Avino Silver & Gold Mines Ltd Announces Inaugural Consolidated Mineral Reserves
Avino Silver & Gold Mines Ltd. has completed a new Mineral Reserve Estimate and updated the Mineral Resource Estimate which includes La Preciosa, the Avino Mine (consisting of the Elena Tolosa deposit, Guadalupe, and La Potosina) with an effective date of October 31, 2025. The Oxide Tailings Deposit mineral reserve estimate was completed in 2024 and is materially unchanged since its publication and has an effective date of January 16, 2024. The proven and probable mineral reserves at the Company’s three assets totaled 27 million tonnes containing 95 million ounces of silver at a grade of 109 g/t, 356 thousand ounces of gold at a grade of 0.41 g/t, and 85 million pounds of copper at a grade of 0.31%. This calculates to 127 million silver equivalent ounces at a grade of 145 g/t. 42% of mineral resources were converted to mineral reserves on a silver equivalent basis representing decades of mine life at current mill throughput levels. Measured and indicated mineral resources across three assets totaled 68 million metric tonnes containing 207 million ounces of silver at a grade of 93 g/t, 413 thousand ounces of gold at a grade of 0.32 g/t and 243 million pounds of copper at a grade of 0.16%. This calculates to 301 million silver equivalent ounces at a grade of 162 g/t. Overall, there was a 9% increase in total measured and indicated mineral resources compared to the last published Mineral Resource Estimate, after accounting for depletion and 4,560 meters of exploration drilling. Measured mineral resources increasing to 10.8 million tonnes from 8.5 million tonnes, indicated resources increasing to 56.9 million tonnes from 44.6 million tonnes, and inferred resources increasing to 24.8 million tonnes from 23.8 million tonnes. La Preciosa Property: Proven and Probable Mineral Reserves of 11 million tonnes containing 72 million ounces of silver at 206 g/t, and 128 thousand ounces of gold at 0.37 g/t. Measured and Indicated Mineral Resources of 33.2 million tonnes containing 158 million ounces of silver at 148 g/t and 287 thousand ounces of gold at 0.27 g/t. Upgrading in confidence of 3.8 million tonnes to the Measured Mineral Resource category, for a total of 23 million ounces of silver at 186 g/t and 36 thousand ounces of gold at 0.30 g/t. Avino Property: Proven and Probable mineral reserves of 10 million tonnes of ore containing 12 million silver ounces at a grade of 38 g/t, and 127 thousand gold ounces at a grade of 0.41 g/t and 85 million pounds of copper at a grade of 0.40%. A measured and indicated mineral resource of 28 million tonnes containing 37 million silver ounces at a grade of 44 g/t and 309 thousand gold ounces at a grade of 0.37 g/t and 226 million pounds of copper at a grade of 0.32%. Oxide Tailings Property: Proven and Probable Mineral Reserves of 6.7 million tonnes of ore containing 12 million ounces of silver at a grade of 54 g/t, and 102 thousand ounces of gold at a grade of 0.47 g/t. The mineral reserve estimates represent an important technical milestone for the Company. The reserves have been developed using established industry methodologies and reflect reasonable prospects for eventual economic extraction based on the data available at the time. Converting nearly half of mineral resources to mineral reserves is an accomplishment for the inaugural reserve calculation with room to continue to grow in 2026. With only 4,560 meters drilled between effective dates of resource estimates, there is room to expand the resource base as drilling and exploration efforts ramp up across both La Preciosa and Avino in 2026, with 30,000 metres committed for this year. As of the effective date of October 31, 2025, Proven and Probable Mineral Reserve estimates at the Company's properties totaled 27 million tonnes for 127 million silver equivalent ounces at a grade of 145 g/t. As of the same date, Measured and Indicated Mineral Resource estimates totaled 67.7 million tonnes and 301 million silver equivalent ounces at a grade of 162 g/t while Inferred Mineral Resources totaled 24.8 million tones and 87.6 million silver equivalent ounces at a grade of 123 g/t. Year-over-year changes primarily reflect discovery and exploration success, Inferred-to-Indicated Mineral Resource conversion, improved geological understanding, and lower cut-off grades supported by higher metal price assumptions, offsetting mining depletion. Measured and Indicated Mineral Resources are reported inclusive of Mineral Reserves, and all Mineral Resources reflect mining depletion through to October 31, 2025. Metal prices considered for the underground Mineral Reserves estimates were USD 36.90/t.oz Ag, USD 3,210/t.oz Au, and USD 4.4/lb Cu. Other key assumptions and parameters include metal recoveries (89% Cu, 74–70% Au, and 87–80% Ag), payable factors applied on a deposit-specific basis (83–96% Ag, 95% Au, and 96.75% Cu), treatment and other smelter charges (USD 134.25–68 per dry metric tonne), freight to smelter (USD 45 per wet metric tonne), refining charges for silver, gold, and copper (USD 0.30/oz Ag, USD 6.00/oz Au, and USD 0.07/lb Cu), and applicable concentrate penalties. Mining, processing, and G&A operating costs for the Gloria, Abundancia, and Martha veins were estimated at USD 75.31/t, USD 55.21/t, and USD 60.89/t for mining; USD 18.45/t for processing; and USD 16.80/t for G&A, respectively, resulting in NSR breakeven cut-off values of USD 110.56/t for Gloria, USD 90.46/t for Abundancia, and USD 96.14/t for Martha. AgEQ grade is estimated considering metal price assumptions, metallurgical recovery for the corresponding mineral type/mineral process and the metal payable of the selling contract as of effective date.
