Air core drilling has started at Epsilon Energy’s Lake Dundas Uranium Project in Western Australia.

Located south of Norseman in the Eucla Basin, the project covers 64sqkm and is considered prospective for sandstone-hosted uranium deposits. Previous work in the 1950s confirmed highly anomalous values of uranium in Tertiary sediments immediately to the north of the project, however no modern exploration methods have been applied since.

A Tertiary paleochannel is interpreted to pass through the Lake Dundas project. This interpretation is constrained by considerable exploration drilling, mostly outside the tenement, and analysis of remote sensing data. An extensive hinterland provides access to a large volume of leachable ‘hot’ granites and oxidized sandy units in the paleochannel are potential aquifers for transport of uranium.

In the project area there occurs a confluence of palaedrainages and a zone of restricted flow, both of which are favourable characteristics for the creation of uranium mineralization. The geological environment is also considered favourable for supergene enrichment of uranium mineralization.

The aim of the drilling programme is to further define the geometry of the paleochannel, the thickness and stratigraphy of the channel fill to identify potential aquifers and trap sites, and to locate areas of uranium mineralization.

Interim holes will be encased with PVC piping for downhole gamma logging at a later date. An Exploranium GR320C portable spectrometer will also be used to measure U3O8 readings from chip samples, which will assist the identification of specific samples to be assayed for uranium.
