Comments on the workings information

  • Old underground workings and more recent surface exploration

Comments on other economic factors

  • In 1991 the property contained a drill indicated resource of 100,000 ounces of gold.
    The mine produced a small amount in 1980-81.

    1996 the property was reported to contain a resource of 5,000,000 short tons of material grading 0.08 ounces of gold per ton.

Comments on development

  • Location uncertain and UTMs taken from approximate location of Isabella claims owned by above named companies. Norsemont Mining Corp. optioned property to Homestake about 1990.
    in 1999 a new mining syndicate formed by Franc-Or Resources Corp., Ranger Minerals Ltd., and Cordilleran Exploration Co. is evaluating a claim group in the Fitting district. The syndicate has staked five properties in Nevada so far and geologic mapping and sampling are reported to be underway (Northern Miner, 12/20/1999). In 2000,Cordilleran Nevada syndicate placed surface work on hold at the Fitting property (77 unpatented claims) until a complicated land ownership situation is resolved on adjoining ground. The property hosts a Carlin-type system, with shales and shaly limestones that locally display broad zones of decalcification, sanded dolomite, and brecciated jasperoid that may run up to 0.06 opt Au (Franc-Or Resources
    Corp., 8/31/2000)
