Orex Minerals Inc. announced that a permit to drill has been received from the Mexican Secretariat of Environment and Natural Resources "SEMARNAT" for the Sandra Silver-Gold Project in northwestern Durango State, Mexico. This is a joint venture between Pan American Silver Corp. (60%) and Orex Minerals Inc. (40%).

Phase-I of this new drilling program will consist of approximately 2,500 to 3,000 metres. Orex and Pan American Silver Corp. completed the Joint Venture agreement to advance exploration and development of the Sandra Silver-Gold Project in 2021, following Pan American's purchase of the interest of Canasil Resources Inc. The Project is a consolidation of two groups of mineral concessions.

Orex is the initial operator of the Project. Throughout 2021 and into early 2022, Orex conducted a geological mapping and lithogeochemical sampling program over the combined 6,970 hectares of the Project. This program was carried out under strict COVID-19 safety protocols and was assisted by the consulting group Geotech Evaluation Services ("GES").

Multiple drill target areas have been identified on the property. Sandra 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. It is also 75 km west of Endeavour Silver's La Pitarrilla deposit.

This prolific trend hosts some of the World's 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 Sandra Property). The Project covers almost 70 square kilometres of contiguous mineral concessions and includes 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, intrusive related vein systems to the west, and silver-bearing 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. An initial mineral resource estimate at Sandra was released in 2016 for the disseminated silver discovery of the Boleras Deposit.

Located at surface in the southeastern part of the Project, the Boleras Deposit contains an Inferred Resource Estimate of 9.8 million tonnes, grading 106 g/t Ag, for a total of 33.3 million ounces of silver. Excellent infrastructure exists in the Sandra area, including paved road access, electrical power, water and manpower from nearby communities. Community engagement is an important part of the ongoing Environmental, Social and Governance (ESG) efforts.
