General comments

Subject category Comment text
Deposit ACCORDING TO ROHLFING, VEIN TRENDS N 80 W, 35 TO 40 SW AND VARIES FROM 1 TO 6 FT WIDE, AVERAGING 2.5 FT. HANGING WALL AND FOOTWALL ARE SMOOTH AND WELL MARKED, SIMILAR TO INDEPENDENCE VEIN. CRUSON'S MAP SHOWS LINEAMENTS NORTH OF MINE TRENDING APPROX N 55 E, WHICH CLOSER APPROXIMATES TREND OF NW CAULDRON MARGIN. HOWEVER, SMALL BRANCH FAULT INSIDE CAULDRON RIM JUST SOUTH OF MINE TRENDS N 80 TO 85 W.
