Vancouver, BC — Orex Minerals Inc. — (TSX-V: REX) ("Orex"), is pleased to announce that the analytical firm SGS Minerals Services has been awarded a contract to conduct the initial metallurgical testing on the Sandra Escobar Project in Durango, Mexico. The Sandra Escobar Project is being advanced by Orex under an option agreement with Canasil Resources Inc. — (TSX.V: CLZ) ("Canasil"). 

A flat-lying unit of strataform, disseminated silver mineralization is located in the southeastern region of the Sandra Escobar project. Preliminary mineralogy testing has identified Native Silver (Ag) as the primary silver mineral, along with the silver halides, Cerargyrite (AgCl) and Bromargyrite (AgBr), hosted within a permeable, crystal lithic tuff. 

Bottle roll leach test will be performed on five composite samples of varying head grades and at three separate crushing particle sizes. The samples will cover the grade ranges of approximately 50, 100, 150, 200 and 250 g/t silver and particle sizes of approximately 80% less than 75, 106 and 150 microns. Sample readings will be taken at 4, 8, 12, 24, 48, 72 and 96 hours to determine leach time performance.

Orex's President, Gary Cope says, "A first metallurgical test is a major step in an exploration project. We look forward to announcing the results of this metallurgical testing, as well as the results of the initial resource estimation." 

SGS Minerals Services is a certified international analytical services company with over 50 years of metallurgical testing experience. SGS has had a metallurgical laboratory in the city of Durango, Mexico, since 2006.

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, disseminations 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. Excellent infrastructure exists in the Sandra Escobar area, including paved road access, electrical power, water and manpower from nearby communities.
