Partial relinquishment report for the period 1 September 2006 to 31 August 2008

Abstract

The exploration programme for EL 25010 proposed in 2007-08 was not conducted due to staff shortage issues. As part of the requirement to undergo a 50% partial relinquishment a brief review of geology and previous work was undertaken. Following is a summary of the review. The area of EL 25010 is at the unconformable junction of the Gardiner sandstone and the Nongra Beds of the Lower Proterozoic in a faulted anticline. At the northern and eastern sides of the tenement the 1:500,000 geological map shows the presence of Antrim basalts covering the Proterozoic rocks. These basalts have a strong regional Th/U profile. Quaternary channels draining the tenements have calcrete development in the north of the tenement. Radiometric signatures over the channelised calcretes are low. There are no known mineral deposits in the tenement. The area suggested for reduction was selected on the criteria that all areas with Antrim basalt at surface were unlikely locations for near surface concentrations of U and significant basemetal (copper). Odd blocks of Proterozoic Gardiner Sandstone on the eastern side of the tenement were added to the selection to make up numbers, these blocks were selected on the basis of the regional U signatures.
