Copper Ridge is exploring Castle Rock's Quitovac property in northern Sonora and in the past has hooked up with Luismin S.A. in a strategic alliance.

Quitovac, Sonora. The Property consists of 13 contiguous mining titles covering 2,484 hectares. Copper Ridge can earn a 55% interest in the Quitovac property from CastleRock Resources Inc. by spending US$1.5 million, making payments of US$375,000 and issuing one million shares over five years. Copper Ridge can earn an additional 20%, for a total 75% interest, by producing a feasibility study. CastleRock retains a 1% NSR.  Quitovac is a gold deposit located in Sonora State in northern Mexico, near the Arizona border. The deposit has many similarities to the nearby La Choya gold mine that profitably produced approximately 400,000 ounces of gold for Hecla Mining during the period 1994 to 1999. It also has similarities to a number of other nearby structurally controlled gold deposits such as La Herradura (Newmont and Peñoles - 145,000 ounces of gold produced in 2002) and El Chanate deposits in Sonora as well as the Mesquite, Picacho and American Girl deposits in the adjacent United States. Presently, the Quitovac deposit remains open along strike in both directions and down dip. In April through June of 2004, Copper Ridge completed a 1,154 m drill program of 13 holes, most of which were drilled parallel to the existing reverse circulation drill holes. Because of broken ground conditions, core recovery was very poor and gold values were low. The Company believes that most of the gold was lost in the return water during the drilling process and that the core drilling results are not representative of the amount of gold in the rock. The Company is evaluating these results prior to determining its future plans for the Quitovac property.

Copper Ridge Explorations reached an agreement with Luismin S.A., Mexico's second largest gold producer and third largest silver producer, regarding the Gavilanes and El Salitre projects in Durango State. The deal allows Copper Ridge to earn a 55% interest in Gavilanes by spending US $1.0 million on exploration over three years and by issuing 150,000 shares, though Luismin can then earn back to a 51% interest by spending the next US $500,000 on exploration and paying Copper Ridge US $100,000. Copper Ridge can also earn a 60% interest in El Salitre by spending US $750,000 over four years and issuing 100,000 shares. Luismin can also earn back to a 51% interest by spending the next US $600,000 on exploration and paying US $60,000. (May 25/00)

Signed a strategic alliance for exploration projects in Mexico with Minas Luismin, S. A. de C. V. (Luismin). Luismin is Mexico's second largest gold producer and third largest silver producer with three active mines and over 45 exploration projects throughout Mexico. Luismin's annual production is 190,000 ounces gold equivalent at an average cash cost of US$190 per ounce. San Dimas is Luismin's main operation where ore is produced underground from high grade veins with an average historical grade of 0.48 oz./ton gold and 34 oz/ton silver. San Dimas has produced 9 million ounces of gold and 654 million ounces of silver. Copper Ridge has reviewed Luismin's exploration portfolio and has selected 11 projects that will form the basis for the strategic alliance. The Company is now in the process of a comprehensive due diligence analysis of these projects to prioritize them for possible future exploration agreements. The selected projects are mainly epithermal vein systems with the potential for discovery of bonanza-grade gold-silver ore shoots. The strategic alliance will be of significant benefit to both parties. For Copper Ridge, it provides a portfolio of high-quality exploration projects on which to focus its efforts, as well as a strong Mexican partner. Copper Ridge will apply state-of-the-art exploration techniques including multi-element geochemical analysis, mineralogical and clay alteration studies and fluid inclusion studies combined with detailed geological mapping and structural synthesis to define the highest priority drill targets. It is the Company's expectation that it will option and explore between one and three Mexican projects this year. Luismin will provide technical and logistical assistance to Copper Ridge for its Mexican operations. Eduardo Luna, President of Luismin, stated "This alliance will assist Luismin in the development of some of the projects of the vast land portfolio that our company owns. It is important to join forces with a successful exploration entity such as Copper Ridge." Gerald Carlson, President of Copper Ridge, stated, "We are pleased to have this partnership with one of Mexico's most highly regarded mining companies.

Oaxaca State Projects. Claimed the San Carlos and La Gitana concessions as protected ground around property optioned from Luismin and Almaden Resources. Almaden has acquired an option on La Gitana which hosts an epithermal vein system with the potential to develop a significant tonnage of bonanza-grade gold-silver mineralization. The property has seen very little exploration to date and lies at an elevation of 1200 to 1500m, 11 km from a paved highway. Early in 2001 it was optioned to Copper Ridge Exploration who can earn a 60% interest by spending U.S. $500,000 with the issuance of 200,000 shares to your company and by making all payments to the underlying vendors. Copper Ridge can then earn an 85% interest by spending an additional $500,000 over two years. Recent sampling by a major mining company reported 2,560 grams per tonne (gpt) silver (82.3 oz/ton) and 21.4 gold (0.69oz/ton) over 2 m, within a 21 m sample across 3.5 m and 983 gpt silver and 0.45 gold. Other parts of the vein are largely covered with overburden. A second area of mineralization associated with opaline silicification has been identified. Sampling by the same major company in this area has returned broad zones of low grade gold and silver values (38 gpt silver and 0.5 gpt gold over 168m; 30 gpt silver and 0.65 gpt gold over 153.5 m ), indicating that this area may be the upper portion of a second epithermal vein system.
