Blue Moon Springer tungsten results and land access: key points for mine planners
Reviewed by Joe Ashwell

First reported on MINING.com
30 Second Briefing
Blue Moon Metals’ Springer project in Nevada returned a 7 metre interval grading 1.28% WO₃ and 0.01% Mo from 160 metres in surface hole NM-13, plus 24.25 metres at 0.53% WO₃ and 0.12% Mo in NM-44, from a relogging and re-assay campaign now 64% through 18,000 metres of historical core. The 4,560-hectare skarn project, with a historical 355,000 tons at 0.537% WO₃ and a 1,200 long ton/day mill built by General Electric, is being evaluated for restart in Q4 2027. US BLM approval for 13 new drill pads enables a planned 67,000-metre diamond drilling programme on public land, materially expanding step-out and infill options.
Technical Brief
- Historical sampling covered only ~5% of core and assayed tungsten only, leaving other metals unconstrained.
- Re-logging and re-assay of 18,000 metres of legacy core is 64% complete, materially upgrading data density.
- Broader sampling strategy is targeting mineralisation previously excluded by selective historical assaying protocols.
- Springer’s underground mine and vertical shaft, built by General Electric in the 1970s, provide brownfield access.
- Existing mill is rated at ~1,200 long tons per day, offering substantial installed processing capacity for restart.
- Historical indicated resource stands at 355,000 tons grading 0.537% WO₃, providing a baseline for current work.
- Production history is limited: mine and mill operated only from March to October 1982 before shutdown.
- BLM approval for 13 drill pads on public land is a prerequisite for the 67,000‑metre diamond drilling campaign.
Our Take
The reported 1.28% and 0.53% WO₃ intervals at the Springer project line up with the historical indicated grade of 0.537% WO₃, which suggests the relogging campaign (64% reported so far) is more about expanding and de‑risking the resource base than chasing a step-change in grade profile.
In our database, Blue Moon Metals’ Springer tungsten work in Nevada sits alongside the US Department of War’s planned US$150 million investment into the same complex, indicating these drill results and new BLM access could directly influence timing and scope of that downstream funding package.
Blue Moon’s growing tungsten footprint in the western USA, including the 4,560-hectare Springer project and its separate acquisition of 33 tungsten–antimony properties on BLM and Forest Service lands, positions it as one of the more aggressive tungsten consolidators in our recent Mining coverage despite its parallel copper focus at Nussir in Norway.
