Mineralization is a vein deposit in a crackled zone at a dike margin, with the ore zone hosted in arkose. The vein material occurs mostly in dike rock. Abundant diversely oriented veins to 10-12 cm wide intersect but coalesce at intersections - do not cross-cut. There is no through-going structure. Ore control was the contact of the Silver Lily Dike and surrounding argillite. An associated rock unit is plutonic igneous rock.
Workings include a large pit and smaller pit 20 meters downhill to the E.
