The Jo Dandy occurrence is located at 994 metres elevation, 2.5 kilometres west of Westbridge. The Jo Dandy occurrence was part of a claim block that consisted of the Jo Dandy (Lot 2120), Old Kentucky (Lot 2121), Emma Fr. (Lot 2122), Riley (Lot 2123), Texas Fr. (Lot 2124), (Lot 2125), Long Shot (Lot 2451) and Duff (Lot 2452) Crown-granted claims. Records indicate that the Jo Dandy and Old Kentucky claims received the majority of exploration and development.

The area is underlain by metasediments and metavolcanics of the Permian to Carboniferous Anarchist Group. Host rock of the Jo Dandy occurrence is highly metamorphosed schist that has been highly serpentinized. The schist strikes 180 degrees and dips 20 degrees to the west. Argillite is also locally present. These are overlain by a quartz feldspar porphyry sill. An intrusive dike crosscuts the schist 30 metres from the shaft. Mafic volcanics have been mapped as the host rock on the Old Kentucky claim. These are overlain by volcanics of the Penticton Group. Volcanics include amygdaloidal flows, pyroclastic equivalents and quartz feldspar porphyry.

Locally, on the Jo Dandy and Old Kentucky claims, quartz or quartz-calcite veins, 1 to 200 centimetres in width, host stringers, lenses and disseminations of pyrite, galena, sphalerite and lesser chalcopyrite. Ribbon textures were noted in quartz veins and brecciation of volcanic wallrock has locally occurred.

In 1927, samples taken from the Jo Dandy claim on different parts of the upper and lower tunnels, yielded trace to 1.7 grams per tonne gold, 48 to 65 grams per tonne silver, 4 to 10 per cent lead and 2 to 11 per cent zinc (Minister of Mines Annual Report 1927, page 234).

Sampling in 1983 from the west trench of two trenches adjacent to the gloryhole on the Old Kentucky claim revealed the following assay results. Sample D from the south wall of the west trench yielded 1.37 grams per tonne gold, 19.9 grams per tonne silver, 0.23 per cent lead and 5.6 per cent zinc over 1.0 metre, while sample E, from the north wall, yielded 1.37 grams per tonne gold, 25.37 grams per tonne silver, 0.15 per cent copper, 0.24 per cent lead and 4.1 per cent zinc over 1.5 metres (Assessment Report 11569).

Exploration and development work on the Jo Dandy occurrence dates back to 1902, when the Jo Dandy and Old Kentucky claims were Crown- granted to L.S.M. Barrett. By 1926, the property had been Crown- granted to A. Mellor. Under his ownership, development on the Jo Dandy consisted of 10.6-metre deep shaft, a 22.9-metre crosscut tunnel with a 14.6-metre long open-cut approaching it, and a 9.1-metre tunnel 6.1 metres deeper in the shaft. Little else was done on the Jo Dandy until Canadian Exploration took an option from L. Long and M. Wiley in 1952. Trenching and geological mapping revealed disappointing results and the option was dropped in the same year.

In 1983, Quinella Exploration Ltd. conducted programs of geological mapping, prospecting, soil and rock sampling and ground geophysical surveys on the area as the Rock claim. Previous trenching and diamond drilling of unknown age was identified at this time, along with two correlative geochemical soil and geophysical anomalies (A and B), covering an area 700 by 350 metres, that included the Old Kentucky workings. In 1984, Westbridge Resources completed a program of soil sampling and ground geophysical surveys on the area.
