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

Published: Sep 17, 2025 10:10
Spark Energy Minerals Makes Significant Progress at Arapaima Project in Brazil's Lithium Valley. Through geological mapping, geochemical analysis, and sampling, the company has confirmed priority drill targets for lithium and gallium-rare earth elements (REE). They are advancing logistics, surface access agreements, and permitting to prepare for diamond drilling at the Cruzeta, Água Branca, and Grota do Maquém lithium targets, along with air-core or reverse circulation drilling at the Caladão gallium-REE target. The Arapaima Project has identified 123 pegmatite occurrences over 31 kilometers of strike length, completed reconnaissance and stream sediment sampling over about 55% of the drainage basins, with 75% of sampled basins showing lithium and pathfinder element anomalies needing further follow-up. Surface sampling over a 4,500-hectare area of the Caladão Granite shows anomalous gallium and rare earth element values, adjacent to Axel REE’s recent gallium-REE discovery. Three high-priority lithium targets show strong correlation of lithium with pathfinder elements such as cesium, tin, and rubidium, consistent with fertile lithium-cesium-tantalum (LCT) and spodumene-rich pegmatites (SRP). The association of lithium with manganese and the identification of the mineral lithiophorite suggest lithium remobilization from primary minerals at depth, enhancing the potential for deep lithium mineralization in the area.

Shanxi Kelite to Launch $100M Light Alloy Die-Casting Project in July, Targeting Robotics and EV Markets
[SMM Magnesium Express]Recently, it was reported that Shanxi Kelite Precision Casting Technology Co., Ltd. plans to officially commence production of its light alloy integrated die-casting project in mid-July. With a total investment of 100 million yuan, the project can produce 8 million lightweight robotic precision structural components annually, primarily serving sectors such as meal-delivery robots, household service robots, and new energy vehicles. Leveraging Shanxi's magnesium ore resource advantages, the company has successfully transformed from a traditional pipe-casting enterprise into a high-end precision manufacturing entity. It has introduced cold high-pressure die-casting core technologies and established a provincial-level doctoral entrepreneurship station in collaboration with North University of China. With the project's launch, the large-scale application of magnesium alloy in intelligent robotics and new energy vehicles is expected to deepen further, accelerating the transition of traditional casting enterprises toward high-end magnesium alloy manufacturing.

[SMM Tungsten Analysis] Global Tungsten Markets Diverge in June: China Pulls Back, Europe Holds High
In June, global scrap tungsten markets diverged. India followed China's tungsten price rally, with active trading and higher prices in mid-June before cooling as China softened. Europe saw low-level consolidation due to high speculative inventories, but prices began to edge up in late June as stocks cleared. China's tungsten market experienced a sharp rebound followed by a pullback, and is expected to consolidate in the near term, while medium-to-long-term fundamentals remain solid.
