- Lithium values up to 1,397 ppm discovered at Spark Energy's (SPARF, Financial) Cruzeta target.
- Extensive tenement area of 64,359 hectares in Brazil, identified with 123 pegmatite occurrences.
- High-priority exploration targets include Cruzeta, Agua Branca, Grota do Maquém, and Caladão.
Spark Energy Minerals (SPARF) has announced significant findings at its newly identified Cruzeta target within the Arapaima Lithium Project located in Brazil's renowned Lithium Valley. Rock-chip sampling at the site has revealed lithium concentrations reaching up to 1,397 ppm, marking the highest anomalous lithium values recorded by the company to date. In addition to lithium, the samples have shown notable pathfinder elements including Tantalum, Niobium, Tin, Cesium, and Gallium.
The Cruzeta target displays favorable Potassium/Rubidium (K/Rb) ratios as low as 23.84, indicating the presence of highly evolved and fractionated lithium-cesium-tantalum (LCT) pegmatites. This discovery is part of a broader exploration effort by Spark Energy, which has identified 123 pegmatite occurrences within 13 trends over a 31km strike length across its expansive 64,359-hectare tenement package.
The company has mapped three primary lithium exploration targets: Agua Branca, Grota do Maquém, and Cruzeta, along with a rare earth elements target, Caladão, all of which are prioritized for detailed exploration. These initiatives are part of Spark Energy's strategic efforts to capitalize on the resource-rich area, which is globally recognized for its potential in lithium and rare earth mineral deposits.
Despite the promising results, the exploration program at Cruzeta and other targets remains in its early stages, with no drilling results yet released. Additional exploration activities are required to fully assess the economic viability of these deposits. Spark Energy continues to advance its reconnaissance phase across the project area, focusing on generating high-quality drilling targets.
