The Kozij occurrence is located south of the Soo River, at an elevation of approximately 900 metres and approximately 4 kilometres west 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, two trenches expose chlorite-sericite altered intermediate volcanics hosting fine grained pyrite and galena with minor chalcopyrite.

In 1989, a sample (SR89-001) assayed 0.82 gram per tonne gold, 7.2 grams per tonne silver, 0.642 per cent lead and 0.701 per cent zinc (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.
