Golden Arrow Resources Corporation (TSX-V: GRG, FRA: GAC (WKN: A0B6XQ), "Golden Arrow" or the "Company") is pleased to announce the results of the preliminary bench-scale metallurgical test program on representative samples from the Chinchillas silver-zinc-lead project in Argentina. Conclusions from the metallurgical report include: "The samples responded very well to sulphide flotation, with silver recoveries averaging 98.7%, accompanied by very high lead and zinc recoveries."
"We are very pleased that this initial program indicates that we can expect excellent recoveries of silver and base metals using conventional flotation methods with standard reagents. These results, together with our upcoming resource estimate, will aid in evaluating the economics and viability of mineral production at Chinchillas." stated Brian McEwen, VP Exploration and Development.
Metallurgical Program
The test work was completed by Inspectorate Exploration & Mining Services Ltd. ("Inspectorate") of Richmond, B.C Canada under the direction of the Company's consulting metallurgist, Mr. John Fox. Three samples of approximately 50kg each were shipped to Inspectorate. The samples included representative composite samples of drill core from the Silver Mantos and Socavon del Diablo zones, as well as the mineralized basement, described in previous news releases as "Pirquitas-style".
Initially, a rougher flotation test was done at three different grind levels and sampled in four stages. The Chinchillas samples responded very well to flotation and were found not to be sensitive to grind size. Maximum rougher silver recoveries were 99.8, 97.0 and 99.3% in the Basement, Socavon and Silver Mantos composites, respectively. The lead recoveries were also very high, at between 96.5 and 98.1% for all rougher tests, while zinc recoveries were generally lower, between 66.0% and 96.1%. Following the rougher tests, cleaner flotation testing returned silver grades from 554 g/t in the zinc-rich Socavon composite to 11,268 g/t in the Silver Mantos composite, with silver recoveries for all three in the range of 89-92%.
Metallurgical test work will continue, in particular to optimize the flowsheet to produce a separate high-grade silver-bearing lead concentrate and a zinc concentrate.
