Vancouver, British Columbia, May 23,2024 – TheNewswire – Arizona Gold& Silver Inc. (TSXV: AZS ) ( OTCQB:AZASF ) is pleasedto announce 90% to +99% gold extractions from agitation cyanide leachtests on two bulk samples from the Philadelphia Gold-Silver Property,Arizona. The results demonstrate the ready amenability of the feedmaterial for cyanide gold extraction.
Initial agitation leach tests were performed byMcClelland Laboratories in Sparks, Nevada on two bulk samples ofmaterial. The objective was to assess the amenability of the materialto conventional milling and cyanidation leaching. The leach testsdemonstrated gold recoveries of 90.6% to greater than 99.3% for allmilled feed sizes. Leach kinetics were faster at the finer feed sizesand ultimate gold recoveries were greatest at the finer feed sizes.Cyanide and lime consumption was low in all tests. Lime additionaveraged 1 kilogram per tonne. Cyanide consumption averaged lessthan 0.1 kilogram per tonne.
Mr. Greg Hahn, VP Exploration commented, “These excellent results demonstrate theready amenability of the feed material to milling/cyanidationtreatment at different feed sizes, and the potential for heapleaching. They represent an important milestone for theProject.”
Agitation Leach Test Results
A total of four agitation leach (bottle roll) testseach were conducted from the two bulk samples at feed sizes rangingfrom 80% passing -425 microns, -212 microns, -150 microns, and -106microns. The milling tests on these samples were performed at acyanide concentration of 1.0 gram per liter for a leach cycle of 120hours. Additionally, samples at -1.7mm feed size were performed atvarying cyanide concentrations for a 72-hour leach cycle to assess thesensitivity of gold extraction to cyanide strength for considerationof heap leach test work.
Agitation leach tests on -1.7mm for a 72-hour cycledemonstrated gold recoveries of 72.7% to 73.6% at a cyanide strengthof 1.0 gram per liter. These tests provide an indication of potentialultimate gold leach extractions under heap leach conditions. Goldrecoveries were lower at lower cyanide solution strength providingguidance that column leach tests be performed at a cyanide strength of1.0 grams per liter. Column tests on both bulk samples are currentlyunder leach at feed sizes of 80% -6.3mm (-1/4 inch) and larger toquantify the amenability of the material to heap leaching. As of thedate of this press release the columns have been under leach for +92days and demonstrate a nearly linear recovery curve, with the -6.3mm(-1/4 inch) charge leaching faster than the -9.5mm (-3/8 inch) chargewhich is leaching faster than the -12.5mm (-1/2 inch) charge. Alltest work to date indicates that gold recoveries and rates ofextraction are sensitive to feed size, with gold recoveries increasingwith decreasing feed/grind size.
These columns tests will continue until at least120-days leach cycle or until gold extraction decreasematerially.
