Prime Mining Announces Financial Results and Appoints New Executive

Vancouver, British Columbia – May 11, 2023 – 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 March 31, 2023. Unless otherwise stated, all amounts are presented in Canadian dollars. 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”).

Prime released an updated mineral resource estimate (“MRE”1) for the Los Reyes Gold-Silver Project on May 2, 2023 that included Prime drilling results through December 2022. The MRE contains 1.47 million Indicated gold equivalent (“AuEq”2) ounces at a 1.68 grams per tonne (“gpt”) average grade.  This is 1.0 million ounces of gold at 1.16 gpt and 35 million ounces of silver at 40.4 gpt. The MRE also contains 0.73 million Inferred AuEq ounces at a 1.26 gpt average grade. This is 0.5 million ounces of gold at 0.85 gpt and 18.4 million ounces of silver at 31.5 gpt. The MRE areas remain open along strike and at depth.

Prime is executing an expanded drilling program during 2023 of up to 60,000 metres (“m”).  Prime has already drilled over 20,000 m year-to-date.  About one half of the planned 2023 drilling will occur down dip and along strike within the MRE areas and the other half at multiple new target areas such as Las Primas, Fresnillo, Zapote 300 and the Orito trend.

With a current cash balance of $45.5 million, Prime is funded for the increased exploration drilling program in 2023 and for its expected similar-sized drill program in 2024.  Work will also continue in technical areas such as ongoing metallurgical test work and geotechnical assessments.

  1. Resource estimate is based on economically constrained pits using a $US 1700/ounce gold price, $US 22/ounce silver price, and an assumed 0.22 g/T gold cutoff grade. For more information and other assumptions, please see Prime’s May 2, 2022 press release, or our website.
  2. Gold equivalent grades are calculated as in-situ contained grades, applying the assumed ratio of gold to silver prices using the following formula: AuEq grade (gpt) = Gold grade (gpt) + Silver grade (gpt) x ($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.
