The property is located on the south side of Porcupine creek some 7 kilometres southeast of Ymir.

The showings were discovered in the late fall of 1927 by J. Thexton, who staked the Rainy Day, Lucky Sunday and Success claims. Work by the owner in 1928 included trenching and driving three short adits.

New Jersey Zinc Exploration Company (Canada) Ltd, which acquired the nearby Jackpot property in 1948, subsequently restaked the showings as the Elm group of 9 claims. Work by the company in the 1950's included geological mapping, bulldozer trenching and a small amount of diamond drilling.

The Elm showing is located on Porcupine Creek, just east of the Oxide showing (082FSW022). Workings comprise two adits and a few trenches.

The area is underlain by argillite, slate, quartzite and limestone of the Lower and Middle(?) Ordovician Active Formation which have been intruded by granitic rocks of the Middle to Late Jurassic Nelson Intrusions.

Mineralization consists of small lenses of pyrite, pyrrhotite and sphalerite hosted in steeply dipping limestone. The limestone is around 100 metres thick and bounded to the east and west by black argillites. Some skarnification of the limestones is reported near intrusive contacts. Mineralization is locally associated with fluorite, and scheelite has also been locally noted.
