Comments on development

  • Discovered by drilling. The original owner of this property was Cleve Van Dyke. Van Dyke copper owned many claims throughout Miami area, but produced only from the Van Dyke shaft. Drilling on this deposit began 1925 and it is one of the deepest deposits in the district. Kocide mining corp. suspended in-situ leaching operations at this site in 1990 due to iron build up in the recycled leach solution; they had been producing cement copper since 1988.
