What Eagle Mine does

Eagle Mine is a privately held underground mining operation located in western Marquette County, Michigan's Upper Peninsula, that produces high-grade nickel and copper concentrates and supplies approximately 1.5% of global nickel output. The integrated operation consists of the Eagle Mine (underground extraction at the Big Bay site) and the Humboldt Mill (a flotation processing facility 66 miles away in Champion), both operating under a single corporate entity. Ore is crushed, ground, and processed via flotation to produce concentrates that are shipped by rail car to downstream battery manufacturers and industrial metal processors under negotiated B2B contracts.

The operation's core technology stack centers on underground high-grade ore extraction paired with flotation-based concentration at the Humboldt Mill, supplemented by proprietary pyrrhotite flotation technology developed with Michigan Tech University and Revex Technologies, and a partnership with Allonnia for biological/enzymatic nickel purification. Closed-loop water systems recycle over 96% of process water, and over 85% of disturbed land is targeted for restoration. The REV Nickel Project, selected for up to $145 million in U.S. Department of Energy funding, is extending the operation's product surface into nickel recovery from mine tailings and spent lithium-ion batteries.

Commercially, Eagle Mine generates revenue through one-time bulk sales of nickel and copper concentrates to enterprise customers in the EV/battery supply chain and industrial metals processing segments. The company does not publicly disclose pricing or contract terms. Eagle Mine was owned and operated by Lundin Mining from inception through December 2025; the sale to Talon Metals (OTCMKTS:TLOFF) completed on January 9, 2026, repositioning the asset as the operational core of a U.S.-centric critical minerals platform. The operation employs 470 employees and contractors and has contributed an estimated $4.3 billion to the local economy since 2014.

Revenue model

1. Nickel and Copper Concentrate Sales: Eagle Mine extracts high-grade nickel and copper ore from its underground operation in Michigan's Upper Peninsula. The ore is processed at the Humboldt Mill through crushing, grinding, and flotation, then shipped via rail car to customers. The mine produces approximately 1.5% of the world's nickel supply.

Core offering

Eagle Mine is an underground, high-grade nickel and copper mine located in Michigan's Upper Peninsula that produces mineral concentrates at the Humboldt Mill. Ore is extracted underground, transported 66 miles to the mill, and processed via crushing, grinding, and flotation into nickel and copper concentrates that are sold in bulk via rail to battery manufacturers, steel producers, and industrial metal processors. The operation also runs a community battery recycling program that collects and ships batteries to downstream processors.

Product overview

Eagle Mine operates as a single-site mining operation consisting of two integrated facilities: the Eagle Mine (an underground high-grade nickel and copper mine) and the Humboldt Mill (a processing facility that crushes, grinds, and processes ore through flotation). The operation also offers battery recycling services through partnerships. The mine and mill work together as a unified production system, with ore transported 66 miles from mine to mill for processing.

Products and services

• Eagle Mine (underground nickel and copper mine) Underground, high-grade nickel and copper mine located in western Marquette County of Michigan's Upper Peninsula. Produces approximately 1.5% of the world's nickel supply for sale to industrial processors and battery manufacturers.
• Humboldt Mill (ore processing facility) Processing mill that extracts nickel and copper at lower grades through crushing, grinding, and flotation, enabling better use of the mineral resource, longer mine life, and increased tax contribution. Located 66 miles from the Eagle Mine site in Champion, Michigan.
• Battery Recycling Program Community battery recycling collection and processing service where batteries are sorted, packaged, and shipped to Creative Metals Group in Chicago for downstream processing, in partnership with OSI and Recycle 906.

Partnerships

Six partnerships are on record, tiered core and supporting.

• Talon MetalscoreStrategic or Co-development Partner · 9 January 2026Talon Metals completed the acquisition of Eagle Mine and Humboldt Mill from Lundin Mining on January 9, 2026. The acquisition transforms Talon from a speculative nickel developer into an operational entity with cash flow. Talon has been conducting exploration at the Boulderdash site 8 miles from Eagle Mine and has invested in extending the mine's operational life.
• Revex TechnologiescoreStrategic or Co-development Partner · 20 September 2024Revex Technologies, a startup company formed in 2023 through partnership between Michigan Tech University and Eagle Mine (then Lundin Mining), was awarded $145 million from the U.S. Department of Energy for the REV Nickel Project. Eagle Mine plays a pivotal role in this initiative aimed at producing nickel concentrate from waste streams including mine tailings and spent lithium-ion batteries.
• Upper Peninsula Construction Council (UPCC)supportingChannel Partner/ Reseller/ Distributor · 20 September 2024UPCC is working with Eagle Mine and Revex Technologies to ensure local labor is used during construction of the REV Nickel Project facilities.
• Michigan Building & Construction Trades Council (MBCTC)supportingChannel Partner/ Reseller/ Distributor · 20 September 2024MBCTC is working with Eagle Mine and Revex Technologies to ensure local labor is used during construction of the REV Nickel Project facilities.
• Michigan Technological UniversitycoreStrategic or Co-development Partner · 1 January 2023Michigan Tech University partnered with Eagle Mine on multiple years of research that led to the creation of Revex Technologies. The partnership developed technology for extracting nickel and other critical minerals from mine waste streams and spent batteries.
• VoconiqsupportingGTM or Marketing Partner · 1 January 2023Eagle Mine partners with Voconiq for its Local Voices community engagement survey program.

Broad incumbents

• Vale S.A. Brazilian diversified mining giant and one of the world's largest nickel producers (via Sudbury and Indonesian operations) as well as a major copper producer. Comparable to Eagle as a primary nickel/copper miner, though at vastly larger scale and broader geographic footprint.
• Glencore: Global mining and commodities trading giant with major copper, nickel, and zinc divisions. Comparable to Eagle on commodity exposure and B2B concentrate offtake, though Glencore operates at multiples of Eagle's scale across many geographies.
• Norilsk Nickel (Nornickel): World's largest palladium and high-grade nickel producer, with substantial copper output. Comparable as a major primary nickel/copper producer though vastly larger scale and Russian-domiciled.
• BHP Group: Largest diversified mining company globally, with significant nickel (Western Australia), copper, and critical minerals exposure. Comparable as a major producer aligned with EV/battery supply chains, though at vastly larger scale.
• Anglo American: Global diversified miner with major copper, nickel (Codemin via Codemin/Japurá), and platinum group metals exposure. Comparable on commodity exposure and B2B offtake model, though with global multi-asset diversification.

Direct peers

• Lundin Mining: Former owner and operator of Eagle Mine (until January 2026); Lundin Mining is a diversified mid-tier base metals producer with significant copper, nickel, and zinc operations including the Eagle Mine asset it just divested. It is the most directly comparable peer on portfolio, geography, and business model.
• Talon Metals: Current parent company of Eagle Mine (acquired January 2026); Talon is a U.S.-focused nickel development company whose flagship Tamarack project targets battery-grade nickel. Eagle gives Talon operational cash flow that complements its exploration portfolio.
• MP Materials: U.S.-based critical minerals producer and operator of the Mountain Pass rare earth mine, with parallel positioning as a domestic supplier of strategic materials for clean energy and defense applications — directly comparable to Eagle Mine as a U.S. strategic critical minerals platform.
• First Quantum Minerals: Mid-tier base metals producer focused primarily on copper with nickel byproducts; comparable to Eagle in terms of concentrate production, mine operations, and exposure to base metals demand from battery and infrastructure markets.
• Hudbay Minerals: Mid-tier copper producer with zinc and byproduct nickel exposure operating in the Americas (Canada, Peru, U.S.). Like Eagle, Hudbay is a single-region base metals operator with nickel/copper concentrate output.
