Hi everyone, Candente Resource Corp. and Canaco Resources Inc.: Drilling Intersects Vertical Extensions to Four Historical Gold and Silver Veins at El Oro 10/4/2007 VANCOUVER, BRITISH COLUMBIA, Oct 4, 2007 (Marketwire via COMTEX News Network) -- Candente Resource Corp. (TSX:DNT)(BVL:DNT)(WKN:GW4) (Candente) and Canaco Resources Inc. (TSX VENTURE:CAN) (Canaco) are pleased to announce that eight drill holes have been completed to date and all holes have intersected the targeted down-dip extensions of the El Oro veins. These intersections demonstrate vertical extensions to four of the most prolific veins at El Oro. Samples of core from all veins have been sent for analysis. Results have been received for the three drill holes in the San Rafael Vein, the rest are pending. Three holes were drilled over a 2.8 kilometres (km) strike length on the San Rafael vein; one hole tested the Borda vein; three holes were drilled over a 0.6 km strike length on the Coronas vein; and one hole has been completed along the Verde vein. "We are extremely pleased with the results to date," said Andrew Lee Smith, President of Canaco Resources Inc. "The San Rafael Vein in particular provides an impressive context for this drilling with in excess of 5 Million (M) gold equivalent ounces having been produced from 200 vertical meters (m) of mining operations. Intersecting typical San Rafael vein material in three locations and gold-silver mineralization at a depth of 70 m below the historic workings is undoubtedly significant. The presence of vein continuity without pervasive high grades is very typical of this prolific vein." VSR-07-02 was previously reported to have intersected 2.90 m of 7.79 grams of gold per tonne (g/t Au) & 8.13 grams of silver per tonne (g/t Ag), approximately 20 m below the deepest known level of previous mining on the San Rafael vein, however, both the grade and the vein depth extension have increased with a check assay including a more accurate screen fire assay and a re-interpretation of structures. The new results give 7.2 m (5.11 m true width) of 4.05 g/t gold & 4.9 g/t silver including 2.90 m (2.06 m true width) of 9.27 g/t gold & 8.13 g/t silver 70 m below the deepest known historical workings. As previously reported, drill hole VSR-07-02 also intersected high grade silver mineralization of 1330 g/t over 3.05 m (within a zone containing 726.38 g/t over 5.60 m) which could be a new vein discovery (Previously reported in NR217, Tue. Jul 3, 2007). The 4,000 m Phase One drilling program is nearly completed and will be limited to nine holes instead of the 13 originally planned due to the fact that some holes were drilled deeper than originally planned.

Geological mapping and data compilation in the Oriente area has identified 6 drill targets to date. It is mostly covered by younger Tertiary Volcanic rocks masking favourable host rocks and potential veins. Seven exposures of the favourable host rocks have been found within these younger volcanics and five of these have alteration and quartz-calcite veining and stockwork typical of the El Oro gold-silver veins. Regional soil geochemical sampling in Zona Oriente identified gold anomalies in soils and silts (19 to 44 ppb and 34 to 90 ppb respectively) located on strike with a previously mapped Andrea vein. Additional soil sampling has been carried out in this area and it will be followed up by trenching. Sample results are pending. A NSAMT geophysical survey has also been carried out over the Oriente area to assist in the identification of potential new veins. The NSAMT final report and recommendations will be combined with geochemical and geological data to identify additional drill targets. Major Drilling de Mexico, S.A. de C.V. is under contract to carry out the drilling program. Drill core is cut on site using a rock saw. Half of the core samples are submitted to the assay lab for analysis while the remainder are stored in core boxes for future reference. A QA/QC program involving the use of 3 standard samples and a blank has been incorporated into the sampling regime for the project. Samples are sent to ALS-Chemex Laboratories, an internationally recognized assay service provider. Sample preparation is done in Guadalajara, Mexico and analysis using ME-ICP41m, AA-AA24 in North Vancouver, Canada. Additional information on the companies and the El Oro property is available at www.candente.com and www.canaco.ca. Candente and Canaco have chosen to jointly explore at El Oro to take advantage of the companies combined abilities and successful track records in exploration, discovery, project development and mining operations. The companies have formed a Mexican subsidiary named Minera CCM SA de CV to operate this joint venture. Piotr Lutynski, P.Eng. Consultant, Michael J.
