Work History
Staked as Fog cl (YA95070) in Jul/86 by Kerr Addison, which conducted geological and geochemical surveys that year and geological, geochemical and geophysical surveys in 1987.
Since 1987, soil and rock sampling has been carried out in the vicinity of the Fog occurrence.
Capsule Geology
The Fog property is dominantly underlain by Early Cretaceous Whitehorse Suite granodiorite. Small rhyolite to granite plugs and quartz-feldspar porphyry dykes intrude the older granodiorite. These dykes and plugs may be associated with a north-trending feldspar porphyry dyke swarm mapped approximately 450 m west of the property. Localized bodies of andesitic tuff and pyroclastic rock occur in the northern and southern parts of the property. The southern andesites display strong bleaching and transitionally grade into unaltered Carmacks Group augite olivine basalts, further to the south (Pautler, 1986).
Two main vein zones and numerous minor veins have been identified. The Fog vein consists of quartz vein float scattered over a 300 by 30 m area which produced assays up to 2 g/t Au and 4.3 g/t Ag from specimens. Vein 2 lies southwest of the Fog vein. It appears to be 500 m long and 0.5 to 2 m wide but so far has produced low gold values.
