News a little dated but not posted anywhere. NANECO MINERALS LTD. ("NNE-Y") - Metallurgical Tests at Jiawula Indicate Zinc & Lead Recoveries - of 91.9% and 93.3% and 84.5% Total Recovery of Silver Process Research Associates Ltd., of Vancouver, B.C., Canada, has completed a preliminary flotation test program on samples from the Naneco Minerals Ltd. (Alberta Stock Exchange - Symbol NNE ) Silver-Zinc-Lead-Copper Zone No. 2 deposit located at Jiawula, Nei Mongolia, China. Results of this test program show substantial improvements in recovery of all metals, when compared to results obtained after similar earlier work by others. Evaluation of the PRA test data suggests that further improvements in recovery will be achieved after planned additional testing is completed which will be oriented to optimizing the flotation parameters and flowsheet used. The representative head sample obtained from drill reject pulp samples, used for flotation feed assayed 137.00 g/mt Ag, 3.72% Pb and 7.7% Zn. Recoveries for Pb plus associated Ag concentrate and Zn plus associated Ag concentrate were as follows: Pb + Ag Zn + Ag Total Recovery (%) 93.3% + 66.2% of Ag 91.9% + 18.3% of Ag 84.5% Pb and Zn recoveries were 93.3% and 91.9%, respectively. Approximately 66.2% of the Ag reported to the Pb concentrate and 18.3% reported to the Zn concentrate, for a total recovery of 84.5%. Further comprehensive metallurgical tests will now be conducted on bulk samples obtained from the deposit for final flowsheet design. TEL: (403) 232-6833 Archie J.
