The Golden West showing is located 2.75 kilometres southeast of Burnell Lake and 2.5 kilometres northwest of Oliver, British Columbia.

In 1989, Gila Bend Resources Corp. made a 50 per cent option agreement with Golden Web Resources Ltd. on the ground covering the Golden West showing. Golden Web Resources Ltd. had optioned the claims covering the Golden West showing from Hiburd Properties Ltd.

Regionally, the area is principally underlain by medium grained intrusive rocks that form the Jurassic Oliver plutonic complex. To the south, the complex cuts Carboniferous to Permian Kobau Group metasedimentary rocks. On its northern margin, the intrusive mass is in contact with Eocene volcanics and sediments of Penticton Group.

The geology surrounding the Golden West showing area is composed almost entirely of quartz monzonite of the Oliver plutonic complex. Three distinct phases are evident. A central core of massive medium-grained garnet-muscovite quartz monzonite is surrounded by biotite-hornblende quartz monzonite north of the core and porphyritic biotite quartz monzonite to the south. Hornblende diorite occurs in several small areas to the immediate north.

The Golden West showing is hosted by the hornblende-bearing porphyritic quartz monzonite phase of the Oliver plutonic complex. Fine to medium grained quartz monzonite dike swarms locally cut this unit. The area has been extensively faulted and fractured. Regional hydrothermal alteration has resulted in epidote which occurs in seams up to 2.5 centimetres in width.

In 1989, an old adit and quartz vein were discovered. The vein is approximately 0.60 metre wide, strikes 065 to 070 degrees and dips steeply southeast. No visible mineralization was noted in the vein but several samples taken from this quartz vein yielded high precious metal values. The highest was Sample S2, a grab sample from the west side of the vein which yielded 3.8 grams per tonne silver and 0.14 gram per tonne gold (Assessment Report 18397).
