The property lies within the Shuswap Metamorphic Complex along the northwestern margin of the Frenchman Cap Dome. The core of the dome is composed of a mixed paragneiss and orthogneiss succession of probable Aphebian age. The dome is mantled by unconformably overlying metasedimentary rocks consisting of quartzites, calcare- ous schists, marbles and pelitic schists.

The mineralized zone occurs on the lower (eastern) limb of a northeast trending part of the Grace Mountain syncline - a tight isoclinal fold. Chalcopyrite and coarse-grained galena occur in a 10 centimetre quartz layer within marble for a 30 metre length. A galena-rich section, 2 metres long assayed 16.1 per cent lead and 0.8 per cent zinc (Bulletin 80). The carbonate unit is bounded by grey banded garnet-biotite gneiss and muscovite biotite gneiss.

Several small occurrences occur over an 800 metre strike length and a minor occurrence lies 1700 metres to the west.

Work History

In 1977, J.R. Woodcock completed a program of prospecting, geological mapping and geochemical (rock, soil and silt) sampling on the area as the Seymour 1-4 claims.

In 2011, TriGold Resources Inc. completed a program geochemical (rock and soil) sampling and an airborne geophysical survey on the area as the Copper King-Cotton Belt property.
