The area is within the Precambrian-Paleozoic(?) Shuswap Metamorphic Complex and underlain by a sequence of quartzite, calcsilicate and pelitic gneiss, marble and amphibolite that trends generally northward and dips at various angles to the east. A pronounced foliation, essentially parallel to layering, suggests that the apparently simple homoclinal sequence that hosts the mineral occurrence is, in fact, part of a complex, isoclinally folded metasedimentary package.

The D.S. (Rebar) showing is a rusty-weathering layer of calcareous quartzite a few metres thick that is exposed in a logging roadcut. The layer trends east and dips north at 10 to 15 degrees. Subrounded grains of galena and sphalerite are disseminated through the layer and irregular grains are interstitial to a mosaic of angular quartz grains. Scattered grains of diopside, biotite partially altered to chlorite, and barite are common in the quartzite. The quartzite layer is underlain by interbedded feldspathic quartzites and calcsilicate gneiss layers, and overlain by a rusty, impure siliceous marble and calcsilicate gneiss sequence.
