    Aris’ US$80M Soto Norte acquisition: project scale and schedule for mine planners

    Aris’ US$80M Soto Norte acquisition: project scale and schedule for mine planners

    First reported on MINING.com

    30 Second Briefing

    Aris Mining will pay US$80 million to acquire full ownership of the Soto Norte gold project in Colombia, positioning the company to target production of around 1 million oz of gold per year. The deal consolidates Aris’s interest in one of the country’s largest undeveloped underground gold assets, located in Santander department near the historic California-Vetas mining district. For mine planners and investors, the transaction signals intent to advance a large-scale, long-life operation in a jurisdiction already hosting significant high-grade underground gold mining.

    Technical Brief

    • Full ownership simplifies future project financing, removing joint-venture decision constraints and misaligned capital schedules.
    • Consolidation allows a single mine plan and LOM schedule, rather than parallel partner development scenarios.
    • Aris indicated it will update the Soto Norte technical study and project economics post-acquisition.

    Our Take

    With gold one of the few repeated keywords in our recent mining coverage, Aris consolidating 100% of Soto Norte signals a push to secure long-life gold optionality at a time when peers like Ivanhoe Mines are commissioning multi-metal assets such as Platreef.

    An $80M M&A outlay for a single gold project positions Aris at the smaller end of recent capital moves in our database, which may give it more flexibility to stage development or adjust to permitting and ESG conditions compared with the multi‑billion‑dollar builds now common in diversified portfolios.

    Among the 53 tag-matched ‘Projects’ and ‘Contract Award’ pieces, relatively few involve outright buyouts for gold assets, suggesting Aris is opting for ownership control rather than the JV-heavy or streaming-heavy structures seen in many current gold project financings.

    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.
