Avino Updates At San Gonzalo Mine
VANCOUVER - Avino Silver and Gold Mines Ltd. reported activities at its San Gonzalo Mine 80 km North East of Durango, Mexico. Underground mining development is ongoing. The decline from level 4 to level 5 has advanced 170 metres to date, and a total of 200 metres remain until the level 5 elevation of 2130 metres is reached. The 4th level at 2175 metres elevation connects with the bottom of the old San Gonzalo workings. The level has intersected the bottom of the main shaft from the original mining which ceased with the revolution in the early 20th century.
Avino has been drifting (mining) along the San Gonzalo vein on the 4th level. Currently we have explored 150 m to the north west of the old shaft and 170 m to the South East. To view a map of the progress with assay results.
The 4th level is the last level where old workings had removed some of the deposit. The 5th level which we expect to reach before year-end will be all new development.
Drifting along the San Gonzalo vein on level 4 South East is ongoing. Avino staff channel sample the face after each round. These samples are analyzed for silver, gold, copper, lead and zinc by fire assay and AA methods at the company's own lab at the mine, providing a quick estimate of vein width, and grade.
Many of the samples taken produced silver assays results greater than 1,000 g/t confirming earlier drill results which indicated the deposit is significantly higher grade at depth , than at level 2 where the 10,000 tonne bulk sample test was drawn from in 2010.
Avino's president, Mr. David Wolfin said, We are very pleased to see the grades improving substantially as we get deeper into the mine as we expected. This, along with significantly better recoveries that were independently verified from the lower levels of the mine should significantly improve our production output in the coming months and years
The vein on level 4 North West of the old shaft has increased in width to 3 metres. Avino will be able to use the Cut & Fill mining technique allowing Avino to develop mill feed faster and more cost effectively than Shrinkage Stopping.
Total stockpile tonnage from San Gonzalo to date is 22,688 tonnes and consists of development and mineralized material from levels 2, 3 and 4 and the draw down from stope 3-200.
The company's address is 900, 570 Granville St., Vancouver, BC V6C 3P1.
