PRIME MINING ANNOUNCES FINANCIAL RESULTS

Prime Mining Corp. has released its operating and financial results for the three-month period ending Sept. 30, 2022. 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, "Phase 2 exploration activities are nearing completion and we continue to make great progress across all three major areas of the project having now drilled over 96,000 metres. During the quarter, step out holes in the Central Zone had discoveries of both mill and heap leach grade mineralization that are expanding the potential resource with drilling continuing to intersect multiple veins down hole. Additional high grade drill results at Guadalupe have also expanded the mineralized envelope there by several hundred metres along strike and down dip. We look forward to receiving additional assays as they become available."

Corporate Highlights During the Quarter

On August 17 th , the Company announced the appointment Mr. Scott Hicks as Executive Vice President bringing over 20 years of experience in mining most recently serving as Senior Vice President Technical Services, Geology and Mine Planning at Kinross Gold Corporation. Mr. Hicks has assumed day-to-day charge over the Company's business development communications and marketing.

Exploration Highlights During the Quarter

On July 18 th , the Company announced positive drill results from 8 drill holes at San Miguel East in the Central Zone Area. The ongoing step out drilling here has made discoveries of both mill and heap leach grade mineralization that are expanding the potential resource at this deposit. Highlight intercepts include:

• 2.7 gpt Au and 130 gpt Ag over 16.9 metres etw
• 4.86 gpt Au and 151.5 gpt Ag over 6.1 metres etw
• 1.88 gpt Au and 283.7 gpt Ag over 2.6 metres etw

On September 7 th , the Company announced new drill results extending Guadalupe at depth and along strike with multiple thick high-grade gold-silver intercepts. Results included 42 in-fill and step-out drill holes which considerably expand the gold-silver mineralization potential at Guadalupe. Highlight intercepts include:

• 5.01 gpt Au and 328.1 gpt Ag over 1.9 metres etw
• 1.65 gpt Au and 235.9 gpt Ag over 13.5 m etw, plus 0.95 gpt Au and 124.5 gpt Ag over 6.0 m etw, plus 2.52 gpt Au and 365.0 gpt Ag over 1.5 m etw
• 1.46 gpt Au and 56.3 gpt Ag over 14.4 m etw, plus 1.01 gpt Au and 67.2 gpt Ag over 1.5 m etw

Advisory Agreement Renewed

On June 8th, the Company renewed a services agreement between Trinity Advisors Corporation for a 2-year term expiring June 8, 2024. The agreement was subsequently amended on September 8th to revise the compensation terms. Pursuant to the agreement, the Company is required to pay a fee of $112,500 every six months during the term of the agreement, with the first payment occurring on or before December 8, 2022.

Community Engagement and Environmental Stewardship Strategy

We strive to minimize the environmental impact of our activities and ensure that Los Reyes has a positive impact on our host communities.

During the quarter the Company provided assistance to the local community to mitigate the damage caused by the heavy rains on the roads. In addition to helping clear rocks off the main road for access, the Company waterproofed the local church and provided water pumps and water diversion techniques to prevent future road closures.

Additionally, the Company provided air conditioning units and whiteboards to the local school which was greatly appreciated.

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.
