Work History
Originally staked as Donjek cl 1-16 (63435) in Aug/52 by Conwest Exploration Company Ltd. Teck Exploration Company Ltd staked Musketeer cl 1-24 (63307) to the east and west at the same time. In 1953 both companies are reported to have carried out geological mapping and prospecting, as well as staking Donjek cl 17-27 (66049) and Musketeer cl 25-52 and 64-67 (66166) in Jul/53 and Musketeer cl 53-62 (66479) in Aug/53 contiguously with the original claims. In 1955, Teck carried out magnetometer, EM and resistivity geophysical surveying of the combined claim group and staked Ohm cl 1-4 (71070) to the southeast in Aug/55.
Restaked as Legacy cl 1-24 (Y12572) in Apr/67 by J.B. O¿Neil and C. Gibbons, who carried out magnetometer and EM-16 geophysical surveying and geological mapping of the claims later in the year in conjuction with work on their adjoining Jiffy and Tippy claims to the southeast (Minfile Occurrence #115G 025) which included road building. Optioned briefly in Feb/72 to the Nickel Syndicate (Canadian Superior Exploration Ltd, Aquitaine, Home Oil Company Ltd and Getty Mines Ltd), which carried out geological mapping, geochemical sampling, magnetometer and EM surveying later in the year.
Restaked as Mus cl 1-16 (YA94962) in Jun/86 by Kluane Joint Venture (All-North Resources Ltd and Chevron Minerals Ltd), which carried out geochemical sampling in 1986. G. Davidson staked Amp cl 1-10 (YA95100) to the southeast at the same time, before subsequently optioning the claims to Kluane Joint Venture which drilled one hole (85.6 m) 2.35 km southeast of the location marker for this occurrence in 1988.
The Oro cl 1-12 (YA96419) were tied on to the north by E. Parmentier in Nov/86 and sold to Fred Minerals Ltd in 1987. Other adjoining claims included Missy cl 1-28 (YA97660) and SF cl 1-84 (YA97576) to the southwest in Jun/87 by Harjay Exploration Company Ltd and Kluane Joint Venture; Jek cl 1-48 (YA96984) to the west in Mar/87 by Silverquest Resources Ltd and Pak-Man Resources Inc, which carried out geological mapping and geochemical sampling later in the year; and PC cl 1-50 (YA97796) to the south in May/87 by S. Ridgway.
In 1987 the Kluane Joint Venture claims were optioned by Rockridge Mining Corporation and Pak-Man Resources Inc, which carried out geological mapping, geochemical sampling and magnetometer and VLF-EM surveying later in the year. The PC claims were transferred to Gold City Resources Inc in Jun/88 and a 50% interest in the Oro claims was transferred to A-X Minerals in Oct/88. Harjay explored the SF and Missy claims with soil geochemical sampling and magnetometer surveying in Jun/88 and Jun/89.
Restaked as Ar cl 1-60 (YC18359) in Sep/99 by Cabin Creek Resources Management Inc (T. Morgan) which added Ar cl 61 (YC18892) in Sep/2000, before optioning the claims to Auterra Ventures Inc in Oct/2000. Auterra carried out geochemical sampling, road rehabilitation and blast trenching in 2000 and geochemical rock sampling and magnetometer and VLF-EM geophysical surveying in 2001.
Capsule Geology
Assessment work filed from 1953 to 1955 identified two small copper-nickel showings that were found on the Donjek cl 4 (Conwest showing, this occurrence) and approximately 1 km south on the Musketeer cl 32 (Teck showing). The area is largely drift-covered, but mapping and geophysics revealed that conformable Lower Triassic mafic to ultramafic sills are present in the Pennsylvanian to (?) Lower Permian Station Creek Formation which underlies the area and is comprised of intermediate to mafic volcanics and sediments.
No nickel mineralization was found during the earlier work, but Station Creek tuff containing disseminated and fracture filling chalcopyrite and malachite assayed up to 0.3% Cu.
The Conwest showing consists of 90 m of oxidized, medium grained gabbro lying east of and subparallel to a south-southeast trending fault. The intrusion occurs as two separate bodies, 15 m or more in width, that are flanked by quartz +/- calcite stringer stockwork zones within the volcanic host rock. Both the intrusion and stockwork zones are mineralized with interstitial and disseminated pyrite and chalcopyrite +/- pentlandite. Chip sampling in 2000 returned values up to 2 015 ppm Ni, 5 448 ppm Cu and 154 ppb Au.
The Teck showing consists of a small exposure of a 1 m wide, southeast trending fault zone within variably calcareous felsic to intermediate feldspathic porphyry in proximity to a peridotitic sill. The fault zone is mineralized with pyrite, while the sill is locally serpentinized and variably mineralized with fine disseminated pyrite, magnetite and pyrrhotite. Chip samples collected from a carbonate altered section of the sill returned the best values from sampling of this showing, returning 0.11 g/t Pt, 0.11 g/t Pd, 1 581 ppm Ni, 709 ppm Cu and 0.14 g/t Au over 2 m.
Magnetometer surveying in 2001 identified anomalies in overburden covered areas in the vicinity of the Teck showing and the 1988 drill hole (DDH A-88-01). The anomaly in the vicinity of the Teck showing is located approximately 60 m northwest of the showing and measures 150 m along strike by 100 m wide and is open along strike in both directions. The anomaly in the vicinity of DDH A-88-01 is atleast 475 m long, varies in width from 30 to 150 m and is coincident with the axis of a relatively continuous VLF-EM conductor along its southeast edge.
