Tungsten Mining’s Watershed fully permitted: schedule and closure lens for engineers
Reviewed by Joe Ashwell
First reported on Australian Mining
30 Second Briefing
Tungsten Mining’s Watershed project in Far North Queensland is now fully permitted for mining and production, with all primary approvals secured, including its Environmental Authority and Progressive Rehabilitation and Closure Plan. The company is targeting a final investment decision later in 2026 on the 100 per cent-owned tungsten deposit, which is positioned as a long-life open-pit operation. Full permitting de-risks project scheduling for mine development, tailings and waste landforms, and staged rehabilitation, giving contractors and financiers clearer visibility on execution and closure obligations.
Technical Brief
- Environmental Authority and PRCP approvals lock in defined conditions for waste rock and tailings landforms.
- Full permitting sequence clarifies sequencing of open-pit development, waste placement and progressive rehabilitation campaigns.
- Regulatory sign-off enables early contractor engagement on mine earthworks, haul roads and TSF construction methodologies.
- Approvals framework provides fixed closure criteria, influencing slope design, cover systems and water management layouts.
- Clear permitting envelope reduces risk of redesign for haulage alignments, stockpile footprints and ancillary infrastructure.
- Finance discussions can now reference a stable approvals regime, tightening contingencies for schedule and closure liabilities.
Our Take
With Watershed in Far North Queensland now fully permitted and 100 per cent owned, Tungsten Mining is effectively running a dual-asset build-out alongside Mt Mulgine in Western Australia, which our database shows is already in on-site preparation; this spreads development risk but will stretch project delivery capacity.
The earlier engagement of Cutfield Freeman & Co to structure funding for Watershed suggests this permitting milestone is likely timed to support a near-term final investment decision, giving lenders and potential offtakers in the tungsten space clearer line of sight on approvals risk in Queensland.
Being listed in the Australian Critical Minerals Prospectus and having raised $53 million for its tungsten pipeline positions Tungsten Mining as one of the more active tungsten developers in our recent Mining coverage, which may give it an edge in securing downstream partnerships as Australia sharpens its critical minerals strategy.
