A Cu occurrence/prospect with surface workings located in sec. 19, T13S, R12E.

Mineralization is a contact metasomatic deposit with ore in veinlets hosted in quartz monzonite. Alteration is propylitic.

Veinlets of epidote plus quartz plus blobs of chalcopyrite, mostly oxidied to tenorite(?) plus limonite plus malachite to 1 cm. Also, additional malachite is disseminated throughout veinlets and on fractures. Veins are very irregular, with a selvage of quartz plus chlorite(?). Also there are some magnetite-specular hematite veinlets which contain some malachite.

Workings include a pit.
