    Lundin’s $84M Eagle mine sale to Talon: asset and processing lens for mine planners

    Lundin’s $84M Eagle mine sale to Talon: asset and processing lens for mine planners

    First reported on MINING.com

    30 Second Briefing

    Lundin Mining is selling its Eagle nickel-copper underground mine and Humboldt Mill in Michigan to Talon Metals in an all-share deal worth about $84 million, giving Lundin roughly 275 million Talon shares and a 20% non-diluted stake. Eagle, the only primary nickel mine currently operating in the US, has produced over 194,000 tonnes of nickel and 185,000 tonnes of copper, generating more than $3.2 billion in revenue to Q3 2025. Talon plans to use Humboldt Mill as a centralised processing hub while advancing the Tamarack project in Minnesota and a Beulah processing facility in North Dakota.

    Technical Brief

    • Transaction structured as transfer of Lundin’s entire US subsidiary owning Eagle and Humboldt Mill.
    • Consideration is ~275 million Talon shares, priced at about $83.7 million on recent trading.
    • Post-closing, Lundin retains a 20% non‑diluted equity position in Talon for ongoing exposure.
    • Humboldt Mill explicitly earmarked as a shared, centralised processing hub for multiple Talon feed sources.
    • Talon board to expand to 10 directors, with two Lundin nominees embedded in post‑deal governance.
    • Current Eagle/Humboldt managing director, Darby Stacey, to become Talon CEO, aiding operational continuity.
    • Integration plan prioritises four parallel workstreams: Eagle life extension, Michigan/Minnesota exploration, Tamarack permitting, and Beulah feasibility.

    Our Take

    Lundin Mining’s move to take a 20% non‑diluted stake in Talon Metals aligns with our database pattern of mid-tier copper producers recycling capital from mature North American assets into higher-growth copper districts such as Candelaria, Chapada and the Vicuña cluster (Josemaría, Filo del Sol).

    For Talon, folding the Eagle nickel-copper mine and Humboldt Mill into a portfolio that already includes the Tamarack Nickel-Copper Project and the planned Beulah Minerals Processing Facility suggests a strategy to control both upstream ore and downstream processing capacity in the US Midwest, which can be attractive for North American battery supply chains.

    Among the 110 keyword-matched copper and nickel pieces in our coverage, very few M&A deals involve assets that have already generated over $3 billion in cumulative revenue, signalling that Eagle is being transferred as a de-risked cash-flowing operation rather than a typical development-stage acquisition.

    Ioneer partner search to H1 2026: Rhyolite Ridge economics for mine planners

    Ioneer now expects to secure a new partner for its Rhyolite Ridge lithium-boron project in Nevada in H1 2026, after Sibanye-Stillwater withdrew from a proposed $490 million, 50% stake and Goldman Sachs-advised talks overran the original four‑month timetable amid weaker markets and geopolitical uncertainty. Backed by a $996 million US government loan and all key permits, Rhyolite Ridge has an updated DFS with a 95‑year mine life, NPV lifted to $1.5 billion, and reserves of 7.8 Mt boric acid plus 2 Mt lithium carbonate supporting an initial 77‑year plan. Average output for years 1–25 is now projected at 24,500 t/y lithium carbonate equivalent and 135,500 t/y boric acid, placing the operation in the global lowest cost quartile on an LCE basis and making co‑product economics central to any JV valuation.

    Graphite One $2.1bn EXIM loan: capex, schedule and risk notes for mine planners

    US Export-Import Bank has lifted potential financing for Graphite One’s Alaska-to-Ohio graphite supply chain to about $2.1 billion, including $670 million for the Graphite Creek mine near Nome and $1.4 billion for a 100,000 t/y anode materials plant in Niles, Ohio, repayable over 15 years. EXIM signals willingness to fund roughly 70% of capex to first production, with Graphite One targeting initial 25,000 t/y anode output by mid-2027 and mine start-up in 2030 under a 20-year life. The project is post-feasibility, advancing under FAST-41 permitting, and already has $37.5 million US Department of Defense support.

    Erdene’s Bayan Khundii gold mine: capex, ramp-up and district upside for engineers

    Erdene Resource Development has poured first gold at its Bayan Khundii open-pit mine in southwest Mongolia and is ramping to nameplate output of 85,000 oz. per year from a 650,000 tpa plant, underpinned by 3.8 Mt of proven and probable reserves grading 3.8 g/t gold and 1.7 g/t silver for a six-year mine life. The 50-50 joint venture with Mongolian Mining Corporation has invested about $115 million, installed a 240 km power line from Inner Mongolia and employs roughly 500 people, signalling district-scale intent. Nearby Zuun Mod, 35 km east, holds 271 Mt measured and indicated at 0.06% Mo and 0.06% Cu plus similar-scale inferred resources, positioning it as a potential major molybdenum-copper supplier to China.
