The Silver Bell occurrence lies at about 1952 metres elevation along a northwest trending ridge formed along the contact of Lower to Middle Ordovician Active Formation limestones and the Hidden Creek granodiorite stock of the Middle to Late Jurassic Nelson Intrusions. Along the contact, grey crystalline limestone is locally altered to coarse calcite and actinolite and in places to garnet, actinolite and other lime silicates typical of skarn zones. The limestones have a general northeast trend with steep dips while the intrusive contact appears to dip east.
Mineralization consists of minor pyrite and barite within altered limestones about 1 metre from the granodiorite contact. In addition three zones of brecciated limestone, 1.2, 0.76, and 2.7 metres wide respectively, contain small pockets of dark brown sphalerite.
