BEAR CREEK ANNOUNCES ADDITIONAL METALLURGICAL TEST RESULTS
Bear Creek Mining Corp. has learned that the preliminary cyanide bottle-roll leaching results for the oxide mineralization at the Corani project reported to the company by Plenge Laboratories in Lima, Peru, and detailed in its news issied in Stockwatch dated Nov. 14, 2005, contained assay errors. To confirm the earlier work performed by Plenge, samples were collected for shipment to Salt Lake City for testing at Dawson Metallurgical Laboratories. The initial Dawson testwork still shows that the material responds to leaching, but indicate that recoveries for oxide mineralization are on the order of 55 per cent to 70 per cent compared with the 75 per cent to 95 per cent in the preliminary report from Plenge. Testing at both labs is considered very preliminary. Further testing, including cyanide leaching and flotation, is continuing at Dawson to determine the appropriate metallurgical process for the Corani mineralization. The metallurgical work will progress concurrently with the resource calculation being performed by SRK Consulting.
According to Andrew Swarthout, president and chief executive officer: "While these preliminary bottle-roll leach tests are still considered positive for a silver deposit, they indicate lower recoveries than the initial testing. Further work is proceeding, including optimization of crush size and leach conditions, to quantify the economic benefits of low-cost leaching of the lower-grade material, which halos the higher-grade mineralization. We have always recognized that a significant amount of the value of the mineralization at Corani is derived from lead (and zinc), therefore, flotation and gravity separation tests are in progress to optimize recoveries of these byproducts and provide the best economic alternatives for maximizing the value of the deposit. The company remains very confident that a positive metallurgical flow sheet for the project will be developed."
Drilling is restarting this week following the Christmas break with three drills. Drilling will continue to explore extensions to the north and east on Corani Este, where the last drill holes intersected the thickest mineralization to date on the project. At Main Corani, one drill will continue to extend mineralization to the north and west where mineralization also remains open. Drilling will focus on step-out drilling along the recently drilled gold zone where the first three drill holes intersected three grams per tonne gold. A fourth drill will be added to explore new targets such as La Curva and trench 25, located west of Main Corani, where trenching results indicate that mineralization extends under cover. The next drill assay results are expected to be released in February.
