Spartan Metals (TSXV:W) – Reviving America’s Lost Tungsten Supply Chain

Interview with Brett Marsh, President & CEO of Spartan Metals

Recording date: 16th October 2025

Spartan Metals Corp has emerged as a focused player in the critical minerals sector with its Eagle project in Nevada, a past-producing district that encompasses two historic tungsten mines and a high-grade copper-silver operation. The company's strategic approach centers on reviving domestic tungsten production at a time when the United States faces near-total import dependence for this defense-critical metal.

CEO Brett Marsh, bringing 25 years of geology experience across major mining companies and junior explorers, has deliberately structured Spartan around tungsten development despite the presence of valuable polymetallic mineralization on the property. The company's stock symbol 'W' reflects this unwavering focus on what Marsh describes as the cornerstone commodity driving the venture.

The Tungstonia deposit presents compelling characteristics for modern exploration. Historic mining during World War II and earlier periods produced grades between 0.6% and 0.9% tungsten trioxide, with operations extending only to approximately 75 meters depth. Recent work reveals that veins mined over 700 meters of strike length actually extend to nearly 2 kilometers, suggesting substantial depth potential that previous operators never tested.

An immediate catalyst exists in the form of 10,000 tons of historic tailings grading 0.15% tungsten trioxide. Drilling commenced October 20th to establish tonnage, grade distribution, and metallurgical characteristics, with Marsh indicating the company will likely partner with entities possessing downstream processing capability for monetization rather than developing standalone infrastructure.

Spartan's recent $2.25 million financing fully funds a comprehensive Phase 1 exploration program including surface mapping, soil geochemistry, geophysical surveys, and 3D geological modeling ahead of maiden drilling tentatively scheduled for early spring 2026. The company's systematic approach to validating century-old data through modern exploration techniques has attracted attention from both investors and government entities interested in reshoring strategic mineral supply chains. With tungsten classified as critical by the U.S. government and China controlling approximately 80% of global supply, Spartan's timing aligns with heightened policy support for domestic production alternatives.
