Global Gold Reports Positive Test Results
From Both Tukhmanuk and Hankavan Properties in Armenia
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.
Tukhmanuk Results
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 % |
Hankavan Fast Start Option for Copper Resul ts
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.
