The Yellow Moose property comprises two known showings, the Gus and Arrow. All occur south of Arrow Lake, approximately 9 kilometres west of Kenney Dam, and are accessible by logging roads to within approximately 1 kilometre. The showings are marked by anomalous antimony, arsenic and mercury soil anomalies.

The property is underlain predominantly by Late Cretaceous-Eocene Ootsa Lake Group felsic volcanic and related sedimentary rocks. Miocene Endako Group basalt unconformably overlies these rocks and occurs throughout the region along major valleys and in areas of high relief. Basement rocks, consisting of Jurassic Hazelton Group andesitic volcanic rocks, are exposed west of the property and are intruded by quartz monzonite stocks of Cretaceous or Tertiary age.

The Arrow showing, located on the south shore of Arrow Lake, consists of drusy quartz veins and chalcedonic quartz flooding in siliceous rhyolite and arkosic sandstone. Mineralization consists of coarse-grained stibnite, pyrite, marcasite and traces of cinnabar.

The Gus showing consists of diffuse silicification and minor quartz chalcedony veining in brecciated rhyolite and crystal lapilli tuff. Mineralized zones trend northeast and consist of narrow veins, stockworks and breccias. Mineralization consists of 1 to 2 per cent fine-grained disseminated arsenopyrite, stibnite and pyrite in intensely fractured and pervasively clay-altered rhyolite.

Work History

The first major geological survey conducted in the region was by H.W. Tipper of the Geological Survey of Canada between 1949 and 1953 (GSC MEM 324).

The Yellow Moose claim area was first staked by Newmont Exploration of Canada in 1987 when stibnite-bearing boulders were traced up-ice to their apparent source on the shore of Arrow Lake. During 1988 and 1989, Newmont explored their claims with mapping, sampling and geophysical surveys (Assessment Report 18191). Hand trenches revealed erratic gold mineralization (up to 0.8 gram per tonne) with variable amounts of pyrite, arsenopyrite, stibnite, cinnabar and marcasite in silicified breccia structures showings near the south shore of Arrow Lake.

In 1992, Cogema Resources Inc. staked the Yel 1 to 9 claims over and along strike of Newmont's showings. During 1993, Cogema flew an airborne EM/magnetic survey (Assessment Report 23099), located three additional showings and delineated several areas with anomalous till geochemistry (Assessment Report 23387). The Yel 10 and 11 claims were staked in 1994 to extend the property to the east. Six inclined diamond drill holes (626 metres) were collared during 1994 to test two mineralized zones coincident with geophysical chargeability anomalies (Assessment Report 23748).

In 1995, Phelps Dodge Canada optioned the Yel 1 to 11 claims from Cogema and continued exploration with soil and rock sampling, prospecting and geological mapping (Assessment Report 24766). The 1995 exploration program was designed as a follow-up to Cogema’s 1994 field season (Assessment Reports 23099, 23387, 23748) to evaluate areas of anomalous high resistivity outlined by a previous airborne survey on the property. A total of 1009 soil samples were collected over areas of interest and outlined coincident east-west trending arsenic and mercury soil anomalies through the central part of the property however anomalous gold values within this area are only weakly anomalous and irregularly distributed. A total of 159 rock samples were collected throughout the property with moderate to strongly anomalous arsenic values ranging up to 0.59 per cent arsenic and mercury values up to 14 parts per million (Assessment Report 24265). Gold values were uniformly low with the highest value of 0.654 gram per tonne gold from a silicified lapilli tuff breccia with quartz/chalcedony veinlets (Assessment Report 24265). All rock samples weakly anomalous in gold are related to a fault structure within an extensive argillically altered envelope.

In 1996, an IP survey was conducted by Phelps Dodge Corporation of Canada, Ltd. over 12.6 kilometres (Assessment Report 24766). The IP/resistivity survey of the Arrow Grid East detected the "Arrow" showing with a possible extension. Three other IP anomalies were also occur and are similar to the IP anomaly over the showing. The Arrow West Grid data describe four lithologies with differing electrical properties and one IP lithological unit.

In 2016 and 2017, John Kreft completed programs of biogeochemical and geochemical (rock, soil and till) sampling on the area. A grab sample (BYMR-03) of brecciated rhyolite yielded 0.18 gram per tonne gold (Assessment Report 36657).
