Comments on the geologic information

  • Geologic Description = The country rocks in the area of the Ready Cash prospect consist of several hundred meters of Upper Triassic interbedded limestone, marble, basalt, metachert, and argillite. The strata are intruded by quartz diorite porphyry dikes of probable Late Cretaceous to Early Tertiary age, and by Tertiary tourmaline-bearing granite. The Ready Cash prospect consists of quartz-calcite-sulfide veins, and pods of skarn. The ore minerals consist chiefly of arsenopyrite, pyrite, chalcopyrite, galena and sphalerite, accompanied by minor amounts of tetrahedrite, tennantite, argentite, and cassiterite. The skarn consists of pyrite, pyrrhotite and chalcopyrite in a matrix of calc-silicate minerals and sparse quartz. The deposit can be subdivided into: a) copper-rich pods of skarn having grades of 0.5 to 0.9% copper (Hawley and Clark, 1974); b) arsenopyrite-quartz veins, containing 0.08 ounce of gold per ton, 1.06 ounce of silver per ton, and 0.33% copper; and c) high silver-lead-tin veins containing up to 20.8 ounces of silver per ton, 4.0% lead, and 0.5% tin (Hawley and others, 1978). The several types of deposits may be related to two or more magmatic events in the area.? the deposit at the Ready Cash prospect is more or less continuous with the deposit at the Canyon Creek prospect (HE055), encompassing an area about 2.5 miles long and 1 mile wide.
  • Age = Probably Late Cretaceous and (or) younger.

Economic information about the deposit and operations

Development status Prospect
Commodity type Metallic

Comments on exploration

  • Status = Active

Mining district

District name Valdez Creek

Comments on the reserve resource information

  • Reserves = the two principal silver-rich veins on the prospect contain approximately 200,000 tons of ore carrying 10 to 20 ounces of silver per ton and 0.5% tin (C. Hawley, personal communication, 1999). This estimate does not include the skarn deposits.

Comments on the workings information

  • Workings / Exploration = Both surface and underground workings. Two tunnels, 170 feet and 75 long feet have been driven and there are several prospect pits.? the deposit can be subdivided into: a) copper-rich pods of skarn having grades of 0.5 to 0.9% copper (Hawley and Clark, 1974); b) arsenopyrite-quartz veins, containing 0.08 ounce of gold per ton, 1.06 ounce of silver per ton, and 0.33% copper; and c) high silver-lead-tin veins containing up to 20.8 ounces of silver per ton, 4.0% lead, and 0.5% tin (Hawley and others, 1978).
