December 15th, 2005 Torreon, Coahuila Mexico; UC Resources Ltd. (TSXV: UC): Mr. Richard Hamelin is pleased to announce that based on early results from the current exploration program the board of directors of UC Resources have approved expanding the proposed 2005 / 2006 exploration program on its 19,269 hectare (192 sq km’s) historically productive gold and silver Copalquin Project in Northwest Durango, Mexico.

The company has been advised by our geological consultants that a recently completed satellite imaging (ASTER) project has identified multiple high priority targets approximately three kilometers east of the El Cometa – El Refugio target area.   

The objective of the satellite imaging program was to determine if known outcropping mineralized zones, specifically the El Cometa - El Refugio target areas, have a distinctive signature.  The ASTER imagery clearly delineated an extensive, probable kaolinite - alunite alteration zone (clay alteration zone) that coincides with an area of mapped kaolinite alteration situated between the El Cometa and El Refugio prospects.  This style of alteration is typical of the upper levels of an epithermal vein system and results of the program clearly supports the current geological model that predicts that the El Cometa and the El Refugio are part of a more extensive mineralized area.

The anomalous areas identified to the west of the El Cometa – El Refugio area exhibit responses that are very similar to the response associated with the mapped kaolinite alteration zones.   These areas may represent an extension of the epithermal system at Copalquin or they may represent parts of a previously unrecognized epithermal system.  During the next few weeks these target areas will be the focus of detailed mapping, geochemical sampling and if warranted diamond drilling as part of the current exploration program at Copalquin.

Richard Hamelin reports: “Utilizing modern exploration tools like Aster imagery and other geological and drilling technology in Phase two at Copalquin, I believe UC will soon have significantly more information on this 192 sq. km land package. As UC now has a 100% interest at Copalquin and the attractive interest that Mexico, Gold & Silver and in general, the investment interest in the prolific Sierra Madre Occidental Mining Belt we are in a much better position going into 2006. 

Mexico is and remains an extremely attractive region for international investment of developing mining projects.  Copalquin is showing signature quality’s of a typical epithermal deposit and with its significant historical silver and gold production combined with the positive results from Phase 1, our team has great confidence that Phase 2 it will bring to light new targets and data that will prove invaluable to us."
