The CONTACT POOL showing is a postglacial uranium concentration in a pond and in surrounding marsh soils. It is located approximately 3 kilometres northwest of Summerland.

This is one of many uranium occurrences discovered by D.G. Leighton & Associates Ltd. in the late 1970s. Work prior to the uranium moratorium in 1980 consisted of auger sampling. The area is underlain by Eocene trachyte, andesite and pyroclastic rocks of the Marron Formation, Penticton Group which unconformably overlie granodiorite of the Jurassic Okanagan Intrusions.

The occurrence is recent, having formed from the interaction between uranium-rich groundwater and unconsolidated material containing organics or clay. This process is believed to still be taking place. The source of the uranium is thought to be the surrounding igneous and volcanic rocks, where groundwaters rich in carbonate and alkali ions have leached labile uranium from fresh rock exposed after glaciation.

Uranium enrichment occurs over an area measuring 3,800 square metres (Culbert, 1979). An auger hole intersected a 5.5-metre thick layer averaging 0.0302 per cent uranium with a 0.5-metre section averaging 0.0517 per cent uranium (Culbert, 1979). Molybdenum averages up to 0.04 per cent over 0.5 metre (Culbert, 1988). The uraniferous layer lies 1.0 metre below the surface (Culbert, 1979).
