Overview#
Osun's resource base is gold + granite + cocoa + textile-dyeing pigment (the Osogbo indigo tradition). The state's gold belt — Iperindo, Ilesa, Igun-Ijesha — is one of the longest continuously-worked gold provinces in West Africa (continuous artisanal extraction since c. 1900); it underpinned Wesley De Souza Segun Mining (defunct) and a brief 1970s MNCs gold programme. Cocoa, kola and tobacco round out the agricultural footprint.
Geology & Deposits#
Gold. Ilesa-Iperindo-Igun-Ijesa basement complex belt — the most economically attractive primary gold belt in southern Nigeria; vein-and-placer. Granite & dimension stone. Ife, Osogbo, Ilesa. Tantalite, columbite, beryl. Iperindo pegmatites. Limestone, kaolin, clay. Erin-Ijesha border, Ipetu-Ijesa. Cocoa, kola, tobacco. Ife-Ijesa axis. Mineral water. Ipetu-Ijesa, Erin-Ijesha — bottled springs. Hydrocarbons. None.
Operators & Output#
- Segilola Resources Operating Ltd (Thor Explorations) — Segilola Gold Project, Iperindo: the country's first industrial-scale gold mine of the modern era, commissioned June 2021. Production ~80,000–90,000 oz Au/year. Initial mine life 5–7 years from open pit; underground extension under feasibility. - Multiple artisanal miners — Igun-Ijesa, Iperindo periphery. - Smallholder cocoa + kola.
Host-Community & Revenue#
No oil derivation. Segilola pays royalties and Nigerian Government Production Sharing into the Federation Account. The Iperindo–Igun-Ijesa community-development agreements under the 2007 Minerals Act are among the most-watched in the country.
Current Status#
Producing: Segilola Gold (industrial), granite, artisanal gold (Igun-Ijesa), cocoa, kola, bottled water. Frontier: deeper Iperindo underground; the wider Ilesa belt remains under-explored at industrial scale.
