News Releases

Vancouver, BC - Orex Minerals Inc. - (TSX-V: REX) ("Orex"), is pleased to announce that the Phase-II diamond drilling program continues to intercept silver mineralization on the Sandra Escobar Project in Durango, Mexico. Assays for eight more drill holes are now available. These include holes SA-16-023 to SA-16-030 in the southeastern region of the project. The Sandra Escobar Project is being advanced by Orex under an option agreement with Canasil Resources Inc. - (TSX.V: CLZ) ("Canasil").

Highlight for this batch of holes is SA-16-023, which yielded 46 metres core length (40.5 m true thickness) grading 218 g/t silver, starting 25 metres vertically below surface. Within this is a sub-interval of 4 metres (3.5 m true thickness) grading 820 g/t silver.

Six of the eight holes, SA-16-023 to 027 and SA-16-030, are in the Main Zone. Hole SA-16-030 seems to mark the eastern boundary of the Main Zone.

In addition, prospecting has identified the geological horizon for disseminated silver mineralization on a separate hillside, Cerro Chato, northwest of the Main Zone. Two holes, SA-16-028 and 029, are test reconnaissance holes in the Cerro Chato Zone. These holes have confirmed that Cerro Chato is a favourable target area. More mapping and drilling is being planned for several zones, including Cerro Chato, in the next phase.

Orex's President, Gary Cope says, "Drilling continues to yield thick intercepts of disseminated silver mineralization showing continuity in the Main Zone. Identification of silver on Cerro Chato and in several other areas bodes well for the next phase of exploration."

Kluane Drilling Ltd. provides the drilling services utilizing an environmentally low-impact KD-1000 man-portable diamond drill rig.

Silver mineralization is hosted on the north side of a rhyolite volcanic dome. An altered and highly permeable volcaniclastic unit contains disseminations of silver bearing minerals and broadly spaced stockwork veinlets. The current working model has a porphyritic rhyolite unit as an impermeable cap, which may have focused mineralizing fluids into the host permeable volcaniclastic unit.

True thicknesses are estimated based on structural and stratigraphic interpretations. A map showing the locations of the drill holes and sample cross sections are available on the Orex website.

Orex maintains a QA/QC sampling protocol for the diamond drilling program, including the insertion of commercial analytical standards and blank samples. Analytical testing is performed by SGS Mineral Services and Bureau Veritas. Silver values are determined by fire assay with a gravimetric finish. Multi-element analyses are also determined using a 4-acid digestion and ICP-MS (Inductively Coupled Plasma Mass Spectrometry).

Sandra Escobar Silver-Gold Project, Durango, Mexico

Sandra Escobar is situated north of the town of Tepehuanes, Durango, in the heart of the "Mexican Silver Trend", midway between the mining districts of Tovar and Guanacevi and is 75 km west of Silver Standard's La Pitarrilla. This prolific trend hosts some of the world's largest silver camps and deposits, including Fresnillo, Guanajuato, La Pitarrilla, La Preciosa, Real de Angeles and Zacatecas.

The project consists of 6,976 hectares of mineral concessions and covers multiple mineralized epithermal quartz veins and breccia structures. These veins form a high level silver-gold-base metals system, hosted in andesitic and rhyolitic rocks, centered on a large rhyolite dome complex in the north and silver systems in smaller rhyolite dome complexes to the southeast. Intense alteration zones and fluid flooding in permeable formations indicates the presence of bulk tonnage targets. Excellent infrastructure exists in the Sandra Escobar area, including paved road access, electrical power, water and manpower from nearby communities.
