Report: The Silver Dyke mine is located about three and a half miles up Carpenter Creek from its junction with Belt Creek (Robertson, 1951). The mine is a lead, silver, and zinc mine, and there are not any mill tailings on the site. The waste dumps were unvegetated and one adit had a significant flow. The water had a pH of 5.12, and the water exceeded drinking water standards for cadmium, copper, nickel, and antimony. The discharging water flowed over the waste rock and into Squaw Creek, and there were exceedances of drinking water standards for cadmium, copper, nickel, and antimony. The one hazardous opening is the glory hole on the hilltop (above the adit) has very steep sides and the fence (erected by the DSl) was down in places. The Silver Dyke mine is dry and the waste is going down hill. The ore body had a lenght of about 600 feet and a width of about 400 feet (Schafer, 1935). Schafer states that there were two adits located at different elevations. The lower adit was about 1000 feet long and a 36 gage track was installed. There is also an open pit.
