Subject category Comment text
Deposit OCHEROUS GOSSAN AND SPOTTY VEIN QUARTZ OCCUR ALONG ONE OR MORE N 30-40 W, HIGH-ANGLE FAULTS IN LIGHT GRAY CHERT. RARE PYRITE REMNANTS WERE NOTED. THE ZONE OF FAULTS IS LESS THAN 25 M WIDE; MINERALIZED FAULTS ARE DEFINED BY PITS AND ADITS. SOME CRUSTIFORM QUARTZ-GOSSAN (ORIGINALLY SULFIDE) BANDING WAS NOTED IN ONE PIT. MARSH AND ERICKSON SHOW A NW-TRENDING FAULT HERE. A DIKE OF QUARTZ MONZONITE IS SHOWN NEARBY TO THE WEST. SIMILAR OXIDE COPPER AND GOSSAN PROSPECTS ARE EXPOSED IN TRENCHES IN S/2 SEC 29, T 34 N, R 42 E DIRECTLY ADJACENT TO THE INTRUSIVE MASS OF QUARTZ MONZONITE. CONSIDERING THE MINOR NATURE OF THE PROSPECTS, THERE HAS BEEN A CONSIDERABLE AMOUNT OF BULLDOZER TRENCHING IN AN AREA, OF 6-7 KM 2. BULLDOZER ROADS IN E2, SEC 30, T 34 N, R 42 E, ARE NOT SHOWN ON THE REVISED (1981) TOPO SHEET, AND ARE CERTAINLY LESS THAN 5 YEARS OLD. THE ROADS ARE FOR DRILL PADS FOR ROTARY DRILL HOLES, PRESUMABLY FOR PRECIOUS METALS. THIS ACTIVITY MAY BE RELATED TO CLAIM STAKING OF THE
Deposit BUFFALO CLAIMS WITH PVC PIPE.
