The Bon Diable showing is located 6 kilometres northeast of Vernon, northwest of BX Creek.

In the area, east of the Okanagan Valley fault zone, Upper Triassic to Lower Jurassic Nicola Group sedimentary and volcanic rocks and gneissic rocks of unknown age are faulted over metasedimentary rocks of the Proterozoic Silver Creek Formation. Jurassic granitic dikes cut the older rocks.

In an area of dikes, faulted quartzites of the Silver Creek Formation host gold, silver and copper mineralization in quartz veins. Several small quartz veins and irregular bodies carry spotty free gold and malachite staining. The main vein is 0.9 metre thick and is faulted off at depth. The vein strikes 020 degrees and dips 75 degrees west.

Initial sampling assayed up to 320 grams per tonne gold although average grades are low. A 1-tonne shipment in 1899 produced 498 grams of silver.

Exploration is first mentioned in 1895 and by 1901 a 12-metre shaft, with about 30 metres of underground working had been completed.
