Maiden RC Drill Program At The Arapaima Project

VANCOUVER – Spark Energy Minerals Inc. reported on the maiden Reverse Circulation (RC) drill program at the Arapaima Project in Brazil’s Lithium Valley. All five maiden drill holes intersected broad rare earth (REE) and gallium (“Ga”) mineralization from surface to the bottom of the drilled interval. These results represent the complete assay data from all five first-pass holes — not selected samples — and the consistent mineralization across 100% of drilling provides early evidence of a laterally continuous critical minerals system. Further drilling will be required to determine the full depth extent of mineralization.
The intervals reflect broad and consistent rare earth mineralization encountered in every hole of the maiden drill program. The repetition of similar thicknesses and grades across all five first-pass holes supports the interpretation of a coherent and laterally continuous mineralized system, rather than isolated high-grade zones.
Importantly, magnet rare earth oxides (MREO) — including neodymium, praseodymium, dysprosium, and terbium — comprise up to 33% of TREO across the maiden drill program. These magnet elements represent the most strategically significant segment of the rare earth spectrum, forming the core components of high-performance permanent magnets used in electric vehicles, wind turbines, aerospace systems, robotics, and defense technologies. As governments and manufacturers seek to diversify supply chains amid tightening export controls and supply concentration, projects demonstrating meaningful magnet rare earth content have attracted increased strategic interest.
The presence of gallium mineralization beginning at surface in every drill hole underscores the near-surface character of the system and its emerging strategic importance. Gallium is a critical input in advanced semiconductors, AI processing architecture, high-frequency radar systems, and LED technologies. With global supply highly concentrated and subject to export restrictions, new gallium discoveries outside traditional supply channels have attracted increased strategic interest.
The five maiden drill holes were spaced at meaningful step-out distances, with an average separation of approximately 380 metres. The closest spacing between holes was 301 metres (between ARA-RC-002 and ARA-RC-004), and the widest spacing was 423 metres (between ARA-RC-002 and ARA-RC-003).
The consistent intersection of magnet rare earth and gallium mineralization across holes separated by several hundred metres strengthens the interpretation of a laterally continuous mineralized system across a meaningful footprint.
The five-hole RC program represents the first drilling campaign ever conducted on Spark’s flagship Arapaima Project. Such uniformity in a first-pass program supports the interpretation of lateral continuity across the tested area — a notable outcome in early-stage drilling. The results support the interpretation that Arapaima hosts a coherent and vertically developed supergene mineralized system formed through deep tropical weathering of granitic host rocks.
