Work History

Staked as Great Northern cl (174) in June, 1899 by W.F.D. Cummings and re-staked as Bald Eagle (4465,371A) in August, 1900 and Dunsmuir cl (6553) in January, 1903 by A. Robertson. Robertson explored with a 50 m shaft and 54 m of drifting on two levels in 1901-1906. Three claims were later surveyed and taken to lease. Several other claims were staked nearby at this time, including the Nugget cl and Skukum Ledge cl. These claims were also explored with shallow shafts and trenches, including a 20 m shaft on the Skukum Ledge cl and 20 and 25 m shafts on adjoining claims.

Re-staked as Syndicate cl (YA79246) in September, 1983 by Can Longhorn Pet L, which performed geochemistry and EM surveys in 1983 and drilled 5 holes (371 m) in 1984. The adjoining Plinc cl (YA84100) and Sury cl (YA88123), staked by the Dawson Syndicate on the west side in June, 1984, and '98' cl (YA79549), staked by H.L. Corp and Dawson Syndicate in September, 1983, were explored with geochemistry and airborne EM surveys and mapping in 1984. Can Longhorn Pet changed its name to Can Ferrite Corp. in 1984. Similar grid surveys were performed on the Syndicate and '98' groups in 1986. Dawson Syndicate mapped and sampled on the '98' claims in 1988.

In fall, 1990, a joint venture group consisting of Arbor Resources Inc. and Faith Mines (Syndicate claims) and Appian Resources and Klondike Reef Mines ('98' claims) conducted IP and resistivity surveys on the southeast boundary of the Syndicate and '98' claims. Arbor trenched on the '98' claims and on the Syndicate 56 claim in 1991 and Hastings Management Corp. trenched on the Sury claims in 1992.

Kennecott Canada Inc. optioned the property in November, 1992, and in August, 1993, performed prospecting, rock and soil geochemical sampling, geological mapping and reprocessed the Dawson Syndicate's 1987 airborne geophysical data. In January, 1995 the '98' claims were transferred to Arbor Resources Inc. In 1996, Arbor Resources changes corporate name to Klondike Gold Mining Corp.

Capsule Geology

The area is underlain by rusty muscovite-quartz schist (unit Psqm) and quartz and feldspar augen-bearing quartz-muscovite schist (unit Psa) of the Permian Klondike Schist Assemblage. Isotopic age determinations indicate a middle Permian (261-263 +/- 4 My) crystallisation age for unit Psqm (Mortensen, 1996).

Early exploration concentrated on a southwest-dipping quartz vein reported to be at least 2.4 m thick. No assay data is available for the showing.

The GSC recognized cerussite in pan concentrates from Adams Creek upstream from the shaft and reported that quartz-barite veins were found by placer miners nearby. Samples from two 3 m wide quartz veins on the Nugget cl on Little Skookum Gulch were reported to assay as high as 68.6 g/t platinum.

The 1983 staking was based on anomalous gold values in heavy mineral concentrates associated with a strong 1.2 km long EM conductor. The 1984 drilling intersected chlorite-quartz-sericite schist with narrow graphitic bands and disseminated pyrite.
The 1990 geophysical survey tested IP and resistivity responses in an area of known placer potential. A 1 m chip sample taken across a contact between graphite schist and quartz augen schist in Trench 91TR11 on the '98' claims assayed 0.69 g/t Au.

In 1992, backhoe trenching on the Sury claims exposed fresh, unaltered quartz-augen schist. Soil geochemistry conducted in 1993 by Kennecott outlined base and precious metal anomalies on the Sury and Dawson claims.
