ASM Avino Silver and Gold Mines Ltd

VANCOUVER, BC, Feb. 16, 2023 /PRNewswire/ - Avino Silver & Gold Mines Ltd. (TSX: ASM) (NYSE: ASM) (FSE: GV6) has completed an updated mineral resource estimate ("MRE") that includes the Elena Tolosa ("ET") deposit, the San Gonzalo deposit, and the Oxide Tailings deposit. Inaugural MREs have also been included on the Guadalupe and La Potosina deposits.

• 161 million measured and indicated silver equivalent ounces, an increase of 38%, made up of:
• 70 million silver ounces, an increase of 35%
• 136.7 thousand copper tonnes, an increase of 18%
• 596 thousand gold ounces, an increase of 23%, contained in:
• 34.7 million measured and indicated metric tonnes, increase of 28% overall, also
• 70 million inferred silver equivalent ounces, an increase of 90%

• 5.7 million tonnes of measured and indicated mineral resources, an increase of 407%
• 17.4 million measured and indicated silver equivalent ounces, an increase of 287%

1. Figures may not add to totals shown due to rounding. All ounces are troy ounces.
2. Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability.
3. The Mineral Resource estimate is classified in accordance with the Canadian Institute of Mining, Metallurgy and Petroleum's (CIM) Definition Standards for Mineral Resources and Mineral Reserves incorporated by reference into National Instrument 43-101 (NI 43-101) Standards of Disclosure for Mineral Projects.
4. Based on recent mining costs Mineral Resources are reported at AgEq cut-off grades of 60 g/t, 130 g/t, and 50 g/t for ET, San Gonzalo, and Oxide Tailings, respectively. The cut-off grades for Guadalupe and La Potosina are 100 g/t.
5. AgEQ or silver equivalent ounces are notional, based on the combined value of metals expressed as silver ounces.
6. The silver equivalent was back-calculated using the following formulas:
   
   1. ET, Guadalupe, La Potosina: AgEq (g/t) = Ag (g/t) + (71.43 x Au (g/t) + (113.04 x Cu (%))
   2. San Gonzalo: AgEq (g/t) = Ag (g/t) + (75.39 x Au (g/t))
   3. Oxide Tailings: AgEq (g/t) = Ag (g/t) + (81.53 x Au (g/t))
7. Cut-off grades were calculated using the following consensus metal price assumptions: gold price of US$1,800/oz, silver price of US$21.00/oz, and copper price of US$3.50/lb.
8. Metal recovery is based on operational results and column testing.

Avino President and CEO, David Wolfin commented: "We are thrilled to deliver this updated mineral resource representing another milestone for Avino on our path to transformational growth. This update is a significant boost to our overall consolidated mineral resources at the Avino property, with the new ounces coming in at a cost of $0.05 per discovered silver equivalent ounce - an incredible achievement. The updated mineral resource estimate provides us with a strong long-term outlook. We have increased the grade at ET, added significant silver and gold resources to both the measured and indicated category for the oxide tailings deposit, and put out an inaugural resource for the exciting recently explored areas.  Together with the previously reported mineral resources on our new La Preciosa property, the consolidated mineral resources total 368 million silver equivalent ounces in the measured, indicated, and inferred categories. The Avino property is a long-life asset. Finally, I would like to express my appreciation to the entire Avino team for their contributions in this achievement of resource increase. The 2023 exploration program is underway with 8,000 metres of drilling planned."

The total measured and indicated mineral resource tonnage in all deposits totals 34.6 million metric tonnes containing
160.8 million ounces of silver equivalent, comprised of 69.96 million ounces of silver, 596,650 ounces of gold, and 301.4 million pounds of copper.

The total inferred mineral resource tonnage in all deposits totals 19.3 million metric tonnes, consisting of 69.61 million ounces of silver equivalent comprised of 28.42 million ounces of silver, 212,640 ounces of gold, and 158.49 million pounds of copper.

The ET deposit has been sampled in underground development below elevations of 360 metres to 470 metres below surface, and it has been discovered to be consistently mineralized between the hanging wall and footwall veins over a thickness of up to 45 metres. This broad zone has been proven by underground development and channel sampling down to an elevation of 1,849 metres above sea level and remains open below. The Mineral Resource at the ET deposit has been updated based on 3D models of underground development and stoping excavations less all production since the last resource update.

Our strategy of phased exploration drilling to deeper levels, followed by ramping and development continues to be cost effective and mitigates risk as the ET deposit is developed to deeper levels. Remarkably, the ET deposit continues to reveal mineralized extensions nearly five hundred years since the beginning of mining.

The Oxide Tailings resource has been updated with the additional 127 drill holes drilled in 2022 which has added significant confidence in the block model and significantly increased mineral resources in all categories. Sonic drilling proved to be a very efficient tactic in confirming the tailings deposit. The Oxide Tailings deposit provides significant potential for future production, with detailed metallurgical test work already completed and an upcoming prefeasibility study to be started within 2023.

These vein deposits are being included in the resource statement for the first time. The Guadalupe deposit is less than one kilometer from the Avino processing plant.

The definitive estimation methods used were substantially the same for all three 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 and the Oxide Tailings deposit, and estimates were made using industry standard techniques.

Fundamental changes since the previous mineral resource estimates in 2020 are (1) depletion due to mining (over 550 thousand tonnes milled), (2) new sampling and drilling information and (3) changes to the interpretation of the brecias and vein models at ET.

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.

For the San Gonzalo and Avino Vein Systems, estimated blocks with average distances more than 80 metres from samples have been classified as inferred resources. For the San Gonzalo Deposit, estimated blocks with average distances more than 30 metres from samples have been classified as inferred resources.

For the Oxide Tailings, estimated blocks more than 60 metres from samples are not included in the indicated category resources.

For La Potosina and Guadalupe, estimated blocks more than 30 metres from samples are not included in the indicated category resources.

The mineral resources estimate is being included in an updated technical report prepared by Tetra Tech Inc. under National Instrument 43-101 ("NI-43-101"), which will be available on SEDAR (www.sedar.com) under the Company's profile and filed on Form 6-K with the SEC within 45 days.
