Orex Minerals' Work Program Underway on Santa Cruz Property

Vancouver, B.C. - Orex Minerals Inc. (formerly Orex Ventures Inc.) - REX: TSX-V is pleased to announce that work is underway on the Santa Cruz Project in Durango State, Mexico in joint venture with Silverex S.A. de C.V.

Located in the Sierra Madre Occidental Mountains, Otaez Municipality, midway between Tayoltita (San Dimas) and Topia mining camps, the Santa Cruz Property is in one of the World's most prolific mineral belts. Santa Cruz is an epithermal gold-silver camp divided into three structural districts. The property hosts three main gold-silver bearing districts, the Eastern, Central and Western, as well as the previously operating Santa Cruz Mine.

Road access to the Orozco area of the Eastern District has now been completed. Construction of new roads to access the Zambraneña and Jesus Maria areas of the Western District is proceeding well following the rainy season.

Additional reconnaissance rock sampling analysed in October from the Western District is in agreement with the March 2007 sampling and has confirmed the high gold and silver prospectivity of this part of the Santa Cruz Camp, in particular the Zambraneña area.

Gary Cope, President of Orex, adds, "We are extremely pleased with the initial sampling results from the Santa Cruz Project. Although we were aware that historical records show that multiple areas of the project produced very high grades of Silver and Gold, it is very gratifying when our own current sampling has produced very good results. We anticipate that the mill upgrades will be completed in the first quarter of 2008 and that test milling from the 90 ton/day plant will begin shortly thereafter.

Once the Work Program of upgrading and extending current roads has been completed, a full scale exploration program will begin immediately. We are currently evaluating numerous drilling options and anticipate signing a contract shortly. We believe that the Santa Cruz project will be a very nice combination of production and exploration.

Our joint venture partner Silverex will operate the mill and oversee test milling from both the mill and the highly lucrative tennantite operation which is not milled but hand-cobbed and sold directly to Chinese buyers.

All proceeds from test milling on the project will be split 50/50 between the two companies. All exploration will be overseen by Orex Minerals Inc."

The Western District, which will be a major target area for Orex, has vein structures traced for over 2.5 km strike length. It consists of from northwest to southeast the Carmen, Zambraneña, Christian and Jesus Maria showings.
