color. The report also notes that point P17 illustrates a high silica content. The report also states that these veins are common near metarenite occurrences HIGH MINERAL POTENTIAL There is preliminary mineral potential for both limestone and quartz, making further research worthwhile. The report concludes that there is a positive preliminary mineral potential for limestone and quartz. The report recommends conducting preliminary chemical tests on the collected samples of limestone to determine the viability of further technical research. It also recommends a more detailed assessment of the quartz occurrences to understand the feasibility of a mineral production project Tune in to our exclusive podcast showcasing the Limestone & Marble deposit in Itapebí, Bahia. Deep Dive BRM Podcast 00:00 / 12:21 GEOLOGICAL CONTEXT AND REGIONAL MINERAL POTENTIAL The visited mining area is part of the regional context of the "Araçuaí Belt," a Brasiliano fold belt that borders the São Francisco Craton through large zones of complex tectonic structures formed during its Neoproterozoic evolution. The Araçuaí Belt is extensive and covers a significant portion of southeastern Bahia and northeastern Minas Gerais. The visited area, more specifically, is located within the Rio Pardo Group, in a region close to the contacts between crystalline basement rocks and more recent sedimentary cover rocks. RIO DO PARDO GROUP. The Rio Pardo Group comprises metasedimentary rocks formed in continental, restricted marine, and open marine depositional environments. Within the group, there are two sub-basins: a northern one and a southern one, with the latter being of greater interest in this evaluation. The southern sub-basin of the Rio Pardo Group consists of three distinct rock formations: the Panelinha Formation, Serra do Paraíso Formation (where the evaluated area is located), Água Preta Formation, and Camacan Formation. Of all the formations mentioned, the Serra do Paraíso Formation is the most recent, having been the last to be deposited in the sedimentary basin of origin. It is composed mainly of various types of carbonates (with varying degrees of metamorphism) and quartzites, precisely as observed during the field visit for the area’s assessment. Fig 2. Regional geology of the area of the ANM process in focus. Note that the entire polygon is under the influence of the Serra do Paraíso Formation, composed of carbonates and quartzites. REGIONAL POTENTIAL FOR CARBONATE PRODUCTS. As mentioned in the "Rio do Pardo Group" section, the area has a regional context favorable to the presence of carbonate and quartzitic rocks, with the former being major sources of marble or limestone occurrences, for example. The macro-region of the referenced ANM process contains various active mineral extraction sites for marble and limestone, which already suggests some minimum geological potential nearby. Figure 3 below illustrates the location of the mining operations within the region of polygon 872.297/2021. Fig 3. Active ANM processes under mining application or concession, highlighting three operations that produce marble and limestone very close to the evaluated ANM process. WORK METHODOLOGY The methodology applied in this work is divided into four stages: (1) data acquisition, compilation, and analysis of existing data; (2) field surveys; (3) interpretation of information and discussion; and (4) report preparation. The first stage consisted of gathering information on the regional and local geology (focusing on the Rio Pardo Group and Serra do Paraíso Formation, which are part of the regional context of the Araçuaí Belt), where metasedimentary rocks are found, associated with basin closure structure and rock deformation/metamorphism; Various maps were developed after the photointerpretation of satellite images and SRTM data from the Topodata project with 30m resolution. All maps were processed and georeferenced in ArcGIS 10.8 software. The field surveys lasted 2 days and took place in October 2023. Outcrops and control points within and outside the mining process were visited. In each location with favorable physiographic features, descriptions of local structural geology and strategic aspects were made, along with sample collection (when necessary); In the third stage, interpretations of field data, bibliography, and interpolation 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 identification of the predominant rocks in the ANM process was made easier after subdividing the area into two sectors: West and East. This was due to the distinct differences in relief, soil, and land use, as well as the mineral potential of each, which shows varying levels. Therefore, the local geology will be described considering the two polygons, which can be more clearly seen in Figure 5. Fig 5. Map of the location of the subdivided sectors in the visited ANM process. GEOLOGY OF THE WEST SECTOR. Considering the west and east sectors, the geology of the visited ANM process can be characterized as a single unit, where the lithotypes vary according to their mineral composition but maintain the same metasedimentary origin. However, the major difference between the sectors outlined here is the degree of exposure of the outcropping rocks, as in the west sector, there are virtually no exposed rocks due to the topography and large eucalyptus plantations of Veracel Celulose. Points P12 and P14 were the only ones that allowed for the observation of rock within the survey conducted in this west sector, and they showed that the rocks present are basically: Foliated limestones, gray in color with very fine granularity, making it difficult to define their degree of purity, but apparently showing to be impure limestone with the presence of silica. Samples showed little reaction to hydrochloric acid, making it an inconclusive test for interpreting its composition. Iron-rich concretions in lateritic rocks, with iron oxides present, giving cohesion to the brownish-colored sand-silt matrix. Fragments of angular quartz are also common, likely originating from superficial fragments of quartz veins in the region. a) Outcrop of impure limestone at point P12, and b) Large boulder on the side of a hill with lateritic concretion, point P14. Correlation of map data and bibliography with field observations allowed us to infer that the geological pattern below the surface/soil in the west sector remains similar, even without many directly observed data. GEOLOGY OF THE EAST SECTOR. Unlike the previous sector, the eastern region of the visited ANM process is characterized by land use focused solely on livestock farming, with a landscape of extensive pastures, hills, and valleys (Figure 3). Fig 3. Overview of the physiographic aspects of the terrain in the East sector, viewed towards N200° from point P28. The physiographic characteristics of this sector allowed for the identification of a substantially greater number of outcrops, from which it was possible to interpret that they are rocks from the same micro-regional context, with varied metasediments, quartz veins, and varying degrees of metamorphism. In this regard, it is worth highlighting: Limestones: similar to those described in the west sector; however, they occur here with a greater variation in purity, tending towards calcarenite with fine granularity. a) and b) illustrate outcrops of impure limestone tending towards calcarenite, light in color and heavily fractured. Point P15. Metarenites: they occur friable and weathered, but certainly contribute a large volume to the metasediment package in the area, being in gradual contact with the limestone layers. They are light-colored (white to beige), with fine granularity and a composition mainly composed of sub-rounded quartz grains. a) and b) illustrate outcrops of friable metarenite at point P16. Quartz veins: these are common near the occurrences of metarenites, which are likely correlated. These veins were observed in outcrops up to 2 meters thick and/or boulders of small and large dimensions at various points. The physical characteristics of the material stand out here, showing a high degree of purity due to its crystallinity and white/transparent color. a) and b) illustrate outcrops of quartz veins, common in the eastern sector of the visited process. Points P13. PREVIOUS MINERAL POTENTIAL OF THE AREA AND ROCK SAMPLING Based on the data obtained, field data, literature, and mining history, it was possible to define that only the Eastern sector of the visited process deserves attention regarding the advancement of exploratory research. The rocks identified in this sector and described in item 5.2 can be a mineral source for the substances: dolomitic limestone or calcite limestone and high-purity quartz, and based on these informations, the following interpretations are made for each possibility: CALCIUM CARBONATE OR DOLOMITE AND MARBLE. The presence of carbonate rocks in the area allows for the possibility of anomalous levels of magnesium and/or calcium, giving rise to calcium carbonate minerals for soil correction and still zones of greater degree of metamorphism that allow for the formation of massive marble deposits. The occurrence of these rocks in various points also allows for the interpretation that there may be volumes beneath the surface that could enable some type of production, however, this type of mining tends to be more profitable and less costly when of the positive type, and the terrain of the eastern sector tends to provide a negative front. Another factor of great relevance for evaluating the viability of this type of undertaking is the logistics and local market, which in this case, does not show a very favorable disposition due to the poor conditions of access, a distance superior to 7km to asphalt and proximity of large quarries in operation, which present better logistics and excellent deposits for extraction/production of the mine. Finally, it is primordial to understand the chemical characteristics of the samples/rocks collected, these results are what can define the path to be followed in the course of a possible mining project of calcium carbonate. HIGH-PURITY QUARTZ. Veins of high-purity quartz were visualized in various points of the eastern sector of the ANM process visited, and in some of them it was possible to observe macroscopically a high purity, given the crystallinity and coloration of the material. For example, point P13 illustrates a vein of large proportions found, while point P17 illustrates the chemical quality of the rock, which appears to have a high silica content (see Figure 6 ). Preliminary information is not sufficient to understand the potential volume of these veins, however, the analysis and chemical characterization of these veins is fundamental for determining whether to advance or not with the idea of more detailed research on this substance. ROCK SAMPLING. During the field visit, 8 samples were collected and subdivided according to the purpose of each one, based on the principle of providing a more detailed description in the office, with cataloging for laboratory submission and specific chemical tests for limestone and quartz. GENERAL CONSIDERATIONS The previous chapters make it clear that there is a positive preliminary mineral potential for limestone and quartz. Therefore, the scenarios outlined below encompass research activities designed to advance work on both possibilities. LIMESTONE. 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. QUARTZ. As outlined in the items above, the quartz occurrences in the eastern sector deserve attention from the perspective of a more detailed assessment of their potential, as the initial visit already indicated its presence in different areas, all with good physical characteristics. Based on these observations, target definition will be essential to understand the feasibility of considering a mineral production project involving this substance. FINAL CONCLUSIONS ON THE GEOLOGY, it is concluded that: The study area is located in a region with limited geological variety, predominantly featuring metamorphosed metasediments of varying degrees, resulting in formations such as limestones, metarenites, and associated quartz veins; The eastern sector of the ANM process visited is the one that provides the most geological information regarding its mineral potential and possible product types. ON THE CURRENT MINERAL POTENTIAL, it is noted that: Based on reconnaissance data, only two types of substances have been identified as having potential economic value, depending on laboratory results: high-purity quartz and limestone; Despite its promise, the actual mineral potential of the visited ANM process will be determined after further research activities and the presentation of results, at which point the best strategy for continuation, production, or discontinuation of the projects will be defined. ON STRATEGIC POINTS, it is important to highlight that: The logistics of transporting potential limestone extraction should be carefully planned due to the distance from the asphalt and the quality of the existing access routes; There is a large quarry in operation near the area, managed by the company "Calcário BR-101," which operates approximately 2 km from the asphalt with productive and high-volume mining fronts. This could impact market competition for any potential product to be mined in the visited area; It is essential that, before proceeding with any research activities in any part of the areas, a formal agreement between the Titleholder and Surface Owners be established to clarify the intentions regarding mineral research and extraction in the region, considering the promising initial contact with the field team; The area has access to nearby energy sources, while water will likely need to be sourced locally, probably through tubular wells.
