Greenwich, CT -- November 30, 2006 -- Global Gold Corporation (OTCBB-GBGD) (www.globalgoldcorp.com) today announced positive test results from its wholly owned Tukhmanuk and Hankavan mining properties in Armenia. The Company recently completed the first phase of research to improve the recovery of metals within its processing plant at Tukhmanuk and to assess the feasibility of a quick start copper focused mining option at Hankavan. At Tukhmanuk, the results showed recovery can be improved to 80% and at Hankavan that copper recovery exceeded 80% and approached 90% in one instance.
At Tukhmanuk, mine production rates have recently been stepped up, at the same time confirmatory drilling has exceeded goals for 2006. The traditional method of gravity separation has demonstrated results of approximately 50.0 % recovery when processing sulfide ore. The production zone of the mine is now transitioning from oxide to sulfide ore. To develop the processing plant for the future sulfide ore supply, the recently concluded research establishes the base line for improving recovery and concentrate grade at the mine.
Research has been directed toward standard bulk sulfide flotation of the ore to separate the sulfide minerals containing the precious metals from the gangue minerals in order to maximize recovery. Additional research is being directed toward maintaining maximum recovery of metals while improving the commercial grade of the concentrate.
The flotation test results, conducted on the current ore being stockpiled ahead of the processing plant, have demonstrated, with a bulk sulfide flotation technique, that a recovery of gold in excess of 80.0 % can be achieved. Test results are noted below:
Ore Contents: | Total Concentrate Bulk Sulfide Flotation Recovery: |
---|---|
Gold-------5.1 g/dmt | 86.91 to 89.31 % |
Silver-----49.5 g/dmt | 70.00 to 71.83 % |
Copper----0.05 % | 94.03 to 94.18 % |
Zinc-------0.36 % | 73.92 to 86.11 % |
Lead-------0.30 % | 98.53 to 98.97 % |
Global Gold also recently concluded research on its Hankavan Property to evaluate the potential of implementing a "Fast Start" business model which focuses upon the hydrometallurgical processing of the oxide ore zone to recover soluble copper with standard copper leaching technology. The drill core from the company's recent drill program on the oxide zone was subjected to a bottle-roll test in a sulfuric acid solution at ambient pressure and temperature where the pH of the solution was maintained at a constant level. Tests were conducted for varying periods up to 120 hours where the copper mineralization demonstrated high solubility at extended periods where recovery of copper exceeded 80.0 % and approached 90.0 % in one instance. With these encouraging results, the company plans to conduct an expanded drill program that will define the oxide zone and generate drill core for additional metallurgical testing. Additional metallurgical testing is required to confirm this initial research and to provide data required for design of the hydrometallurgical processing facility to recover copper.
