Highest revenue per tonne
Liberates by-product metals that conventional processes leave stranded in the residue.
A new pathway for critical minerals.
Eos Metals is commercialising a breakthrough bacterial-leach ore refining technology beginning with a first joint venture alongside an established nickel producer in New Caledonia, home to some of the world's premier nickel-laterite resources.
The technologyAmbient
temperature and pressure operation — no heat, no high-pressure vessels.
Acid-free
bacterial leach using common soil organisms; tailings are minimal and benign.
Low Power
processing alleviates a significant bottleneck to further HPAL and RKEF expansion.
Multi-metal
nickel, cobalt and manganese — with optional recovery of scandium and rare earths.
The technology
Breakthrough bacterial-leach refining.
Eos holds the rights to commercialise a breakthrough bacterial-leach refining process developed by Brokkr.
About the Brokkr processFully modular
Scales in phases with a much smaller footprint than HPAL or RKEF plants.
Ambient conditions
Operates at ordinary temperature and pressure — no heat load, no pressure vessels.
Acid-free & BSL-1 safe
Uses common, soil-native bacteria at the lowest bio-safety classification — no acid circuit.
Low capex & opex
Capital and operating cost per tonne materially below conventional RKEF and HPAL routes.
Low energy, low CO₂
A small energy requirement and a correspondingly low carbon intensity.
Minimal, benign tailings
No acid effluent and no hazardous impoundment; residues are benign, with downstream reuse potential.
Multi-metal recovery
Nickel, cobalt and manganese, with optional recovery of scandium and rare earths.
Applications
One technology, many ore bodies.
The process is effective across a broad range of terrestrial ores, giving mine owners and critical-mineral customers a new route to value from resources that conventional processing cannot economically treat.
Laterite nickel
The primary application — nickel, cobalt and manganese from lateritic ores, including limonite that existing miners bypass.
Manganese
Recovered as a co-product and treatable as a primary feed in its own right.
Scandium & rare earths
High-value elements recoverable alongside the primary metals, adding to revenue per tonne.
Eos is a land-based business. Beyond terrestrial ores, the Brokkr process is also a responsible, effective option for processing polymetallic nodules — a route we are pleased to discuss with interested parties.
The first project
New Caledonia — the optimal place to start.
Eos evaluated dozens of joint-venture opportunities with partners across laterite ore basins around the world, and selected New Caledonia as the optimal place to begin: a French territory with a Western regulatory framework and more than 140 years of nickel history.
A world-class endowment
New Caledonia holds roughly a quarter of the world's lateritic nickel resources, yet produces only a small fraction of global supply — a rare combination of scale and headroom.
A stranded feedstock
Limonite — the upper laterite horizon — has limited use for existing miners, who process the deeper saprolite. Tens of millions of tonnes sit stockpiled, awaiting an economic route to market.
A secured position
Eos has established its first joint venture with an established local nickel producer, holding exclusive technology rights and a memorandum of understanding with a New Caledonian provincial entity.
Strategic diversification
A new, independent source of critical-mineral supply for offtakers managing geopolitical concentration risk.
Expansion potential
A modular first plant provides the template for staged growth across additional resources — the objective being a full-scale commercial plant as Phase 1.
Responsible by design
Reprocessing already-mined material, acid-free and with benign tailings.
Our approach
Prove. Build. Expand.
A disciplined path from proven technology to a producing operation and beyond — de-risking each step and building on modularity to grow.
01 · Prove
Validate the process.
Confirm performance and product quality at pilot scale, generating the operating data that underpins commercial design.
02 · Build
First commercial plant.
Engineer, finance and construct a full-scale commercial plant as Phase 1 on the New Caledonia feed.
03 · Expand
Grow in modules.
Replicate the modular design across further resources and jurisdictions, with partners seeking to unlock their own ore bodies.
Leadership & partners
Deep mining, metallurgical and capital-markets experience.
Eos brings together operators who have built and run mines, the scientists behind the technology, and partners with the finance and development track record to deliver it.
