Scorpio Receives Metallurgical Test Work and Moves Forward Wednesday February 21, 8:00 am ET biz.yahoo.com TSX:SPM VANCOUVER, Feb. 21 /CNW/ - Scorpio Mining Corporation (TSX:SPM - News) is pleased to report metallurgical results from the SGS Lakefield's metallurgical lab, located in Lakefield, Ontario, on a sample of mineralized material from the Nuestra Senora Silver - Zinc deposit. The metallurgical testing of a mineralized bulk sample from the Nuestra Senora deposit has been completed by SGS Lakefield. The following is the executive summary from their report: "The sample graded 1.69% Cu, 1.35% Pb, 3.37% Zn and 172 g/t Ag. Mineralogical examinations indicated that sulphide minerals were coarse grained associations between the various distinct sulphide phases. Galena had finer grain structures and more complex associations than other sulphide phases. Notable amounts of secondary copper mineralization was present. A Bond ball mill work index test was completed on this ore and determined to be of average hardness at 12.7 kWh/t." "Batch flotation testing found that primary grinding to P80's in the range of 75 - 100 microns was acceptable. Galena required a regrind to approximately 80% passing 25 microns to improve concentrate grades. It was unclear whether a regrind was necessary for copper cleaning. Zinc regrinding was not warranted. Flowsheet development determined that similar metallurgy was achievable through bulk flotation of Cu-Pb followed by Cu/Pb separation by depression of Cu versus fully sequential Pb-Cu-Zn rougher flotation. This latter flowsheet required no additions of sodium cyanide in the process. Testing on the fully sequential flowsheet was pursued through confirmatory locked cycle testing. The following results were achieved in the best test and are presented in Table 1:" Table 1 - Grade and Distribution ------------------------------------------------------------------------- Product Wt Grade, %, g/t Distribution, % % Cu Pb Zn Ag Cu Pb Zn Ag ------------------------------------------------------------------------- Pb Conc 2.5 16.9 46.5 4.14 4893 26.5 92.3 3.2 70.4 Cu Conc 2.3 32.7 1.25 5.06 1203 47.2 2.3 3.6 16.0 Zn Conc 5.9 6.38 0.36 48.7 226 23.1 1.7 87.6 7.5 ------------------------------------------------------------------------- Final Tails 89.5 0.059 0.053 0.20 12.0 3.3 3.7 5.5 6.1 ------------------------------------------------------------------------- Head 100.0 1.59 1.26 3.23 172 100.0 100.0 100.0 100.0 ------------------------------------------------------------------------- ------------------------------------------------------------------------- "A Pb Concentrate grading 47% Pb, 17% Cu and 4900 g/t Ag recovered 92% lead and 70% silver while recovering 27% of the copper. A Cu Concentrate grading 33% Cu and 1200 g/t Ag recovered 47% of the copper and a further 16% of the silver. A Zn Concentrate graded 49% Zn while recovering 88% of the zinc. The Zn Concentrate contained about 6% Cu and the Cu Concentrate contained 5% Zn. It is felt that further testing may correct for the poor Cu-Zn selectivity." (Imeson, Dan.; Fleming C. A.; December 2006). Peter J. Hawley, Chairman, CEO reports, "The metallurgical test results are excellent and produced high-grade, clean copper, lead and zinc concentrates. The company's mill consultants, Genivar are conducting additional tests at SGS Lakefield with various depressing reagents to improve and upgrade the selectivity of the sulphides of both grades and recovery. The preliminary flowsheet has been designed and will be finalized once the studies are complete. The General Arrangements (GA's) for the excavation of the mill facility has been designed in advance as not to delay construction. The Company continues to accelerate both the underground mine planning, development and mill construction."
