a ss — oe No: 3. SMatt VEIN~ON SULLIVAN CLAIM, “WITH TUNNEL STARTED UNDER FOOTWALL. and dips to the Southwest. Along the footwall values are obtained of 2.0 ozs. gold and 47 to 51 ozs. silver to the ton.. The mineraliza- tion here occurs in the form of marcasite and arsenical iron in a quartz gangue. A tunnel has been started under the footwall of a small parallel vein, between the two veins. (See Cut No. 3.) These veins occur in a mineralized zone lying between greenstone on the South and porphyry-on the North. At the top of the draw the Salmon River formation, an old sedimentary, overlies the ereenstone, while still higher up an argillite, known as the Nass formation, a later sedimentary, overhes the Salmon River forma- tion. On the Daly claim a galena vein, striking in a North-South direction, outcrops along the face of a porphyry bluff, and lies between diorite and porphyry. This vein is narrow on the surface but widens as it goes down.
