AbraSilver Resource Corp. reported positive preliminary metallurgical test results for the new JAC zone at its wholly-owned Diablillos property in Salta Province, Argentina. The program was completed by independent metallurgical consultants, SGS Canada Inc., at their testing facilities in Lakefield, Ontario.

Key Highlights Include: Overall recoveries at the JAC and Fantasma deposits range between 86% - 93% for silver and 82% - 91% for gold. A substantial percentage of the silver at JAC can be recovered by gravity separation which increases overall recoveries. Current testwork confirms that the same process flowsheet can be used to process mineralization from the Oculto, JAC and Fantasma deposits.

Milling tests have shown that 150 microns is the targeted grind size for the leaching of the mineralized material at a retention time of 36 hours. Overall silver and gold recoveries could likely be increased further by grinding finer and with higher cyanide concentrations. Further metallurgical testwork and trade-off studies are now underway.

F favorable Recovery Rates vs. Prior Testwork. At the JAC and Fant plasma deposits the silver minerals (chlorargyrite and iodargyrite) are easier to release by grinding, and are more sensitive to cyanide leaching as they occur in argillic alteration, whereas at Oculto they are mostly held more complexly in vuggy silica host rock.

Testwork on JAC and Fantasma samples showed that gravity separation before cyanide leaching recovers approximately 9% of the silver and 17% of the gold which, when combined with the subsequent cyanide leaching recoveries, results in total overall recoveries of between 86% and 93% for silver and between 82% and 91% for gold. The median silver recovery of 89.5% relative to 73.5% for Oculto is particularly relevant because the mineralization at the JAC and Fant Plasma deposits is predominantly silver. JAC drill core samples for metallurgical testing were selected to be volumetrically representative of the mineralised system, being from the various zones of mineralisation along strike and at depth, including high, medium and lower grades.

Care was taken not to mix alteration zones so that geo-metallurgical domains can be determined.
