VANCOUVER, BC, Avino Silver & Gold Mines Ltd. (TSX: ASM) (NYSE American: ASM) (FSE: GV6), “Avino” or “the Company”) is pleased to announce drill results from the La Potosina area of the Avino property.
The 2021 drill program included 2,400 metres of drilling at La Potosina. An area of the Avino property that has been known to host high-grade, low sulphidation style mineraliation similar to that encountered at Avino’s San Gonzalo Mine. The La Potosina area is only 3 kilometres from the San Gonzalo Mine and just 5 kilometres from the mill facilities at the Avino Mine.
Following Up on Historic Data Which Returned 2,737 g/t AgEq Over 0.40 Metres Within 329 g/t AgEq Over 6.30 Metres
Just over 10 years ago drilling at La Potosina identified near surface structure similar to the San Gonzalo Vein and was continuous for 300 metres and had a vertical extension of 1,000 metres. A recent surface rights agreement was reached in early 2021 with the local landowner and as a result this area has become a high priority for Avino.
Highlights from the 2021 drill program are as follows:
Hole LP-21-06 from 333.05m to 337.45m returns 4.40 metres at 270 g/t Ag, 2.5% Zn and 0.9% Pb (463 g/t AgEq)
Including 333.05m to 333.25m returns 0.20 metres at 1,257 g/t Ag, 4.4% Zn and 2.8% Pb (1,641 g/t AgEq)
Including 335.55m to 335.90m returns 0.35 metres at 510 g/t Ag, 5.0% Zn and 2.2% Pb (918 g/t AgEq)
Including 335.90m to 336.35m returns 0.45 metres at 406 g/t Ag,4.2% Zn and 1.3% Pb (717 g/t AgEq)
Hole LP-21-07 from 151.70 to 154.65 returns 2.95 metres at 617 g/t Ag and 0.40 g/t Au (668 g/t AgEq)
Drill results are located in a table at the end of this release and includes historical data.
Our 2022 plans include an additional 40 holes with 6,000 metres of drilling.
“We are excited to continue exploring the La Potosina area and I want to commend our personnel on site who were able to negotiate the surface rights agreement,” said David Wolfin, President and CEO. “Following our exploration strategy discussed previously, La Potosina factors in prominently as one of our high-grade, near surface targets. This target has the potential to supplement our current feed to the mill in the near to medium term. We are excited to continue exploring this area and it will be a focus for our 2022 exploration plans.”
La Potosina Vein
The La Potosina Vein is a typical low-sulfidation epithermal structure and is similar to the San Gonzalo Vein previously mined at the San Gonzalo Mine. The La Potosina Vein is NW-trending and dips towards the southwest. The vein consists of multiple quartz phases, with adularia, rhodonite, disseminated pyrite, arsenopyrite, as well as base metal sulfides such as galena and sphalerite, and chalcopyrite occurs as a minor component and becomes more prominent with increasing depth below surface. Higher silver grades in the La Potosina Vein appear to occur at elevations 2,100 metres above sea level. The silver minerals consist of silver sulfosalts such as pyrargyrite and proustite that commonly form in low temperature environments and some minor argentite. Abundant galena (associated with silver and sphalerite) are present in Hole LP-21-06, at a relatively low elevation of 1,900 metres above sea level, suggesting a source in the base sulfide zone.
The ongoing exploration model will focus on verifying the continuity of the vein along strike trending NW at elevations above 2,100 metres while looking for favorable dilation structures in the northwest.
Sampling and Assay Methods
Following detailed geological and geotechnical logging, drill core samples are sawed 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 grams/tonne gold 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.
The sampling and assays methods for the historical data at La Potosina from 2011 was submitted to Inspectorate lab, (as it was formally known, and is currently named Bureau Veritas), a facility in the City of Durango and used the diamond core sampling method.
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.
