Capsule Geology

The Jack Pot showing is located on Eagle Creek, about 7.5 kilometres west of Nelson. Old prospect tunnels and adits are present on the property.

The area is underlain by Jurassic pseudodiorite and pyroxenite of unknown affinity. Middle to Late Jurassic Nelson intrusions and volcanic rocks of the Lower Jurassic Elise Formation (Rossland Group) occur to the east and west.

A quartz vein carrying pyrite and chalcopyrite is hosted by psuedodiorite and siliceous granite (?). The quartz material contains limonite and malachite staining and assays of selected samples reported in 1919 indicate 2.8 per cent copper, 34.3 grams silver and 1.37 grams of gold (Minister of Mines Annual Report 1919, page 133).

It is believed that the showing is an extension of the Hardscrabble vein (082FSW086) which formed part of the Granite- Poorman deposit immediately to the north.
