A proposed open-pit gold mining project with underground workings (2019).
The Project site is located in approximately 120 km northeast of the city of Lagos, and 18 km south of the regional centre of Ilesha. It is situated between the town of Iperindo and village of Odo Ijesha.
The project property comprises a mining licence (ML41) covering an area of 1,720 ha.
The area is well known for its gold production from eluvial placers. Modern mining of the alluvial and eluvial deposits began in 1942 and official records state an annual historic production of approximately 23,000 oz gold.
The Segilola deposit, formerly known as the Iperindo Reef, was first discovered during the working of the eluvial deposits in 1945.
