According to Len Kolff, chief geologist at IronRidge Resources, West Africa provides a significant opportunity for the discovery of world-class lithium deposits.
Breaking on the final day of the Paydirt Africa Down Under (ADU) mining conference in Perth, Australia recently, Kolff said West Africa is a globally significant lithium frontier, with proven high-grade lithium spodumene pegmatites.
Although West Africa is known for its gold deposits, there is growing excitement about the region’s lithium potential. IronRidge currently holds a 1 822km² portfolio of lithium exploration acreage in Ghana and the Ivory Coast.
IronRidge’s Cape Coast lithium project in Ghana is a 645km² land package secured via earn-in and application. The project is located on the coast within 100km of the operating Takoradi port and 100km from the capital of Accra via a bitumen highway.
The area contains a historical spodumene deposit of 1.48 million tonnes (Mt) at 1.66% lithium oxide (Li2O0 non JORC) and the company’s promising Ewoyaa discovery. IronRidge has just completed more than 8 000m of drilling at Ewoyaa in a programme which has already returned several promising high-grade lithium results.
“The initial drilling results represent a significant milestone for the Cape Coast lithium portfolio, with broad, continuous and high-grade lithium pegmatite intersections returned,” Mr Kolff said.
“Long drill intersections of 128m at 1.21% and 111m at 1.35% Li2O as well as very high-grade intersections up to 3m at 3.29% Li2O are a fantastic result for a first phase drill programme. They have helped confirm Ewoyaa as a significant discovery and provide confidence for further exploration success within the portfolio,” Kolff added.
