Iron Project
The Dogoro Iron Ore Permit in the Siby Commune, Mali, covers 765 km² and hosts significant high-grade hematite and maghemite mineralization associated with BIF formations. The area contains both in-situ and floating ore across multiple zones, with proven reserves of 272 million tonnes. The project supports production levels between 2–5 million tonnes per year and has strong logistical access via major West African ports. The geology, ore grade, and deposit continuity indicate substantial commercial mining potential

Proven Reserves: 272 million tonnes of iron ore
Mining Method: Open-pit mining (outcrop & near-surface ore)
Key mineralization points:
- Iron occurs mainly as hematite, magnetite-derived maghemite, and BIF (banded iron formation).
High magnetic anomalies on the map indicate magnetite-rich BIF units.
Hematite and maghemite appear due to oxidation and weathering of magnetite.
Mineralization occurs mostly in plateau edges, subcropping up to ~50 m depth.
Secondary ore appears in sub-plateaus with scattered fragments.
GH Mining focuses on long-term, responsible growth to deliver superior shareholder returns. We develop high-quality ore bodies into efficient, long-life operations in West Africa. Our mining and processing of minerals meet vital consumer needs, improve living standards, and are conducted safely, responsibly, and sustainably.
