Spark intercepts 85 g/t Ga2O3, 1.20% TREO at Arapaima

Twelve-hole RC step-out program confirms near-surface gallium in every hole and extends the single Cruzeta target approximately 2.9 km westward into its western area Vancouver, British Columbia--(Newsfile Corp. - July 22, 2026) - Spark Energy Minerals Inc. (CSE: SPRK) (OTC Pink: SPARF) (FSE: 8PC) ( " Spark" or the " Company") is pleased to report assay results from twelve reverse circulation ("RC") drill holes (ARA-RC-009 to ARA-RC-020) at the Cruzeta target of its flagship Arapaima Project in Brazil's Lithium Valley, Minas Gerais State. The results materially expand the scale of Arapaima. Drilling confirmed near-surface gallium mineralization in every hole and extended the known mineralized trend approximately 2.9 kilometres westward, from the eastern area of the Cruzeta target into its western area.

The single Cruzeta target now defines a mineralized footprint measuring approximately 4.4 kilometres east-west by 1.5 kilometres north-south, interpreted as one broad, contiguous mineralized trend, giving Spark a substantially larger target area for continued drilling. Gallium Intersected from Surface in All Twelve Holes Gallium mineralization was intersected from surface in all twelve holes reported in this program, overlying a broader rare earth element ("REE") zone. Composite intervals include 30 m from surface at 69 g/t Ga ₂ O ₃ in ARA-RC-011 and 12 m from surface at 77 g/t Ga ₂ O ₃ in ARA-RC-012, with the highest individual 2 m sample returning 85 g/t Ga ₂ O ₃ from 10-12 m in ARA-RC-011.

Underlying rare earth mineralization returned composite intervals including 14 m at 3,125 ppm TREO and 32 m at 2,456 ppm TREO , with an individual 2 m sample of 12,039 ppm TREO (1.20% TREO) . All grades are in-situ analytical results; no metallurgical recovery is implied. Highlights Expanded footprint: the single Cruzeta target
