Oremex Reports Equivalent Silver Resource of 40.3 Million Ounces

AN INDEPENDENT RESOURCE STUDY has concluded that an equivalent silver resource of 40.3 million ounces is contained in a total of 10,190,000 tonnes, grading a silver equivalent of 123.47 g/t (3.97ounces) on OREMEX'S TEJAMEN SILVER PROPERTY, STATE OF DURANGO, MEXICO.

Vancouver, Canada, March 8, 2005: Oremex Resources Inc. has received the results of an independent Resource Evaluation Report (the "Report") on its Tejamen Silver Property in compliance with National Instrument 43-101. The Tejamen Silver Property, consisting of 21 claims covering about 1,672 hectares is situated in the municipality of Nuevo Ideal, State of Durango, Mexico. (www.oremex.com).

The Report, written by Norman L. Tribe, P.Eng., of N. Tribe and Associates Ltd., covers two areas of mineralization, the Cerro Prieto and the Los Mantos (previously El Manto). It states "Total tonnage for the Tejamen deposits is 10,190,000 tonnes at a grade of 119 grams per tonne of silver (3.82 ounces/tonne) with 0.07 grams per tonne of gold. (0.0024 ounces/tonne). Contained ounces for the deposits are calculated at this time to be 38,915,000 ounces of silver and 24,127 ounces of gold."

This is equivalent to a resource of 40,320,000 ounces of silver at a grade of 123.47 grams/tonne or 3.97 ounces/tonne. (A 60:1 silver/gold ratio was used for the silver equivalent). A cutoff grade of $6.00US/tonne combined silver and gold was used to arrive at an estimate of the resource in these two deposits. The silver price used was $6.80US/ounce and the gold price used was $425US/ounce. No recovery factor is applied to these numbers as insufficient information is available on recovery parameters at this time. Metallurgical variables will be determined in the next phase when metallurgical testing is done.

The resource estimate contained in the Tribe report derives from the study of a 166 reverse circulation drill program, which commenced in December 2003 through December 15, 2004, totaling 26,500 meters of drilling on sections 50 meters apart with drill holes 30 meters apart along sections on the Cerro Prieto and Los Mantos zones. The holes were drilled at 60 degrees to the south, to a nominal drill depth of 200 meters, on the Cerro Prieto; and, vertically on the Los Mantos to a nominal depth of 150 meters.

Tribe suggests that there is a system of flat faulting, parallel to the bedding and dipping 15 degrees to 25 degrees S., present in the host rocks of both the Cerro Prieto and Los Mantos. Much of the mineralization is associated with these flat faults. The feeder vein at Cerro Prieto is strong and crops out into the hill that spawned the name. Most of the values in the Cerro Prieto deposit are close to this feeder vein structure. This feeder shear vein forms a distinctive sigmoidal loop. Other loop structures appear as Jeronimo and Carnival feeders between the Los Mantos and the Cerro Prieto Zones.

The Los Mantos area has similar mineralization and structure as the Cerro Prieto. There is a sigmoidal loop passing through the main part of the deposit marked by the Guanajuato and Morelos feeder veins and at least five low angle mineralized thrust faults which host much of the mineralization. The solutions traveling upward along the feeder encountered several of these N40°E flat, 20 to 40°E structures and mineralization has spread laterally parallel to the faulting and the bedding in the host, Lower Volcanic Complex .

Mineralization consists of galena, sphalerite, pyrite, and minor chalcopyrite, tetrahedrite and argentite in a gangue of quartz and clay minerals. Native silver and free gold are reported to occur in the strongly oxidized areas. This flat faulting may be more pervasive than previously thought, with a number of imbricated structures providing favorable environment at several layers in the volcanic pile, in the Cerro Prieto deposit, the Los Mantos deposit and in the surrounding area."

The proximity of an open pit mining operation, to the village of Tejamen is being addressed and may at some point require the relocation of the village residents. Informal meetings with the senior village representatives and the Company are being held on a regular basis in order to maintain a dialogue, with positive results.

The Report summarizes that "the mineralization is not completely defined and that more potential exists between the two zones, at depth, along strike in both directions and possibly on other structures to the southeast." As well,"the mineralization is related to steep feeder veins with mineralization spreading out horizontally along shallow thrust faults, or 'mantos'." Mr. Tribe states that there are numerous 'mantos', therefore the change of the name of the El Manto zone (singular) to the Los Mantos area (plural).

The Report concluded that further work is justified and recommends a program of 22,090 meters of drilling in 135 drill holes; metallurgical work to ascertain the recovery parameters; fill-in drilling and exploration drilling to define the limits of the mineralization.

Oremex is now proceeding with the recommended drill program on the Cerro Prieto and Los Mantos zones, to further define the parameters of the known resource.

A copy of the "Report" will be filed on Sedar in the near future.
