Vancouver, British Columbia — February 13, 2026 — Leads & Copy — Spark Energy Minerals Inc. (CSE: SPRK) (OTC Pink: SPARF) (FSE: 8PC) has announced the final assay results from its 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 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.
Highlights include magnet rare earth oxides (MREO) with up to 33%.
Rare Earth (TREO) Highlights – Magnet Rare Earth Oxides (MREO) up to 33%:
78 m grading 2,430 ppm TREO (21% MREO)
Including 10 m at 4,522 ppm TREO (25% MREO)
Including 2 m at 6,682 ppm TREO (33% MREO)
34 m grading 2,690 ppm TREO (22% MREO)
Including 4 m at 4,373 ppm TREO (24% MREO)
Including 6 m at 4,355 ppm TREO (21% MREO)
28 m grading 2,031 ppm TREO (21% MREO)
16 m grading 1,851 ppm TREO (22% MREO)
16 m grading 1,353 ppm TREO (22% MREO)
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.
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.
Gallium Intersected from Surface in All Five Maiden Holes:
94 m grading 63 g/t Ga₂O₃ from surface
54 m grading 46.45 g/t Ga₂O₃ from surface
58 m grading 52 g/t Ga₂O₃ from surface
46 m grading 49.10 g/t Ga₂O₃ from surface
44 m grading 47 g/t Ga₂O₃ from surface
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 meters. The closest spacing between holes was 301 meters (between ARA-RC-002 and ARA-RC-004), and the widest spacing was 423 meters (between ARA-RC-002 and ARA-RC-003).
The consistent intersection of magnet rare earth and gallium mineralization across holes separated by several hundred meters strengthens the interpretation of a laterally continuous mineralized system across a meaningful footprint.
According to Dr. Fernando Tallarico, CEO of Spark Energy Minerals, intersecting magnet rare earths and gallium in all five of the first drill holes ever completed on the property provides compelling early evidence of a coherent and systematic mineralized footprint. He added that the consistent vertical zoning and strong magnet rare earth content reinforce the strategic significance of the Arapaima Project within Brazil’s Lithium Valley.
