Comments

Comment (Location): ON TRIBUTARY OF WEST FORK PACKER CREEK

Comment (Development): MINE WAS DEVELOPING IN 1971 .

Comment (Deposit): CHIEF VEIN IS SIDERITIC. SOME OF THE RICHEST ORE WAS OBTAINED FROM A BRANCH OF THIS VEIN.

Comment (Workings): WORKINGS CONSIST OF THREE ADITS WITH A VERTICAL RANGE OF ABOUT 500 FT.

Comment (Geology): BEDS DIP STEEPLY AND ARE CONSIDERABLY FOLDED. IN PLACES THEY ARE TRAVERSED BY BROAD ZONES OF "CRUMPLING AND MASHING" AS WELL AS BY MORE SHAPLY DEFINED FISSURES, MOST OF WHICH STRIKE NW.
