Tungsten Mining Advances Mt Mulgine Drilling Program

13 May 2026 | Western Australia - Tungsten Mining NL has commenced on-site preparation works at its 100%-owned Mt Mulgine Project in Western Australia, ahead of a major RC and diamond drilling program at the Mulgine Trench deposit.

The company said current site activities include drill pad preparation, surveying, drill hole mark-out, support infrastructure groundworks, site access preparation and safety work required before drilling can begin.

The planned RC drilling campaign will include 130 holes for 40,000 metres at Mulgine Trench. The program is designed to test the continuity of extensions beneath the 2020 Mineral Resource Estimate, targeting an additional 80 metres to 160 metres down-dip. Assay results are expected to be released periodically, approximately six weeks after drilling commences.

Tungsten Mining is also planning 37 PQ diamond holes for 4,700 metres to collect material for metallurgical test work and obtain geotechnical data for future pit designs.

The drilling will test the upper portions of the previously reported Exploration Target at Mulgine Trench, which is estimated at 165 to 200 million tonnes at 0.10% to 0.12% WO3 and 180 to 220 ppm molybdenum, for 165,000 to 240,000 tonnes of contained WO3 and 30,000 to 36,000 tonnes of contained molybdenum. This is in addition to the existing 2020 Indicated and Inferred MRE at Mulgine Trench.

Tungsten Mining Chairman Gary Lyons said the commencement of on-site preparations represented an important operational milestone as the company progresses toward drilling at Mulgine Trench. He said the potential exists, subject to drilling and assessment, to add to TGN’s already significant resource base and potentially position Mt Mulgine as the largest tungsten project in the world.

Why it matters: Tungsten is a critical mineral used across defence, aerospace, electronics, automotive, mining, construction and industrial applications. Tungsten Mining describes tungsten as strategically important due to its high melting point, high-temperature mechanical properties and use in cemented carbides, high-speed steels, super alloys, tungsten mill products and chemicals.

The Mt Mulgine Project is located approximately 330 kilometres north-northeast of Perth and 15 kilometres northeast of Rothsay. The project includes the Mulgine Hill and Mulgine Trench deposits, with Tungsten Mining holding title and mineral rights across the project tenements.

For Western Australia’s mining sector, the program is another sign of growing momentum around critical minerals projects, particularly those with the potential to support future supply chains outside traditional global sources.

Tungsten Mining said the Exploration Target remains conceptual in nature, with insufficient exploration completed to estimate a Mineral Resource for that target at this stage. The company will continue to update the market on drill rig mobilisation and assay results as material information becomes available.
