Work History
Staked as Sarah, etc. cl (12587) in Jul/16 by W. Walker, who completed an 5.5 m adit in 1917 and hand trenching in 1918. The adjoining Alice, etc. cl (12689) were tied on by M.S. McCowan in Aug/18.
Restaked as Stibnite, etc. cl (15073) in Jul/26 by J.E. Hollenbeck, who hand trenched and built a trail in 1929; as Risky, etc. cl (57677) in Jul/51 by C.C.Henderson and adjoining Mystery, etc. cl (57701) in Aug/51 by A. Sansoucy, who hand trenched in 1952; and as Summit cl (78962) in Jul/60 by Yukon Cons Gold Corp, which trenched in 1961.
Restaked as Walker cl 1-6 (79291) in Aug/63 by F. Burkhard & C.C. Henderson. The showing was mapped and sampled under option in 1965-66 by Conwest, which added the Ant cl (87297) to the south in Nov/65.
J.A. Hanna optioned the Walker group and adjoining Sandow cl (86982) and Pika, etc. cl (Y56906) to the north in 1970 and performed mapping and trenching in 1971. The adjoining Syndy cl (87375) were staked in Apr/66 by W. Kaufman & B. Fitch and optioned by Mid-West ML which conducted sampling and trenching later in the year.
In Apr/79 Anaconda Canada Exploration Ltd staked Thor cl 1-192 (YA32315) on the west side of the remaining Walker claims (1-4). The company explored with soil sampling, mapping and EM surveys later in 1979 and 4 holes (1 000 m) in 1980. The Thor claim block was subsequently restaked as Roth cl 1-20 (claim numbers unknown) but these were allowed to lapse without further work.
Total Erickson Resources Ltd surrounded the remaining 4 Walker claims with Tooth cl 1-180 (YB17966) in Sep/88. In spring 1989, Total Erickson changed its name to Total Energold Corp and carried out geological mapping, soil sampling and geophysical surveys later that year.
S. Ridgway fringe staked to the south and west with 114 Dar cl (YB39844) in Jan/91.
In Oct/94 Kennecott Canada Inc surrounded the 4 remaining Walker claims with the Am cl 1-120 (YB52734). In Jul/95 the company added AM cl 121-126 (YB53972). In the summer of 1995 Kennecott carried out detailed geological mapping and rock, soil and stream sediment sampling on the AM claims. Kennecott continued exploring various parts of its claim block in 1996 and 1998.
Capsule Geology
Pyrite, galena, arsenopyrite and chalcopyrite occur in tourmaline-bearing quartz and quartz-carbonate veins (locally called the Walker vein) near the margin of the composite Mid-Cretaceous Antimony Mountain syenite to quartz- monzonite stock. Sedimentary rocks of the Late Proterozoic-Early Cambrian Hyland Group and the Ordovician to Lower Devonian Road River Formation are intensely silicified and pyritized adjacent to the intrusion, and locally contain patches of intense sericitization.
The original showing located on Antimony Mountain consists of crystal aggregates and pods of stibnite up to 25 cm thick, erratically distributed with quartz through an aplite or rhyolite dyke that cuts the syenite stock near its contact with hornfelsed Road River Formation rocks. The dyke strikes northeast, dips steeply southeast and has been traced for 460 m. Considerable disseminated pyrite occurs near the intrusive contact.
Each company that has worked in the area has taken a cursory look at the Walker vein but very little new exploration has occurred since the 1970's. To the west (Minfile Occurrence #116B 095), Anaconda located eight quartz veins containing pyrite, arsenopyrite, pyrrhotite and minor chalcopyrite and sphalerite. These veins cut a sequence of Proterozoic to Lower Cambrian Hyland Group sedimentary rocks which are repeated by thrust faulting near the margins of the syenite stock. The veins are up to 1 m wide and tens of metres long, and returned assays as high as 10% Cu, 3% Pb, 2.5% Zn, 300 g/t Ag and 30 g/t Au. In 1989 Total Energold re-mapped and sampled five of the more significant arsenopyrite-pyrite-tourmaline -quartz-calcite veins found by Anaconda.
Kennecott staked their claims to evaluated the bulk tonnage gold potential of the stock and surrounding country rock. Kennecott¿s maps show the Walker vein but did not examine it. Both Energold and Kennecott collected a large number of stream sediment and soil samples from areas surrounding the Walker claims and numerous spot anomalies were reported. Follow up work failed to uncover any new showings on or near the Walker claims and Kennecott focused their efforts towards veins and showings located at neighboring Minfile Occurrences #116B 094 and 095.
