PRYM Prime Mining Corp

Prime Mining Corp. (“Prime”, or the “Company”) (TSX.V: PRYM) (OTCQX: PRMNF) (Frankfurt: O4V3) is pleased to report its operating and financial results for the quarter ended June 30, 2023. Prime is focused on the exploration and development of its wholly owned high-grade Los Reyes Gold-Silver Project in Sinaloa State, Mexico (“Los Reyes” or the “Project”).

The Company also announces a change to its board of directors: effective August 16, 2023, Mr. Kerry Sparkes is appointed to the board of directors, replacing Mr. Paul Larkin who has stepped down. Mr. Sparkes is a Technical Advisor to Prime, with over 30 years’ experience in mineral exploration as an exploration geologist and mining executive. He was past Vice President Geology for Franco-Nevada Corporation, where he was responsible for evaluating global mineral deposits, and co-founder and director of Orla Mining Ltd. Mr. Sparkes is a registered professional geologist and Qualified Person.

Prime Chief Executive Officer Daniel Kunz commented, “We thank Paul Larkin for his many contributions to the Company and wish him the best in his future endeavours. We have already benefitted tremendously from Kerry Sparkes’ significant geology and project experience, and continue to look forward to his additional involvement as a member of our Board of Directors.   Prime concluded a very productive second quarter 2023. We materially increased our cash balance which currently stands at $41 million, published a new 2023 Los Reyes Mineral Resource Estimate, initiated Prime’s annual ESG sustainability reporting, and welcomed a new member to our senior management team. At Los Reyes, drilling encountered wide and high-grade intercepts in Z-T and Central Zones resource areas. We are drilling in areas that can increase the current resource size and quality through discovery of adjacent and new zones of gold-silver mineralization. We have already completed more than 37,000 metres of our drilling in 2023. Work is also ongoing in several technical areas including metallurgical test work.”

Notes

1. Mineral Resource Estimate is based on economically constrained pits using a $US 1700/ounce gold price, $US 22/ounce silver price, and an assumed 0.22 gpt gold cutoff grade. For more information and other assumptions, please see Prime’s May 2, 2022 press release, or our website.
2. Gold equivalent (“AuEq”) grades are calculated as in-situ contained grades, applying the assumed ratio of gold to silver prices using the following formula: AuEq grade (gpt) = Gold grade (gpt) + Silver grade (gpt) x ($US 22 / $US 1700). Relative recoveries are not considered in the in-situ contained grade estimate but are assumed to have mill recoveries of 93% and 83% for gold and silver, respectively and heap leach recoveries of 73% and 25% for gold and silver, respectively. For more information and other assumptions, please see Prime’s May 2, 2022 press release, or our website.

Los Reyes Gold and Silver Project

Los Reyes is a rapidly evolving high-grade, low sulphidation epithermal gold-silver project located in Sinaloa State, Mexico. 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 US$20 million on exploration, engineering, and prefeasibility studies. The Project remains underexplored and 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 has completed two phases of comprehensive drilling totaling over 110,000 m. Results to date suggest the three known main deposit areas, Guadalupe, Central and Z-T are much larger than previously reported. Potential exists for new discoveries outside of the 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.
