Tungsten Mining has secured the primary approvals needed to take its Watershed tungsten project in Far North Queensland through to mining and production, while early site works are already under way. The project remains pre-FID, with financing and the October DFS still critical to the H1 2027 production target.
- Primary environmental, heritage and rehabilitation approvals secured
- Up to 60 people now working on site
- Early access, clearing, drilling and camp works under way
- DFS targeted for October 2026 and FID for late 2026
- June PEE estimated A$1.31 billion pre-tax NPV8 and 198% IRR
Watershed Clears Main Regulatory Hurdle
Tungsten Mining NL (ASX:TGN; OTCQB:TGNMF) has reached a significant development milestone at its 100%-owned Watershed Tungsten Project, announcing that the Far North Queensland operation now has its primary approvals for mining and production. The approvals include an Environmental Authority, a Progressive Rehabilitation and Closure Plan, an Indigenous Land Use Agreement with Western Yalanji Aboriginal Corporation and an EPBC Act determination that the project is not a controlled action in the particular manner specified.
The company also has a Cultural Heritage Management Plan in place, although heritage surveys continue, while its environmental rehabilitation security has been lodged and approved. Tungsten Mining chairman Gary Lyons said the approvals allowed site works and camp construction to proceed as the company advances towards a Definitive Feasibility Study and Final Investment Decision. “With our full Environmental Authority and PRCP approved on granted Mining leases, Watershed is now fully permitted through to construction and operations,” Lyons said.
Early Construction Work Expands Across Site
Physical activity is no longer confined to exploration. Up to 60 people are currently on site across resource drilling, exploration, water-bore and geotechnical drilling, environmental and heritage surveys, and general site establishment.
Access-road construction and approved clearing are progressing around the proposed process plant, accommodation facilities and early mining areas. Tungsten Mining is also preparing camp modules and expanding accommodation for more than 100 personnel by the end of September and more than 200 by the end of November, although the immediate facilities are being prepared to support up to 120 people.
Construction Commitment Still Depends on FID and Funding
The early works are designed to establish access and working areas and reduce activities on the critical path after FID. They do not amount to a final construction commitment: the company expressly says full project construction remains subject to FID, financing and other project conditions.
That distinction matters because Watershed’s headline economics come from the June 2026 Preliminary Economic Evaluation rather than a new study in this announcement. The PEE outlined a 69.7 million-tonne mineral resource grading 0.11% WO3, a potential eight-year mine life, pre-production capital of A$274 million, a pre-tax NPV8 of A$1.31 billion and a pre-tax IRR of 198%. The production target is partly based on Inferred Mineral Resources, which carries a low level of geological confidence and may change as drilling and engineering work progress.
DFS and Financing Become the Next Tests
Tungsten Mining is targeting delivery of the DFS in October 2026, followed by an FID in late 2026 and first production in the first half of 2027. Those dates remain targets rather than guarantees: the company flags the need to complete remaining studies, secure project financing and satisfy other project conditions before the schedule can be treated as firm.
Bottom Line?
Approvals have moved Watershed into visible site execution, but the investment case now turns on the October DFS, financing package and whether FID can follow on schedule.
Questions in the middle?
- Will the October DFS preserve the PEE’s A$274 million capital estimate and unusually high return metrics?
- What financing structure will support construction after early works are complete?
- Can drilling and further engineering convert the project’s inferred-resource exposure into a firmer production case?
