Prime is focused on the exploration and development of its wholly owned Los Reyes Gold-Silver Project in Sinaloa State, Mexico (“Los Reyes” or the “Project”).

Prime Chief Executive Officer Daniel Kunz commented, “We are currently into the rainy season at Los Reyes but still have 5 drill rigs operating and already have completed 63,000 metres of drilling in Phase 2, for a total of 88,500 metres Phase 1 and 2 combined.   In July 2022, the Company reported results from eight drill holes at the San Miguel East deposit, which were drilled down dip of the known structure at depth. All eight encountered mineralization with seven of the eight extending mineralization beyond the current historic resource. The southernmost hole, 22SME‐11, with an 18‐metre intercept returning 2.72 gpt Au and 129.8 gpt Ag (16.9 m etw), was intersected outside the previously reported pit‐constrained resource.”

Exploration Highlights During the Quarter

On April 12

^th

, the Company announced positive drill results from 26 drill holes into its Guadalupe East deposit. These holes intercepted the high-grade Estaca, the San Nicolas and the San Manuel epithermal veins as well as other sub-parallel veins in the system.

On May 2

^nd

, the Company announced new drill results expanding the Zapote North deposit. These results included 17 new holes targeting the northern extension of the Z-T Structure, including 2 holes from the Mariposa deposit. This drilling confirmed that gold-silver mineralization extends from Zapote North to Mariposa.

On June 1

^st

, the Company announced 12 new step-out drill holes at the Guadalupe East deposit. Six of these holes interested high-grade gold and silver mineralization below the current pit-constrained resource which demonstrated the strong potential for near-pit resource expansion.

On June 29

^th

, the Company announced 20 additional assays from its expanded Phase 2 step-out and infill drilling program at the Tahonitas deposit on the western side of the project. These results continued to successfully identify shallow near surface mineralization as well as deeper mineralization down to 450 metres above sea level.

Los Reyes Gold and Silver Project

Los Reyes is a rapidly evolving high-grade, low sulphidation epithermal gold-silver project located in Sinaloa, Mexico, within the prolific Sierra Madre mining region. Historic operating results indicate that an estimated 1 million ounces of gold and 60 million ounces of silver were recovered from five separate operations at Los Reyes between 1770 and 1990. Prior to Prime’s acquisition, recent operators of Los Reyes had spent approximately USD 20 million on exploration, engineering, and prefeasibility studies. The Project remains underexplored as only 40% of the known structures have been systematically drilled, leaving 10 kilometres of untested strike length. Los Reyes holds potential for additional discovery and resource expansion.

Since acquiring Los Reyes in 2019, Prime has spent approximately US$30 million on direct exploration activities and is nearing completion of two phases of comprehensive drilling totaling over 87,000 metres and growing. Results to date suggest the eight known deposits are much larger than previously reported and potential exists for new discoveries outside of current defined resource areas.

About Prime Mining

Prime Mining is an ideal mix of successful mining executives, strong capital markets personnel, and experienced local operators focused on unlocking the full potential of the high-grade Los Reyes Gold-Silver Project in Mexico. Prime Mining has a well-planned capital structure with significant team and insider ownership.
