The Marble copper occurrence is located west of Garnet Lake, approximately 13 kilometres northwest of Summerland.
The area is underlain by a roof pendant of Upper Triassic Nicola volcanic sediments enveloped by middle Jurassic intrusions of the Okanagan Batholith and Tertiary syenitic plugs. The pendant is cut by major north-, north east- and east- trending faults and by numerous syenite, diorite, pegmatite and granodiorite dikes and quartz veins.
Locally, contact metamorphic rocks consisting of biotite schists, amphibolites, marble and limy argillites have been locally altered to siliceous garnet skarn.
Mineralization occurs as pyrite, chalcopyrite and molybdenite hosted in quartz veins up to 60 centimetres thick. Pieces of massive galena and sphalerite float are also noted.
Between 1986 and 1989, various programs of geological mapping, geochemical sampling and minor geophysics were completed on the Marble claims. Several old prospecting pits of unknown age were noted. In 1989, sampling of mineralized material returned up to 8100 parts per million copper, 10.0 parts per million silver and 114 parts per billion gold (Property File: Minnova Inc. (1989-09-20)).
