Avino Silver & Gold Mines (TSX VENTURE:ASM)(OTCBB:ASGMF)(BERLIN:GV6)(FRANKFURT:GV6) has reported on progress from its bulk sampling program at the San Gonzalo mine northeast of Durango, Mexico.
As Avino reported in its October 13th news release, two raises were driven to connect the lower level 2 (2260m elevation) with the upper level 1 (2306m elevation). The assays from initial sampling in the eastern raise have now been retrieved.
Samples are from channels cut across the San Gonzalo 1 vein. The samples were assayed by Inspectorate Labs. Samples were crushed and ground in Durango with pulps assayed in Richmond BC 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, Aqua Regia digestion and ICP for base metals.
Avino's mine staff report that approximately 2000 tonnes of mineralized vein rock have been broken from stope 2-140 so far, which is calculated to grade 1.9g/t gold and 340 g/t silver.
This compares well with the originally inferred resource (Orequest August 31, 2009 43101 compliant report) which estimated 444,250 tonnes at San Gonzalo grading 2.61 g/t gold, 322 g/t silver, 1% lead and 1.5% zinc.
Avino's mill has now completed processing the stockpiled copper ore from the original mining operation on the ET zone and will now undergo a two week maintenance upgrade prior to starting milling of the San Gonzalo material.
