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 September 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”).

Prime Chief Executive Officer Daniel Kunz commented, “With 51,000 metres drilled to date and six drills now turning, we are well on our way to completing 2023’s planned 60,000 metre drill program at Los Reyes. Recent results from both expansion and generative drilling continue to demonstrate solid potential to contribute to resource inventories and develop an outstanding high-grade gold-silver project. Early-stage technical analysis is underway as we advance our understanding of the Los Reyes project. Working with our community partners, we supported a back-to-school program in September. We ended the quarter in strong financial condition to execute on our upcoming plans for 2024 and into 2025.”

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. Since acquiring Los Reyes in 2019, Prime has spent approximately US$32 million on direct exploration activities and has completed over 158,000 m of drilling. On May 2, 2023, Prime announced an updated multi-million-ounce high-grade open pit constrained resource (see below, and refer to Note 1 and the May 2, 2023 press release for more details).

May 2, 2023 Pit Constrained Resource Statement

Drilling is on-going and suggests that the three known main deposit areas (Guadalupe, Central and Z-T) are larger than previously reported. Potential also exists for new discoveries where mineralized trends have been identified outside of the currently defined resource areas.

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.

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.
