S-K 1300 Technical Report – Iporá REE Project – Goiás State, Brazil | Page 6 |
1.4 | Geology and Mineralization |
From a regional perspective, the Iporá project is located south of the Southern Amazon Craton, west of the São Francisco Craton and sits near the contact between the Paraná Basin and the Brasiliano (or Brasília) Fold Belt (BFB).
Specifically, the project is located within the Tocantins Structural Province in the BFB, which is part of the Goiás Magmatic Arc and it lies approximately at the center of the BFB on the western margin of the belt.
The representative of Goiás Magmatic Arc in the region is the Neopreoterzoic Iporá Granite, composed of granites, granodiorites and quartz monzonites. These rocks are mainly formed by large microcline crystals (~5cm), quartz and amphibole as the main mafic phase, which occurs associated with biotite as hypidiomorphic crystal aggregated. The accessory phase is composed of zircon, sphene, apatite, allanite and other opaque minerals. This unit has calcalkaline affinity and are correlated to the batholiths of juvenile magmatic arc (Pimentel & Fuck, 1987a).
The North border of the Paraná Basin, in Central Brazil, is characterized by an erosive scenario very active during the Upper Cretaceous with the intrusion of alkaline magmatism in the region. This magmatism is represented by two main provinces: Goiás Alkaline Province and Alto Paranaíba Igneous Province. It is set in groups of intrusions in Goiás and Minas Gerais states, disposed in linear arrangements parallel (Az 125º), some hundreds of kilometers apart (Dutra et al., 2012). The Iporá project is situated within the Goiás Alkaline Province.
The Goiás Alkaline Province (GAP) is a late cretaceous alkaline igneous province, stretching 250km in a NW-SE direction and up to 70 km wide. It includes mafic-ultramafic complexes in the northern portion, subvolcanic intrusions in the central region and volcanic products south, with several dikes (Junqueira-Brod et al., 2005).
The Córrego dos Bois alkaline complex covers an area of approximately 33 km² and corresponds to the largest of the northern GAP complexes. (Dutra et al., 2012).
The Córrego dos Bois Complex is formed by central zoned intrusions with magmatic differentiation of the central dunite – periodotite – pyroxenite – alkaline gabbro – nepheline syenite for the first magmatic event, between 75 and 81 Ma (Danni 1974). The second magmatic event is characterized by subvolcanic intrusions, as lamprophyres, nefelinites and analcimites in soles and dikes, around 60 Ma. The rocks are described as dunites, wehrlites, olivine-pyroxenites and websterites. Besides the main mafic components of these rocks, as olivine, plagioclase, augite, the secondary components are zeolites, biotite and opaque minerals.
Mapping by Atlas on the Iporá tenements has identified five major lithographic units. These units are:
● | Ribeirão de Santo Antonio Metagranite | |
● | Iporá Granite | |
● | Paraná Basin sedimentary rocks | |
● | Alkaline units of the Goiás Alkaline Complex | |
● | Laterites |
The Ribeirão Santo Antônio metagranite occurs in the east portion of tenement 860.438/2022, at elevations above 600m, outcropping predominantly as blocks. The rock is composed of plagioclase, k-feldspar, quartz and biotite and displays a granolepdoblastic texture with foliation defined by biotite (Figure 6-4). Additionally, plagioclase augen porphyroclasts may be present.
The representative of Goiás Magmatic Arc in the region is the Neopreoterzoic Iporá Granite. The Iporá Granite rocks correspond to an undeformed syeno-granite, with isotropic coarse texture (Figure 6-5) composed of euhedral alkali-feldspar and granular quartz (>20% of the rock), and very few mafic phases, a very fine aggregate, probably composed of allanite, biotite and oxides. The outcrops are in the form of boulders ranging from a meter to tens of meters in size.
S-K 1300 Technical Report – Iporá REE Project – Goiás State, Brazil | Page 7 |
The Paraná Basin sediments comprise sandstones and conglomerates from the Furnas and Ponta Grossa formations. These quartz-rich siliciclastic formations belong to an extensive, neo-ordovician to late cretaceous South American intracratonic basin, developed over a continental crust and filled by sedimentary and volcanic rocks. The sandstones are well selected, reddish to white and cemented by silica and Fe hydroxides, and the conglomerate is composed of quartz pebbles and granules with matrix of fine quartz and mica sand and kaolinite.
At the Paraná Basin’s edges, late Cretaceous alkaline magmatism took place and formed large intrusive complexes with a wide range of rock compositions. The Córrego dos Bois Complex is one of eleven mapped alkaline complexes within the GAP and is the main alkaline complex of the Iporá project. Within the project area, mapped lithotypes related to the Córrego dos Bois Complex are syenite, ultramafic (peridotite and pyroxenite) and mafic (gabbro) rocks and trachyte.
The syenite is composed mainly of alkali feldspar and mafic minerals, pyroxenes and amphibole, with little altered nepheline relicts. Mafic rocks include gabbro and subvolcanic products, composed of plagioclase, pyroxene and small (<5mm) phlogopite crystals. The ultramafic rocks are represented in the area by a peridotite, composed of fine olivine and pyroxene crystals. The trachytes are a subvolcanic product of syenites, with feldspar phenocrysts embedded in a grey, volcanic matrix.
Rocks of Córrego dos Bois Complex tend to define the geomorphological setting of the region, preserving steep hills with dense, natural vegetation. It is possible to distinguish a different type of laterite generated by this unit, a muddy, silky and purple-reddish laterite with distinct characteristics.
The laterites are divided into two lithotypes: duricrust (Figure 6-8) and latosol soil. Observations about the laterites included grain size, color, composition of grains and cement, cement proportion, structures such as mottles, pores, presence of pisolites and oolites and transport.
A red latosol soil with little or no quartz, kaolinitic and micaceous composition is predominant in the area, and the presence of talc was noticed, indicating the ultramafic rocks as the parental rock. Some of the red latosol presents kaolinitic composition, with low quartz e sometimes shows fragments of saprolite granites, suggesting the Iporá Granite as parental rock.
The duricrusts also vary according to its source. Pale beige duricrusts are associated with Paraná Basin rocks, whereas red, purple, pisoolitic and ferriferous duricrusts are related to igneous, especially ultramafic rocks. Sometimes the duricrusts have a transported aspect, but most times they appear as an in-situ unit.
The geological setting of the Iporá Project is typical of a regolith-hosted REE deposit (ion-adsorption REE deposits or ionic clay), which combines type-A alkaline granites with supergene enrichment, with the southern China deposits being the type example.
1.5 | Exploration and Drilling |
Atlas carried out exploration during June and July 2025 on tenements 860.440/2022, 860.438/2022, 860.439/2022 and 860.667/2023. The exploration consisted of surface mapping, surface sampling and an auger sampling program.
Atlas mapped the above-mentioned tenements at a scale of 1:12.500. The majority of the tenements have extensive lateritic overburden, but geology was inferred from surface outcrops.
Atlas collected a total of 161 samples across the four tenements and the five major lithotypes identified on the property. The goal was to try and establish a correlation between lateritic bodies and possible sources of REE.
S-K 1300 Technical Report – Iporá REE Project – Goiás State, Brazil | Page 8 |
Atlas conducted an auger drilling campaign over the four tenements, completing 18 drillholes for 170.68 m of drilling. The average depth of the auger holes was 9.48 m.
The results indicate a large, approximately 10 m thick, near-surface mineralized horizon.
1.6 | Sample Preparation, Analyses, Security |
In 2025, Atlas Critical Minerals have done a range of sampling and assaying including surface samples and auger samples. Atlas Critical Minerals has utilized Quality Assurance (QA) and Quality Control (QC) methodologies under the supervision of a qualified person as defined in Regulation S-K 1300.
Atlas supplied the final database on September 23, 2025.
A total of 18 blanks were analyzed. The analysis returned acceptable values within 10 times the detection limit for Dy and Tb. Possible discrepancies were observed with Nd, Pr, La, and Ce.
A total of 18 standards were analyzed, only two results, Nd and Tb OREAS_461 samples returned values outside of three standard deviations. For the purpose of this report, SGS consider the samples to be acceptable.
1.7 | Data Verification |
No property inspection has been completed at this time.
1.8 | Mineral Resource Estimates |
There are no Mineral Resource Estimates on this Project.
1.9 | Adjacent Properties |
Atlas Critical Minerals mineral rights are located near to or adjacent to tenements held by Appia Rare Earths & Uranium Corp. (“Appia”) and Companhia Níquel Santa Fé (“Santa Fé).
Appia has a published mineral resource estimate (MRE) for REEs for the PHC Ionic Clay Project, and Santa Fé has 10 permits for the exploration and mining of nickel and cobalt ore.
1.10 | Conclusions and Recommendations |
1.10.1 | Conclusions |
Atlas has 12 exploration tenements to the east and north of the city of Iporá, in Goiás state in Brazil. Of the 12 tenements, Atlas focused on the exploration of four tenements immediately adjacent to Appia’s PCH ionic clay deposit, north of Iporá.
Atlas conducted surface mapping, surface sampling and auger sampling on tenements 860.440/2022, 860.438/2022, 860.439/2022 and 860.667/2023 during June and July 2025.
The results of the exploration suggest that the four mining rights of the Iporá Project present favorable conditions for ionic clay deposits. Regolith horizons were mapped in the four mining rights, as well as laterite layers associated with alkaline and Cambrian granite rocks. These laterites have grades compatible with ion-adsorption REE deposit type, from 900 to 1500 ppm TREO, as evidenced by both surface and auger samples.
Based on the exploration results, the central-eastern regions of mining right 860.440/2022 and the western regions of 860.438/2022 comprise the most favorable area for a regolith-hosted REE target, comprising a laterite associated with alkaline rocks of the GAP with an area of approximately 8 km² and two other smaller laterites bodies, reaching up to 4 km², superimposed on the Iporá Granite.
The initial metallurgical test work indicated that TREO recoveries of 36% and HREO recoveries up to 55% were possible.
1.10.2 | Recommendations |
Given the prospective nature of the Iporá Project, it is QP’s opinion that the Project merits further exploration and that the proposed plan for further work by Atlas is justified. The proposed work program by Atlas will help advance the Project and will provide key inputs required to evaluate the economic viability of the Project.
The QP is recommending Atlas conduct further exploration, subject to funding and any other matters which may cause the proposed exploration program to be altered in the normal course of its business activities or alterations which may affect the program as a result of exploration activities themselves.

2.1.1 | Organization Structure of the Company |
Atlas Lithium Corp., a publicly traded company incorporated in the State of Nevada, United States, serves as the ultimate parent company of a group of corporate entities operating in both international and Brazilian jurisdictions. Through this structure, Atlas Lithium Corp. maintains direct or indirect ownership of several subsidiaries that carry out exploration and development activities in the mineral sector.
Internationally, notable subsidiaries include Atlas Lithium Limited and Brazil Mineral Resources Corporation, both incorporated in the Marshall Islands and wholly owned by Atlas Lithium Corp. The corporate group also includes Atlas Critical Minerals Corporation, in which Atlas Lithium Corp. holds a majority equity interest, and Athena Mineral Resources Corporation, likewise incorporated in the Marshall Islands and fully owned by the parent company.
In Brazil, the principal direct subsidiary is Atlas Lítio Brasil Ltda., which is wholly owned by Atlas Lithium Corp. This entity serves as the main legal and operational interface of the parent company in Brazil but does not directly control or hold ownership stakes in other domestic subsidiaries within the group.
S-K 1300 Technical Report – Iporá REE Project – Goiás State, Brazil | Page 10 |
Atlas Recursos Minerais Ltda. is a Brazilian entity indirectly held by Atlas Lithium Corp. through Brazil Mineral Resources Corporation, its immediate parent company. Given that Brazil Mineral Resources Corporation is wholly owned by Atlas Lithium Corp., Atlas Recursos Minerais is considered a second-tier subsidiary within the group. It operates independently from Atlas Lítio Brasil Ltda., and no direct corporate relationship exists between the two, notwithstanding their shared ultimate ownership.
Atlas Critical Minerals Corporation represents a separate branch of the corporate structure and conducts its Brazilian operations through majority ownership of several local entities. These include Mineração Apollo Ltda., which holds controlling interests in RST Recursos Minerais Ltda. and Mineração Duas Barras Ltda. In addition, Mineração Júpiter Ltda. is also under the direct control of Atlas Critical Minerals Corporation. In all these cases, a minority equity stake (0.01%) is held by Lancaster Invest. Ltda., a Brazilian company primarily owned by Marc Fogassa, who holds a 99.9% ownership interest. Mr. Fogassa currently serves as Chairman and Chief Executive Officer of both Atlas Lithium Corp. and Atlas Critical Minerals Corporation, underscoring his key role in the strategic oversight of the group.

3.1 | Property Description and Location |
The Iporá Project is located in the western region of Goiás state, Brazil, about 289 km from Goiânia, around the municipalities of Iporá, Diorama and Montes Claros de Goiás. The Iporá Project is located at approximately 51º13’43’’ latitude and 16º14’53’’ longitude, Universal Transverse Mercator (UTM) zone 22S, coordinates of 475,563 m E and 8,203,577 m N.
Figure 3-1 shows the location of the Iporá Project.
Figure 3-1: Location of the Iporá Project
S-K 1300 Technical Report – Iporá REE Project – Goiás State, Brazil | Page 13 |
3.2 | Mineral Tenure |
The legal framework for the development and use of mineral resources in Brazil was established by the Brazilian Federal Constitution, which was enacted on October 5, 1988 (the Brazilian Constitution) and the Brazilian mining code, which was enacted on January 29, 1940 (Decree-Law 1985/40, later modified by Decree-Law 227, of February 28, 1967, the Brazilian Mining Code).
According to the Brazilian Constitution, all mineral resources in Brazil are the property of the Federal Government. The Brazilian Constitution also guarantees mining companies the full property of the mineral products that are mined under their respective concessions. Mineral rights come under the jurisdiction of the Federal Government and mining legislation is enacted at the Federal level only. To apply for and acquire mineral rights, a company must be incorporated under Brazilian law, have its management domiciled within Brazil, and its head office and administration in Brazil.
In general, there are no restrictions on foreign investment in the Brazilian mining industry, except for mining companies that operate, or hold mineral rights within a 150 km wide strip of land parallel to the Brazilian terrestrial borders. In this instance the equity interests of such companies have to be majority Brazilian-owned. Exploration and mining activities in the border zone are regulated by the Brazilian Mining Code and supporting legislation.
The Iporá Project comprises 12 mineral rights under exploration permit status in National Mining Agency (ANM), covering an area of 18,615 ha (46,000 acres). Figure 3-2 shows the location of the mineral rights in relation to the municipalities of Iporá, Diorama and Montes Claros de Goiás. In addition, the tenure holdings are summarized in Table 3-2.

Under Brazilian law, foreign companies may acquire surface rights as long as the share capital is controlled by Brazilians. However, the holder of an exploration license is guaranteed by law access to be able to conduct exploration field work, provided that adequate compensation is paid to third-party landowners, and that the holder of the exploration license assumes all environmental responsibilities arising from the exploration work.
After the exploration license is granted by the Brazilian government, Atlas negotiates and obtains the necessary authorizations for access to the properties for research and exploration activities, with the exercise of mining activity guaranteed by the Brazilian Federal Constitution.
Atlas is responsible for the reclamation of areas used for drilling, safety of personnel in the work area, monetary compensation to the landowner for surface damage caused by mineral exploration activities, and all environmental liabilities resultant from exploration activities.
3.3 | Royalties and Encumbrances |
On December 18, 2024, Atlas Critical Minerals Corporation (“Atlas Critical Minerals”) entered into an Option Agreement (“Option”) with Atlas Lithium Corporation (“Atlas Lithium”), pursuant to which Atlas Critical Minerals purchased an option to acquire 100% of Brazil Minerals Resources Corporation (“BMR”), a subsidiary of Atlas Lithium. BMR owns 100% of Atlas Recursos Minerais Ltda which holds certain mineral rights in Brazil which are of interest to Atlas Critical Minerals. The Option therefore grants Atlas Critical Minerals the opportunity to have ownership of such mineral rights in the future, should it choose to exercise the Option.
3.4 | Reliance on Other Experts |
The QP has not reviewed the mineral tenure, nor independently verified the legal status, ownership of the Project area, underlying property agreements or permits. The QP has fully relied upon, and disclaims responsibility for, information supplied to them by Atlas Critical Minerals.

4 | ACCESSIBILITY, CLIMATE, LOCAL RESOURCES, INFRASTRUCTURE, AND PHYSIOGRAPHY |
4.1 | Accessibility |
The Iporá Project is located in the western region of Goiás state, Brazil, about 289 km from Goiânia, around the municipalities of Iporá, Diorama and Montes Claros de Goiás. Access from Goiânia is reached by highway GO-060 for 225 km to the city of Iporá, followed by GO-174 for 31 km to Diorama and another 33 km to Montes Claros de Goiás (Figure 4-1).
The Project comprises 12 mineral rights permits, totaling 18,615 ha distributed around the cities of Iporá, Diorama and Montes Claros de Goiás cities The shortest distance between the mineral rights permits and theses cities varies of 2,3 km (Iporá), 700 m (Diorama), and 1,35 km (Montes Claros de Goiás).
The access is through a well-developed network of regional roads. These roads offer a blend of hard and gravel surfaces, ensuring smooth and reliable transportation. Within the property boundaries, there exists a well-maintained network of gravel-surfaced rural roads and unsurfaced farm roads that provide project accessibility.
Figure 4-1: Location Map of the Iporá Project / State of Goiás
S-K 1300 Technical Report – Iporá REE Project – Goiás State, Brazil | Page 16 |
4.2 | Climate |
Iporá and the surrounding municipalities are part of the subhumid tropical climate, classified as Aw type (Köppen, 1948), characterized by a dry season from April to September and a rainy season from October to March. The average annual rainfall ranges from 1,500 to 1,700 mm (De Sousa & Rodrigues, 2018).
The region’s distance from the Atlantic Ocean results in high average temperatures with a high daily temperature range, and irregular rainfall patterns, as reported by De Sousa & Silva (2009).
The climate allows year-round access to the property and year-round exploration potential.
4.3 | Local Resources |
The project is located near the cities of Iporá (population: 31,499, according to a 2020 census), Diorama (population: 2,479 according to a 2020 census) and Montes Claros de Goiás (population: 8,047 according to a 2020 census).
The city of Iporá is situated 10 km from the Project, with an estimated population of 31,499 inhabitants (2020 Census). Electricity is provided by the concessionaire “Enel Distribuição Goiás”, in addition to the city offering other infrastructures, such as: Municipal airport, four hospitals, fire department, Civil and Military Policing, and Hotels and Restaurants.
The economic activities are mainly agriculture, services, light industry, and livestock raising.
Analytical and drilling services would be contracted in the metropolitan region of Belo Horizonte. Skilled and semi-skilled labor is available in the region to support exploration activities.
4.4 | Infrastructure |
The region hosts well-structured cities with robust capacities for electricity and water supply, all of which are easily accessible.
In addition to its strategic location, the presence of power and water adds to the project’s economic significance and underscores the potential for long-term resource extraction. The project is well-equipped to harness these resources while maintaining environmental responsibility and compliance with relevant regulations.
The nearest railway siding is located at Goiânia 216 km to the east of the project. This railway line leads north to the town of Palmas or south to São Paulo. Labour will be available from nearby regional towns and settlements. Potential tailings storage areas, waste disposal areas, heap leach pads, and potential processing plant sites can only be supplied after an Environmental Impact Assessment has been completed. Goiania should be able to supply most exploration requirements and comply with all sustenance supplies.
4.5 | Topography, Elevation and Vegetation |
The Iporá Project region is part of the Araguaia River basin, covering an area of 86,109 km2. The Araguaia River rises in the Caiapó hill, on the border between Goiás and Mato Grosso, at an altitude of 850 m, and flows for 2,115 km before discharging into the Tocantins River (De Sousa & Rodrigues, 2018).
The municipality of Iporá is drained by four sub-basins: the Santo Antônio and Lageado streams, which flows into the Caiapó River; the Santa Marta stream, which flows into Claro River and subsequently into the Araguaia River; and the Bois River basin, which drains directly into the Araguaia River (De Sousa & Rodrigues, 2018).
In general, the topography is controlled by the local geology and by the denudation of the South American Surface, with flat terrains prevailing in domains of gneissic rocks, as well as in volcano-sedimentary terrains and the edge of the Paraná Basin. The hills are associated with granitic intrusive bodies, cuestas formed by the erosional retreat of Paraná Basin sediments. Isolated elevations are found where igneous rocks of the Rio Verde-Iporá Alkaline Province occur (Moreton, 2001).
S-K 1300 Technical Report – Iporá REE Project – Goiás State, Brazil | Page 17 |
De Sousa & Rodrigues (2018) describe the municipality of Iporá as part to the regional geomorphological unit known as Northern Plateau of the Paraná Basin, which can be subdivided into 3 units:
● | Unit 1: Elevations ranging from 715 to 890 meters, characterized by sharp to convex hilltops resulting from residual reliefs developed on crystalline and alkaline rock structures | |
● | Unit 2: Elevations ranging from 550 to 714 meters, with convex hilltops formed mainly by granitic and gneissic basement rocks. | |
● | Unit 3: Elevations ranging from 380 to 549 meters, featuring alternating convex and flat hilltops due to the presence of sedimentary capping. |
According to the soil class mapping, conducted by De Sousa (2015), the main soils present in the Goiás Project region are Latosols, Argisols, and Dystrophic and Eutrophic Litholic Neosols, exhibiting a stony structure and a medium, gravelly texture associated with strongly undulating relief. Their main characteristics are described below, as proposed by De Sousa & Rodrigues (2018).
In general, latosols are non-hydromorphic mineral soils, characterized by a latosolic B horizon with Fe₂O₃ grade exceeding 18%. They represent highly weathered, advanced-stage soils, resulting from intense transformations of the parent material.
In the Iporá region, the argissols are represented by two classes: Dystrophic Red-Yellow Argissol, with moderate yellow coloration and a coarse, gravelly texture, occurring on strongly undulating relief; and Dystrophic Red Argissol, developed on gently undulating relief, with a gravelly texture over granitic rocks and a sandy texture over Furnas Formation sandstones (Sousa, 2006).
Dystrophic Litholic Neosols are shallow, poorly developed soils composed of mineral or organic material, with a typical thickness of 20–40 cm and a texture ranging from sandy to clayey, with or without coarse fragments (gravel, stones, and blocks) (Embrapa, 1999).
The region is located between the Amazonian Equatorial and Atlantic Tropical provinces and is characterized by a typic savannah-cerrados vegetation cover. This coverage ranges from dense cerrado (cerradão) to typical cerrado, with extremes of shrubby grassland. In rare terrains, especially over mafic-ultramafic rocks, rectilinear vegetation of the large-scale forest type occurs, with only small, isolated islands remaining today to testify to the past forests (Moreton, 2001).
The native vegetation is discontinuous and altered. Pastures occupy approximately 75% of the area, while riparian forests and conservation areas represent 15% of the territory. Agricultural lands comprise the remaining 10% (De Sousa & Rodrigues, 2018).

6 | GEOLOGICAL SETTING, MINERALIZATION, AND DEPOSIT TYPE |
The geology of Brazil comprises a significant portion of ancient craton basement rock from the Precambrian overlain by sedimentary rocks and intruded by igneous activity; all of which has been impacted by the rifting of the Atlantic Ocean. Much of the basement rock underlying Brazil formed during the Precambrian, including the São Francisco Craton. In the Mesoproterozoic, the Rio de la Plata craton (beneath southern Brazil), the Amazonia Craton and the small São Luis Craton and sections of the Congo Craton which form the basement rock were joined with Africa. Figure 6-1 illustrates the geological setting of Brazil and the location of the Iporá project.
Figure 6-1: Geological map of the South American Platform (after Hasui and Almeida, 1985).
S-K 1300 Technical Report – Iporá REE Project – Goiás State, Brazil | Page 22 |
6.1 | Regional Geology |
The Iporá project is located south of the Southern Amazon Craton, west of the São Francisco Craton and sits near the contact between the Paraná Basin and the Brasiliano (or Brasília) Fold Belt (BFB) (Figure 6-1).
Specifically, the project is located within the Tocantins Structural Province in the BFB, which is part of the Goiás Magmatic Arc. The Tocantins Province is composed of a series of SSW-NNE trending terranes of mainly Proterozoic ages which stabilized in the Neoproterozoic in the final collision between the Amazon and São Francisco cratons. The Tocantins Province is divided into an eastern and western section. The eastern section is located in a N-S arc-shaped folded belt (the BFB) which extends northwards to the state of Tocantins and southwards to the state of Minas Gerais (Figure 6-2). The BFB consists of a deformed mobile belt deposited during the Meso to Neoproterozoic in the western margin of the São Francisco Craton over a basement of Paleoproterozoic granitic-gneissic terrane affected by Mesoproterozoic deformation. The Serra Verde rare earth project is located at the northern end of the BFB, while the southern end is represented by the Araxa rare earth deposit. The Iporá project lies approximately at the center of the BFB on the western margin of the belt (Figure 6-2).
The Tocantins Province orogen was formed by the Brazilian/Pan-African cratonic collision, located in the central-north portion of Brazil between the Amazon, São Francisco, and Paraná Cratons. The mobile folding belts part of the Tocantins Province is composed of supracrustal volcano-sedimentary rocks, granitic intrusions and subordinate basic-ultrabasic bodies. The Brasilia, Araguaia and Paraguay ranges are situated within this geotectonic domain, with the Brasilia Fold Belt around a west edge of the São Francisco Craton oriented in a preferential north-south direction, and the Araguia and Paraguay belts bordering to the east and southwest of the Amazonian Craton.

The representative of Goiás Magmatic Arc in the region is the Neopreoterzoic Iporá Granite, composed of granites, granodiorites and quartz monzonites. These rocks are mainly formed by large microcline crystals (~5cm), quartz and amphibole as the main mafic phase, which occurs associated with biotite as hypidiomorphic crystal aggregated. The accessory phase is composed of zircon, sphene, apatite, allanite and other opaque minerals. This unit has calcalkaline affinity, and are correlated to the batholiths of juvenile magmatic arc (Pimentel & Fuck, 1987a).
The North border of the Paraná Basin, in Central Brazil, is characterized by an erosive scenario very active during the Upper Cretaceous with the intrusion of alkaline magmatism in the region. This magmatism is represented by two main provinces: Goiás Alkaline Province and Alto Paranaíba Igneous Province. It is set in groups of intrusions in Goiás and Minas Gerais states, disposed in linear arrangements parallel (Az 125º), some hundreds of kilometers apart (Dutra et al., 2012).
S-K 1300 Technical Report – Iporá REE Project – Goiás State, Brazil | Page 24 |
6.2.1 | Goiás Alkaline Province |
The Goiás Alkaline Province (GAP) is a late cretaceous alkaline igneous province, stretching 250 km in a NW-SE direction and up to 70 km wide. It includes mafic-ultramafic complexes in the northern portion, subvolcanic intrusions in the central region and volcanic products south, with several dikes (Junqueira-Brod et al., 2005).
The Córrego dos Bois alkaline complex covers an area of approximately 33 km² and corresponds to the largest of the northern GAP complexes. (Dutra et al., 2012).
The Córrego dos Bois Complex is formed by central zoned intrusions with magmatic differentiation of the central dunite – periodotite – pyroxenite – alkaline gabbro – nepheline syenite for the first magmatic event, between 75 and 81 Ma (Danni 1974). The second magmatic event is characterized by subvolcanic intrusions, as lamprophyres, nefelinites and analcimites in soles and dikes, around 60 Ma. The rocks are described as dunites, wehrlites, olivine-pyroxenites and websterites. Besides the main mafic components of these rocks, as olivine, plagioclase, augite, the secondary components are zeolites, biotite and opaque minerals.
The Córrego dos Bois Complex is represented in (5) on Figure 6-3.

6.3 | Property Geology |
Mapping by Atlas on the Iporá tenements has identified five major lithographic units. These units are:
● | Ribeirão de Santo Antonio Metagranite | |
● | Iporá Granite | |
● | Paraná Basin sedimentary rocks | |
● | Alkaline units of the Goiás Alkaline Complex | |
● | Laterites |
6.3.1 | Ribeirão Santo Antônio Metagranite |
The Ribeirão Santo Antônio metagranite occurs in the east portion of tenement 860.438/2022, at elevations above 600m, outcropping predominantly as blocks. The rock is composed of plagioclase, k-feldspar, quartz and biotite and displays a granolepdoblastic texture with foliation defined by biotite (Figure 6-4). Additionally, plagioclase augen porphyroclasts may be present.
Figure 6-4: Hand Specimen and Outcrop of Ribeirão Santo Antônio Metagranite
S-K 1300 Technical Report – Iporá REE Project – Goiás State, Brazil | Page 26 |
6.3.2 | Iporá Granite |
The representative of Goiás Magmatic Arc in the region is the Neopreoterzoic Iporá Granite. The Iporá Granite rocks correspond to an undeformed syeno-granite, with isotropic coarse texture (Figure 6-5) composed of euhedral alkali-feldspar and granular quartz (>20% of the rock), and very few mafic phases, a very fine aggregate, probably composed of allanite, biotite and oxides. The outcrops are in the form of boulders ranging from a meter to tens of meters in size.
Figure 6-5: Typical Outcrop of Iporá Granite and Hand Specimens
6.3.3 | Paraná Basin Sediments |
The Paraná Basin sediments comprise sandstones and conglomerates from the Furnas and Ponta Grossa formations. These quartz-rich siliciclastic formations belong to an extensive, neo-ordovician to late cretaceous South American intracratonic basin, developed over a continental crust and filled by sedimentary and volcanic rocks. The sandstones are well selected, reddish to white and cemented by silica and Fe hydroxides, and the conglomerate is composed of quartz pebbles and granules with matrix of fine quartz and mica sand and kaolinite (Figure 6-6).
S-K 1300 Technical Report – Iporá REE Project – Goiás State, Brazil | Page 27 |
Figure 6-6: Paraná Basin Sediments - Monomitic Conglomerate composed of Quartz Pebbles (top left), Red Cemented Sandstone (bottom left) and Sandstone Outcrop (right)
6.3.4 | Goiás Alkaline Complex |
At the Paraná Basin’s edges, late Cretaceous alkaline magmatism took place and formed large intrusive complexes with a wide range of rock compositions. The Córrego dos Bois Complex is one of eleven mapped alkaline complexes within the GAP and is the main alkaline complex of the Iporá project. Within the project area, mapped lithotypes related to the Córrego dos Bois Complex are syenite, ultramafic (peridotite and pyroxenite) and mafic (gabbro) rocks and trachyte (Figure 6-7).
The syenite is composed mainly of alkali feldspar and mafic minerals, pyroxenes and amphibole, with little altered nepheline relicts. Mafic rocks include gabbro and subvolcanic products, composed of plagioclase, pyroxene and small (<5mm) phlogopite crystals. The ultramafic rocks are represented in the area by a peridotite, composed of fine olivine and pyroxene crystals. The trachytes are a subvolcanic product of syenites, with feldspar phenocrysts embedded in a grey, volcanic matrix.
Rocks of Córrego dos Bois Complex tend to define the geomorphological setting of the region, preserving steep hills with dense, natural vegetation. It is possible to distinguish a different type of laterite generated by this unit, a muddy, silky and purple-reddish laterite with distinct characteristics.

Figure 6-7: Córrego dos Bois Complex Lithotypes: Syenite (top left), Mafic (top right), Peridotite (bottom left) and Trachyte (bottom right)
6.3.5 | Laterites |
The laterites are divided into two lithotypes: duricrust (Figure 6-8) and latosol soil (Figure 6-9). Observations about the laterites included grain size, color, composition of grains and cement, cement proportion, structures such as mottles, pores, presence of pisolites and oolites and transport.
A red latosol soil with little or no quartz, kaolinitic and micaceous composition is predominant in the area, and the presence of talc was noticed, indicating the ultramafic rocks as the parental rock. Some of the red latosol presents kaolinitic composition, with low quartz e sometimes shows fragments of saprolite granites, suggesting the Iporá Granite as parental rock.
The duricrusts also vary according to its source. Pale beige duricrusts are associated with Paraná Basin rocks, whereas red, purple, pisoolitic and ferriferous duricrusts are related to igneous, especially ultramafic rocks. Sometimes the duricrusts have a transported aspect, but most times they appear as an in-situ unit.

6.4 | Deposit Type |
The geological setting of the Iporá Project is typical of a regolith-hosted REE deposit (ion-adsorption REE deposits or ionic clay), which combines type-A alkaline granites with supergene enrichment, with the southern China deposits being the type example. The formation of this deposit type can be divided and summarized into two stages (Trench et al, 2025):
i. | The formation of parent rocks: parent granites are peraluminous, siliceous, and alkaline and contain various REE-bearing accessory minerals. they must be relatively enriched in REEs. | |
ii. | Weathering of parent rocks and enrichment of REEs: At this stage, weathering causes the decomposition of rock-forming minerals, leaching elements such as Ca, Na, and K and forming clays. Similarly, susceptible accessory REE minerals are decomposed, replacing the REEs in solution and subsequently it deposits in the regolith, ionically adsorbed by clay minerals, mainly kaolinite and halloysite. At this stage, the REE grade in the regolith can increase 1.5 to 10 times compared to the parent rock. |
S-K 1300 Technical Report – Iporá REE Project – Goiás State, Brazil | Page 31 |
Trench et al., (2025) further write that these deposits typically comprise four layers: 1) a topsoil layer (A horizon); 2) a completely weathered layer (B horizon); 3) a partly weathered layer (C horizon); and 4) a bedrock layer (D horizon) (Figure 6-10).
The orebodies are mainly located in the central and lower part of the B horizon and upper part of the C horizon for regolith developed over granite, and middle and upper B horizon for regolith over metamorphic rocks. The thickness of the orebodies varies between deposits and between different locations in the same deposit. Generally, it is several meters to 10 meters thick.

7 | EXPLORATION |
Atlas carried out exploration during June and July 2025 on tenements 860.440/2022, 860.438/2022, 860.439/2022 and 860.667/2023. The exploration consisted of surface mapping, surface sampling and an auger sampling program.
7.1 | Surface Mapping |
Atlas mapped the above-mentioned tenements at a scale of 1:12.500. The majority of the tenements have extensive lateritic overburden, but geology was inferred from surface outcrops. Figure 7-1 shows the mapping.
Figure 7-1: Geological Map of Atlas Permits
7.2 | Surface Sampling |
Atlas collected a total of 161 samples across the four tenements and the five major lithotypes identified on the property (Figure 7-2). The goal was to try and establish a correlation between lateritic bodies and possible sources of REE. The samples collected comprised:
● | Laterites (133): 20 lateritic duricrust samples, 113 latosol soil | |
● | Paraná Basin (4): one conglomerate sample, three sandstones samples | |
● | Goiás Alkaline Province (20): 13 syenites samples, four ultramafic rocks samples and three mafic rocks sample. | |
● | Iporá Granite (3): three granites samples. | |
● | Santo Antônio Metagranite (1): one metagranite sample. |
S-K 1300 Technical Report – Iporá REE Project – Goiás State, Brazil | Page 33 |
The average results are shown in Table 7-1, while significant results are shown in Table 7-2.
From Table 7-1, it can be seen that there is a correlation between laterites developed over the GAP and Iporá Granite and high REO values. Chip samples from the GAP, Iporá Granite and Santo Antônio Metagranite also returned elevated levels of REOs.
Figure 7-2: Map of Surface Samples with Relative Grade Ranges
Table 7-1: TREO and MREO Averages for Surface Samples
Samples (Unit) | TREO (average) | MREO (average) | Lithotype | N° |
Laterites - all | 537.77 | 101.39 | Latosol soil and Duricrust | 133 |
Laterites related to GAP and/or Iporá Granite | 605.32 | 111.72 | Latosol soil and Duricrust | 97 |
Laterites related to Paraná Basin | 355.75 | 73.56 | Latosol soil and Duricrust | 36 |
Goiás Alkaline Complex | 600.76 | 142.51 | Mafic-Ultramafic and syenite | 20 |
Paraná Basin | 355.64 | 77.96 | Sandstones and conglomerate | 4 |
Iporá Granite | 694.51 | 160.97 | Syenogranite | 3 |
Santo Antônio Metagranite | 917.46 | 265.51 | Metagranite | 1 |
From Table 7-2, it can be seen that the majority of the high REO values come from laterites, with outcropping from the Goiás Alkaline Complex the next largest contributor.

7.3 | Drilling |
Atlas conducted an auger drilling campaign over the four tenements, completing 18 drillholes for 170.68 m of drilling (Figure 7-3). The average depth of the auger holes was 9.48 m.
The results indicate a large, approximately 10 m thick, near-surface mineralized horizon. The average chemical index of alteration (CIA) for drillholes is 93.05%, indicating advanced weathering in the regolith system.

8 | SAMPLE PREPARATION, ANALYSES, AND SECURITY |
The 2025 exploration program saw Atlas collect 133 surface samples and drill 18 auger holes for the purposes of REE analysis.
8.1 | Auger Sample Preparation and Analyses |
The auger holes were sampled according to lithology, but typically, most samples were one meter long. The samples were submitted to SGS Brazil and divided into two parts for different analysis, according to:
● | Global grade analysis (SGS Brazil) | |
● | Leaching tests (SGS Brazil) |
8.2 | Quality Assurance and Quality Control |
The surface sampling campaign included soil and rock chip samples of all lithology and layers across Atlas Critical Minerals’ mineral rights. The auger drilling campaign tested possible targets to evaluate the mineralization potential. Both campaigns had all geochemical analysis performed by SGS-Geosol, an analytical laboratory located in Vespasiano, Brazil (“SGS-Geosol”). SGS-Geosol is ISO 14001 and 17025 accredited by the Standards Council. SGS-Geosol is an independent third-party and provides services pursuant to arms-length contracts.
The SGS-Geosol assays were done using the protocols ICM90A, ICP95A and IMS95A. ICM90A is an aqua regia digestion (partial) while the ICP95A and IMS95A are four-acid digestion (near total).
The OREAS standards used for the QAQC are certified using borate / peroxide fusion digestion (total) so expected values are maximal. SGS note that the OREAS certificates state that four-acid assays can match the total digestion methods for most elements.
The auger drillholes were vertical and the reported intervals corresponded to the true thickness. The cores were placed in boxes, aligned and measured by the technician or geologist for core recovery. The core boxes were identified with a code, a hole ID and tags. The logging and sampling were performed in the field. The sample intervals were generally one meter in length, varying depending on the lithological contact, and the material for chemical analysis consisted of the right half of the core, resulting in samples with an average weight of 5 kg. These samples were then gathered in a labelled bag, and the remaining half is kept at the box with the sample ID tag, for reference. The bagged samples were then sent to SGS-Geosol.
All samples received at SGS-Geosol were inventoried and weighted prior to being processed. Drying was done to samples having excess moisture. Sample material was crushed using jaw crushers. The SGS-Geosol analytical method used for Atlas samples is one of their standard packages. Analytical results were sent electronically by SGS-Geosol directly to Atlas and results were compiled in an MS Excel spreadsheet by the project geologists.
Through the implementation of these protocols, Atlas ensured the quality and integrity of data, maintaining full traceability and accuracy in the results and in the processes related to geological interpretation and evaluation.
8.3 | QA/QC Control Samples |
Atlas supplied the final database on September 23, 2025. The database included a total of 173 auger samples, 18 blanks, and 18 Certified Reference Material (CRM).
S-K 1300 Technical Report – Iporá REE Project – Goiás State, Brazil | Page 38 |
The QAQC program consists of inserting a blank or a CRM into the sample sequence. Three (3) different CRMs were used during the project, OREAS 460, OREAS 461, and OREAS 463 which are commercial standards prepared and certified by Ore Research & Exploration. OREAS is ISO 17034 and 9001 accredited for quality production of CRMs.
● | OREAS 460 is an ore grade, rare earth element (TREO = 0.53%) matrix-matched certified reference material. | |
● | OREAS 461 is an ore grade, rare earth element (TREO = 1.06%) matrix matched. | |
● | OREAS 463 is an ore grade, rare earth element (TREO = 2.08%) matrix matched. |
8.3.1 | Blanks |
A total of 18 blanks were inserted into the sample sequence and analyzed at SGS Laboratories. Dysprosium and Terbium return acceptable quality control results below 5 times the detection limit (Figure 8-7). Neodymium, Praseodymium, Lanthanum, and Cerium returned varied and unreliable results representing possible discrepancies (Table 8-7).

No property inspection has been completed at this time.
10 | MINERAL PROCESSING AND METALLURGICAL TESTING |
Atlas conducted preliminary metallurgical test work on the auger samples from the Iporá project.
10.1 | Leaching Tests |
Atlas conducted leach tests on samples from 15 auger holes. These holes had returned the best assays from the drill campaign and Atlas chose the mineralized intervals for leaching.
A yield of 25% TREO in the leachate was considered the threshold for a positive result, with eight drillholes exceeding the threshold (Figure 10-1). The leached samples were from depths ranging between 3 and 11 meters. The leached samples belonged to the following lithotypes:
● | Laterites: 92% | |
● | Recent covers: 8% | |
● | Adjustment based on the updated lithologies | |
● | Cambrian granites are the source rock. |

22 | INTERPRETATION AND CONCLUSIONS |
SGS Geological Services Inc. (“SGS”) was contracted by Atlas Critical Minerals Corporation (“Atlas” or the “Company”) to complete a Property of Merit report for the Iporá Rare Earth Elements (“REE”) Project near the city of Patos de Minas, Brazil, and to prepare a Public Report in accordance with the §§ 229.601(b)(96) Technical report (subpart 229.1300 of Regulation S-K) written in support of a Property of Merit report on the Iporá Project.
This TRS conforms to the United States Securities and Exchange Commission’s (SEC) Modernized Property Disclosure Requirements for Mining Registrants as described in Subpart 229.1300 of Regulation S-K, Disclosure by Registrants Engaged in Mining Operations (S-K 1300) and Item 601 (b)(96) Technical Report Summary.
Atlas has 12 exploration tenements to the east and north of the city of Iporá, in Goiás state in Brazil. Of the 12 tenements, Atlas focused on the exploration of four tenements immediately adjacent to Appia’s PCH ionic clay deposit, north of Iporá.
Atlas conducted surface mapping, surface sampling and auger sampling on tenements 860.440/2022, 860.438/2022, 860.439/2022 and 860.667/2023 during June and July 2025.
The results of the exploration suggest that the four mining rights of the Iporá Project present favorable conditions for ionic clay deposits. Regolith horizons were mapped in the four mining rights, as well as laterite layers associated with alkaline and Cambrian granite rocks. These laterites have grades compatible with ion-adsorption REE deposit type, from 900 to 1500 ppm TREO, as evidenced by both surface and auger samples.
Based on the exploration results, the central-eastern regions of mining right 860.440/2022 and the western regions of 860.438/2022 comprise the most favorable area for a regolith-hosted REE target, comprising a laterite associated with alkaline rocks of the GAP with an area of approximately 8 km² and two other smaller laterites bodies, reaching up to 4 km², superimposed on the Iporá Granite.
The initial metallurgical test work indicated that TREO recoveries of 36% and HREO recoveries up to 55% were possible.
S-K 1300 Technical Report – Iporá REE Project – Goiás State, Brazil | Page 52 |
23 | RECOMMENDATIONS |
The delineation of laterites through geological mapping provides an estimate of the size of this layer in the mining rights, but for a better understanding of the laterite packages for future exploration, LiDAR topographic surveying and drill holes with depths reaching fresh rock are suggested, with a minimum penetration of two meters into the fresh material. This will guide a better understanding of the distribution of the regolith profile.
For geological mapping, it is suggested to increase the density of points on the eastern and western edges of the set of four mining rights to identify and/or confirm REE parent rocks and better delineate laterites. To optimize the geological mapping, detailed geophysics using magnetometry and gamma by drone are suggested. Detailed geophysics (mag and gamma) can also spot the occurrence of alkaline rocks not identified in the geological mapping.
The leaching results showed satisfactory recoveries in 8 holes of 15 holes sampled. It is recommended that further metallurgical sampling be conducted to better determine the leachability and probable recoveries of the laterite.
Atlas has proposed a three-phase exploration program for the Iporá project:
The first phase will target the development of mineral resources on mineral rights numbers 860.440/2022, 860.438/2022, 860.439/2022 and 860.667/2023. The planned activities for this block are described below:
● | The work will begin with Geophysical Magnetometric and Gamma Survey (Drone MAG), Aerophotogrammetry, and a detailed topographic surveying using Lidar. | |
● | In addition, the program will include a drilling campaign, supported by the implementation of all necessary infrastructure for a complete sample management and quality control chain. This will encompass chemical analyses, proper sample storage in a dedicated facility, and the application of rigorous QA/QC protocols. | |
● | The owner’s team will be responsible for managing and supervising field activities. | |
● | Metallurgical Testing and SK-1,300 resource report. |
The second phase will target the development on mineral rights 860.668/2023, 860.669/2023, 860.679/2023, 860.205/2018, 860.206/2018, 860.437/2022, 860.441/2022, and 860.666/2023 to cover the 12 mineral rights of the region. The planned activities for this group are described below:
● | Detailed Geological Mapping; | |
● | Surface Sampling; | |
● | Exploration Auger Drilling; | |
● | Chemical Analysis and Leaching Tests. |
In the final stage of the material property exploration plan, the target will be the development of mineral resources on mineral rights selected by the second phase. The planned activities for this phase are described below:
The work will begin with Geophysical Magnetometric Survey (Drone MAG), Aerophotogrammetry, and a detailed topographic survey using Lidar.
In addition, the program will include a drilling campaign, supported by the implementation of all necessary infrastructure for a complete sample management and quality control chain. This will encompass chemical analyses, proper sample storage in a dedicated facility, and the application of rigorous QA/QC protocols.
The owner’s team will be responsible for managing and supervising field activities related to drilling, Metallurgical Testing and SK-1,300 mineral resource estimate.
Given the prospective nature of the Iporá Project, it is QP’s opinion that the Project merits further exploration and that the proposed plan for further work by Atlas is justified. The proposed work program by Atlas will help advance the Project and will provide key inputs required to evaluate the economic viability of the Project.
The QP is recommending Atlas conduct further exploration, subject to funding and any other matters which may cause the proposed exploration program to be altered in the normal course of its business activities or alterations which may affect the program as a result of exploration activities themselves.
