Atlas Lithium's Subsidiary Reports Outstanding Rare Earth Mineralization Across Two Project Types

Atlas Critical Minerals Reports Strong Results from Dual Deposit Strategy Covering Both Ionic Clay and Conglomerate-Hosted Rare Earth Systems

Atlas Lithium Corporation (NASDAQ: ATLX) ("Atlas Lithium" or "Company"), a leading lithium development company, is pleased to announce that its subsidiary Atlas Critical Minerals Corporation ("ACM") (OTCQB: JUPGF) has reported excellent results from its diversified rare earth portfolio strategy, establishing Brazil's most comprehensive rare earths project portfolio.

In particular, ACM has successfully demonstrated the potential viability of two distinct rare earth deposit types through its recent technical studies for the Iporá Project (in Goiás State) and Alto do Paranaíba Project (in Minas Gerais State), creating a compelling diversified strategy that provides multiple pathways to production across different deposit characteristics.

Key Highlights of Diversified Rare Earth Portfolio

Iporá Ionic Clay Project Highlights:

• High-grade drilling intercepts including 8 meters at 2,071 ppm TREO (Total Rare Earths Oxide) with 775 ppm MREO (Magnetic Rare Earths Oxide) in drillhole DHIP-0006

• Peak 1-meter interval achieving 3,822 ppm TREO and 1,803 ppm MREO

• Strong metallurgical results with MREO recovery rates exceeding 60% for critical permanent magnet elements

• HREO (Heavy Rare Earth Oxides) recovery rates of 55% and Yttrium recovery rates of 63%

Alto do Paranaíba Project Highlights:

• Near-surface mineralization featuring grades up to 28,870 ppm TREO and 23.2% TiO₂

• Consistent high-grade mineralization across all three exploration blocks

• Strong correlation between rare earth elements and titanium mineralization

The diversified approach provides ACM with reduced geological risk through multiple deposit styles, varied metallurgical processing approaches offering different cost structures and recovery rates, and enhanced optionality for development sequencing. Ionic clay deposits typically offer simpler processing with lower capital requirements, while conglomerate-hosted deposits can provide larger-scale resources.

"Our strategic stake in Atlas Critical Minerals provides shareholders with exposure to the broader critical minerals sector and strengthens Atlas Lithium's position within global supply chains for materials vital to energy transition and national security," said Marc Fogassa, Chief Executive Officer and Chairman of Atlas Lithium. "The outstanding results from both the ionic clay and conglomerate-hosted rare earth systems demonstrate the exceptional geological potential of our subsidiary's Brazilian portfolio."

Strategic Location Advantages

Both projects benefit from their strategic positioning in Brazil's established mining regions. The Iporá Project is located in Goiás State, home to Serra Verde, one of the only integrated rare earths mining and processing operations outside of Asia. The Alto do Paranaíba Project enjoys robust infrastructure including power, water, and roads, positioning both assets for potential development.

Atlas Critical Minerals now controls over 218,000 hectares of critical mineral rights in Brazil, encompassing projects in rare earths, titanium, graphite, and uranium - minerals essential for defense applications, electrification, and energy security.
