Intercepts 206 AgEq g/t over 41 metres
Avino Silver & Gold Mines Ltd. (TSX: ASM) (NYSE American: ASM) (FSE: GV6) is pleased to announce further drill results from Phase 2 of its 2021/2022 exploration program.
These latest results represent assays from six holes completed below the current Level 17 mining area, approximately 1,850 metres above sea level at Avino Elena Tolosa area to define the continuity of economic mineralization at depth in the central part of the vein. The drilling results have confirmed the downdip continuity of widths and grades of the Avino vein extending significant potential to a depth of at least 290 metre down dip below current development.
“This ET area drilling below Level 17 is very encouraging and confirms our expectation that not only does the mineralization continue at depth, but it also contains significantly higher copper mineralization as is often the case with porphyry deposits”, said David Wolfin, President and CEO. “Since 2019 following our sale of Bralorne, we have focused our resources on creating value at the Avino property by optimizing production, completing a complimentary property acquisition in La Preciosa and executing an exploration strategy focused on growing the resource base. To execute our exploration strategy, we have expanded our technical team, some of whom, are seasoned geologists having worked on large Mexican mining projects. Avino has been a consistent producer over the years, and we are excited by these high-grade copper intercepts encountered at depth within our permit boundaries and we will continue to pursue value enhancing exploration initiatives across our core assets.”
INTERACTIVE VRIFY 3D MODEL

Current drilling results are 290 metres down dip of Level 17, the lowest developed point of the ET Area of Avino. We are developing a geological model based on the “near porphyry” environment. The persistence of grade continuity from surface down a plunge distance of over 800 metres (600 metres vertical) and base metal zonation supports the likelihood of a deep mineralized system and could possibly be linked to a porphyry centre.”
Geological modelling is advancing to determine the potential geometry and controls of the mineralization. A second drill has been added to this program which includes a total of 13 drill holes for approximately 7, 000 metres of total length for 2022.
The Property contains numerous low-sulphidation epithermal veins (including the Avino vein), breccias, stockwork, and silicified zones that grade into a “near porphyry” environment within a large caldera. The caldera has been uplifted by regional north-trending block faulting (a graben structure), exposing a window of andesitic pyroclastic rocks of the lower volcanic sequence within the caldera. The Lower Volcanic Sequence is overlain by the Upper Volcanic Sequence, consisting of rhyolite to trachyte flows and extensive ignimbrites and intruded by monzonite bodies. The copper / silver ratio in the Avino vein consistently increases from less than 100 above
8 level to over 400 at 17 level and below. The direction of this increase plunges towards the east in the Avino vein, suggesting changing pressure and temperature conditions with depth at the time of mineralization and possibly reflecting a transition from epithermal to porphyry-style mineralization.
Below Level 17
Six holes totalling 3,373 metres drilled were completed to investigate the continuity of mineralization in the central part of the ET Area. Five of the holes intercepted the mineralization within the vein and stockwork and are reported in Table 1.
Vein-type mineralization and stockwork with mineralization of Au, Ag, and Cu are found along the contacts between intrusive rock and an andesite and provide opportunities within the ET Area for the identification and delineation of additional mineral resources that remain open on strike and dip (see Figure 1 for the projections of the resource relative to the drilled holes). The Inclined distance of the Avino vein at the ET Mine from surface is approximately 520 metres as shown in figure 3. This recent deeper drilling suggests that the mineralization persists down dip for an additional 290 metres past the lowest developed mining level. Currently, the mine levels have a vertical separation of 20 metres, suggesting a potential further 14 additional underground levels may be required (depending on economic conditions) to mine the mineralization.
Selected high grade intercepts include:

Sampling and Assay Methods
Following detailed geological and geotechnical logging, drill core samples were cut in half. One half of the core was submitted to the SGS Laboratory facility in Durango, Mexico, and the other half is retained on-site for verification and reference. Gold is assayed by fire assay with an AA finish. Any samples exceeding 3.0 gold grams/tonne are re-assayed and followed by a gravimetric finish. Multi-element analyses are also completed for each sample by SGS ICP14B methods. Any copper values exceeding 10,000 ppm (1%) are assayed using ICP 90Q. Silver is fire assayed with a gravimetric finish for samples assaying over 100 grams/tonne.
Avino uses a series of standard reference materials (SRMs), blank reference materials (blanks), and duplicates as part of their QA/QC program during analysis of assays.
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.
Avino is primarily a silver producer from its wholly owned Avino Mine near Durango, Mexico. The Company’s silver, gold and copper production remains unhedged. The Company’s mission and strategy is to create shareholder value through its focus on profitable organic growth at the historic Avino Property and the strategic acquisition of mineral exploration and mining properties.
