The Pakk 1 occurrence is located near the junction of the two main arms of Jack Creek, an east flowing tributary of Hellroaring Creek, at an elevation of approximately 1500 metres.

The area is underlain by quartzite, wacke, argillite and siltstone of the mid-Proterozoic (middle) Aldridge Formation (Purcell Supergroup), intruded by meta-gabbro or meta-diorite of the Proterozoic Moyie Intrusions.

Locally, at surface, a zone of albite alteration hosts galena mineralization. Diamond drilling has identified a gabbro with silicified and albitized sediments hosting minor quartz veinlets with galena and sphalerite mineralization. Concentrated irregular bands of pyrrhotite were also reported in the drill hole.

In 1993 and 1994, Cominco completed 36.6 line-kilometres of electromagnetic surveying on the area as the Roar claims. In 1999, Chapleau Resources Ltd. completed a single, 535.7-metre, diamond drill hole (P99-9) in the area.
