Fine to medium grained quartz feldspar granitic pegmatites are interlayered with biotite-quartz-feldspar gneiss of the Precambrian- Paleozoic(?) Monashee Complex. Foliation of the gneiss strikes 080 to 100 degrees and dips 10 to 30 degrees north. Some of the pegmatites crosscut the gneiss as dikes and sills, however, the largest pegmatites are conformable lenses with thicknesses to 5 metres and strike lengths to 70 metres.

Radioactivity is associated with the granitic pegmatites, with anomalous zones up to several metres long and a few centimetres wide. Mineralization consists of uraninite crystals and fluorescent lemon- yellow to green autunite smears on fractures.

At the Cran 3 showing, a chip sample from pit #2 assayed 0.08 per cent uranium (Assessment Report 6816). The pegmatite is comprised of coarse-grained quartz, feldspar and biotite with several biotite clots. Several radioactive zones, with supporting uranium assays, occur over an area up to 2.5 kilometres southeast of pit #2.
