Trigg Minerals Highlights Strategic Tungsten Opportunity at Tennessee Mountain, Nevada

Trigg Minerals has unveiled historical exploration data from its Tennessee Mountain Tungsten Project in Nevada, confirming the presence of high-grade tungsten and outlining the potential for a bulk-tonnage skarn system along the intrusive–carbonate contact.

Key Historical Drilling Results

• 24.9m at 0.65% WO₃ from 7.68m (GH-14), including 10.67m at 0.98% WO₃ from 19.81m and 2.13m at 2.06% WO₃ from 28.35m

• 13.11m at 0.71% WO₃ from surface (GH-08)

• 18.38m at 0.72% WO₃ from surface (GH-09), including 13.17m at 0.91% WO₃ from surface

Most drillholes ended in mineralisation, remaining open at depth and along strike. Importantly, historical sampling was guided by ultraviolet scheelite fluorescence, selectively targeting visible zones and often beginning and ending within mineralised intervals. As a result, reported intercepts likely represent minimum true widths, with broader halos yet to be tested.

Historical trenching also exposed continuous near-surface mineralisation, including a 107m-long, 4.5m-thick tactite bed grading 0.61% WO₃, highlighting the system’s continuity and scale. Tungsten mineralisation has been defined across a strike length exceeding 2.5 km, confirming district-scale potential.

Market Context

The historical work was carried out in 1956 when tungsten traded at ~US$4,000 per tonne. Today, Ammonium Paratungstate (APT), the benchmark tungsten product, trades at around US$42,000 per tonne (Metal.com, August 2025), underscoring the economic significance of the project.

Tungsten – A Strategic Mineral

Tungsten is a critical mineral with unique properties: it is the hardest naturally occurring metal, has the highest melting point of any element, and is irreplaceable in applications such as cutting tools, drill bits, aerospace components, and high-strength alloys. Its strategic importance is most evident in defence, where it is vital for armour-piercing ammunition, artillery shells, missile components, and other military hardware.

China currently controls over 80% of global tungsten production and has recently introduced tighter export restrictions, including bans on certain tungsten products, exacerbating supply chain risks for the United States and its allies. With no active tungsten mines in the U.S., the country is entirely reliant on imports—a clear vulnerability for industries tied to national security.

Strategic Importance of Tennessee Mountain

Located in the Tier-1 mining jurisdiction of Elko County, Nevada, the Tennessee Mountain Project offers the potential to establish a secure domestic U.S. supply of tungsten. By advancing this project, Trigg Minerals is positioning itself as a future supplier of a mineral critical to the defence, aerospace, and industrial sectors, reducing dependence on China and strengthening the resilience of U.S. supply chains.
