Deposit QUARTZ STOCKWORK IS ABUNDANT, SERICITIZATION IS LOCALLY PREVALENT, BUT K-SPAR-QUARTZ ALTERATION PREDOMINATES IN MO-ST ROCK. SHEETING IN RHYOLITE AVERAGES N20E, DIP 75 SW. LOCALL-Y SOME FLAT STRUCTURES WITH ABUNDANT SERICITE DIP AS LOW AS 15- DEGREES. MINERALIZED ZONES IN WEAVER RHYOLITE FOLLOW N20E, 75- SW DIP OF SHEETING. QUARTZ-SULFIDE STOCKWORKS ARE ABUNDANT AN-D PRESUMABLY CONTROL ORE DISTRIBUTION. BOTH OXIDE COPPER AND C-HALCOPYRITE OCCUR BUT ARE NOT ABUNDANT. MOST OF THE ORE (OVER -99%) IN THE PIT IS OXIDIZED. SULFIDE IS MORE ABUNDANT IN OLD P-IT ALONG CONTACT LODE. MINE FOREMAN STATES ORE AVERAGES 2 OZ/T- AG; LACANA GEOLOGIST STATES ORE AVERAGES 1 OZ/T AG, WITH TRAC-E OF AU. UNOXIDIZED ROCK CONTAINS ABUNDANT DISSEMINATED PYRITE-, MINOR CHALCOPYRITE AND SOME SULFIDES IN QUARTZ VEINLETS AND -AS SULFIDE STOCKWORKS.; MODEL NAME COULD ALSO BE: COMSTOCK EPITHERMAL VEIN.
