Strike Pay Grade Ore


 When the present operators took over the property work was imme- diately resumed in the old 4th level and a crosscut drift driven around tie caved portion of the Bonanza" stope to the footwall for the purpose of drawing the large tonnage Of vari- grade ore. By utilizing supplement tary milling appliances-soo to be installed-the greater portion of this tonnage can be reduced at q profit In driving across the strike of the old ore bodies to reach the footwall of the "cave" 37 feet of ore was encountered. Fifteen feet of 1t assayed SIT gold per ton. The remaining 22 feet, while low grade, has commercial value. The ore stopped from this deposit milled $9.SS gold per ton.
 The same ore body has been opened on the 9th level, (5O feet below) by q crosscut s5 feet long. Two veins-one pitching to the east and the other to the west-were tapped at that point Subsequent development demonstrated that the ore body on the 4th level was formed by the juncture of these veins Just below the floor of the level. The west vein gives assay returns of from S6 to $22 per ton. The ore taken out milled trifle better than $8 gold per ton. This vein proves to be the down ward extension of the old "Bonanza' vein of which the "Casrle Garden" and Bonanza" ore shoots were a part Connection has been made with the deposit opened on the 4th level by an upraise and winze in ore.
 Strike Copper Sulphides An air-hoist was set up on the level and winze sunk 80 feet In ore to the 7th level. There drifts were run on the vein, north, 40 feet. and south. 80 feet. The pitch of this ore body is to the south. It was in the south drift on this level that copper sulphides first made their appearance in the mine. Check assays demon | state the ore carries about 5 per cent l copper and $35 gold per ton. As the l copper sulphide section lies against | the footwall of the vein, and pitches I rather flat to the southwest, the winze was sunk an additional 80 feet and the Sth level established.
 On the Sth level drifts were run north and south in the oxidized Of G. | One hundred feet from the station cop l per sulphides were again encountered q in the south drift. The crosscut at that point shows an ore breadth of l6 feet with the copper sulphide section along | the footwall carrying ore of the same grade as that (. .,ened above. The oxi- | ulZeu oIt oii lllt otfl leVel SdHlples | s13.90 gold per ton and for a length of 50 feet carries gold values as high as s3S per ton. Later the drift on the 7th level was continued in the oxidized ! portion of the vein, and 90 feet from | the station entered the same ore body | that is opened on the Sth level. The | crosscut there shows 10 feet or ore which gave SIP gold at the millheads At that point winze was sunk in ore about 40 feet, an upraise was made from the Sth level to connect there with, an dan intermediate level es- abolished. The ore in the latter has g width of 12 feet. That this ore body will prove of considerable size is ap- parent as it has been opened length of 45 feet and a width of 10 feet or the 7th level. a width of 12 feet at tho intermediate level, and width of 1t feet on the 8th level.
