|Current site name||Salmon River Bench|
|Geographic coordinates:||-161.70268, 58.93925 (WGS84)|
|Relative position||This record describes the Salmon River Bench mine, and the subsurface extension of the deposit as defined by drilling.. The Salmon River Bench mine is along the east side of Salmon River valley. Dredge mining has taken place from opposite the mouth of Dowry Creek at a surface elevation of about 275 feet, south 2 miles to opposite the mouth of Platinum Creek at a surface elevation about 175 feet. The area of dredge tailings is commonly 600 to 700 feet wide. The map site is at the approximate midpoint of the placer tailings. This mine is included in locality 12 of Cobb (1972 [MF 362]; 1980 [OF 80-909]). The subsurface extension of this deposit has been traced southward by drilling for a distance of about 10 miles, to within 3/4 mile of the coast of Kuskokwim Bay.|
