Drills 120 AgEq g/t over 48.40 metres including 1,165 AgEq g/t over 0.33 metres
Avino Silver & Gold Mines Ltd. (TSX: ASM) (NYSE: ASM) (FSE: GV6), releases the results of ten drill holes from below Level 17, the current deepest workings of the mine. The current drill campaign has extended our knowledge of the continuity of the Avino Vein to a distance of 500 meters downdip of the lowest mining level. The exploration program is designed to test the continuity and to improve our understanding of the potential for deeper mineralization. The extent of the Avino Vein has been established to be at least 1,100 metres downdip from surface outcrop. Additionally, a previously undiscovered breccia vein was intersected approximately 15 to 30 metres below the Avino Vein in the footwall intrusive rocks. This unit has revealed three good intercepts (labelled INT-BX in Table 1) including a 35 cm intercept in ET-23-05 yielding 1,165 AgEq g/t. These intercepts warrant further follow-up to see if it can be correlated with historic intercepts in the footwall of the Avino Vein to determine potential continuity.
Highlights
Selected intercepts from the Avino Vein include:
Details are shown in the table and images below.
“The ET area drilling builds on results from our 2022 drill program as well as the January 2023 drill results as we continue to extend the area of mineralization below Level 17,” said David Wolfin, President and CEO. “We drilled 500 metres below our current mine workings to confirm the continuity of mineralization. As we have come to expect with the Avino Vein, the drill intercept widths suggest that this area will be able to be mined by our existing low-cost bulk methods. In addition, we were delighted to discover a new veinlet within the footwall intrusive rock that was very high grade. We include both step out and infill drilling in this campaign and these new step-out holes are obviously not included in the most recent mineral resource estimate released earlier this year.”
Avino is developing a geological model based on a “near porphyry” environment because of the increasing copper grades. The persistence of grade continuity from surface down a plunge distance of over 1,100 metres (800 metres vertical) supports the possibility of a deeper mineralized system that may be linked to a deep porphyry centre.
Geological modelling is ongoing to determine the potential geometry and controls of the mineralization. Our drill program will continue with an additional 4,500 meters planned for the year to bring the total to 8,000 meters of drilling for the year.
Geological Description
The Property contains numerous low-sulphidation epithermal veins (including the Avino vein), breccias, stockworks, and silicified zones that grade into a possible “near porphyry” environment within a large caldera setting. This caldera has been uplifted by regional north-trending block faulting (a graben structure) exposing a window of andesitic pyroclastic rocks of a lower volcanic sequence within this caldera. The lower volcanic sequence is overlain by an upper volcanic sequence consisting of rhyolite to trachyte lava flows and extensive ignimbrites. The direction of the increasing copper grade plunges towards the east in the Avino vein. The changing tenor of the mineralization could be reflecting a transition from epithermal to porphyry-style mineralization.
Below Level 17
A total of ten holes were drilled below level 17 in this drill campaign totalling 3,414 meters. They were completed to investigate the continuity of mineralization in the central part of the ET Area. Nine out of ten holes intercepted mineralization within the vein and stockwork that have silver equivalent grades above the current cut off grade in the latest mineral resource estimate. The results and are reported below in Table 1.
Vein-type mineralization and stockwork containing silver, gold and copper are found along the contacts between intrusive rocks and 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 substantial mineral resources.

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 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, blank reference materials, and duplicates as part of their QA/QC program during assaying.
