The Ogama and Rockland deposits are of similiar type, occuring in veins which occupy shear zones about 500m apart. The Ogama vein is for the most part less than 30cm wide, and the Rockland vein varies in thickness from 30cm to almost 1m.

The ore assemblage is pyrite and chalcopyrite, with minor sphalerite, galena and arsenopyrite, and the gangue is quartz with a little sercite. Free gold was observed on the dumps. Wall rock alteration reflects the granitic composition of the host and is largely quartz, sercite, carbonate and pyrite; chlorite is scarce.

The Ogama shaft reached a depth of 314m and the Rockland shaft 83m. During the initial phase of production, cut short by the Second World War, ore from the Ogama deposit was trucked to the Gunnar mill. In 1946, the Gunnar surface installation was moved to the Ogama-Rockland site.
