What is happening with Tungsten Mining?

Tungsten Mining is developing the Watershed tungsten project located approximately 130 kilometres north of Cairns, Queensland.

The company is focused on progressing the project through resource definition and exploration activities, with tungsten considered a strategically important mineral due to its industrial applications.

Recent activity has centred on an updated Mineral Resource Estimate and a major reverse-circulation drilling programme designed to improve understanding of the deposit.

Latest company developments

The updated Watershed Mineral Resource Estimate announced in June 2026 increased the project resource to 69.7 million tonnes at 0.109% tungsten trioxide (WO3).

The updated estimate represents approximately 76,000 tonnes of contained WO3 metal, an 8% increase compared with the previous estimate.

The company also revised the resource cut-off grade from 0.05% WO3 to 0.04% WO3, reflecting the assessment of lower-grade material under current market conditions.

The resource extends approximately 1.2 kilometres along strike and between 250 and 500 metres across strike, covering multiple mineralisation styles and remaining open at depth and along strike.

In August 2026, Tungsten Mining commenced a 15,000-metre reverse-circulation drilling programme at Watershed.

The programme is designed to infill existing areas of mineralisation and test resource continuity using drilling spacing of approximately 20 to 30 metres.

The company is also progressing other projects, including Hatches Creek in the Northern Territory and Mt Mulgine in Western Australia, which provides exposure to both tungsten and gold opportunities.

What do the numbers say?

For Tungsten Mining, the key measures are resource scale, tungsten grade and exploration progress rather than current earnings.

The Watershed resource of 69.7 million tonnes at 0.109% WO3 represents approximately 76,000 tonnes of contained tungsten metal and remains the central focus of the company’s development strategy.

The increase in contained metal highlights progress in resource definition, while the lower cut-off grade expands the reported resource base under current tungsten market assumptions.

The ongoing 15,000-metre drilling programme is aimed at improving confidence in the resource and potentially identifying additional mineralisation.

As a pre-production developer, the company does not currently generate operating revenue, meaning future value depends on technical studies, project economics, funding capacity and development decisions.

The company’s current financial position and funding runway remain important factors for investors to monitor through its latest company filings.

What could drive the shares from here?

Drilling results from the Watershed programme remain the most immediate potential driver for Tungsten Mining (ASX:TGN).

Successful results demonstrating consistent grades, mineralisation continuity or further resource growth could strengthen the development case.

Progress towards future technical studies and potential development assessments would represent an important step in moving the project closer to a production pathway.

Advancement of Mt Mulgine and other tungsten opportunities may provide additional project exposure.

Broader tungsten market conditions and Demand for alternative critical mineral supply sources could continue influencing investor sentiment towards the sector.

Risks investors should watch

Tungsten Mining remains a pre-production developer and is exposed to exploration and development risks.

Drilling results may not deliver expected resource growth, and future technical studies may identify challenges related to project economics.

The reduction in cut-off grade increases resource tonnes but also makes project viability more dependent on sustained tungsten prices.

Funding remains an important consideration, as progressing exploration and development activities may require additional capital.

As a small-cap resources company, Tungsten Mining’s share price may also be influenced by Commodity sentiment and limited market liquidity.

Investor takeaway

Tungsten Mining (ASX:TGN) continues advancing the Watershed tungsten project, supported by an expanded resource base and ongoing drilling activities.

The company’s updated resource of 69.7 million tonnes containing approximately 76,000 tonnes of WO3 and the current 15,000-metre drilling programme provide key development milestones.

However, the company remains at the development stage, with future value dependent on exploration success, tungsten market conditions, funding and progress towards a potential production pathway.
