Mary Kathleen Project first-pass drilling results


Encouraging assay results have been received for first-pass, reverse circulation drilling of two target areas completed at the Mary Kathleen Project in late December 2006.

The Mary Kathleen Project is a joint venture between Goldsearch Ltd and Central West Gold NL. Goldsearch is currently earning a 75% interest in the project.

A total of five close spaced holes were drilled at the Elaine Dorothy target located 6km south and along strike from the former Mary Kathleen Uranium Mine. Two holes were drilled at the MacGregor target located 20km south-west from the Mary Kathleen Uranium Mine.

At Elaine Dorothy, the close-spaced drilling was designed to test surface indications of Mary Kathleen-style uranium mineralisation at a depth of between 50m and 100m below surface.

The drilling intercepted two individual zones of uranium and rare earth element (cerium (Ce) and lanthanum (La)) mineralisation. The mineralisation is hosted by the Corella Formation, an altered meta-carbonate sequence with minor metamorphosed mafic volcanic rocks.

The mineralisation style and host sequence is consistent with the nearby Mary Kathleen Uranium Mine and, as at Mary Kathleen, the higher grade mineralisation appears to be associated with the presence of the mafic volcanic rocks within the sequence.

Of the five holes drilled at Elaine Dorothy only one hole, MKRC04 appears to have intercepted the mafic volcanic rocks down hole.

Additional drilling will be undertaken to further evaluate the target once surface exploration is completed and relevant approvals can be put in place. Additional assaying is also required to better determine total rare earth element concentrations.

Based on the positive results from the first-pass drilling at Elaine Dorothy, surface sampling will also commence at the Elaine 2 and Elaine 3 uranium prospects with the aim of defining drilling targets.

At the MacGregor target two wide-spaced holes were drilled to test a broad 1.8km long by 300m wide, coherent scintillometer anomaly associated with a thick carbonaceous shale unit of the White Blow Formation.

The very wide zones of low grade uranium mineralisation intercepted by the first-pass drilling at MacGregor is encouraging and suggests the area may represent a potential stratabound hydrothermal alteration system.

An apparent zoning towards higher uranium values at the southern end of the target has also been recognised along with minor occurrences of copper mineralisation identified during surface sampling at the southern end of the target which is yet to be drill tested.

Based on the encouraging results from Elaine Dorothy and MacGregor first-pass exploration will commence at a number of other regional targets over the coming months.
