Capsule Geology

The AGUR-HILL showing is a postglacial uranium concentration in lake-bottom sediments of several ponds. It is located approximately 10 kilometres southwest of Summerland.

This is one of many young 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 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 rocks, where groundwaters rich in carbonate and alkali ions have leached labile uranium from fresh rock exposed after glaciation.

Uranium enrichment occurs in lake-bottom sediments over an area measuring 10,000 square metres. An auger hole intersected a 1.0- metre thick layer averaging 0.0087 per cent uranium with a 0.5-metre section averaging 0.0114 per cent uranium. The uraniferous layer lies 2.0 metres below the surface (Culbert, 1979).

Other young uranium occurrences located nearby are AGUR-1 (082ENW085) and AGUR-7 (082ENW070).
