The Western Trenches showing is about 500 metres southwest of Saskat Creek and 1.9 kilometres northwest of the confluence of Siwash and Tepee creeks.

Lead-zinc-silver mineralization occurs in siliceous zones and in quartz veinlets in the vicinity of the contact between quartz-feldspar-biotite porphyry and strongly kaolinized and silicified granite, both of the early Tertiary Otter intrusions. Fracture fillings and veinlets of hematite accompany this mineralization. In addition, magnetite and lesser pyrite and minor chalcopyrite are localized along a network of northeast and northwest striking basaltic dikes. A sample from a quartz vein, 5 to 15 centimetres wide, assayed 0.41 to 0.80 per cent zinc, greater than 34 grams per tonne silver and greater than 0.8 per cent lead (Assessment Report 7992, part 3, page 11, rock geochemistry maps).

In 1980, drill hole SS-80-14, located approximately 500 metres to the east of the trenches, yielded intercepts of up to 0.13 gram per tonne gold, greater than 50 grams per tonne silver and 1.13 per cent copper over 1.5 metres (Besserer, D.J. (2007-05-27): Technical report on the precious and base metal potential of the Siwash Creek Property).

In 2006, two samples (06KRP414 and 06KRP 415) yielded values of up to 0.42 gram per tonne gold, 32.5 grams per tonne silver, 0.47 per cent zinc and 0.15 per cent lead (Besserer, D.J. (2007-05-27): Technical report on the precious and base metal potential of the Siwash Creek Property).

The area has been explored in conjunction with the nearby Snowstorm (MINFILE 092HNE032) occurrence and completed exploration history can be found there.
