Comments on the geologic information

  • Geologic Description = The Denali Bench gravels, as defined by Smith (1971), are on the south side of Valdez Creek upstream from the Dry Creek Cut (HE195). The gravels occur both on the bedrock bench and in a paleochannel. The paleochannel contains large, rounded boulders; it grades upwards into well-bedded fluvial gravels. All lithologies in the gravels appear to have been derived from within the Valdez Creek valley.
  • Age = Quaternary.

Economic information about the deposit and operations

Comments on the reserve resource information

  • Reserves = There is a large resource of sub-economic gold-bearing gravels.

Comments on the workings information

  • Workings / Exploration = Small-scale mechanical and hydraulic operations have tested the tenor of the exposed gravels. Some drilling has been completed on portions of the bench gravels.
