Location: This tunnel is at an elevation of approximately 800 feet on the north side of Sheep Creek at Portal Camp. It is 1 mile south of Sheep Mountain, just about the center of the south side of section 28, T. 41 S., R. 68 E. of the Copper River Meridian. The location is accurate. This tunnel is part of the Alaska-Juneau Mine (JU165) and included as a separate site because it is marked by a symbol on the Juneau B-1 topographic map.
Geology: This tunnel is a crosscut driven in 1912 to access the Perseverance and Alaska-Juneau orebodies. It was a haulage and access tunnel and is part of the Alaska Juneau mine (JU165) and the Perseverance mine (JU168). During 1986-1988 Echo Bay Mines renovated the Sheep Creek Tunnel, completed a 2,000 foot decline to the AJ 4 level, and drove 1,100 feet of new workings in the Perseverance mine (Redman and others, 1989). The Sheep Creek Tunnel passes through numerous quartz veins and quartz vein stockworks that are part of the Alaska-Juneau mine.
