Spartan Metals announced the confirmation of two tungsten skarn zones at the Tungstonia claims within its wholly owned Eagle Project in Nevada, US. As part of its ongoing exploration programme launched in May 2026, rock sampling from the historic Yellow Jacket Mine within the project returned tungsten trioxide grades ranging from 0.89% to 1.87%. Crucially, assays from the mine entrance and dumps detected notable concentrations of zinc (up to 3.3%) and 1,320 ppm beryllium, the latter being a newly discovered critical metal at the property. Backpack core drilling at the mine also intercepted a 0.3-meter interval grading 0.21% tungsten trioxide and 0.33% zinc. The confirmed mineralization, spanning an estimated 2-kilometer area, hosts a complex system of tungsten, molybdenum, beryllium, rubidium, and silver. Spartan Metals intends to launch approximately 3,000 meters of diamond core drilling at selected targets from early to mid-August to further untangle this expanding mineralized system.

Storm High-Grade Copper PFS Slated for Q3, Regional Targets Return High-Grade Zinc up to 30.8%

American West Metals reported that the Pre-Feasibility Study (PFS) for its high-grade Storm project in Nunavut, Canada, is slated for completion in Q3 2026, which will detail the parameters of a direct shipping ore (DSO) operation. Since the completion of the PEA last March, JORC-compliant resources have expanded by over 20% to 28.22 million tonnes, containing 608.7 million lbs of copper and 2.97 million oz of silver. While finalizing the PFS and advancing mine permitting, American West is expanding its exploration scope across the 110-kilometer-long belt of high-grade sediment-hosted copper and zinc mineralization. Notably, the Tempest target, located 40 kilometers south of the main Storm area, is defined by a 4-kilometer zone of surface gossans where grab samples have returned extraordinary grades of up to 30.8% zinc and 38.2% copper, highlighting the district's significant polymetallic potential.
