Atlanta Gold Announces Positive Results from Preliminary Metallurgical Testwork

TORONTO, June 26, 2013 /CNW/ - Atlanta Gold Inc. (TSXV: ATG; OTCQX: ATLDF) today announced positive metallurgical test results from 11 tons of bulk stock material previously washed by a sluice/jig plant located at the Knife River Corporation's facility in Boise, Idaho (see news release dated September 26, 2012) with the objective of obtaining 25 lbs of concentrate for refining evaluations and estimating costs.

The initial bulk sample of 107 tons processed by Knife River in August 2012 recovered 20% of the gold values from an average feed of 0.051 ounces per ton (opt) Au. Reprocessing in June 2013 of 11 tons of the materials remaining from the initial bulk sample and grinding to -20 mesh liberated additional gold and heavy metals produced a concentrate of 18.896 opt Au which was verified by an independent mine laboratory. Of the total gold, 66.6% was recovered from standard cyanidation. Using grind, roast and cyanidation, overall recovery rates increased to 88.9%.

Wm. Ernest Simmons, President & CEO commented: "Additional lab work will be needed to optimize grinding, roasting and cyanidation at a selected toll recovery facility located out of state. We are very pleased with this initial result which demonstrates that with some fine tuning on the gravity test we will be able to maximize the recovery of the metals from onsite concentrates that are of a quality that justify toll processing and refining costs."

The objective for Final Recovery testing is to determine if the onsite gravity recovery system would produce a concentrate using only water as a medium. This testing supports the hypothesis that gravity separation is a viable option.

Bulk stock material was fed by hopper conveyor feeder to a ball mill and the outflow slurry delivered to a custom sluicing system with an 8 foot long spreading flume and into a 30 inch wide by 4 foot long sluice box containing low profile riffles.

The sluice concentrates were collected after each 2,000 lb run. The concentrates were taken back to the shop, screened through a 20-mesh screen and the -20 mesh was upgraded/cleaned on a 4x8 shaker table, producing 25 lbs of heavy concentrate obtained from processing 11 tons of the feed material.

The +20 mesh, shaker table tails, -20 mesh sluice concentrate, head feed samples, sluice tailings and overflow slimes were saved, dried, sealed and sent for assay.

Notable amounts of fine, free gold was visible in the concentrate from approximately to -20 mesh down to the finest gold the human eye can detect.
