China Yunnan Copper Australia hits significant rare earths in Goldsearch JV
Thursday, February 24, 2011 by John Phillips

China Yunnan Copper Australia (ASX: CYU) and Goldsearch (ASX: GSE) have hit some significant copper-cobalt and rare earth element-uranium mineralisation at the Elaine Dorothy, Mary Kathleen joint venture in Queensland.

Highlights include:
- 25 metres at 2043 parts per million (ppm) total rare earth oxides (TREO), 0.07 kilograms per tonne U3O8 from 69 metres; and
- 13 metres at 2550ppm TREO, 0.09kg/t U3O8 from 149 metres, including 7 metres at 3300ppm TREO, 0.13kg/t U3O8.

Adding to this success, is a new the discovery of a new zone of copper-cobalt sulphide mineralisation, including:
- 49 metres at 0.44% copper, 283ppm cobalt, from 25 metres, including 24 metres at 0.63% copper and 301ppm cobalt.
The TREO and uranium mineralisation find is perfectly positioned, just 200 metres along strike from the Elaine Dorothy JORC Inferred Resource of; 83,000t at 0.28kg/t U3O8 and 3200ppm TREO, undertaken by Hellman and Schofield Pty Ltd.

China Yunnan said the newly discovered uranium-rare earth mineralisation is dominated by cerium, and is generally fracture related with narrow breccias to 5 centimetres developed, within the garnetite-dipside skarn.
The company added that the mineralisation may be related to the presence of black laths, tentatively identified as allanite and is associated with carbonate-magnetite-tremolite alteration and fracture fill.
This style of mineralisation is thought to be similar to that of the Mary Kathleen deposit.

Infill drilling will kickoff soon in the 200 metre zone between the new discovery and the Elaine Dorothy resource, to explore for the continuation of the uranium - rare earth mineralisation.

Scout drilling is also planned at the Elaine 2 and Elaine 3 prospects.
