Avino Announces an Updated Mineral Resource Estimate at the Avino Property

Avino Silver & Gold Mines Ltd. (ASM: TSX/NYSE American, GV6: FSE, “Avino” or “the Company”) is pleased to announce the completion of an updated mineral resource estimate for the Company’s Avino Property located near Durango in west-central Mexico (the “Property”). The updated estimate encompasses the Property’s San Gonzalo Mine, the Avino Mine vein systems, and the Property’s Oxide Tailings. The mineral resources estimate has been included in an updated technical report prepared by Aranz Geo Ltd. under National Instrument 43-101 (“NI-43-101”), which will be available on SEDAR (www.sedar.com) under the Company’s profile and filed on Form 6-K with the SEC within 45 days.

This updated mineral resource estimate includes 34 drill holes that were completed during the drill programs from 2016 to 2017. These drilling programs have significantly increased the amount of information available for resource estimation. The drill holes and assay data were incorporated into the updated mineral resource estimate.  The results of the additional drilling contributed to an approximate 225% increase in tonnage in the Measured and Indicated Resource categories and a decrease of 25% in the Inferred resource due to a conversion of a portion of the Inferred Resources to the Indicated Resource category.

The total measured and indicated mineral resources in all deposits totals 10.7 million metric tonnes containing 47.5 million troy ounces of silver equivalent, 26.3 million troy ounces of silver, 217 thousand troy ounces of gold, and 86 million pounds of copper. The total inferred mineral resources in all deposits totals 6,090,000 metric tonnes containing 23.2 million troy ounces of silver equivalent, 13.6 million troy ounces of silver, 109 thousand troy ounces of gold, and 33 million pounds of copper.

“We are very pleased with the updated mineral resource estimate, which demonstrates a significant increase in the mineral resources potentially available for mill feed” said Avino President and CEO, David Wolfin. “The successful drill program that started in 2016 has allowed us to evaluate the tonnage and grade in the area between the San Luis workings and the ET production area, the results of which have now been incorporated into this updated mineral resource estimate. We are confident that our 2018 exploration program will continue to build on the success of our past operations. I would like to thank the exploration team in Mexico for their continued and invaluable efforts. Avino is celebrating its 50th year in the mining industry, and this would not be possible without the hard work and dedication of the entire Avino team.”

The following is a summary of current resources at the San Gonzalo and Avino Mines, as well as the updated oxide tailings resource, grouped into the measured, indicated and inferred categories. The effective date of the resource estimates is February 21, 2018.

The resource estimates were prepared by Michael O’Brien P.Geo., Pr.Sci.Nat., who is a “Qualified Person” within the meaning of NI 43-101 and who is an employee of ARANZ Geo and independent of Avino, as defined by Section 1.5 of NI 43-101.

Mineral resources which are not mineral reserves do not have demonstrated economic viability. The estimate of mineral resources may be materially affected by environmental, permitting, legal, title, taxation, sociopolitical, marketing, or other relevant issues. The quantity and grade of reported Inferred resources in this estimation are uncertain in nature and there has been insufficient exploration to define these Inferred resources as an Indicated or Measured mineral resource and it is uncertain if further exploration will result in upgrading them to the Indicated or Measured mineral resource category.

Figures in the table may not add to the totals shown due to rounding.

The mineral resource estimate is classified in accordance with the Canadian Institute of Mining, Metallurgy and Petroleum’s “CIM Definition Standards- for Mineral Resources and Mineral Reserves” incorporated by reference into National Instrument 43-101 “Standards of Disclosure for Mineral Projects”.

Mineral Resources are reported at cut-off grades 60, 130 and 50 g/t silver equivalent grade for the Avino, San Gonzalo and oxide tailings respectively as indicated in the table.

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.

The silver equivalent was calculated using the following assumptions:

For Avino (ET and San Luis), San Gonzalo and Oxide Tailings

Au price US$1,300/oz
Ag price US$ 17.50/oz
Copper price US$3/lb
A net smelter return (NSR) was calculated and the silver equivalent was back calculated.

For ET using the formula:
AgEQ = (24.06 x Au (g/t) + 0.347 x Ag (g/t) + 43.0 x Cu (%) - 151.8 x Bi (%)) / 0.347

For San Gonzalo using the formula:
AgEQ = (0.03 x Au (g/t) + 0.385 x Ag (g/t) - 4.03 / 0.385

For Oxide Tailings using the formula:
AgEQ = 69.37 x Au (g/t) + Ag (g/t)

Highlights for each deposit include the following:

The Avino Mine

• A measured and indicated resource of 8,800,000 tonnes (at an average grade of 61 g/t silver, 0.61 g/t gold and 0.45% copper) containing 17.2 million troy ounces of silver, 172,500 troy ounces of gold and 39,000 tonnes copper using a cut-off grade of 60 g/t silver equivalent.
• An inferred resource of 4,160,000 tonnes (at an average grade of 57 g/t silver, 0.60 g/t gold and 0.35% copper) containing 7.7 million troy ounces of silver, 80 thousand troy ounces of gold and 15,000 tonnes of copper using a cut-off grade of 60 g/t silver equivalent.

The measured and indicated tonnage for the Avino Vein system at the ET Mine has increased from 1.45 million tonnes to 8.80 million tonnes due to infill drilling, increased width of the vein below 11th level, and additional hanging wall units encountered between San Luis and ET. The inferred tonnage has decreased by 28% from the previous estimate mainly due to in-fill drilling conversion to indicated resources.

The Avino Vein System at the ET Mine contains over three quarter of the tonnage on the Avino property and includes significant copper grades.

San Gonzalo Mine

• A measured and indicated resource of 530,000 tonnes (at an average grade of 288 g/t silver and 1.47 g/t gold) containing 4.9 million troy ounces of silver and 25,000  troy ounces of gold using a cut-off grade of 130 g/t silver equivalent.
• An inferred resource of 120,000 tonnes (at an average grade of 219 g/t silver and 0.86 g/t gold) containing  0.8 million troy ounces of silver and 3,300 troy ounces of gold using a cut-off grade of 130 g/t for silver equivalent. The decrease in Inferred resource is mainly due to development-based conversion of inferred resource to indicated resource.

The San Gonzalo Vein System is comparatively higher grade and provides flexibility to the Company’s mining production during times of uncertain metal prices.

Oxide Tailings

The oxide tailings estimate has not been modified since 2016 and no further sampling or modelling work has been carried out.

The indicated silver resource is unchanged and includes 1,330,000 tonnes at an average grade of 98 g/t silver and 0.46 g/t gold totaling 4.2 million troy ounces of silver and 19.8 thousand troy ounces of gold using a cutoff grade of 50 g/t silver equivalent.

The inferred resource is also unchanged and includes 1,810,000 tonnes at an average grade of 88 g/t silver and 0.44 g/t gold totaling 5.1 million troy ounces of silver and 25.6 thousand troy ounces of gold using a cut-off grade of 50 g/t for silver equivalent.

Method of Calculation

The estimation methods used were substantially the same for all three deposits, providing a consistent baseline for strategic planning.

Mineral resources were estimated by ordinary kriging, optimized using kriging neighborhood analysis and verified by means of nearest neighbor and inverse distance methods, swathplot comparisons of estimates and visual inspections. Block models were created for the San Gonzalo and Avino Vein Systems and the Oxide Tailings deposit and estimates were made utilizing blocks of sizes 20 m easting x 5 m northing x 10 m elevation for Avino (ET Mine), sizes 10 m easting x 5 m northing x10 m elevation for San Gonzalo and 40 m easting x 40 m northing x 2 m elevation for Oxide Tailings.

Classification of the mineral resource was based on ‘slope of regression’ as a measure of uncertainty, with adjustment to practical geometries using geological knowledge of the deposit. 

Fundamental changes since the previous mineral resource estimates are (1) depletion due to mining (over 800 thousand tonnes milled since the beginning of 2017), (2) significant new sampling information (3) changes to cut-off calculations and (4) reclassification of mineral resources in the light of improved understanding of confidence in the deposits at distances from the underground channel samples and drill hole samples.

More sampling information does not always lead to direct increases in resource tonnages and contained metal. In some cases, the new information provides improved understanding (developed by variogram modelling and kriging neighborhood analysis) that may demote some portions of mineral resource from high confidence categories, such as measured and indicated, to a lower confidence category such as inferred.

Currently, for the San Gonzalo and Avino Vein Systems, estimated blocks more than thirty metres from sampling are not considered to be of sufficient confidence to be included in the indicated category resources and have been classified as inferred resources.

For the Oxide Tailings, estimated blocks more than fifty metres from sampling are not considered to be sufficiently confident to be included in the indicated category resources.
