Arizona Gold & Silver Inc. (TSX–V: AZS) (OTCQB:AZASF) is pleased to announce 90% to +99% gold extractions from agitation cyanide leach tests on two bulk samples from the Philadelphia Gold-Silver Property, Arizona. The results demonstrate the ready amenability of the feed material for cyanide gold extraction.

Initial agitation leach tests were performed by McClelland Laboratories in Sparks, Nevada on two bulk samples of material. The objective was to assess the amenability of the material to conventional milling and cyanidation leaching. The leach tests demonstrated gold recoveries of 90.6% to greater than 99.3% for all milled feed sizes. Leach kinetics were faster at the finer feed sizes and ultimate gold recoveries were greatest at the finer feed sizes. Cyanide and lime consumption was low in all tests. Lime addition averaged 1 kilogram per tonne.  Cyanide consumption averaged less than 0.1 kilogram per tonne.

Mr. Greg Hahn, VP Exploration commented, “These excellent results demonstrate the ready amenability of the feed material to milling/cyanidation treatment at different feed sizes, and the potential for heap leaching. They represent an important milestone for the Project.”

Agitation Leach Test Results

A total of four agitation leach (bottle roll) tests each were conducted from the two bulk samples at feed sizes ranging from 80% passing -425 microns, -212 microns, -150 microns, and -106 microns. The milling tests on these samples were performed at a cyanide concentration of 1.0 gram per liter for a leach cycle of 120 hours. Additionally, samples at -1.7mm feed size were performed at varying cyanide concentrations for a 72-hour leach cycle to assess the sensitivity of gold extraction to cyanide strength for consideration of heap leach test work.

Agitation leach tests on -1.7mm for a 72-hour cycle demonstrated gold recoveries of 72.7% to 73.6% at a cyanide strength of 1.0 gram per liter. These tests provide an indication of potential ultimate gold leach extractions under heap leach conditions.  Gold recoveries were lower at lower cyanide solution strength providing guidance that column leach tests be performed at a cyanide strength of 1.0 grams per liter.  Column tests on both bulk samples are currently under leach at feed sizes of 80% -6.3mm (-1/4 inch) and larger to quantify the amenability of the material to heap leaching. As of the date of this press release the columns have been under leach for +92 days and demonstrate a nearly linear recovery curve, with the -6.3mm (-1/4 inch) charge leaching faster than the -9.5mm (-3/8 inch) charge which is leaching faster than the -12.5mm (-1/2 inch) charge.  All test work to date indicates that gold recoveries and rates of extraction are sensitive to feed size, with gold recoveries increasing with decreasing feed/grind size.

These columns tests will continue until at least 120-days leach cycle or until gold extraction decrease materially.
