Kirrin’s airborne magnetic-EM survey at Key Lake SW utilized Fugro’s fixed-wing Tempest(r) Digital Time Domain Electromagnetic (DTDEM) system which provides maximum quantitative discrimination of relatively near surface (upper 200mt to 300mt) conductivity variations.
Kirrin has appointed Condor Consulting of Lakewood, Colorado, (Condor) to undertake the processing and analysis of the airborne EM and magnetic data acquired by Kirrin. Condor anticipates submitting its report by July.
On January 10, 2010, Delta and Denison reported that high-grade uranium mineralization continues to be encountered on the Phoenix discovery on the Wheeler River Property located in the Athabasca Basin of northern Saskatchewan.
They also said that the results of the fall 2009 drilling program have confirmed that the Phoenix discovery has the potential to host an economically significant, high-grade uranium deposit.
Although the Key Lake SW property is believed to be somewhat southwest of the margin of the current Athabasca Basin, there is evidence (regolith encountered in some old drill holes) that indicates the Athabasca Supergroup-Wollaston Group basement unconformity was not far above the present ground surface within the property.
Discovery of several ‘Ingress style’ uranium deposits, such as Phoenix (up to 117mt below unconformity), Millennium (up to 100mt below unconformity), Eagle Point (up to 450mt below the unconformity) and some other deposits within the Athabasca Basin, indicate that important uranium deposits can occur from several tens of metres up to a few hundred metres below the unconformity.
Hence, there is potential for important basement-hosted uranium deposits to exist within the Key Lake SW property. Regional aeromagnetic data show the Phoenix discovery is associated with a fault which cross-cuts the P2 Rift Fault.
