Location: Martin Creek is a tributary of the Resurrection River; it is located in T. 2 N., R. 2 W., of the Seward Meridian. The placer occurrence is in sections 13, 14, and 23. The map location (in the SE1/4 section 14) represents the center of the occurrence, which is about 2.5 miles long. This is location P-53 of Jansons and others (1984). This location is accurate to within 300 feet.
Geology: Bedrock in the area is slate and graywacke of the Valdez Group of Late Cretaceous age (Nelson and others, 1985). Martin Creek flows in a narrow steep-walled canyon. The creek has a high gradient with many waterfalls and rapids. Evidence of early prospecting is seen in the lower part of the creek but there are no signs of large-scale operations. The lower section has low mineral development potential; the middle section has moderate potential (Jansons and others, 1984). The lower section is not considered to be an occurrence. Five suction dredge samples contained 0.0008 and 0.0278 ounce of gold per hour (Hoekzema and Sherman, 1983). Three 0.1-cubic-yard sluice samples contained from a trace to 0.0106 ounce of gold per cubic yard. Pan samples of bedrock gravels yielded 0.1537 ounce of gold per cubic yard. Coarse gold was recovered in gravels resting on bedrock fractures located just below the Mount Ascension tributary.
Workings: Although evidence of prospecting was reported, details were not provided (Jansons and others, 1984). The U.S. Bureau of Mines sampled the lower and middle sections of the creek. Five suction dredge samples contained 0.0008 and 0.0278 ounce of gold per hour (Hoekzema and Sherman, 1983). Three 0.1-cubic-yard sluice samples contained from a trace to 0.0106 ounce of gold per cubic yard. Pan samples of bedrock gravels yielded 0.1537 ounce of gold per cubic yard. Coarse gold was recovered in gravels resting on bedrock fractures located just below the Mount Ascension tributary.
