Report of the State Mineralogist . de strikes N. 10° W. and dips 65° has been traced 1300 feet on the surface. There were 3 levels at;70, 200 and 400 ft. when visited by the writer, July 27, 1920. The200 level had been driven north 275 feet, and south 175 feet, and the400 level north 245 feet and south 250 feet. The shaft passed intothe footwall between 200 and 400 levels. The 200 level north showsa stringer lead of quartz and calcite between a grey slaty schist hangingwall and meta-andesite footwall, with some bornite disseminated throughthe hard grey wall rock. From No. 1 crosscut on the 200 level south,which is not drifted on the vein, they had exposed the formation 16 and had raised 45 ft. on it. On the 400 level south, the driftwas not on the vein for 200 ft., but at that distance from the shaftthey cut a black slate gouge carrying quartz stringers and had driftedon it 50 feet. On the 400 level north, the footwall is hard, dark greenmeta-andesite and hanging wall is slaty black schist. There was no. Photo No. 58. Mill building and headframe at Gruss Mine, near Genesee. gouge north of shaft. The superintendent claimed the slate wasgold ore, with the gold presumably in the pyrite. Three men were working underground when visited. The mine givesconsiderable water, nearly all of it coming in along the is a 10 Cornish pump in the shaft and an 8 lift pump onthe 400 level. The shaft and mill are on the Genesee claim in theSE. i of NE. J of section 15, and so far as known no work was beingdone on the other claims. On the 400 level a crosscut had been driven245 ft. east in search of the Cooper vein, and it was though it wouldrequire 155 ft. more crosscut to reach it. No pay shoots had beenblocked out as far as known, when the property was visited, althoughGruss stated they had mined an ore shoot in years past which was150 ft. long 125 ft. above the 200 level north. Hoisting is done in a cage. Ore is crushed in a McCully crusherin the headframe
