| July 27, 2005 Initial Drill Results from Lucky Joe Project | |
| Vancouver, BC, July 27, 2005 - Copper Ridge Explorations Inc. ("Copper Ridge" or "the Company") is pleased to announce the results of the first two of five drill holes completed on the Lucky Joe copper-gold project near Dawson City, Yukon. The drilling tested an approximately 3.5 km length of the main Papa Bear copper-gold soil anomaly, with dimensions of over 11 km long by 2 to 2.5 km in width, and related IP chargeability anomalies. Copper Ridge is operator of the program while Kennecott Canada Exploration Inc. ("Kennecott"), a Canadian subsidiary of Rio Tinto plc is financing the program. The drilling confirmed the presence of porphyry style copper mineralization over a broad area. Drill hole LJ05-01 targeted an area of anomalous copper-gold soil geochemistry overlying favourable metamorphosed intrusive and metaclastic host rocks. The hole remained in a fault zone for much of its length and was terminated at a depth of 148.1 m due to bad ground conditions. The hole contained extensive disseminated pyrite as well as minor disseminated chalcopyrite through much of its length. The highest grade intervals included 24.1 m grading 0.06% copper beginning at 18.6 m and 33.5 m grading 0.071% copper beginning at 77.9 m. Drill hole LJ05-02, 600 m southeast of hole 1, targeted anomalous copper soil geochemistry overlying a large IP chargeability anomaly. The hole encountered disseminated pyrite mineralization throughout, with increasing disseminated chalcopyrite mineralization and strong potassic alteration with depth. The best results included 22.7 m averaging 0.217% copper and 88.5 ppb gold, starting at 255.4 m, within a 94.7 m interval of 0.13% copper and 52.4 ppb gold, to the end of the hole at 352.1 m. The drilling appears to confirm studies to date by Kennecott and Copper Ridge geologists that suggest that Lucky Joe is a metamorphosed porphyry copper-gold deposit. The strongest copper mineralization correlates with potassic (biotite) and magnetite-silica alteration with 3% to 5% disseminated pyrite. Overlying this is a shell with lower copper values and 5% to 10% disseminated pyrite. There appears to have been some disruption of the classic porphyry deposit morphology by subsequent metamorphism and deformation. Three additional holes have been completed on the property, along a 3.5 km strike length, and will be reported as soon as assay results have been received. This press release has been reviewed and approved for release by Gerald G. Carlson, Ph.D., P.Eng., the Company's President & CEO and designated Qualified Person. Please see the Company's web site -- www.copper-ridge.com -- for detailed project information. Drilling at the Company's Yukon Olympic Property has now been completed. Four holes were drilled for a total of 470 m. Results will be released as soon as they are received. Copper Ridge has been highly successful in securing eleven large-scale, early-stage gold and copper properties in the Yukon, Alaska, B.C. and Mexico, three of which are under option to mineral exploration companies. This strategy enables Copper Ridge to minimize risk and financial exposure while maximizing the chances for exploration success and freeing up resources to seek out prime new acquisitions. Copper Ridge is well financed and anticipates an active field season in 2005. For further information contact: Gerald G. Carlson, President & CEO Copper Ridge Explorations Inc.
