|Current site name||Boulder Creek|
|Geographic coordinates:||-144.01263, 62.77968 (WGS84)|
|Relative position||This placer (Cobb, 1979 [OF 79-1247 p. 6] is near the head of Boulder Creek (which is not named on the Gulkana D-1 quadrangle) at an elevation of about 3,800 feet. The prospect is about 1000 feet south of the center of section 36, T. 12 N., R. 7 E., Copper River Meridian. The prospect is shown as a placer on figure 5 of Richter (1966). It is shown as location 22 of Richter and Matson (1972) and locality 21 of MacKevett and Holloway (1977).|

|Deposit||Model Name = Placer Au (Cox and Singer, 1986; model 39a)|
|Deposit||Other Comments = The association of stream sediment samples with anomalous gold and molybdenum near the elongate diorite pluton suggests that the intrusive and its contacts should be prospected for lode occurrences of gold and other metals.|
