Permit Received and Plans Underway for Diamond Drilling on the Sandra

Silver-Gold Project in Durango, Mexico

VANCOUVER, BC

,

May 3, 2022

/CNW/ -

Orex Minerals Inc.

– (TSXV: REX) (OTCQB: ORMNF) ("

Orex

") is pleased to announce 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's President & CEO,

Ben Whiting

, P.Geo., states:

"It is good to start a new phase of exploration on this target rich precious metals property. We also

appreciate this opportunity to work with our talented joint venture partners to advance the Sandra Project."

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 SILVER-GOLD PROJECT,

DURANGO, MEXICO

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 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 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 (see news release

31 October 2016

).

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.
