Economic information

Geologic structures

Type of structure Local
Structure description ore shoots localized at vein intersections and by changes in strike or dip of vein

Comments on the geologic information

  • Ore has been found in sulfide veins filling fissures, over a vertical range of 1,600 feet; major veins include the Lamartine, Crown, Oneida, Mendick, and Great Western.

Economic information about the deposit and operations

Development status Past Producer
Commodity type Metallic
Significant No

Mining district

District name Freeland-Lamartine District

Comments on the production information

  • GOLD PROD. 78,184.71 OZ; 3,092 962 OZ. AG; 162,802 POUNDS CU; 5,601,598 POUNDS PB; 1,258,136 POUNDS ZN FROM 300,000 TONS OF ORE (FROM 1867 TO 1952).

Comments on the reserve resource information

  • An undated report estimated 734,120 tons of ore remaining in adits and estimated 3,000,000 more under the old workings. An analysis dated 1965 cautioned that available resources may be considerably less and grades were not predictable on the basis of available data. More recent calculations indicate that 50,000 to 200,000 tons of dump and tailings material may also be a resource. (Sunshine files)

Comments on the workings information

  • The Lamartine has 12 miles of workings, the most extensive in the district, over a vertical range of 1,800 feet.
