Deposit MINERALIZED STOCKWORK FRACTURES, WITH DENSITES OF 5 TO 20 PER M, IN SILICIFIED CALCAREOUS QUARTZOSE SANDSTONE. THE NE TRENDING FRACTURES ARE WIDER THAN THE NW TRENDING FRACTURES. VEINS ARE 0.5 TO 3.0 CM WIDE WITH SMALL POCKETS 0.2 TO 0.5 M WIDE AT VEIN INTERSECTIONS. UP TO 10 VOL. PERCENT PYRITE- TETRAHEDRITE DISSEMINATED IN WALL ROCK. LESS INTENSE VEINING AND DISSEMINATED MINERALIZATION IN OVERLYING LIMESTONE. SCARCE VEINLETS IN CAPPING SHALES. OVERALL, MANTO ORE BODY IS 30 M THICK.
