Ascendant Copper Announces Promising Surface Sampling Results from its Telimbela Copper Property

VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - March 22, 2007) - Ascendant Copper Corporation (the "Company") (TSX:ACX)(TSX:ACX.WT)(FRANKFURT:A5C)(BERLIN:A0HMLE) announces that recent mapping and surface sampling on its Telimbela copper property, located about 35 miles northeast of Guayaquil, Ecuador have outlined a previously unrecognized zone of significant copper mineralization covering an area of about 28 hectares (70 acres). Fourteen chiseled rock chip samples over a length of approximately 40 meters encountered values as high as 1.93% copper with an arithmetic mean of 0.80% copper. Chip samples were typically two meters in length by one meter in height and comprised of 3.0 to 4.8 kilograms in weight of material collected uniformly over the length of the sample area. Additional ridge line soil sampling adjacent to the discovery zone continued to give encouraging assay results yielding copper grades as high as 1.07% copper. The discovery zone is considered to be open in all directions.

Currently two teams of geologists are at work within the Telimbela concession concentrating on this new discovery zone as well as the previously explored Central zone which was drilled by a Japanese consortium in the 1970s. A program of mapping, rock and soil sampling and reconnaissance geology will determine favorable sites for drilling expected to commence in late spring 2007.

The Telimbela property lies in the same belt of rocks which hosts such copper resources as the Company's Chaucha and Junin projects. The rocks are diorites and tonalities with roof pendants of earlier andesites and are copper prospects with iron-oxide, copper-gold affinities. Mineralization is dominantly extremely fine-grained chalcopyrite. The newly identified discovery zone is elongated in a north-south direction consistent with the structural controls in the area.

John R. King, the Company's resident exploration and geological expert as well as a Qualified Person as defined by National Instrument 43-101, Standards of Disclosure for Mineral Projects ("NI43-101"), has reviewed the above statements and assay results. Mr. King confirms that quality controls and correct assay procedures were followed by the Company and these geologic observations of the samples are correct.

Assaying of the samples was conducted by ALS Chemex Laboratories, an ISO certified laboratory in Santiago, Chile.

Ascendant's principal business is the exploration for copper in Ecuador. The Company has two primary properties; Chaucha and Junin. The Chaucha property is partnered with Antofagasta plc (LSE:ANTO) for exploration and advancement. The Company has also acquired the rights to an extensive exploration data base developed for Ecuador by Rio Tinto Mining and Exploration Limited (LSE:RIO) and has an option to purchase 100% of the Telimbela copper/molybdenum property.
