Observed Surface Sample Grades up to 28,870ppm TREO and 23.2% TiO2

Belo Horizonte, Brazil--(Newsfile Corp. - July 17, 2025) - Atlas Critical Minerals Corporation (OTCQB: JUPGF) ("Atlas Critical Minerals" or the "Company") is pleased to report strong initial rare earth and titanium results from its Alto do Paranaíba Project (the "Project"), located in the western part of state of Minas Gerais, Brazil. The project demonstrates significant potential for near-surface rare earth and titanium mineralization within the "Mata da Corda" Group geological sequence. SGS Canada, Inc. ("SGS") was retained to prepare technical reports under U.S. Regulation S-K 1300. In particular, Marc-Antoine Laporte and Yann Camus from SGS are Qualified Persons for the Project. SGS is well-known as a global leader in testing, inspection and certification of mineral properties and projects.

The Project comprises mineral rights totaling more than 25,000 hectares, strategically positioned within a major volcano-sedimentary geological sequence. The extensive Project area has been divided into three exploration blocks for ease of exploration activities as shown in Figure 1.

The Mata da Corda Group consists of the sedimentary Capacete Formation crosscut by the volcanic Patos Formation. This geological setting, with its geochemical signature confirmed to be related to Brazilian late Cretaceous Alkaline Provinces, provides outstanding exploration potential for mineralization for both rare earth elements and titanium.

Surface Sampling Results

The Company's initial exploration campaign has included 770 surface samples (rock and soil), which demonstrated consistently high grades across all three blocks:

Block 1 Highlights:

• 5,984 ppm TREO; 1,700 ppm MREO; 14.8% TiO₂ (Sample APPPA00152)
• 4,897 ppm TREO; 1,301 ppm MREO; 13.9% TiO₂ (Sample PCP-000019)
• 4,648 ppm TREO; 1,246 ppm MREO; 17.4% TiO₂ (Sample APPPA00111)

Initial Auger Drilling Campaign Delivers Strong Near-Surface Results

Initial auger drilling comprised 11 drillholes totaling 144 meters, with 178 core samples analyzed (including 22% QA/QC control samples). The drilling successfully intercepted high-grade, near-surface mineralization:

Average TREO grades by block demonstrate consistent mineralization: Block 1 averaged 3,157 ppm TREO; Block 2 averaged 2,312 ppm TREO; and Block 3 averaged 4,906 ppm TREO. Notably, Block 3 showed high Nd+Pr averages up to 1,108ppm.

Geological Setting and Mineralization Model

The Project area benefits from intense laterization processes typical of Brazil's tropical climate, which has led to enrichment of titanium and rare earth elements within the weathered profile. The mineralized sequence occurs within extensively oxidized zones of the Mata da Corda Group, with drilling reaching maximum depths of approximately 21 meters.

The strong positive correlation between rare earth elements and titanium, combined with the sequence's intense magnetism, makes the geological unit highly responsive to geophysical surveys, facilitating future exploration targeting.

Quality Assurance/Quality Control

All samples were analyzed by SGS Geosol, considered to be the premier analytical laboratory in Brazil and used by major mining companies. Quality control samples, such as blanks, duplicates and standards (CRM) were inserted into each analytical batch. For all analysis methods, the average number of QA/QC represented 22% of the analytical run.

Terminology: TREO means Total Rare Earths Oxides, MREO means Magnetic Rare Earths Oxides, and TiO₂ represents titanium dioxide.
