Work History
Staked as CC cl 1-30 (YB89112) in Apr/97 by Fairfield Minerals Ltd, which carried out geochemical sampling and flew an airborne geophysical survey over the claims, before adding CC cl 31-44 (YB89977) in Sep/97. A ground IP geophysical survey was carried out in the fall of 1997 to test the subsurface extent of alteration and mineralization discovered in the main gossan area. In 1998, Fairfield carried out soil sampling and prospecting and staked CC cl 45-54 (YB91616) in Sep/98. The claims were optioned to Brett Resources Inc in 1999, which carried out geological mapping that year.
Capsule Geology
The area is located in the southeastern portion of the Teslin (105C) topographic map sheet. Geologists employed by the Ancient Pacific Margin NATMAP project; a projected jointly funded by the Geological Survey of Canada, the British Columbia Geological Survey and the Yukon Geology Program, are presently re-mapping the area, including the rocks in the occurrence area. Exploration interest in the region has recently risen as most of the rocks appear similar in age (Devonian ¿ Mississippian) and lithology to those hosting volcanogenic massive sulphide mineralization in the Finlayson Lake district.
The occurrence is located between the Big Salmon Complex to the west and the Cassiar Platform to the east and is underlain by a succession of mafic to intermediate volcanic and epiclastic rocks assigned to the Klinkit Succession. Recent age dating by Mortensen and Gabites (2002) has resulted in a Pennsylvanian age date for the Klinkit Succession. The Klinkit Succession rocks interfinger with and overlie the Screw Creek limestone and is unconformable overlain by Late Triassic, thin-bedded clastic rocks containing minor chert and limestone belonging to the Teh Formation. Mid-Cretaceous age plutons commonly intrude the sequence. Roots and et al., have recently assigned the Klinkit Succession to the Yukon-Tanana Terrane.
Prospecting identified several areas where gossanous schist layers were found. Follow-up soil sampling identified 2 main multi-element soil anomalies centred over the Discovery and the Claim Post showings. The Discovery showing (this occurrence) is a Cu, Pb and Zn anomaly nearly 1 km long and several hundred metres wide. Ag is slightly elevated and coincident with the base metals. Blast trenching in 1998 outlined at least 2 distinct rusty pyritic, quartz-sericite schist horizons that trend northeast parallel to foliation. Chip and grab samples were not anomalous in base metals.
The Claim post showing (located 1.5 km to the north) consists of anomalous Au values and spotty Cu, Pb and Zn values. Trenching exposed at least three similar horizons, none of which measured more than a few metres thick. Samples taken from blast trenches returned up to 338 ppb Au, 4 ppm Ag, 761 ppm Cu, 96 ppm Pb and 96 ppm Zn. The showing appears to trend in the same direction as the Discovery showing but appears to lie stratigraphically above it. The geophysical programs did not return any significant anomalies.
