US $500m cobalt tender reopened: strategic supply signals for mine planners

First reported on MINING.com

30 Second Briefing

The US Defense Logistics Agency has reopened a $500 million tender to buy up to 7,500 tonnes of cobalt after benchmark prices more than tripled since mid-August. The agency first sought offers in August but is now reissuing the procurement as spot market volatility and tight supply complicate long-term contracting. For miners and refiners, the move signals sustained US strategic demand for cobalt metal and intermediates, with potential upside for projects able to deliver secure, traceable supply into government stockpiles.

Technical Brief

  • Traceability and origin disclosure provisions will favour projects with established ESG and chain‑of‑custody systems.
  • Price volatility since August complicates fixed‑price offers, pushing bidders towards index‑linked or formula pricing.
  • For mine developers, the tender creates an offtake anchor that can support project financing assumptions.

Our Take

Cobalt appears in only a handful of pieces in our mining coverage, so a US-based $500m Defence Logistics Agency tender signals that strategic stockpiling rather than pure market supply stories is currently driving most cobalt-related activity.

For United States items tagged as Projects and Contract Award, tenders of this scale are more commonly associated with defence or critical minerals security than with single-mine development, suggesting downstream processors and recyclers may be as relevant as primary miners in bidding dynamics.

With a mid-August time horizon, the reopened cobalt tender effectively sets a near-term price and volume signal for US-linked offtake, which is likely to influence contract negotiations for North American cobalt projects and refiners captured elsewhere in our mining database.

Central Nevada Gold’s Mule Canyon acquisition: project and risk lens for engineers

Central Nevada Gold has completed a US$20 million acquisition of Newmont’s past‑producing Mule Canyon mine in Nevada, targeting a prefeasibility study and key permits in H2 2027 ahead of a potential 2028 construction decision. Mule Canyon previously produced about 500,000 oz gold at an average head grade of 3.8 g/t with ~94% metallurgical recovery, and comes with a database of 2,149 drill holes totalling over 335,000 metres across six mineralised zones over 2.5 km. The company plans an IPO as early as 2027 after a 20‑hole metallurgical and infill drilling programme to upgrade inferred resources and de‑risk the project.

Greenland Mines’ Sarfartoq licence: key project and offtake notes for mine planners

Greenland Mines has secured government approval under the Greenland Mineral Activities Act for the indirect transfer of the Sarfartoq carbonatite complex exploration licence, clearing a key condition in its US$35 million acquisition from Neo Performance Materials, which retains offtake rights to up to 60% of future ore or concentrate. The Nd-Pr-enriched project, about 60 km from Kangerlussuaq, carries a historic NI 43-101 resource with 5.88 Mt indicated at 1.77% TREO and 2.46 Mt inferred at 1.59% TREO, based on 23,000 m of drilling. The news sent Greenland Mines’ NASDAQ-listed shares up more than 22%, giving the company a market capitalisation of US$31.4 million.

Silver price 20% August surge: leverage, scenarios and risks for mine planners

Silver surged about 20% in August to touch $70/oz on 21 August, driven by the US Treasury’s move to double long-bond buybacks, pushing prices above several banks’ 2026 baseline forecasts but still below the most bullish $110–$160/oz year-end and Q4 targets. Equity leverage has been stark: Hecla Mining gained 47%, Wheaton Precious Metals 44%, and Coeur, First Majestic and Fortuna each 42%, while the Global X Silver Miners ETF rose 35% and junior-focused SILJ 32%. Forecasts now span roughly $67–$118/oz for peaks, with tail-risk scenarios from Bank of America and BMO stretching above $135/oz if the gold–silver ratio compresses.
