Capsule Geology

The Partridge showing is located on a ridge separating the Partridge River and Radelet Creek, approximately 2.5 kilometres south of the British Columbia-Yukon border.

The oldest rocks in the region are predominately quartzites, mica-feldspar-quartz schists and gneisses of the Yukon-Tanana Terrane. These rocks occur in a northwest trending belt of roof pendants and xenoliths surrounded by granodiorite, quartz diorite, quartz monzonite and granite of the Coast Plutonic Complex. The metamorphic rocks are thought to be early Paleozoic in age while the plutons are dated as Cretaceous to early Tertiary.

Locally, the area is underlain by equigranular, coarse grained biotite-hornblende quartz monzonite.

Mineralization occurs in a 1 to 10 centimetres wide quartz vein that strikes 000 degrees and dips 85 degrees west. The vein contains a breccia mix of bismuthinite, chalcedony and up to 10 per cent fluorite. Samples of different types of veins and altered wallrock, all yielded near background values.

In 2007, Strategic Metals Limited completed an exploration program of geological mapping, prospecting and soil geochemical sampling. Eight rock and 22 soil samples were collected.

In 2012, Brad Wilson prospected the area. He described a pronounced nearly north-south trending linear depression. The linear feature is visible on air photos and on satellite-view on Google Maps. It is an approximately 1 kilometre long, 5 metres wide, flat, debris filled depression with a trend of 005 degrees. Outcrop was not found in any part of this feature in 2012. A few soil and rock samples were taken in the area.
