Spark Expands Arapaima's Gallium-Rare Earth Portfolio with Boa Vista Surface Results

Spark Energy Minerals reports high-grade gallium and rare earth element surface sample results from its Boa Vista target at the Arapaima Project in Brazil. Soil samples returned up to 134.4 g/t Ga₂O₃, and stream sediments up to 1.0% TREO, defining a continuous anomalous zone. The results support Boa Vista as a second mineralized center alongside Cruzeta, with historical drilling also confirming near-surface gallium mineralization. The company plans further exploration, including close-spaced soil sampling, rock prospecting, and deeper drilling, but notes that the project remains at an exploration stage with no mineral resource or economic analysis completed.

Atlantico Identifies Strong Gallium Associations With Niobium, Titanium and Vanadium at Flagship Novo Cruzeiro Project

Atlantico Energy Metals Corp. has identified a consistent four-metal pattern of gallium, niobium, titanium, and vanadium across 114 surface samples at its Novo Cruzeiro Project in Brazil. The company reported strong Spearman rank correlations between gallium and these industrial metals, including a high-grade sample containing 72 ppm gallium. However, the results are subject to ongoing laboratory QA/QC clarifications and represent early-stage surface exploration.
