CONTINUING EXCEPTIONAL DRILL RESULTS FOR AVINO
Avino Silver & Gold Mines Ltd. has released the results of four drill holes from below Level 17, the current deepest workings at the Elena Tolosa (ET) area of the Avino system. In July of this year, the Company reported the best drill intercept in the Company's history with a step-out drill hole in the same area. These latest deep step-out holes test the SW extent of the robust Avino vein and one infill hole was drilled to confirm local continuity. The current drilling follows the continuity of the steeply dipping mineralization and aids in understanding the deep source of the mineralization. Avino has enlisted a number of world-renowned consulting geologists to contribute to the geological understanding of the mineralization characteristics. The known depth extent to date of at least 750 metres of mineralization is significant and is unusual in comparison with most Mexican epithermal deposits.
Selected Intercept Highlights:
- Hole ET 23-13: 0.70 % Cu, 31 Ag g/t and 0.21 Au g/t over 44.40 metres true width
- including 1.10 % Cu, 42 Ag g/t and 0.58 Au g/t over 9.85 metres true width
- Hole ET 23-10: 0.39 % Cu, 36 Ag g/t and 0.07 Au g/t over 27.15 metres true width
- including 0.47 % Cu, 59 Ag g/t g and 0.09 Au g/t over 13.2 metres true width
Details are shown in the table and images below.
"We are excited to report that we hit substantial widths at grades well above our current cutoff grade on all four drill holes as we look to define the mineralization limits at depth," said David Wolfin, President and CEO. "In addition, we have continued to define the hanging wall breccia which is an offshoot of the main Avino Vein that originates from surface. The access to this breccia is relatively easy through existing development works and we are currently evaluating a mine plan to incorporate these resources into our near to medium term plans. We were also surprised with an intersection of a stock work vein close to surface which indicates the complex and distributed nature of the stockwork system that accompanies the thick, main Avino vein. We will take these results and incorporate them into the next phase of our exploration plans."
Avino is developing a geological model based on a "near porphyry" environment because of the increasing copper grades with depth. The persistence of silver and copper grade continuity from surface down a plunge distance of over 1,100 metres with increasing copper grades supports the possibility of a deeper mineralized system which may be linked to a porphyry centre.
Geological modelling is ongoing to determine the potential geometry and controls of the mineralization. Avino has completed its planned and budgeted drilling program for the year by drilling 7,545 metres in 13 drill holes. The team of geologists on site are working through the recommendations made by the structural geologists to further study the potential of the entire ore body. The 2023 results will be further reviewed to determine exploration plans and budget for 2024.
Below Level 17 Four holes totalling 2,040 meters, were drilled below Level 17 in this drill campaign. They were completed to investigate the continuity of mineralization in the central part of the ET Area of Avino system. All four 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 are reported below in Table 1 .
Vein-type mineralization and stockwork containing silver, gold and copper have been found along the contacts between intrusive rocks and an andesite unit. 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 drilling confirms that mineralization persists to the west along strike at depth and that there is potential for high silver and gold grades associated with the increasing copper grades that have been drilled at depth.
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 steeply towards the east in the Avino vein. The changing tenor of the mineralization could be reflecting a transition from epithermal to porphyry-style mineralization.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.
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.
Avino is a silver producer from its wholly owned Avino Mine near Durango, Mexico. The Company's silver and gold 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 the La Preciosa property. Avino currently controls mineral resources, as per NI 43-101, that total 368 million silver equivalent ounces, within our district-scale land package. We are committed to managing all business activities in a safe, environmentally responsible and cost-effective manner, while contributing to the well-being of the communities in which we operate.
