The Albany Gazette - Avino Announces Inaugural Consolidated Mineral Reserves

"Establishing mineral reserves across all of our properties is a transformational milestone for Avino," said David Wolfin, President and CEO. "For the first time, we have defined reserves that demonstrate the underlying quality, scale, and economic potential of our asset base, further advancing the Company toward a multi-asset, mid-tier producer. We are very pleased to report an inaugural mineral reserve estimate of 127 million silver equivalent ounces across our three assets. This milestone is complemented by growth in our mineral resource base. Importantly, this growth was achieved after accounting for depletion from ongoing mining activities, underscoring the strength and continuity of our ore bodies and mineralized systems. Together, these results reinforce the depth of our organic pipeline and position Avino for continued growth and long-term value creation for shareholders."

HIGHLIGHTS

• Inaugural Proven and Probable Mineral Reserves at La Preciosa and Avino: 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.

• Significant Resource Conversion to Mineral Reserves: 42% of mineral resources were converted to mineral reserves on a silver equivalent basis representing decades of mine life at current mill throughput levels.

• Large Measured & Indicated Mineral Resource Base: 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.

• Increase in All Mineral Resource Categories: Overall, there was a 9% increase in total measured and indicated mineral resources compared to the last published MRE, 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" said Peter Latta, VP Technical Services. "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 our mineral resources to mineral reserves is an incredible accomplishment for the inaugural reserve calculation with room to continue to grow in 2026. Furthermore, with only 4,560 meters drilled between effective dates of resource estimates, we believe there is a lot of room to expand the resource base as we have ramp up drilling and exploration efforts across both La Preciosa and Avino in 2026, with 30,000 metres committed for this year."

MINERAL RESERVE AND MINERAL RESOURCE SUMMARY

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.

Notes for UG Reserves

1. Totals may not sum due to rounding.

2. Underground Mineral Reserves as of October 31, 2025 are derived from Measured & Indicated Resources, account for depletion to that date, and are reported with a reference point of mined ore delivered to the plant.

3. Metal prices considered for the underground Mineral Reserves estimates were US$36.90/t.oz Ag, US$3,210/t.oz Au, and US$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 (US$134.25-68 per dry metric tonne), freight to smelter (US$45 per wet metric tonne), refining charges for silver, gold, and copper (US$0.30/oz Ag, US$6.00/oz Au, and US$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 US$75.31/t, US$55.21/t, and US$60.89/t for mining; US$18.45/t for processing; and US$16.80/t for G&A, respectively, resulting in NSR breakeven cut‑off values of US$110.56/t for Gloria, US$90.46/t for Abundancia, and US$96.14/t for Martha.

4. 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.

6. Based on recent mining costs, Mineral Resources are reported at La Preciosa Ag recovery 80%, Au Recovery 70%, Ag price $36.90/t. oz., Au price $3,210/t. oz. Cut-off grades in silver equivalent grades (AgEQ), Avino Mine - 55 g/t, La Preciosa Underground - 120 g/t, Oxide Tailings -50 g/t.

Mineral Resource Estimation

The definitive estimation methods used were similar for all deposits (Ordinary Kriging), providing a consistent baseline for strategic planning.

Mineral resources were estimated by ordinary kriging, optimized using kriging neighbourhood analysis and verified by means of nearest neighbour and inverse distance methods, swathplot comparisons of estimates and visual inspections. Block models were created for the San Gonzalo, and Avino Vein Systems ET, Guadalupe, La Potosina, La Preciosa and the Oxide Tailings deposit, and estimates were made using industry standard techniques.

Fundamental changes since the previous mineral resource estimates in 2020 and 2024 are (1) depletion due to mining, (2) new sampling and drilling information and (3) changes to the interpretation of the breccias and vein models at Avino ET and La Preciosa.

More sampling information does not always lead to direct increases in resource tonnages and contained metal. In some cases, the new information provides improved understanding (developed by variogram modelling and kriging neighborhood analysis) that may demote some portions of mineral resource from high confidence measured and indicated categories, to a lower confidence inferred category.
