A drilling program consisting of six RC holes totalling 1,336 metres was completed at the Cargo Porphyry Cu-Au prospect in New South Wales, Australia during Q2/07. The holes were drilled on two fences spaced 200 metres apart with a between-hole distance of approximately 100 metres. Holes dip at -60 degrees to the north-northeast and range from 135 to 250 metres in length. Holes tested targets based on structural and alteration mapping undertaken in December, 2006. The program tested the continuity of intensely-altered, steeply-dipping copper and gold- bearing hydrothermal breccia bodies. As well, it obtained geological information from a 350 by 300 metre untested area located between the main area of outcropping alteration and the Essex gold prospect. Assay results for the drill holes will be released once they have passed QA/QC. This will be on completion of check analyses, which are now in progress.

A helicopter GEOTEM EM and magnetic survey has been completed by Fugro Airborne Surveys Corp. ("Fugro") over the Company's Point Leamington Au-Zn-Cu-Ag massive sulphide prospect in Newfoundland, Canada. A total of 2,532.6 line kilometres was flown at a 200 metre line spacing. In response to preliminary results, the Company has staked an additional 58 claims to cover potential targets in areas of favourable stratigraphy. The new claims bring the total property area to over 29,000 hectares. Results and a final report are expected from Fugro in June.

The Company announces that Dr. Richard Henley has resigned from the Board of Directors of TLC Ventures Corp. The Company would like to thank Dr. Henley for his significant contributions and wishes him well in his future endeavours.
