VANCOUVER, BC, March 2, 2021 /CNW/ - Orex Minerals Inc. (TSXV: REX) (OTCQB: ORMNF) ("Orex") is pleased to announce that it has entered into a joint venture agreement (the "Joint Venture") with Pan American Silver Corp. (TSX: PAAS) (NASDAQ: PAAS), through its subsidiary Plata Panamericana S.A. de C.V. ("Pan American"), to further explore and develop the Sandra-Escobar Project, in Durango State, Mexico (the "Project"). The intention of the parties to form the Joint Venture was previously announced by Orex on March 26, 2020.

The Project is a consolidation of two groups of claims, each controlled by the two Joint Venture participants. Orex and Pan American own a 40% and 60% interest, respectively, in Empresa Minera Sandra-Escobar, S.A. de C.V. (the "Joint Venture Company"), the new joint venture company formed to hold the Project. Orex will be the initial operator of the Project.

Under the terms of the Joint Venture, Pan American and Orex are obligated to make contributions to the Joint Venture Company in proportion to their respective ownership interests, subject to the terms and conditions of the joint venture agreement. Orex intends to finalize an initial program and budget with Pan American and commence work on the Project as soon as possible.

Orex's President and CEO, Ben Whiting, said; "This is an excellent opportunity to consolidate the majority of the mineral district. There are multiple precious metal targets, as well as the existing Boleras Silver Deposit. We at Orex look forward to working with Pan American to advance the Sandra-Escobar Project."

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 SSR Mining Inc.'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. Mineralization hosted on adjacent and/or nearby properties is not necessarily indicative of mineralization hosted on the JV's property.

The Project consists of the Sandra Property of 6,335 hectares and Escobar Property of 635 hectares of mineral concessions and covers multiple mineralized epithermal quartz veins, disseminated horizons and breccia structures. These mineralized features 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 area, including paved road access, electrical power, water and manpower from nearby communities.
