Mineralization is hosted in a package of altered Kofi series quartz wacke, dolostone, and argillite interbedded with siltstones and sandstones. The sequence is intruded by 1- to 10-m-thick, variably albitized diorite and monzodiorite dikes, and cut by steeply dipping NNW-striking (80E/350) shear zones.
