    Blue Moon Springer tungsten results and land access: key points for mine planners

    Blue Moon Springer tungsten results and land access: key points for mine planners

    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.

    Gold price slides on strong dollar: planning implications for mine projects

    Gold prices slipped to a one-week low as spot gold fell 0.4% to $4,271.16/oz in New York and December futures eased 0.3% to $4,306 amid a stronger US dollar and expectations of more hawkish US Federal Reserve rate moves. The dollar hit a two-month high and US 10-year Treasury yields hovered near a 20-year peak, sharply raising the opportunity cost of holding non-yielding bullion. Oil gained about 1% on stalled US–Iran talks over the war, while spot silver dropped 1.8% to $63.29/oz, platinum 0.2% to $1,746.44, and palladium rose 0.5% to $1,266.40.

    OceanaGold Waihi expansion: design, throughput and tailings notes for engineers

    OceanaGold is weighing a 50% expansion of its Waihi plant to 1.2 Mt/y after Wharekirauponga drilling returned standout intercepts including 6.3 m at 97.2 g/t Au from 481.5 m in the East Graben vein and 8.5 m at 41.5 g/t from 399 m. The move would enable concurrent feed from Martha Underground and Wharekirauponga post‑2032, building on a 2024 plan outlining 1.6 Moz over 15 years and an initial 4.1 Mt reserve at 9.2 g/t. Underground development is advancing, with the Waihi North decline now 350 m, first vent shaft under construction, staged commissioning of a new water treatment plant, and early works on a new tailings storage facility due in Q4.

    Kinross Gold output cut and higher AISC: operational drivers and FCF lens for mine teams

    Kinross Gold has cut its 2026–27 production outlook by about 8% to 1.84–1.86 million attributable gold-equivalent oz. a year and raised 2024 AISC guidance to $1,850–$1,900/oz after winter storms, copper-rich sulphide ore and poor recoveries at La Coipa in Chile, plus weaker mining rates, grades and recoveries at Round Mountain Phase S in Nevada. The company is stockpiling high-copper material, studying a new flotation circuit for deeper sulphide mineralisation that may overlie a copper porphyry system, and using a smaller shovel at Round Mountain to cut dilution. Despite the operational hit and a Q3 output cut to about 425,000 oz., Kinross has lifted its 2026 shareholder return target to 50% of free cash flow and has already returned about $800 million this year, mainly via $655 million in buybacks.
