Porphyry and skarn Cu-Au deposits. The porphyry Cu-Au deposit is hosted in a north-south-trending belt of variably metamorphosed mid-paleozoic volcanic extrusive, sedimentary and intrusive rocks that include andesitic to dacitic lava flows, tuffs, ignimbrites and granitic to monzodioritic stocks and plutons. The Cu-Au skarn occurs at the approximate centre of a sub-volcanic complex, consisting of dacitic to andesitic pyroclastics and epiclastics. These units are intruded by a series of quartz diorite porphyry dykes and late-stage, post-mineral andesitic to basaltic andesite.

The skarn body was worked by an underground mine that was shut down in 2005. The porphyry deposit is only explored by a prospect, that is operated by Ivanhoe Mines Ltd.
