[{"type":"text","content":" Vancouver, British Columbia--(Newsfile Corp. - July 28, 2025) - Spark Energy Minerals Inc. (CSE: SPRK) (OTCID: SPARF) (FSE: 8PC) (\"Spark\" or the \"Company\") is rapidly advancing toward a potential lithium discovery at its flagship Arapaima Project in Brazil's Lithium Valley. Ongoing fieldwork has continued to uncover widespread evidence of weathered pegmatite (with remnant quartz-feldspar- tourmaline) veins — the primary geological hosts for lithium in this region. Over 90 samples (surface rock chip and stream sediment) have been collected during the last 5 weeks over areas where tourmaline-bearing quartz gravels and pegmatite veins have been encountered. \"This data will help refine priority diamond drill targets within Spark's already extensive footprint of lithium-targeted pegmatites across Brazil's Lithium Valley. Quartz, Feldspar, and Tourmaline Pegmatite Veins Boost Lithium Exploration Outlook Figure 1: Pegmatite sample featuring quartz, alkali feldspar, and prominent black tourmaline crystals — classic indicators commonly found in lithium-bearing systems. This particular sample (Figure 1) contains: Quartz and alkali feldspar – common building blocks of pegmatite Muscovite – a shiny mica mineral often found in evolved pegmatites Black tourmaline – an important pathfinder mineral for lithium, found scattered throughout the quartz These textures and minerals are exactly what geologists hope to see when hunting for lithium-bearing pegmatites, adding strong support to Spark's evolving geological model and the potential for a widespread lithium system at or close to surface. With multiple outcrops returning similar results, confidence is growing that Arapaima may host a scalable, high-value lithium discovery. \"The geological signatures emerging at Arapaima are highly compelling,\" noted Jon Hill, VP Exploration at Spark Energy Minerals. \"We've mapped multiple pegmatite zones at surface, identified key pathfinder minerals and observed structural features consistent with other known lithium-bearing systems in Brazil's Lithium Valley. The scale and consistency of these indicators point to a potentially evolved pegmatite system, and the upcoming assay results will be key to advancing our drill targeting.\" Figure 2: A roadside rock wall showing light-colored granite with veins runn...
