Great Western Mining Uncovers High-Potential Tungsten Resource in Nevada

Great Western Mining Corporation PLC announced positive tungsten assay results from its Defender-Pine Crow project in Mineral County, Nevada, in January 2026 and July 2026. These results significantly upgraded the tungsten potential of the area. The company confirmed significant tungsten mineralization at the Defender site, a critical metal for defense and industrial use.

Great Western Mining completed machine-cut channel sampling at the Defender-Pine Crow project in December 2025 and April 2026. The December 2025 sampling at Defender yielded encouraging results. Channel A intercepted 6 meters (20 feet) at 0.17% tungsten trioxide (WO3), including 1 meter (3 feet) at 0.43% WO3. Channel B showed 16 meters (52 feet) at 0.30% WO3, with a 2-meter (7-foot) section at 0.66% WO3. These samples also contained very low concentrations of penalty elements that could hinder WO3 processing, such as molybdenum and lead. Silver mineralization was also identified in Channel B, with 2 meters at 2.95 grams per tonne (g/t) silver in garnet skarn and 3 meters at 1.55 g/t silver in granite.

Further sampling in April 2026 at the Defender-Pine Crow project confirmed additional significant mineralization. Channel C intercepted 27 meters at 0.15% WO3, including 11 meters at 0.25% WO3. Channel D returned 5 meters at 0.12% WO3, while Channel E showed 3 meters at 0.34% WO3. Channel F intercepted 18 meters at 0.15% WO3, including 6 meters at 0.22% WO3. Channel F also revealed silver mineralization across two 2-meter intervals, at 17.6 g/t and 10.1 g/t silver.

The Defender and Pine Crow tungsten skarns, historically productive during World War II, are approximately 2 kilometers northeast of the company's M2 skarn copper resource. These skarns are at the contact zones of Cretaceous granitic intrusions with limestones of the Jurassic Dunlap Formation. Field mapping and grab sampling in June 2025 confirmed scheelite-bearing skarns at both Defender and Pine Crow, with rock chip samples recording up to 1.75% WO3. Previous sampling had shown lower grades, with a maximum of 0.33% WO3. The company expanded its claims around these former mine sites in late 2024. Soil sample geochemistry in October 2025 indicated elevated tungsten, copper, and zinc for at least 1.4 kilometers along strike.

Tungsten is a critical metal for defense and industrial applications, currently experiencing short supply in Western markets. China controls 80% of global tungsten production and 97% of global processing capabilities. Spot tungsten prices (ammonium paratungstate, APT) recently reached 12-year highs of approximately $400 per metric tonne unit, driven by Chinese export restrictions. The United States has officially declared tungsten a critical mineral. Great Western Mining's confirmation of significant tungsten mineralization in Nevada aligns with the U.S. demand for secure domestic supplies of critical and strategic minerals. The company plans further exploration, including drilling, to advance the project.

Impact on Prices of Chemical Commodities Tracked by ChemAnalyst

The immediate impact on tungsten-related chemical commodities tracked by ChemAnalyst, particularly Ammonium Paratungstate (APT) and Tungsten Trioxide (WO3), is expected to be limited in the short term because the Defender-Pine Crow project remains in the exploration stage. However, the announcement is bearish for long-term price expectations, as it signals the potential emergence of an additional domestic tungsten supply source in the United States. Current tungsten prices remain elevated due to Chinese export restrictions and constrained global supply, so near-term market fundamentals are unlikely to change. As the project progresses through drilling, resource estimation, and eventual production, expectations of increased Western supply could gradually ease market concerns and moderate future price increases. Downstream tungsten-based chemicals and materials used in cemented carbides, catalysts, specialty alloys, and defense applications may also benefit from improved supply security, although meaningful price effects will depend on successful project development and production timelines.
