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.

"We are very pleased with the results of this study. We've substantially increased the resource at San Gonzalo and have the first ever mineral resource estimate on the main Avino Mine. The Avino property has an extensive mining history; with this new resource estimate and our improving exploration capabilities, Avino is poised to continue that legacy into the foreseeable future"

David Wolfin, President, CEO and director of Avino Silver and Gold

Highlights of the San Gonzalo Mine Resource include:

-- A measured and indicated silver resource of 293,823 tonnes at an average grade of 297 g/t silver and 1.98 g/t gold totaling 2,803,315 troy ounces of silver and 18,551 troy ounces of gold using a base case cut-off grade of 150 g/t silver equivalent.-- An inferred silver resource of 1,085,276 tonnes at an average grade of 233.8 g/t silver and 1.42 g/t gold totaling 8,158,834 troy ounces of silver and 49,549 troy ounces of gold using a base case cut-off grade of 150 g/t for silver equivalent.



Highlights of the Avino Mine Resource include:

-- An indicated silver resource of 4,253,968 tonnes at an average grade of 79.2 g/t silver, 0.528 g/t gold and 0.727% copper totaling 10,835,338 troy ounces of silver, 72,207 troy ounces of gold and 30,914 tonnes copper using a base case cut-off grade of 100 g/t silver equivalent.-- An inferred silver resource of 3,220,896 tonnes at an average grade of 68.3 g/t silver, 0.733 g/t gold and 0.55% copper totaling 7,068,831 troy ounces of silver, 75,858 troy ounces of gold and 17,719 tonnes of copper using a base case cut-off grade of 100 g/t silver equivalent.



San Gonzalo Mine System:

The San Gonzalo Mine estimate was based on data from surface diamond drill programs between 2007 and 2011 (64 holes and 14,624 metres of drilling) and underground development sampling data from levels 1, 2, 3 and 4. Modelling of this data also shows the presence of mineralization for the nearby Angelica vein and its resource estimate has been added to those of the San Gonzalo vein.

The base case scenario used in the estimation assumes a silver price of $US20 which translates into a cut-off grade of 150 g/t silver equivalent at San Gonzalo. The current silver price analysis using US$24.50 per ounce establishes a cut-off grade of 120 g/t for silver equivalent. Since commercial production began in October 2012, Avino has been using a cut-off grade of 120 g/t for silver equivalent.

Avino Mine System:

The Avino Mine estimate was based on data from surface diamond drill programs between 2006 and 2012 (34 holes and 11,523 metres of drilling). Historic mining information was also provided to assist with the modelling of the deposit for the mined out open pit and underground areas as well as to project the shape of the deposit below the 12th level. The 3D wire frame model shows the presence of another mineralization zone called the "Hanging Wall Breccia" or "Cross Cutting Vein". Its resource estimate has been included in the Avino Mine system.

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.

Method of Mineral Resource Calculation

The Avino system and San Gonzalo system mineral resources were modelled and estimated using Datamine™ software version 3.20.6140.0. The reported mineral resource was interpolated using ordinary kriging (OK) and capped grades. Avino mineralization included the interpolation of silver, gold and copper, while San Gonzalo mineralization included the interpolation of silver and gold. Where sufficient data was available, specific gravity (SG) was estimated using OK, otherwise the average estimated value was assigned.

Reported cut-offs utilize a silver equivalent (Ag_Eq) calculation where the total metal value is converted into an in situ silver resource. For reporting purposes, a base-case Ag_Eq cut-off of 100 g/t is used for the Avino system and an Ag_Eq cut-off of 150 g/t is used for the San Gonzalo system. Current cut-offs used for financial projections by Avino, based on recent market prices, include 80 g/t for the Avino system and 120 g/t for the San Gonzalo system.

To calculate the above silver equivalent grades, Avino has assumed a price of silver of US $20 per oz., a price of copper of US $3.66 per lb. with a recovery rate of 85% for copper, and a price of gold of US $1,507 per oz., with 75% recovery rate for gold at the Avino Mine and 70% recovery rate for gold at the San Gonzalo Mine.

The oxide tailings mineral resource was estimated using Geovariance Isatis™ software and OK interpolation with uncapped grades. The assay values for this estimate are based on 28 drill holes which were completed on the tailings by CMMA in 1990, and include 407.75 m of drilling and 383 assays of both gold and silver. A specific gravity of 1.605 was used based on the global average for the oxide tailings reported by Slim (2005d). For reporting purposes, a silver cut-off of 50 g/t was used; an Ag Eq value was not calculated for the oxide tailings. This mineral resource was estimated by Mr. Mike O'Brien, and has an effective date of July 24, 2012. It was originally disclosed by Tetra Tech (2012), but is considered current.

Improving Exploration Abilities

Avino recently purchased Gemcom 3D software and plans to import the new digital database compiled by Tetra Tech during the resource calculation process. This new software will allow Avino's 4 geologists to compile significant raw data---including 80 Kilometres of IP (Induced Polarization) Geophysics, 1,500 soil samples, topography, drill hole data and satellite imagery collected between 2006 and 2008 before the Company's priority shifted to San Gonzalo Mine development and mill refurbishment. Using this technology, management anticipates finding new significant drill targets. The Company owns two drill rigs (one surface and one underground) and has the capability to drill these new targets as well as existing targets once the 3D model is completed.

Technical Report Filing

Avino will file the Tetra Tech NI 43-101 Technical Report from which the above resource numbers were derived, onto the SEDAR website upon receipt within the next 45 days.

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.
