To all from GPGI web page: AuRIC REPORTS ON DORE BAR REFINING PROGRESS In February, approximately 1,700 pounds of dore bars were delivered to AuRIC Metallurgical Laboratories for electro-winning into sludge and subsequent refining. It was anticipated that AuRIC would have the final results from the refining process before now. At a meeting, in Salt Lake City with Global's technical consultant Mr. Russell Twiford, AuRIC stated that the inordinate delay in the processing of the dore bars was brought about by the fact that of the 1,700 pounds, consisting of more than 75 separate bars, lacked consistency between the dore bars. AuRIC further explained that their procedures require the adjustment of temperature, DC current and chemical concentrations to suit the particular composition of the dore bar and the wide variance between bars made the entire process very slow and inefficient. It was also explained that the very large concentration of copper in the bars contributed to copper contamination of the sludge, which interfered with and made the final refining process very difficult. Mr. Twiford agrees with AuRIC, while pointing out that the variance in the bars was a result of the utilization of several differing experimental processes targeted at determining the ideal method of production. Mr. Twiford, however, does understand the difficulty this has caused AuRIC and Mr. Twiford agrees a more consistent product is required for an efficient refining process. Mr. Ahmet Altinay, AuRIC's manager and metallurgical engineer, has made several useful suggestions to Global calculated to improve the production and refining processes. AuRIC and Global continue their good relationship and move forward from this point. AuRIC has agreed to assist Global in accomplishing the end goal of producing a precious metal dore bar which is compatible with conventional refining methodology. AuRIC continues to work on the refining of the 1,700 pounds of dore bars and shall report final results when those results are available. END
