News Releases

Vancouver, BC - Orex Minerals Inc. - (TSX-V: REX - OTCQX: ORMNF) ("Orex"), is pleased to announce that the Phase-III diamond drilling program continues to intercept silver mineralization on the Sandra Escobar Project in Durango, Mexico. These include holes SA-16-049 to SA-16-053 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").

Highlights for this batch of holes in the Main Zone include SA-16-050, which yielded 57.00 metres core length (46.00 m true thickness) grading 118 g/t silver, starting from surface, and SA-16-049, which yielded 41.00 metres core length (35.00 m true thickness) grading 106 g/t silver, also starting from surface.

All five of these drill holes are located on the northern side of the Main Zone. These results extend the mineralized envelope for the Main Zone a further 50 to 100 metres to the north. Also, a low-grade permeable horizon, similar to the Main Zone in texture, has been identified stratigraphically below the Main Zone on several sections and may constitute a bifurcation of the Main Zone, or a new silver target. Intercepts from this lower horizon are marked as "Lower Interval" in the table below.

Orex's President, Gary Cope says, "The third phase of drilling results continues to show strong continuity of the mineralized unit and will be added to the drill hole database for next month's upcoming Resource Estimate."

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

Silver mineralization is hosted in a rhyolite volcanic dome. An altered and highly permeable crystal lithic tuff 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 is 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 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.
