The Jackpot West prospect is located on the ridge between Hidden and Porcupine creeks, 10 kilometres northeast of Salmo. See also Jackpot Main (082FSW012), Jackpot East (082FSW013) and Jackpot Lerwick (082FSW256).

The Jackpot orebodies are currently thought to be Kootenay Arc-type carbonate hosted sedimentary exhalative (sedex) deposits. The orebodies are located within dolomitized limestone of the Lower Cambrian Laib Formation, Reeves Member (correlative with limestone of the Badshot Formation). The carbonate is complexly folded and faulted close to the north margin of the granitic Hidden Creek stock of the Middle to Late Jurassic Nelson Intrusions.

Mineralization on the Jackpot West zone occurs near the base of the dolomite along the northwest margin of a large unit of limestone which strikes northeast and dips south. The mineralized zone has a maximum width of 2 metres and has been traced along strike for about 138 metres. Sphalerite and pyrite occur in banded serpentinized dolomite, and locally sphalerite and minor galena are found in a diopside skarn. The zone is discordant to the northeast with metasediments of the Lower Cambrian Quartzite Range and Reno formations and is likely in fault contact with them. To the southwest the mineralized dolomites are cut by a north trending fault. For reserves and work history refer to the Jackpot Main (082FSW012) occurrence.

Tombstone Explorations Co. Ltd. acquired the Jackpot property from New Jersey Zinc Explorations Company (Canada) Ltd. in 1997.
