Comments
Comment (Deposit): FRACTURE COATINGS AND DISSEMINATED IN PEGMATITE AND SCHIST, MALACHITE IS MOST ABUNDANT ALONG PEGMATITE-SCHIST CONTACTS AND IN MORE COARSELY-GRAINED SCHIST.
Comment (Workings): SEVERAL PROSPECT PITS AND AN ADIT DRIVEN NEAR A GRANITE-SCHIST CONTACT ABOUT 300 FT NORTH OF THE MAIN MINERALIZED ZONE. ADIT TRENDS N 6 E, PARALLEL TO CONTACT AND STRIKE OF MICA SCHIST.
