Belo Horizonte, Brazil - Newsfile Corp. - July 21, 2026 - Atlas Critical Minerals Corporation (NASDAQ: ATCX) ("Atlas Critical Minerals" or the "Company"), a diversified critical minerals exploration company, today announced strong initial results from the maiden diamond drilling program at its 100%-owned Graphite Project (the "Project") in Minas Gerais, Brazil. Drilling at the first of the Project's three mineral tenements has now been completed, with all 20 drill holes intersecting graphite mineralization – a 100% success rate. Independent laboratory assays, conducted by SGS Geosol, have confirmed multiple wide, high-grade intervals of graphitic carbon ("Cg").

Key Highlights

100% Graphite Intercept Success:
All20 completed drill holes completed (totaling ~2,300 meters) intersected graphite mineralization, confirming continuity both along strike and at depth.
Outstanding High-Grade Intercepts:
33.78 meters at 7.97% Cg (drill hole MPDDH-0009)
22.66 m at 8.27% Cg in (MPDDH-0007)
11.00 m at 8.03% Cg (MPDDH-0002)
6.00 m at 9.55% Cg and 19.36 m at 6.09% Cg (MPDDH-0006)
Extensive Geophysical Trend Identified:
Geophysical data indicates a potential 11-kilometer (~6.8-mile) mineralized trend, providing a robust pipeline for ongoing drill targeting.
Near-Surface High-Grade Mineralization:
Many of the strongest intercepts occur close to surface, suggesting potential for low-cost open-pit mining.
Progressing Toward a Maiden Resource Estimate:
SGS, a leading independent mineral evaluation company, has been retained to prepare a Maiden Mineral Resource Estimate ("MRE"), expected in Q4 2026.
Rapidly Growing Market: The global graphite market is forecast to reach USD 36.4 billion by 2030, growing at a 15.1% CAGR, driven by surging demand for energy storage and electric vehicle. Benchmark Mineral Intelligence estimates that 97 new graphite mines will be needed by 2035 to meet global demand.

Drilling Program and Geophysical Targeting

Atlas Critical Minerals designed its 2026 diamond drill program based on the results of prior exploration work, including geological mapping, grab sampling, and a ground geophysical survey. The full 2026 program totals approximately 6,000 meters distributed across the Project's three tenements. The Company has now completed 20 drill holes for approximately 2,300 meters at the first tenement, all intersecting graphite mineralization.

Prior to drilling, the Company completed 27.5 kilometers of ground geophysical data acquisition. Strong anomalies – characterized by high chargeability and low resistivity, typical of graphite mineralization – were identified along the entire 11-kilometer strike length, confirming substantial exploration potential.

The Company's exploration activities at the Project are conducted in accordance with Item 1300 of Regulation S-K ("Regulation S-K 1300"), the U.S. standard for mineral property disclosure. All technical work is supervised by Marc-Antoine Laporte, a recognized critical minerals geologist with SGS Canada Inc. ("SGS") who serves as a Qualified Person for graphite under Regulation S-K 1300. Mr. Laporte authored the Technical Report Summary ("TRS") for the Project, which was last filed with the U.S. Securities and Exchange Commission on November 12, 2025. The TRS includes results from initial metallurgical testwork conducted at a specialized graphite laboratory in the United States, demonstrating that material derived from Project samples achieved both battery-grade and nuclear-grade qualification standards, providing an early and positive indication of the Project's potential to produce high-purity, high-performance graphite materials.

Graphite: A Critical Mineral

Graphite is the dominant anode material in lithium-ion batteries, essential for energy storage systems and electric vehicles. Recognized as a critical mineral by several governments, including the U.S., high-grade natural flake graphite can be upgraded into battery-grade active anode material.

Atlas believes the Project's high in-situ grades and favorable flake characteristics, hosted within graphitic schists of the Macaúbas Group (Araçuaí Orogen), position it well to help address the rapidly growing supply gap in the Americas.

"These are outstanding initial drill results that validate our earlier exploration work," commented Marc Fogassa, Chairman and Chief Executive Officer of Atlas Critical Minerals. "Every one of the first 20 holes intersected graphite - including a nearly 34-meter interval averaging close to 8% graphitic carbon - much of it near surface and favorable for open-pit development. With geophysics outlining an approximately 11-kilometer mineralized trend, two additional contiguous tenements still to be drilled, and SGS engaged to prepare our maiden resource estimate, we are advancing rapidly to unlock what we believe to be one of the most compelling graphite discoveries in the Americas."
