Atlas Critical Minerals Defines South America's Largest, Highest-Grade Reported Graphite Resource: 24.2 Million Tonnes, Including 17.2 Million Tonnes Indicated at 5.73% Graphitic Carbon

Indicated Grade Approximately 25% Higher Than the Measured and Indicated Grade of the Largest Known Graphite Deposit in the United States

Belo Horizonte, Brazil - Newsfile Corp. - September 29, 2026 - Atlas Critical Minerals Corporation (NASDAQ: ATCX) ("Atlas Critical Minerals" or the "Company"), a diversified critical minerals exploration company, today announced the maiden Mineral Resource Estimate ("MRE") for its 100%-owned Malacacheta Graphite Project (the "Project") in Minas Gerais state, Brazil. The MRE is contained in the Technical Report Summary ("TRS") filed as Exhibit 96.1 to the Company's Report on Form 6-K filed with the Securities and Exchange Commission ("SEC") today.

The TRS, including the MRE, was prepared independently by SGS Canada Inc. ("SGS"), a well-respected mineral evaluation company with a global footprint, in accordance with Subpart 1300 of Regulation S-K ("S-K 1300"). The MRE covers only one of the Project's three contiguous mineral tenements and is reported at a 2.0% graphitic carbon ("Cg") cut-off grade:

• Indicated: 17.2 million tonnes ("Mt") grading 5.73% Cg, containing approximately 986,000 tonnes of graphite.
  
• Inferred: 7.0 Mt grading 5.40% Cg, containing approximately 378,000 tonnes of graphite.
  

Based on a review by the Company of publicly available technical disclosures for graphite projects in South America, Atlas Critical Minerals believes that the Project is the largest graphite resource in South America reported under a globally recognized mineral reporting code (S-K 1300, NI 43-101 or JORC), as measured by contained graphite, and that it has the highest Cg grade among such resources. The Project's Indicated grade of 5.73% Cg is also approximately 25% higher than the 4.6% Cg Measured and Indicated grade reported for Graphite Creek in Alaska - described by the U.S. Geological Survey as the largest known flake graphite deposit in the United States - at the same 2.0% Cg cut-off grade. The Project's Indicated grade is also nearly double the 2.91% Cg Inferred grade at the Kilbourne Graphite Project in New York, which is reported under NI 43-101 at a lower 1.5% Cg cut-off.

Key Highlights

• Maiden Resource of Scale and Grade:
  
  • 17.2 Mt Indicated at 5.73% Cg and 7.0 Mt Inferred at 5.40% Cg, for approximately 1.36 million tonnes of contained in-situ graphite across both categories from only one of three contiguous mineral rights.
    
  • The large initial Indicated resource for the Project provides a robust foundation for the planned Preliminary Economic Assessment.
    

• 100% Drill Success with Wide, Consistent Intercepts:
  
  • All 21 diamond core holes (2,393.90 meters) returned significant graphite intercepts.
    
  • Highlights include 43.10 meters at 6.20% Cg, 17.30 meters at 10.62% Cg, and 14.20 meters at 9.30% Cg starting from surface.
    

• Near-Surface Mineralization Amenable to Open-Pit Mining:
  
  • SGS considers the deposit amenable to open-pit extraction.
    
  • More than half of the drill holes (11 of 21) intersected significant graphite within the first ~10 meters down-hole, including 26.20 meters at 7.51% Cg from 8.50 meters and 24.25 meters at 6.61% Cg from 8.80 meters.
    

• Only ~2.5 km of an ~11-km Graphite Corridor Drilled:
  
  • The resource was defined along approximately 2.5 kilometers of strike.
    
  • Approximately 8.5 kilometers of potential mineralization remains along the trend, including on the Project's two other tenements.
    
  • SGS reports that the deposit remains open along strike and at depth.
    

• Premium Product Credentials:
  
  • Concentrate obtained from Project samples along the ~11-km graphite corridor was previously sent to a well-respected laboratory in the United States that specializes in graphite for product specification studies.
    
  • As disclosed in a prior technical report summary filed with the SEC on November 12, 2025, the laboratory was able to qualify the concentrate for use not only in electric vehicle batteries but also in nuclear reactors, a qualification that requires meeting the industry's most stringent purity standard.

*Contained graphitic carbon is calculated by the Company as tonnage multiplied by grade. It is in-situ, rounded, and does not account for mining dilution, mining losses or processing recoveries.

Drilling Confirms Continuity, Width and Grade

The MRE is supported by a diamond drilling program of 21 HQ core holes totaling approximately 2,394 meters, completed in 2026.

• The program was designed from geological mapping and an induced polarization (IP) survey.
  
• Every drillhole returned significant graphite intercepts.
  
• The results show consistent mineralized widths and grades, supporting the geological interpretation and the Company's understanding of the deposit.
  
• Graphite mineralization shows continuity over approximately 2.5 kilometers along strike, and the system remains open for further expansion.

Substantial Room to Grow

• The MRE covers only one tenement (approximately 997 hectares) of three contiguous tenements totaling ~2,822 hectares.
  
• The reported drilling covers only approximately 2.5 km of strike - less than one-quarter of the Project's ~11 km graphite corridor - leaving ~8.5 km untested along the same mineralized trend.
  
• SGS has recommended continued drilling to extend the limits of the deposit and to upgrade its resource classification.
  

"This maiden resource is a defining milestone for Atlas Critical Minerals and, we believe, for graphite supply in the Americas," said Marc Fogassa, Chairman and Chief Executive Officer of Atlas Critical Minerals.

"Our maiden graphite report already points to a quality asset: our Indicated grade exceeds that of the largest known graphite deposit in the United States by approximately 25%. Beyond an already sizable initial resource, , we have drilled only about 2.5 kilometers of an 11-kilometer corridor, on just one of our three contiguous tenements. Importantly, samples from our Project have been processed, tested, and qualified by a well-regarded graphite laboratory in the U.S. for use in electric vehicle batteries and in nuclear reactors, two of the highest-value markets."

Next Steps

The Company will now focus on advancing the Project through additional exploration, metallurgical testwork and technical studies. It will continue to evaluate opportunities to expand and improve the Mineral Resource at the first tenement and across the Project's two other contiguous tenements. Planned work includes:

• Resource Expansion Drilling:
  
  • Drill-test the remaining ~8.5 kilometers of the graphite corridor, including on the Project's two other tenements.
    
  • Step-out and depth drilling at the first tenement, where the deposit remains open.
    

• Resource Upgrading: Infill drilling to convert Inferred Mineral Resources to the Indicated category, as recommended by SGS.
  
• Metallurgical Testwork: Flotation optimization, flake-size distribution and variability testing on the graphitic schist, as recommended by SGS.
  
• Economic Evaluation: Advance engineering and economic studies, including a Preliminary Economic Assessment ("PEA") targeted for Q2 2027.
  

Graphite: A Critical Mineral

Graphite is the dominant anode material in lithium-ion batteries, which are essential for electric vehicles and energy storage systems. High-purity graphite is also used in nuclear reactors and advanced industrial applications. Several governments, including the U.S., recognize graphite as a critical mineral. According to the U.S. Geological Survey, the United States had no domestic natural graphite production in 2025 and remained 100% reliant on imports.

• According to MarketsandMarkets, a commodity research firm, the global graphite market is projected to reach USD 36.4 billion by 2030, growing at a 15.1% CAGR.
  
• Benchmark Mineral Intelligence, a battery supply chain research firm, estimates that 97 new graphite mines will be needed by 2035 to meet global demand.
  

Atlas believes the Project's combination of scale, grade, near-surface mineralization and demonstrated purification performance positions it well to help address the growing supply gap. Furthermore, Brazil is a safer and more established mineral jurisdiction than many other countries where graphite is found. Additionally, the Project's location in Brazil allows for lower-cost, year-round mining potential, a significant advantage over deposits located in harsher climates.
