EL 30157 Partial relinquishment report 9 June 2009 to 8 June 2014

Abstract

Exploration work carried out during the reporting period tested models for base metals and uranium mineralisation at the Yiyintyi West (Y1) and Yiyintyi East (Y2) Prospects. RC drilling at Yiyintyi West Prospect between 16th and 27th October 2010 was completed by McKay Drilling for 8 drillholes and a total 1,193.0m. A fixed wing airborne Magnetic-Radiometric survey by Fugro Airborne Surveys was flown early October 2011 over both prospects along northwest and northeast oriented traverses at 50 metre line spacing and 40 metre nominal height clearance for a total of 1,163.13 line km. Reconnaissance mapping was carried out at 1:20,000 on an orthophoto of Yiyintyi Sandstone along the north-eastern Yiyintyi Range at Yiyintyi East (Y2) concurrently with a ground radiometric survey on four east-west lines and three RC drill holes 11BLRC0174-176 for a total 442.0m to test an airborne radiometric anomaly. This was followed by a helicopter-borne transient electromagnetic - magnetic (HELITEM) survey between 31st October and 2nd November 2011 which covered both prospects. The survey parameters were along identical northwest and northeast oriented traverses at 150m line spacing for a total 327 line. The transmitter loop was slung below the helicopter at 35m elevation with the receiver platform at 63m elevation. As no encouraging results were returned from the drilling, and due to the Limmen National Park being formalised in 2012, the least prospective blocks within the National Park were chosen to be relinquished.
