Ascendant Copper Announces Exploration Results From the Gur Gur Anomaly Drilling Program, Chaucha Copper Project, Ecuador
DENVER, COLORADO--(CCNMatthews - June 6, 2007) - Ascendant Copper Corporation (the "Company"), (TSX:ACX)(TSX:ACX.WT)(BERLIN:A0HMLE)(FRANKFURT:A5C)(WKN:A0HMLE), is pleased to announce drilling results from an ongoing core drilling program at the Gur Gur target area located within the Company's Chaucha copper-molybdenum property, 75 kilometers southeast of Guayaquil, Ecuador. The nine-hole, 1,341 meter program intersected large widths of high-grade copper-molybdenum mineralization within envelopes of lower grade mineralization (see attached plan view, layout map for drillhole locations. To view, please click the following link: http://www.ccnmatthews.com/docs/acx0606.pdf). To date, five of the nine holes have been analyzed. These holes have encountered a supergene enrichment zone about 40 meters thick with copper values in many areas of this enrichment zone exceeding 0.50%. In addition the drilling and surface geology has begun to define what appears to be a porphyry system underlying the Gur Gur mineralized sector of the Chaucha concession.

The holes analyzed to date were drilled into a previously inferred copper-molybdenum resource as estimated by Billiton in 1998 (Billiton's resource estimate was prepared prior to the creation of the CIM Standards on Mineral Resources and Reserves Definitions and Guidelines and is not compliant with National Instrument 43-101, Standards of Disclosure for Mineral Projects). Existing logs report that Billiton drilled five holes totaling 931 meters with one of the Billiton drillholes, Ch-03, intercepting 105 meters that graded 0.63% copper and 0.02% molybdenum, but this has not been independently confirmed by the Company by reassaying.

Ascendant's drillhole GG-02 intercepted 70 meters of 0.39% copper, which included 36 meters that graded 0.54% copper, GG-03 included 172 meters of 0.40% copper and drillhole GG05 encountered 140 meters grading 0.35% copper, which included 60 meters grading 0.52% copper. Assay results from the five holes are set out in the table below. True thickness is estimated to be equal to drilled thickness as the mineralized zone encountered is determined to be flat-lying.
