Tungsten Mining Unveils Massive New Target at Mulgine Trench

Expanding the Mulgine Trench Footprint

Tungsten Mining NL has revealed a substantial new Exploration Target at its Mulgine Trench deposit, part of the broader Mt Mulgine critical minerals project in Western Australia. This target, estimated between 165 and 200 million tonnes grading 0.10–0.12% tungsten trioxide (WO3) and 180–220 parts per million molybdenum (Mo), sits atop the already impressive 2020 Mineral Resource estimate of 247 million tonnes. The announcement underscores the growing scale and continuity of mineralisation at Mulgine Trench, reinforcing its position as a globally significant source of critical metals.

Robust Continuity and Open Mineralisation

The deposit has been delineated by a dense drilling pattern spaced at 40 metres, covering 1.5 kilometres of strike and extending to depths of 250 metres, with mineralisation remaining open both down dip and to the south. This continuity is a key factor in the company’s confidence that the project can support an extended mine life and potentially larger-scale production. The mineralisation is associated with scheelite and molybdenite within a complex geological setting involving hydrothermal alteration of granitic and greenstone sequences.

Strategic Importance of Tungsten and Molybdenum

Tungsten is a critical metal with limited global supply and strategic importance across aerospace, defense, electronics, and industrial sectors. Molybdenum, often found alongside tungsten, enhances the value proposition of the deposit. Tungsten Mining’s Chairman, Gary Lyons, emphasised the metal’s supply constraints and the project’s role in global critical mineral supply chains. The company aims to complete a Pre-Feasibility Study by mid-2026, supported by planned drilling to further define mineralisation and support project development.

Next Steps and Market Implications

Supplementary drilling is scheduled for the first half of 2026 to confirm mineral continuity beneath the current resource and to explore extensions that could increase the mine life. This work will be crucial in upgrading the Exploration Target to a Mineral Resource under the JORC Code, a necessary step before advancing to full feasibility and potential production. Given the strategic nature of tungsten and molybdenum, the project’s advancement could have meaningful implications for supply security in critical minerals markets.

Balancing Optimism with Caution

While the Exploration Target highlights significant potential, it remains conceptual until further drilling confirms resource status. Investors and analysts will be watching closely for the results of upcoming drilling campaigns and the Pre-Feasibility Study outcomes. The project’s tenure is secure, and historical drilling data has been rigorously reviewed, lending confidence to the company’s technical foundation.
