Western Star Resources Inc. (CSE: WSR) (OTC: WSRIF) (FRA: 4K2) has mobilized field crews to its 100% owned White Star Tungsten Project in Elko County, Nevada, to conduct the first modern exploration program on the property, which surrounds the past-producing Mission Cross Mine. The company announced the mobilization on June 22, 2026, as the United States faces a January 1, 2027 federal procurement rule that will bar tungsten sourced from China, Russia, Iran, and North Korea from a wide range of defense applications.
Drone Geophysics and Soil Sampling Underway
The initial work consists of a property-wide, high-resolution UAV (drone) magnetic survey combined with a systematic soil-geochemistry program. This foundational fieldwork aims to transform the historic mine site into a set of modern, drill-ready targets. The White Star project sits directly adjacent to Western Star's own Rowland Tungsten Property in the Charleston Mining District, one of America's most historically significant tungsten districts.
"We are thrilled to have crews on the ground at White Star, advancing this project in a critical time for U.S. tungsten supply," said a Western Star spokesperson. "This exploration program is the first step toward developing a domestic source of tungsten that meets national security needs."
Structural Repricing of Tungsten
The urgency is underscored by dramatic tungsten price movements. The Rotterdam ammonium paratungstate (APT) benchmark has traded around US$3,000–$3,200 per metric tonne unit through mid-2026, after surging roughly 350% over the course of this year and approximately 900% from 2025 lows. APT was below US$250/mtu as recently as 2020. According to industry analysts, this is not a typical industrial-metal wobble but a structural repricing of supply risk.
China controls roughly 80% of global tungsten mine supply and dominates the downstream chain converting ore into APT, powder, and carbide. Beijing tightened export licensing on tungsten starting in 2023, and the squeeze intensified through 2025: exports of key processed tungsten products fell sharply. In December 2025, China confirmed that only 15 companies would be authorized to export tungsten in 2026–27, giving the state direct control over volume, timing, and destination. China's own mined output is estimated to have fallen around 10% year-over-year in 2025 as aging mines and declining ore grades take their toll.
Demand Growth and the Procurement Cliff
Tungsten consumption is forecast to climb meaningfully through the next decade, driven by defense, aerospace, semiconductors, and industrial carbide, and increasingly by artificial-intelligence infrastructure, where tungsten compounds are used in advanced semiconductor manufacturing. The January 1, 2027 prohibition gives Western prime contractors a fixed date by which they need documented, non-Chinese tungsten for defense work. For a U.S.-based project, "domestic" and "near-term" are exactly the adjectives that matter.
Western Star is positioning itself to fill that gap. The company's White Star and Rowland properties represent a rare opportunity to restart domestic tungsten production in a district that once supplied significant tonnage. With drone geophysics underway and three U.S. tungsten projects active in 2026, Western Star is racing the defense-procurement clock.
