The Joint vein is an east-west trending quartz vein within limestone of the Lower to Middle Ordovician Active Formation. The limestones and argillites of the Active Formation are in fault contact with Lower Cambrian Laib Formation sediments to the east and host a stock of Middle to Late Jurassic Nelson Intrusions southwest of the occurrence.

Mineralization consists of minor disseminated galena, sphalerite, and pyrite in quartz gangue. Both walls of the vein contain minor streaks of limonite and have spotty gold and silver values over narrow widths.

In late 2016, Margaux Resources Ltd. optioned the property and in 2017 examined the area. A grab sample (SC17-BL06) from a dump located near the Joint adit portal assayed 12.08 grams per tonne gold, 545 grams per tonne silver, 10.50 per cent lead and 13.62 per cent zinc, while two grab samples (SC17-BL07A and B) from a dump located near the Joint shaft yielded 21.80 and 3.09 grams per tonne gold, 1021 and 19.29 grams per tonne silver, 33.68 and 0.500 per cent lead with 9.84 and 11.38 per cent zinc, respectively (Lane, R.A.
