Guardian Metal Resources (OTCQB:GMTLF) has announced exceptional assay results from its 100%-owned Pilot North tungsten-copper project in Nevada. The company collected 92 rock chip samples from the recently staked 102 BLM Lode Claims, revealing significant mineral concentrations including copper grades up to 14.65%, silver up to 708 g/t, and tungsten trioxide up to 0.59%.
The Project, located 15km northwest of the company's Pilot Mountain project, encompasses five historical World War II-era mines: Copper Head, Western Metals, Muller Mountain, Jasper, and Tungsten Valley. The geology mirrors that of Pilot Mountain, with tungsten-copper bearing skarns at granitic intrusion contacts.
This strategic acquisition aligns with Guardian Metal's mission to establish itself as a cornerstone of U.S. tungsten supply, supporting national efforts to reduce foreign supply chain dependence for this critical defense mineral.
