Exploration of the area surrounding the historic Comstock copper mine entailed doing 1:5000 scale geological mapping, soil and rock chip geochemical sampling, the conduct of 7 line km of ground magnetic surveying and 4.8 line km of dipole-dipole IP surveying, and limited diamond drilling (2 inclined NQ/BQ cored holes for a total penetration of 505 m) to test beneath outcropping copper and zinc - rich gossans. No primary sulphide-bearing zone was encountered. Goethite and manganese oxides are common within the supergene interval drilled, and it is suspected that these minerals have scavenged and authigenically enriched the copper and zinc evident in surface gossans.
