Avino Silver & Gold Mines Ltd.: San Gonzalo Mine-Level 5 Underground Development Results

Marketwired

VANCOUVER, BRITISH COLUMBIA--(Marketwired - Oct. 1, 2013) - Avino Silver & Gold Mines Ltd. (TSX VENTURE:ASM)(NYSE MKT:ASM)(GV6.F) ("Avino" or "the Company") today announced that it has now drifted along the San Gonzalo vein for over 200 metres to the northwest and 240 metres southeast of the main crosscut across from the ramp on level 5. The San Gonzalo Mine is located on the Avino property 80 km north east of Durango, Mexico.

  • Silver & gold grades increase
  • Continuity of vein improves

"We are very pleased with the grade and continuity of the vein on level 5. We look forward to processing this high grade material once it is mined. The San Gonzalo vein continues to improve as we get deeper; we are excited to see if this trend continues as we move on to level 6 and beyond."

- David Wolfin, President, CEO & Director, Avino Silver & Gold Mines Ltd.

Avino has taken face samples to the North West and to the South East along the vein. These samples are first assayed in Avino's own lab and provide a quick and inexpensive guide to vein width, grade and continuity. Before planning stopes between levels 4 and 5, Avino samples the back (roof) of the vein. These samples are then sent for independent analysis at Inspectorate Labs in Reno, Nevada.

Avino has received further sample results from Inspectorate labs as shown in the table below. These can be viewed on the level 5 sampling map on Avino's website: http://www.avino.com/i/pdf/SamplingMap-L5_SGMine.pdf. Some of the earlier sampled lengths have been recalculated and replace those shown in the Sept 16, 2013 news release. (assays have not changed). These are restated in the tables below together with the more recent assays as follows:

Sampling lengths along the vein are continuous as shown on the sample plan map available on Avino's website: http://www.avino.com/i/pdf/SamplingMap-L5_SGMine.pdf.

Individual samples that assayed above 1 kilogram silver per tonne are shown. These high values have been re-assayed by Inspectorate Labs. Values shown are averages.

In the July 2013 Technical Report on the Avino Property by Tetra Tech, assay values used to calculate the resource at San Gonzalo were plotted on histograms and capped at 6,000 g/t silver and 17 g/t gold. (Table 14.9 of report)

If in the future Avino recalculates the resource at San Gonzalo, high grade gold and silver values will be capped using new histograms, however, we prefer to put this material through our mill and sell the concentrate.

When the high grade material was first sampled on level 4 in April 2013, Avino commissioned a petro graphic report which identified native silver and gold electrum and high silver sulfo salts such as argentite. We are currently investigating modifying our current mill circuit to recover these separately from the concentrate. This could potentially allow us to produce doré bars on site as well as concentrate.

The San Gonzalo vein usually contains the highest gold and silver values but we drift wider along the vein and sample the country rock on both sides of the vein. The wall rocks usually contain metal values which decrease with distance from the SG vein. Thus we can plan mining over wider widths which provides more tonnage and wider stopes permitting easier operation using shrinkage methods yet still provides feed grade to our mill well above cut-off.

  Average Widths and Assay Values Over Total Length (221.23m) Sampled on Level 5
  Width (m) Gold (g/t) Silver (g/t) Pb % Zn %
Vein 1.67 7.39 663 0.64 1.05
Drift 2.60 2.77 438 0.43 0.71

Avino is very fortunate that at San Gonzalo we can mine wider than the actual vein without serious dilution of the grade.

Comparison of Vein Widths and Grade (Back Samples): 4th and 5th Levels
Width (m) Gold (g/t) Silver (g/t) Pb % Zn %
4th Level: 334.34m Sampled Length
1.72 2.05 440 0.64 1.16
5th Level: 221.23m Sampled Length
1.67 7.39 663 0.64 1.05

To date, drifting along the vein on level 5 has totaled 440 metres; however results from sampling have only been received for 221.23 metres. To accurately compare levels 4 and 5, sampling on level 5 must first be completed. Avino anticipates that vein length will improve on level 5 since the operation is now below the historic mine workings.

Assay Methods

Samples from level 5 underground channel sampling of the San Gonzalo vein are shipped to Inspectorate Labs for analysis for gold, silver, arsenic, bismuth, copper, molybdenum, lead, antimony, zinc, and mercury. Samples are crushed and ground in Durango with pulps assayed in Reno, Nevada using fire assay and AA finish for gold, four acid digestion and AA for most silver with fire assay and gravimetric finish for very high silver, and aqua regia digestion and ICP-MS for base metals. Inspectorate Labs in Nevada and British Columbia are ISO 9001:2008 certified, full service laboratories that are independent of Avino. Sample QA/QC procedures are as described in Section 11.5 of the July 2013 Technical Report on the Avino Property by Tetra Tech. 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 from level 5 sampling at San Gonzalo.

Cautionary Note to United States Investors - The information contained herein and incorporated by reference herein has been prepared in accordance with the requirements of Canadian securities laws, which differ from the requirements of United States securities laws. In particular, the term "resource" does not equate to the term "reserve". The Securities Exchange Commission's (the "SEC") disclosure standards normally do not permit the inclusion of information concerning "measured mineral resources", "indicated mineral resources" or "inferred mineral resources" or other descriptions of the amount of mineralization in mineral deposits that do not constitute "reserves" by SEC standards, unless such information is required to be disclosed by the law of the Company's jurisdiction of incorporation or of a jurisdiction in which its securities are traded. U.S. investors should also understand that "inferred mineral resources" have a great amount of uncertainty as to their existence and great uncertainty as to their economic and legal feasibility. Disclosure of "contained ounces" is permitted disclosure under Canadian regulations; however, the SEC normally only permits issuers to report mineralization that does not constitute "reserves" by SEC standards as in place tonnage and grade without reference to unit measures.
