Economic information about the deposit and operations

Development status Occurrence
Commodity type Metallic
Deposit size Small
Significant No
Discovery year 1956
Discoverer A. F. Koelbl

Comments on the reserve resource information

  • THE GRADE AND TONNAGE IN THESE VEINS ARE PROBABLY NOT SUFFICIENT TO REPRESENT A MINABLE COPPER DEPOSIT, BUT GOLD AND SILVER VALUES ARE HIGH, AND COPPER IS A POTENTIAL BYPRODUCT OF THE PRECIOUS METALS (PEASE, 1966, P. 110).
