Economic information about the deposit and operations

Development status Prospect
Commodity type Metallic

Mining district

District name Breckenridge District

Comments on the reserve resource information

  • Drilled by FMC Gold Corp. in the mid-1980s. Numerous mineralized intercepts reported. Sunshine examined this property in 1988 as a submittal from FMC Gold Corp. Determined to have potential for several small orebodies. Two possibly economic orebodies were identified by FMC drilling, the "WP-9 Zone" and the "Elephant Zone". Estimated combined potential of 100,000 to 200,000 oz of gold. However, property not acquired by Sunshine due to high "political and environmental risks", being close to a resort area.
  • Overall average drill-defined widths in stockworks zone of 17.3 ft grading 0.28 oz/ton Au. Mineralization is interpreted to be "spotty" however.
