Recovering gold. Restoring land. Creating value.
Minerra Ghana transforms historic mine tailings into valuable gold while reducing environmental impact through advanced mineral processing technologies.
Africa's leader in sustainable gold recovery from mine tailings.
Minerra Ghana transforms historic mine tailings into valuable gold — while reducing environmental liabilities across West Africa's mining belt.
Advanced mineral processing
Gravity concentration, flotation and carbon-in-leach circuits engineered for legacy tailings mineralogy — recovering the gold yesterday's plants left behind.
Environmental rehabilitation
Every project ends with cover systems, native-species revegetation and long-term monitoring — legacy environmental liabilities converted into rehabilitated ground.
Ghanaian owned, globally aligned
Fully Ghanaian-owned. Compliance framework aligned to the Minerals Commission, EPA Ghana, GISTM tailings guidelines and Tier-1 contractor pre-qualification standards.
We combine deep local knowledge — Ghana's varied geology, its regulatory framework, the community dynamics that shape every mine site — with the engineering precision that large-scale producers expect from their contractors.
Yesterday's mines left behind more than pits. Across Ghana's mining belt, historic tailings storage facilities hold billions of tonnes of processed rock — and with it, unrecovered gold, environmental liability, and a chance to do better.
Mine tailings, explained.
Tailings are the fine ground rock left after ore has been milled and metal extracted — typically stored as slurry behind engineered dams for decades.
An environmental liability.
Legacy TSFs risk seepage into groundwater, dust migration, and catastrophic dam failure. They occupy productive land that could be rehabilitated.
Gold left in the ground.
Historic recovery rates of 60–70% mean today's higher-efficiency circuits can extract meaningful grade — 0.6–1.2 g/t Au is common in Ghana's older TSFs.
Reprocessing heals the land.
Every tonne re-processed shrinks the dam, recycles the water, and hands back rehabilitated ground — commercial return and environmental return, together.
A resource opportunity already mined once.
Legacy tailings offer a rare combination for institutional capital: defined resource, near-surface access, lower ESG risk than greenfield, and a clear rehabilitation exit.
Estimated in-situ gold across Ghana's characterised legacy TSFs at current spot.
From feedstock previously milled to only 60–70% recovery — the modern uplift.
From resource statement through commissioning, on already-permitted TSF ground.
Zero greenfield footprint — a materially lower ESG-risk profile than new-pit projects.
