Press Release: Avino Reaches Operational Milestone
Avino Silver and Gold Mines Ltd is pleased to announce that it has entered into an agreement with MRI Trading AG for the sale of all the copper concentrates produced from stockpiled material that remains on-site from previous mining. This material is currently being used to commission the refurbished 250tpd mill circuit in preparation for the treatment of the 10,000 tonne bulk sample from the underground development at San Gonzalo slated for later this year.
The terms of the agreement are to deliver 400 to 600 tonnes of concentrate containing approximately 50 to 70 tonnes of copper, 20,000 to 30,000 ounces of silver and 150 to 200 ounces of gold. To date six truckloads weighing over 200 tonnes have been delivered to the TMC warehouse at the Port of Manzanillo.
The sale of this concentrate will add to Avino’s cash position and help offset a portion of the on-going monthly operational costs.
In the month of July, the process plant treated approximately 4600 tonnes of ore for the production of 18 tonnes of copper, 8005 ounces silver and about 50 ounces of gold. These are plant operating figures and are subject to reconciliation once the concentrate shipment weights and assays have been finalized.
Underground development in July at San Gonzalo consisted of a total of 108 metres in both the 2306 and 2260 levels with the removal of 980 tonnes of development ore for future testing.
Founded in 1968, Avino has established a long record of mining and exploration in Mexico. The Company’s focus is to bring the property to production. Avino remains well funded.

Avino Press Release: Further Developments At San Gonzalo
Avino Silver and Gold Mines (”Avino”) is pleased to announce results of further underground development at its San Gonzalo project at the Avino property in Durango Mexico.
Avino’s mine contractor DMG have been driving two declines, the upper level 1 (2306 m) elevation and the lower level 2 (2260 m elevation). Both levels have intersected the San Gonzalo vein, Level 2 has intersected the San Gonzalo vein and a splay vein. These are known as San Gonzalo vein 1 and San Gonzalo. They are shown on a plan map on Avino’s website.
Avino’s previous news release June 4, 2010 gave results of channel sampling on lines 1 through 15 on the initial drifting (Level 2 2260m) along Veta San Gonzalo 1 (24.73 m length 2.15 m average width, 1.27 g/t gold, 341 g/t silver, 5274 ppm lead, 2273 ppm zinc, 442 ppm copper).
This heading was extended to a further 22 m to S.E. along the San Gonzalo 1 vein. Line 16 was not on the vein but Lines 17 through Line 21 gave assay results across the vein as follows:-
Line Width Au Ag Pb Zn Cu (m) (g/tonne) 17 1.50 1.874 886 5919 3827 1070 18 1.90 1.526 896 6272 6091 1057 19 1.70 1.621 32 21825 33562 1340 20 2.20 0.828 363 4907 4367 754 21 0.75 5.091 534 12000 10800 7160 Avg: 1.61 1.752 532 9651 11438 1605
Level 2 (2260 m) also explored San Gonzalo Vein (see plan map on Avino website). This vein is narrower but there are values in both footwall and hanging wall. Values have therefore been averaged across a minimum mining width of 1.2 metres as shown over a strike length of 28.45 metres.

The Upper Level 1 (2306 m) has been driven Northwest along the San Gonzalo Vein and has broken in to the old San Gonzalo workings.
The San Gonzalo vein in this location is narrow. Channel Samples L1 through L14 were collected across the vein along a strike length of 16.88 m. Over this length the vein averaged 0.73 m wide, 0.562 Gold, 108 Silver, 992 Lead, 2653 Zinc, 487 Copper (all values ppm).
The exploration drift on the Lower Level 2 (2260 m) along the San Gonzalo 1 vein is currently also being advanced to the northwest towards a possible intersection with the San Gonzalo vein.
All samples were assayed at SGS Labs Durango. The assay method for gold is FAA 313 which is gold by fire assay withAAS finish, For silver, the method is AAS 21E which is a 3 acid digestion followed by AAS finish. For silver assays greater than 300g/t, the FAG 313 is applied which is fire assay followed by a gravimetric finish. ICP 14B is used for lead, zinc and copper. This is an aqua regia digestion followed by ICP-AES finish. For assays greater than 10,000ppm, ICP 90Q is used which is the ore grade version using a sodium peroxide fusion followed by ICP-AES finish.
