Rare Earths Americas Establishes the Foothills Rare Earths District, Expanding Beyond Shiloh with Multiple High-Priority Targets

Highlights:

• What began as exploration centered on the Shiloh target has evolved into the Foothills Rare Earths District, which incorporates Liberty Peak and three principal target areas, resulting in a district-scale exploration footprint approximately 17.5 times larger than the original Shiloh area
• Early exploration drilling at Liberty Peak, where drilling has intercepted monazite-bearing sands similar to those found at Shiloh more than 50 kilometers (km) away, underscores the exploration potential across the emerging district
• 260,000+ acres of airborne radiometric and magnetic surveys are planned in the second half of 2026 across Targets 1, 2 and 3, linking Shiloh and Liberty Peak to create the broader Foothills Rare Earths District
• Drilling underway at Liberty Peak with over 8,000 meters (m) planned for 2026 and over 2,000m drilled in 2Q26 alone.
• Over 4,600m drilled at Shiloh in 2Q26 testing saprolite potential, and diamond drilling underway to assess bedrock enrichment (assays results pending)
• The active land position across the district at the end of 2Q 2026 totaled 4,254 acres, a 53% increase over 1Q 2026

MANCHESTER, Ga.--(BUSINESS WIRE)--Rare Earths Americas, Inc. ("REA" or the "Company") is expanding beyond its flagship Shiloh Project to establish the Foothills Rare Earths District (the “District”), a large and growing exploration district in Georgia, USA. Supported by continued exploration drilling at Shiloh and an increasingly refined geological model, the Company believes the mineralized sands system may extend across multiple properties, including the adjacent Liberty Peak property and three additional high-priority exploration targets (see Figure 1). Collectively, these properties form the Foothills Rare Earths District, which covers an area approximately 17.5 times larger than the original Shiloh target area of over 22,000 acres. Appendix A presents additional drilling information and figures associated with this release.

Areas shown include active land positions (defined in the “Strategic Land Expansion Strengthens District-Scale Growth Opportunity” section below) as well as prospective land that remains subject to finalized land and access agreements with REA.

Increasing Confidence in District Scale Potential — As previously released (see here), extensive drilling over the first quarter reinforced the Company’s exploration thesis that a potential for monazite-bearing sands systems across the Shiloh property exists. The Company believes the sands system has district-scale continuity, extending from the Shiloh property into adjacent northeastern areas, including the Liberty Peak property (see Figure 1), thereby establishing the Foothills Rare Earths District.

To strengthen the exploration model, sonic and direct push drilling at the Liberty Peak property commenced late in the first quarter of this year. Initial assays have yielded encouraging results, with mineralized intercepts up to 10 meters wide and multiple holes ending in enrichment, implying mineralization is potentially open at depth.

Early exploration drilling at Liberty Peak, where drilling has intercepted monazite-bearing sands similar to those encountered at Shiloh more than 50 kilometers away, further supports the district-scale potential of the emerging Foothills Rare Earths District (see Figures 2 and 3). The presence of laterally extensive monazite-bearing sand units may be indicative of deposit characteristics that, in some mineral sand operations, can be associated with advantages such as near-surface, free-dig mining conditions and the use of conventional mineral processing and beneficiation methods. However, the extent, continuity, economic significance, and metallurgical characteristics of these sands across the District have not yet been established and remain subject to further drilling, technical studies, and evaluation.

Highlights from initial drilling at Liberty Peak include:

• 26-DPBF-046 with >0.2% total rare earth oxides (TREO) from 0-10m
• 26-DPBF-060 with >0.2% TREO from 3.1 to 4.5m and 6.1-10.3m
• 26-DPWB-033 with >0.3% TREO from 4.5-7.6m and 10.7-11.8m

In addition, drilling at Shiloh has continued to deliver promising results consistent with those reported on June 15, 2026, increasing confidence that a broader monazite-bearing sands system exists as the Company advances toward defining a maiden resource.

Highlights from recent drilling at Shiloh include:

• 26-SRLC-020 with 0.95% TREO from 8.6-11.5m
• 26-SRLC-027 with 0.57% TREO from 7.7-9m
• 26-SRLC-039 with 0.93% TREO from 13.4-14.1m

Strategic Land Expansion Strengthens District-Scale Growth Opportunity — As of the end of the second quarter of 2026, the Company’s active land position under Exploration & Development Agreements ("EDAs"), mining leases and option agreements totaled 4,254 acres across the District, representing a 53% increase compared to the first quarter of 2026. In addition, REA has short-term access agreements and exploration agreements for initial assessments of prospective properties; total land position for these agreements totaled over 11,500 acres.

This continued expansion underscores the Company's ongoing land acquisition efforts and growing strategic footprint across the District. REA remains focused on further strengthening its land position as it advances exploration programs, generates new targets, and works to realize the district-scale potential of the Foothills Rare Earths District.

Next Steps — Given the initial promising drilling results, the Company is expanding its 2026 Georgia exploration program to include over 8,000m of sonic and direct push drilling at Liberty Peak. This is in addition to the previously announced 20,000m drill program at Shiloh. Rare Earths Americas will also undertake airborne radiometric surveys, geological mapping, and soil sampling across Target Areas 1–3 (See Figure 1) to further define and advance high-priority drill targets across the District. In total, the Company expects to invest approximately $15 million over 2026 to unlock and define the District's rare earths resource potential. The Company will release additional assay results and exploration updates throughout the third quarter of 2026 and into year-end.

Rare Earths Americas’ CEO, Donald Swartz, commented: “What began as a targeted exploration program at Shiloh is evolving into what we believe could become a significant domestic rare earths district. Encouraging drilling results from both Shiloh and Liberty Peak, combined with our expanding land position, continue to strengthen our district-scale exploration thesis. We are focused on advancing multiple targets across the Foothills Rare Earths District while progressing toward a maiden resource at Shiloh and unlocking the broader potential of this emerging rare earths system.”

What are Rare Earths?

Rare earth elements are a group of 17 specialty metals critical to a wide range of advanced and everyday technologies. They are used in high-performance permanent magnets, particularly neodymium-iron-boron (NdFeB) magnets, which enable high strength and efficiency in applications such as robotics, electric vehicles, defense systems, wind turbines, and consumer electronics. In simple terms, motion generated by electricity is often powered by NdFeB magnets, making rare earths essential inputs in everyday items, from the motor that raises and lowers a car window to the motors used in drones and humanoid robots.

Of the 17 rare earth elements, neodymium (Nd), praseodymium (Pr), dysprosium (Dy), and terbium (Tb) are the key materials used in high-performance permanent magnets. Dy and Tb are particularly valuable due to their ability to enhance magnet performance at high temperatures.

According to Adamas Intelligence, China accounts for over 90% of global Dy and Tb production. This concentration has increased the strategic importance of developing new rare earth projects in other jurisdictions to support supply chain diversification and long-term demand growth.
