The Paso (Road Cut) occurrence is located south of the Soo River, near the Soo River forest service road and approximately 1.5 kilometres northwest of Showh Lakes.

The area is underlain by a northwest trending roof pendant composed of andesitic volcanic rocks of the Lower Cretaceous Gambier Group and volcaniclastic rocks of the Upper Triassic Whistler Pendant. Pendant rocks dip moderately to steeply to the east and are interpreted to be an overturned sequence. These are enclosed by quartz dioritic rocks of the Jurassic to Cretaceous Coast Plutonic Complex.

Locally, a diorite, exposed along a logging road, hosts a number of narrow, less than 10 centimetres wide, pyrite-chalcopyrite veins.

In 1989, a sample (SR89-005) assayed 0.16 gram per tonne gold, 56.1 grams per tonne silver and 5.25 per cent copper (Property File - A. Davidson [1989-06-14]: Re: Property Exam - Soo River, Whistler Area).

In 1989, the area was prospected, sampled and trenched as the Soo River property.
