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.
