AVINO COMPLETES A FURTHER 17 HOLES ON ITS OXIDE TAILINGS PROJECT

 

 

 

 

 

Including 0.79 Au g/t over 10.5 Metres – Oxide Zone

 

Avino Silver & Gold Mines Ltd. (TSX: ASM) (NYSE American: ASM) (FSE: GV6) is pleased to announce drill results from the Oxide Tailings Project that sits within our tailings storage facility #1 on the Avino property.

 

The 2022 drill program included 17 drill holes for a total of 209 metres of drilling. The drilling follows up the 2021 drill program, the results of which were released on April 7, 2022 and can be viewed on our website. The drill holes were added to step out from the current known footprint of the historic oxide tailings deposit to capture the total tailings resource. As mentioned in the previous news release, a comprehensive sampling program is underway to collect samples for an upcoming metallurgical testing program. Once completed and assuming results are positive, the existing PEA will be used as the framework for an updated study with the intention of advancing the project to Pre-Feasibility Study level.

 

The drill results are located below including the total meters drilled:

“These results highlight the continuity of the tailings grade beyond the previous known deposition footprint,” said David Wolfin, President and CEO. “The gold grade in the oxide portion of the recent holes is encouraging and given the distance of the step out holes, we feel this will provide meaningful resource expansion significantly beyond what was described in the previous PEA. The Oxide Tailings project factors prominently into the Company’s growth strategy to achieve intermediate producer status.”

 

Oxide Tailings Project

 

The Oxide Tailings is located to the southwest of the Avino mine and mill and is the current tailings facility for the Avino mill. Over Avino’s 54-year history the mine has operated for various periods of time and as such, generated different types of tailings. There are 3 distinct zones of oxide tailings identified that correspond to the timeline of extraction from the previous historic operations. The historic oxides are tailings that were generated prior to the 1980’s from the open pit mine on Avino’s property. The recent oxides consist of tailings from the processing operation from the 1980’s until the late 1990’s. Finally, the sulfide tailings are the recent tailings from when the operation recommenced in 2011. However as indicated in the above table, the holes drilled in 2022 covered only 2 zones, leaving out the historic oxide zone.

 

Avino is advancing its dry stack tailings project and when complete will decommission the current tailings pond, potentially opening this area to development and reprocessing.

 

The tailings were drilled with a 2″ sonic drill, which was drilled to the depth of the underlying bedrock. The use of the sonic drilling technique provides high quality information and representative granulometry and grade samples and demonstrates Avino’s commitment to technical excellence. The bedrock is sloped so that the depth of each hole can vary significantly depending on the drill hole location. The full table which can also be found on our website under Oxide Tailings Drill Data, details the depth and assay values of each layer of tailings, noting that some of the holes penetrated more than one layer of tailings. The figure below shows the drill holes in plan view.

 

Sampling and Assay Methods

 

Following detailed geological and geotechnical logging, drill core samples are cut in half. One half of the core is submitted to 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. 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.

 

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.
