Capsule Geology

The claim is underlain by rocks of the Lower Jurassic Rossland Group, Elise Formation, which have been altered to a banded hornfels. The magnetite-rich hornfels or magnetite-skarn occurs along the contact between the Rossland Group rocks and the Early Jurassic Rossland monzonite. This intrusive stock consists of a mass of biotite-hornblende-augite monzonite and contains epidote, chlorite, magnetite with pyrite and pyrrhotite.

Mineralization, which occurs along the monzonite contact, is considered part of the south belt vein system and consists of pyrite, pyrrhotite and magnetite in veins and in semi-massive form. In 1967, very minor amounts of galena were observed in association with native bismuth in a pit northeast of the Deer Park mine (082FSW122). The two minerals were intimately intergrown in a specimen that was examined. The intergrowth may have resulted from simultaneous deposition or, since a number of lead-bismuth sulphosalt minerals are known, from a later breakdown of a single parent material (Thorpe, 1967).
