Marketwired Canada
Avino Silver & Gold Mines Ltd. ("Avino") (TSX
VENTURE:ASM)(OTCBB:ASGMF)(BERLIN:GV6)(FRANKFURT:GV6) 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:-

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.
