The Jo showing is located on the crest of a small north-trending ridge approximately two kilometres west of Red Mountain and 1.5 kilometres south of Frederickson Creek.

Red Mountain is underlain by rusty red weathering, pyritic andesite to basalt flows and related sills of probable Late Cretaceous to Tertiary age. These rocks sit with angular discordance on intensely folded Paleozoic carbonates. Outcrops of carbonate form rounded crests of serveral north-trending hills on the west slope of the mountain. A northwest and north-trending sware of dikes, sills and plugs of basalt, diorite and quartz monzonite porphyry cuts the carbonates.

The Jo showing is a disseminated bornite skarn developed near the contact of a diorite plug. Several small pits probably record exploration work at the showings many years ago. Three samples collected by Geddes Resources Limited in 1990 contained 0.7 to 1.18 per cent copper and 5.9 to 7.0 grams per tonne silver and up to 0.18 per cent zinc. A grab Sample collected during a brief stop at the showing assayed 1.20 per cent copper and 8 grams per tonne silver.
