Deposit MANTO 0 NOT WORKED AND POORLY EXPOSED. MANTO 1 140 BY 150 M, 1.6 M THICK MINED TO 120 M DEPTH. MANTO 2 IS 75 M LONG WORKED TO 60 M DEPTH. MANTOS 3 AND 4 NOT EXPOSED NOR WORKED. MINERALIZATION EXTENDS 1000 M ALONG STRIKE, DISSAPEARS UNDER BASALT TO NORTH, THINS OUT TO SOUTH. DEPOSIT CONSISTS OF A MINERALIZED COARSE GRAINED SANDSTONE TO CONGLOMERATE SANDWICHED BETWEEN TWO MINERALIZED AND ALTERED BASALT FLOWS. SEDIMENTS ARE A FLUVIAL FACIES WITHIN A LACUSTRINE SEQUENCE. MINERALIZATION IN CONGLOMERATE CONSISTS OF A SERICITE-KAOLINITE MATRIX WITH NODULES AND POCKETS OF CU MINERALS. IN SANDSTONES CU MINERALS FOLLOW STRATIFICATION. ALL SEDIMENTS ARE CUT BY MINERALIZED SUBVERTICAL FRACTURES FILLED BY CUPRITE-TENNANTITE-CELESTITE?, INCLUDING SHALE BEDS. BASALT IS INTENSELY ALTERED BY CHLORITE-KAOLINITE-CARBONATE AND HOSTS IMPREGNATIONS AND IRREGULAR VEINLETS OF CUPRITE. NATIVE CU REPLACED CALCITE CEMENT, CHRYSOCOLLA REPLACES MATRIX OF BASALT.
