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 veining 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.

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 Commission ("SEC") now recognizes estimates of "measured mineral resources," "indicated mineral resources" and "inferred mineral resources" and uses new definitions 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.
