Avino Extends Mineralization Below Mine Workings
Drills 150 AgEq g/t over 26.77 metres including 1,800 AgEq g/t over 0.28 metres
VANCOUVER, BC, Oct. 11, 2022 /PRNewswire/ - Avino Silver & Gold Mines Ltd. (TSX: ASM) (NYSE American: ASM) (FSE: GV6) ("Avino" or "the Company") has now compiled further drill results from Phase 2 of its 2021/2022 exploration program.
These latest results represent six holes completed below the current Level 17 mining area at the Elena Tolosa ("ET") area of the Avino Mine. The goal of this part of the exploration program is to define the continuity of the steeply dipping mineralization and to identify the source of the mineralization's feeder. These drilling results demonstrate the continuity of our mineralization similar to or higher than the current mining widths and grades at the lowest level of the current Avino Mine production area.
"The ET area drilling builds on our June 2022 results as we as continue to expand the area of mineralization below Level 17", said David Wolfin, President and CEO. "We are thrilled at the copper grades over significant widths and encouraged to see strong gold and silver grades as well. In the last drill campaign, we drilled to a depth of 290 metres below the lowest mining level. This current drill campaign tested infill sections to a depth of 232 metres to ensure continuity as well as extensions to the east of the known mineralization. Furthermore, we also tested on the eastern edge of our production workings to add to our geological understanding and help identify the main mineralization feeder. With this continued success, our team is extremely excited on ET prospects and have made the decision to mobilize Avino's 3rd exploration drill rig to these areas. The current intercept widths suggest that this area will be able to utilize Avino's existing low-cost bulk mining methods."
Avino is developing a geological model based on a "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 deeper mineralized system and could possibly be linked to a porphyry centre.
Geological modelling is ongoing to determine the potential geometry and controls of our mineralization. A further 6 drill holes are planned and budgeted for 2022.
The Property contains numerous low-sulphidation epithermal veins (including the Avino vein), breccias, stockworks, and silicified zones that grade into a "near porphyry" environment within a large caldera setting. 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 this caldera. This lower volcanic sequence is overlain by an upper volcanic sequence, consisting of rhyolite to trachyte lava flows and extensive ignimbrites that have been intruded by monzonite bodies. The direction of the copper grade 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.
Six holes totalling 3,269 meters 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 silver, gold and copper are found along the contacts between intrusive rocks and an andesite. This provides 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). This recent deeper drilling confirms that the mineralization persists down dip significantly past the lowest developed mining level and may prove to add significant mineral resources subject to the completion of an updated mineral resource estimate currently scheduled for Q1 2023.
"In my opinion, the strong vertical persistence of the mineralization system and three centuries of mining history are signs that Avino may turn out to be a substantial deposit." said Michael F. O'Brien, P.Geo., Senior Principal Consultant, Red Pennant Communications.
Selected intercepts include:
Hole ET 22-08: 95 AgEq g/t over 43.80 metres, including 673 AgEq g/t over 0.66 metres
Hole ET 22-09: 150 AgEq g/t over 26.77 metres, including 1,037 AgEq g/t over 0.46 metres and 1,800 AgEq g/t over 0.28 meters

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.
