Spark Energy Minerals Reports New Lithium and Gallium-REE Assay Results from Flagship Brazil Project
New assays define three >1,000 ppm lithium anomalies at Cruzeta and expand the gallium-REE footprint at Caladão.
Vancouver, British Columbia -- October 17, 2025 - Spark Energy Minerals Inc. (CSE: SPRK) (OTCID: SPARF) (FSE: 8PC) reports new assay results from 103 surface samples collected at its flagship Arapaima Project in Brazil's Lithium Valley. The new results expand known lithium anomalies and support ongoing drill planning at the Cruzeta, Água Branca, Grota do Maquém, and Caladão targets. These results, together with the ongoing exploration work - including mapping, geochemical analysis, and sampling - further support the definition of high-priority critical-mineral drill targets.
Batch Highlights:
[list]
[*] Three lithium anomalies exceeding 1,000 ppm Li defined from surface rock samples at Cruzeta.
[*] Stream-sediment sample at the Caladão Target returned total rare earth oxide (TREO) values above 10,000 ppm (1%), extending the anomalous footprint southward.
[/list]
Samples were analyzed by SGS Geosol (Vespasiano, MG, Brazil), an internationally certified laboratory suitable for resource and reserve reporting. Preparation and analytical methods were selected by sample type; stream-sediment and rock/core samples were prepared and analyzed under SGS's standard protocols, and Spark's QA/QC program included routine blanks, duplicates, and certified reference standards.
The Company is finalizing logistics and permitting for its initial diamond drill program at the Cruzeta, Água Branca, and Grota do Maquém lithium targets, and for air-core or reverse-circulation drilling at the gallium-REE Caladão Target, located adjacent to recent publicly reported ionic-clay gallium and REE discoveries developed over the Caladão Granite. Drill targeting will be guided by ongoing geochemical interpretation and field mapping. Initial drilling will test the subsurface continuity of lithium-bearing pegmatites and gallium-REE mineralization zones identified through surface sampling and mapping. With multiple anomalies now defined and drill planning underway, Spark's exploration team is preparing to advance its first subsurface testing program within the district.

Quote:"Our ongoing exploration work has clearly delineated key lithium and gallium-rare-earth targets," said Eugene Hodgson, CEO. "The correlations we're observing between lithium and key pathfinder elements, particularly at Cruzeta and Grota do Maquém, provide a strong technical foundation for our first-phase drilling. We're now advancing permitting and logistics to begin as soon as practicable."
