TORONTO, Oct. 18, 2012 /CNW/ - Atlanta Gold Inc. (TSXV: ATG; OTCQX: ATLDF) announces positive metallurgical results from the 107-ton bulk sample extracted from exploration trenches at its Atlanta gold project in Elmore County, Idaho.
As previously announced on July 5th and August 12th, the Company processed the initial bulk sample at Knife River Corporation's test facility in Boise, Idaho. This test facility is meant to model their process plant operating in Idaho City which is effectively a giant sluice box that washes away lighter crushed rock from the gold particles. It uses no chemicals, is cost effective and is described in more detail in a September 15th local news article that can be viewed at: http://www.idahostatesman.com/2012/09/15/2272575/gold-mining-with-a-green-twist.html#storylink=misearch.
"These initial metallurgical test results confirm that the processing method successfully liberates the gold content present in the extracted material. We plan to work with Knife River to replicate the existing process facility on the Atlanta project site, improve the technology and customize it for Atlanta's purposes. Apart from the significant environmental benefits such as no use of chemicals, the recycling of water and the capturing of heavy metals, the capital and operating costs for this type of facility are expected to be much less than those for a conventional mill", said Ernie Simmons, President and CEO of the Company.
The 107-ton bulk sample was crushed down to a feed size of 1/8" which was processed in two days through the gravity-washed system, and samples were assayed at four collection points in the system (feed, sluice carpet, underjig and tailings). Free gold particles collected in the system would be sent for refining into doré gold bars; while the remaining sulphide material, commonly referred to as black sand will be further processed offsite.

The results indicate that processing of the initial bulk sample left significant amounts of gold behind in the tailings. Further test work is obviously necessary to improve recovery. Therefore, the Company will reduce the grind size of material to a feed size of +50 (+10 mm) mesh, relocate the jigs and reduce the angle of the sluice boxes so that less than 0.001 opt (0.034 gpt) Au remains in the tailings. A small test sample has been successfully processed subsequent to the 107-ton bulk sample, and demonstrates the potential of this refinement. It is anticipated that an ongoing program will be necessary to customize the process for the material extracted from the exploration trenches, and to optimize recoveries.
The Company had previously anticipated that the 107-ton bulk sample would yield a gold and silver concentrate weighing less than 1,000 pounds (news release of August 1, 2012). By implementing the above processing changes, the Company expects to meet its recovery and concentrate grade objectives.

Such are based upon assumptions, estimates, opinions and analysis made by management in light of its experience, current conditions and its expectations of future developments as well as other factors which it believes to be reasonable and relevant. These assumptions include those concerning the successful and timely completion of sufficient additional financings by the Company and/or Atlanta Gold Corporation ("AGC"); the availability of requisite equipment and manpower; the ability to achieve cost estimates; and general business and economic conditions.
