The Hoodoo West occurrence is situated in an area where numerous small plutons are separated by Paleozoic to Mesozoic stratified rocks. The property is underlain by both intrusive and stratified rocks with areas to the south and west becoming dominantly intrusive while stratified rocks continue to the northeast. Locally, three groups of bedded rocks have been recognized, all of which have been cut by intrusives. The oldest rocks consist of schistose basaltic to rhyolitic pyroclastics, sediments and limestones. The second unit is made up predominantly of thin-bedded cherts with minor siltstone. Quartz-pyrite fracture fillings do occur within this unit. The third unit consists of well-bedded coarse to fine volcaniclastics, sediments and, possibly, minor flows. Intrusives noted include quartz monzonite, biotite granodiorite, hornblendite, fine-grained feldspar porphyry diorite and a quartz-eye felsite.
Minor copper and molybdenite mineralization occurs in a quartz stockwork within a quartz monzonite intrusive. A large gossanous zone of intense argillic alteration within the quartz monzonite yielded subanomolous values of arsenic and antimony.
The Hoodoo West claim group was staked in 1983 for Kerr Addison Mines Ltd and the work followed in the same year consisting primarily of prospecting and sampling with minor geological mapping and hand trenching. Seventeen soils and twenty-seven rock samples were collected and analyzed for Au, Ag, As and Sb. Some of the samples were also run for Ba, Hg, Cu, Zn and Pb. Geology was recorded at sample sites and plotted on 1:1O OOO scale map.
In 1991, an airborne geophysical survey consisting of 320 line kilometres was carried out on behalf of Galico Resources Ltd by Aerodat Limited (Assessment Report 21655) over the Wiseguy property consisting of the S&G and Guy claims. The area flown covers the Heather Vein (104B 130) and Hoodoo West 6 (104B 283) MINFILE occurrences. Geophysical data suggest that the unit is broken by a series of northeast oriented faults. Magnetic, VLF-EM and possibly conductive trends of a northwesterly orientation were distinguished.
