Spark Energy Minerals Validates Priority Lithium and Gallium-REE Drill Targets at Arapaima Project in Brazil's Lithium Valley

Core Insights - Spark Energy Minerals Inc. has made significant progress at its Arapaima Project in Brazil's Lithium Valley, confirming high-priority lithium and gallium-rare earth element (REE) drill targets through recent exploration work [2][5][6] Exploration Progress - The company is advancing logistics, surface access agreements, and permitting for aggressive diamond drilling at three lithium targets: Cruzeta, Água Branca, and Grota do Maquém, as well as air-core and/or reverse circulation drilling at the emerging gallium-REE Caladão Target [3][6] - Exploration activities have identified three high-priority lithium targets where lithium is strongly correlated with pathfinder elements such as cesium, tin, and rubidium, typical of fertile lithium-cesium-tantalum pegmatites [6][9] - Surface sampling has outlined a 4,500-hectare zone over the Caladão Granite with anomalous gallium and REE values, adjacent to Axel REE's recently reported discovery [9][29] Geochemical Analysis - Lithium shows a strong association with manganese and has been remobilized from primary sources, indicating potential for lithium mineralization at depth [7][11] - Recent rock-chip samples from the Cruzeta target have returned cesium values above 50 ppm, with some reaching 267 ppm, reinforcing the focus on these targets [17][19] - All three priority targets returned K/Rb ratios under 150, with Cruzeta showing a notably low ratio below 20, indicating strong lithium prospectivity [25][27] Future Plans - The exploration team is preparing logistics and permitting to begin drilling at priority lithium and rare earth targets, marking a transformative step toward unlocking the full potential of the Arapaima Project [33]
