Capsule Geology

The AGUR-1 showing is a postglacial uranium concentration in soils and in stream sediments. It is located in a marshy area beside a stream approximately 9.0 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 averages 0.0220 per cent uranium over an area measuring 3,000 square metres (Culbert, 1979). The uraniferous layer lies 1.0 metre below the surface and has an average thickness of 2.0 metres (Culbert, 1979). Within that layer a 0.5-metre section grades 0.0558 per cent uranium (Culbert, 1979). The area is also anomalous in molybdenum; a 0.5-metre section grades about 0.03 per cent molybdenum (Culbert, 1988).

Other young uranium occurrences located nearby are AUGER-7 (082ENW070) and AUGER-HILL (082ENW086).
