Vancouver, British Columbia – March 29, 2022 – Prime Mining Corp. (“Prime”, or the “Company”) (TSX.V: PRYM) (OTCQB: PRMNF) (Frankfurt: O4V3) is pleased to report its operating and financial results for the eight months ending December 31, 2021. Unless otherwise stated, all amounts are presented in Canadian dollars.

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, “With $22 million in cash, strong investor support, and an experienced technical and management team, Prime is well positioned to deliver on our planned Phase 2 exploration program at Los Reyes.  So far, 30,000 metres (“m”) have already been drilled with 9 drill rigs currently on site.  The 8 historical deposits at Los Reyes each have had a significant amount of Prime drilling added to them.  We expect to prepare a new resource report in Q1 of 2023.”

Corporate Highlights During the Quarter

On December 20th the Company announced that it had been added to the MVIS Global Junior Miners Index pursuant to the GDXJ’s quarterly review and rebalancing for the fourth quarter.

Exploration Highlights During the Quarter

On November 17th, the Company provided an update on its planned Phase 2 drill program which is anticipated to run from approximately November 2021 to October 2022 and will consist of approximately 250 new drill holes, for a minimum of 50,000 m. There are currently seven drill rigs operating on the property.

Subsequent Event Highlights

On January 12th the Company announced Noche Buena deposit size expanding at its Los Reyes project with all 13 reported holes encountering potentially economic open pit grade mineralization.

On February 17th the Company announced new drill results from the Z-T Structure located on the far west part of the project, with the holes confirming that the gold-silver mineralization extends from Zapote North to Mariposa, increasing the total length of the gold-silver mineralized Z-T Structure by 450 m to approximately three kilometres.

On March 29th the Company announced continued positive drill results from Phase 1 and the ongoing Phase 2 drill program at Zapote South with 20 holes reported. This drill program which represented the deepest drilling at Zapote, has expanded mineralization by 200 m below the current resource pit to a potential depth of over 300 m below surface.

Maintaining Health and Safety Protocols

The Company successfully minimized the impact of Covid-19 on operations. To-date Covid-19 has not had a material effect on the Company’s activities. Prime remains engaged with local stakeholders and is proactive in monitoring employees and contractors during this uncertain period.

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 km of untested strike length. Los Reyes holds potential for additional discovery and resource expansion.

Prime Mining acquired Los Reyes is 2019, completed initial data compilation, field mapping and trenching in 2020, and in 2021, executed a Phase 1 exploration program that included 25,650 m of drilling. Results suggest the deposits are much larger than previously reported and potential exists for new discoveries outside of current defined resources. The Company is currently undertaking a 50,000 m Phase 2 exploration program.

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.
