News Release
ROCHESTER REPORTS STRONG QUARTERLY RESULTS FOLLOWING
SUCCESSFUL PLANT UPGRADE PROGRAM
Vancouver, British Columbia – May 4 , 2026: - Rochester Resources Ltd. (the “Company” or “Rochester”) (TSXV:
RCT) today reports on its operating results for the quarter ended February 28 th 2026.
Background and Context
The Company has operated in Nayarit since 2006, producing gold and silver from mineralized material . Historically,
the significant manganese content of the mineralized material negatively impacted silver recovery. The unrecovered
silver is in the Company’s tailings impoundment.
The Company has conducted mining operations without a defined mineral resource, and the production decision
was not based on a feasibility study of mineral reserves that has demonstrated technical or economic viability.
As previously disclosed the Company undertook a systematic program of laboratory testing in partnership with the
University of Guanajuato, a leading mining and metallurgy institution in Mexico, to develop a solution to the
manganese problem. A solution was developed and the Company proceeded to design, engineer, and construct a
dedicated addition to the plant to implement the new solution . The work was completed and operations
incorporating the solution commenced operations in Q1 2025.
Operational Results
The results have been positive with recovery for silver recoveries improving markedly.
Combined with improved precious metal prices, the enhanced recovery rates have materially strengthened the
Company's economics through 2025 and into early 2026. Proceeds from operations have been reinvested into
further improvements to both the plant and t he mines, including a broad program of capacity expansion and
equipment rehabilitation.
Plant and Process Upgrades
The reinvestment program has covered all areas of the Company’s mill across the crushing, grinding, filtration, and
proprietary process circuits:
Circuit Upgrades Completed
Crushing Revamping of secondary and tertiary crushers
Grinding Replacement of 5' × 6' ball mill with a larger 6' × 6' unit and corresponding slurry pump
upgrade
Filtration Construction of two new Butter filters; full rehabilitation of existing drum filters
Proprietary Process Installation of two reagent tanks with stainless -steel piping and pumps; large pre -
treatment tank with proprietary propeller design; acidity/basicity control tank; high -
speed centrifugal decanter for liquid-solid separation

The plant investments have translated directly into a significant improvement in financial performance. For the three
months ended February 28, 2026, the Company recorded revenue of $8,419,953, more than double the $3,134,337
reported in the same quarter of the prior year, driven by the higher silver recovery rates and improved metal prices.
The Company generated operating income of $2,304,451, compared to an operating loss of $404,320 in Q3 2025,
and net income of $971,745, compared to a net loss of $2,091,491 in the prior -year quarter.
