AVINO DRILLS 1,638 G/T SILVER OVER 7.90 METRES INCLUDING 15,352 G/T SILVER
OVER 0.37 METRES AT LA PRECIOSA
Avino Silver & Gold Mines Ltd. (ASM: TSX/NYSE American, GV6: FSE, "Avino" or "the Company") reports results of four drill
holes from La Preciosa which were drilled to twin previous drilling. Assay results for the intercepts of the La Gloria and
Abundancia veins were very positive and are shown in Table 1.
Selected Intercept Highlights:
• Hole PMLP 25-03: 1,638 g/t Ag and 1.92 g/t Au over 7.90 metres true width
o including 15,352 g/t Ag and 1.55 g/t Au over 0.37 metres true width
• Hole PMLP 25-04: 544 g/t Ag and 0.46 g/t Au over 6.42 metres true width
o including 1,739 g/t Ag and 0.74 g/t Au over 0.66 metres true width
The variation of grades and thicknesses within relatively short distances (under 10 metre s) compared with previously
drilled intercepts were expected due to the “pinch and swell” geometry of the La Preciosa veins and the high nugget
effects. The drill results exceeded grade expectations and verified the geometry of the current vein-based resource model.
Higher grades intersected in the north ern portion of the La Gloria Vein (in hole PMLP -25-02) are expected to continue
further to the North and warrant additional step -out drilling to potentially expand the mineral resource defined on the
shallow La Gloria Vein.
"We are delighted to report excellent grades on all four holes at La Preciosa. The intercept grades are significantly higher
than the average grades outlined in our current resource, highlighting the potential we aim to capture by using
underground mining methods. In addition, the larger widths encountered at both La Gloria and Abundancia were a
welcome surprise underscoring that there is still much to learn about this deposit despite the 1,500 drill holes and
substantial exploration investment performed by previous operato rs,” said David Wolfin, President and CEO. “We will
integrate these results into our ongoing geological model and continue drilling some of the underexplored areas of the
named and unnamed veins. We will also combine this information with the data from channel sampling already underway
as our mine development plan has us intersecting both veins during the current ramp advancement”.
Drilling Results
Assays have been received on four holes totalling 1,100 metres drilled at La Preciosa, intersecting the La Gloria vein in all
four holes, the Abundancia vein in three holes, and additional unnamed veins in three of the holes. Assays were processed
under Avino’s standard QA/QC program, with no indications of bias or contamination detected. Unlike the Avino Mine,
the La Preciosa deposit contains no notable copper mineralization, so no copper values are reported.

Geological Description
La Preciosa deposit is situated on the eastern flank of the Cretaceous to mid -Tertiary Sierra Madre Occidental. The SMO
is the largest silicic igneous province in North America, and it stretches from the USA -Mexico border to the latitude of
Guadalajara, where the SMO is covered by the late Miocene to Quaternary Trans-Mexican Volcanic Belt.
Mineralization at the La Preciosa is hosted within multiple discrete poly -phase quartz veins, often displaying banded,
smoky, drusy, and chalcedonic textures. Also, in each stage, there is variably crustiform banded fracture fill/breccia cement
mineralogy. Fluorite, amethyst, a substantial number of barite laths, calcite, and rhodochrosite may also be present, and
sulphide mineralization in the form of sphalerite, galena, pyrite, chalcopyrite, acanthite, sparse native silver, and free gold,
as well as iron and manganese oxides have been noted in drill core. The principal silver-bearing mineral at the La Preciosa
is acanthite-pseudomorphic after argentite or as microcrystalline to amorphous grains.
The main vein system on the Abundancia ridge consists of dominantly north -south-striking and westward-dipping veins
plus east -southeast –striking, south -dipping crosscutting veins. The Abundancia vein system has been traced on the
surface for over 1.5 km. In the eastern part of the Project, a north- to northwest-striking, shallow west-dipping vein system
with associated hanging wall veinin g and alteration is exposed in a series of hills. This vein system is referred to as the
Martha vein and has been traced by drilling for over 2.5 km along the strike.
The mineralization in the area occurs in veins, veinlets, and stockwork. These veins average in true width less than 15 m
(Martha Vein) and consist of several stages of banded crustiform to colloform, quartz (and cryptocrystalline quartz at
shallow depths), adularia, barite, and typically later carbonates (both calcite and rhodochrosite); illite commonly replaces
the adularia. There are variable amounts of pyrite, sphalerite, and galena plus argentite, and variable amounts of
tetrahedrite - tennantite, freibergite, and Ag sulfosalt.
There are steep-dipping veins in the west, such as the La Gloria vein. These steep veins can be considered as a mineralized
zone or lode of stock work, silicification, breccias, veins, vein breccias, veinlets, and a general mix of multiple styles of
mineralization.
The mineralization displays characteristics typical of epithermal veins in Mexico, particularly of the Ag-rich variety. Quartz
veins are accompanied by adularia, barite, calcite, and rhodochrosite of variable timing, as well as acanthite, freibergite,
Ag sulfosalts and minor electrum, plus variable amounts of pyrite, honey -coloured sphalerite, tennantite/tetrahedrite,
chalcopyrite and galena, and supergene Fe and Mn oxides; the hypogene minerals are characteristic of intermediate -
sulphidation deposits in Mexico. Mineralization is believed to be Tertiary in age, and both the Lower Volcanic Supergroup
(LVS) and Upper Volcanic Supergroup (UVS) are mineralized, but the overlying basalts are recent and not mineralized.
Sampling and Assay Methods
Following detailed geological and geotechnical logging, selected drill core areas were cut in half. One half of the core was
submitted to the SGS Laboratory facility in Durango, Mexico, and the other half was retained on -site for verification and
reference. Gold is assayed by fire assay with an AA finish. Any samples exceeding 3.0 gold g/t are re-assayed and followed
by a gravimetric finish. Multi-element analyses are also completed for each sample by SGS ICP14B methods. Silver is fire
assayed with a gravimetric finish for samples assaying over 100 g/t . Avino uses a series of standard reference materials,
blank reference materials, and duplicates as part of their QA/QC program during assaying.
Qualified Person(s)
Avino's projects in Durango, Mexico are under the geoscientific oversight of Michael F. O’Brien, P.Geo., Senior Principal
Consultant, Red Pennant Communications, and under the supervision of Peter Latta, P.Eng, Avino’s VP, Technical Services,
who are both qualified persons within the context of NI 43 -101. Both have reviewed and approved the technical data in
this news release.

Cautionary note to U.S. Investors concerning estimates of Mineral Reserves and Mineral Resources
All reserve and resource estimates reported by Avino were estimated in accordance with the Canadian National Instrument 43-101 and the Canadian
Institute of Mining, Metallurgy and Petroleum (“CIM”) Definition Standards. The U.S. Securities and Exchange Com mission (“SEC”) now recognizes
estimates of “measured mineral resources,” “indicated mineral resources” and “inferred mineral resources” and uses new defini tions of “proven
mineral reserves” and “probable mineral reserves” that are substantially similar to the corresponding CIM Definition Standards. However, the CIM
Definition Standards differ from the requirements applicable to US domestic issuers. US investors are cautioned not to assume that any “measured
mineral resources,” “indicated mineral resources, ” or “inferred mineral resources” that the Issuer reports are or will be economically or legally
mineable. Further, “inferred mineral resources” are that part of a mineral resource for which quantity and grade are estimated on the basis of limited
geologic evidence and sampling. Mineral resources which are not mineral reserves do not have demonstrated economic viability.
Neither TSX nor its Regulation Services Provider (as that term is defined in the policies of the TSX) accepts responsibility for the adequacy or accuracy
of this release.
