Vancouver, B.C. - Bear Creek Mining (TSX Venture: BCM) ("Bear Creek" or the "Company") is pleased to announce results for 27 additional diamond drill holes (4,643 meters). Drilling at Santa Ana now totals 45,946 meters in 251 drill holes. Santa Ana is located in southeastern Peru 200 kilometers south of the Company's Corani silver-base metal deposit which is currently advancing under pre-feasibility studies. Highlights of this press release include:
Andrew Swarthout, President and CEO of Bear Creek, states "We are extremely pleased that recent drilling results verify higher-grade, leachable silver mineralization occurs in at least two zones with excellent continuity, which have the potential to provide the basis for robust starter pits. These higher grade zones with large tonnages developing in the 90 g/t silver range provide confidence that Santa Ana can become as important economically to Bear Creek as our Corani silver-base metal deposit which is currently in pre-feasibility stage." Mr. Swarthout continues "Exploration upside also remains an exciting opportunity at Santa Ana as the deposit remains open. For instance, many of these latest higher grade zones were discovered beneath surface expressions with little evidence of the existence of silver mineralization; supporting our thesis that additional hidden or "blind" discoveries will continue to be made. In addition, two of the better holes (SA-138 and SA-139) are located well beyond the current resource boundary also indicating significant remaining growth potential throughout the still under-explored district." One-hundred-fifty-six drill holes have been now been completed since the first resource estimate in January 2008. "We are very excited to be able to soon see the effects of this recent drilling on the resources, both in size and grade, as we prepare for updating the model in September." New drilling results are as follow. All intercepts are down-hole lengths and true widths have not been calculated.
(Full drill results can be found at www.bearcreekmining.com. To access the silver drill hole map directly please refer to http://www.bearcreekmining.com/i/pdf/072108map.pdf Close-spaced drilling on 25 x 50 m centers has been completed on eight lines spaced throughout the mineralized area. An additional four detailed lines are planned and will be drilled over the coming weeks. New holes in this report, including SA-124, SA-133, SA-135 and SA-138 located on three separate lines, demonstrate that drilling on 25 x 50-meter centers will continue to:
Another extension of a significant structural corridor to the southwest of the current resource was intersected in hole SA-139 with intervals of 22 m @ 242 g/t Ag, 14 m @ 183 g/t Ag and 6 m @ 284 g/t Ag. The drill hole extends the mineralization 300 meters southwest of the first resource estimate, and mineralization remains open. Three drills continue on the property completing close-spaced infill and deposit extension drilling. Currently, two drills are focusing on confirming and expanding higher-grade silver zones with the objective of defining plus 90 g/t silver bodies. The third drill is following new extensions, such as the one discovered by drill holes SA-139 and SA-138. Metallurgy-ongoing leach testing continues to support high recoveries in heap leach conditions in all areas explored to date and across all silver grade ranges. As reported, column leach testing performed at McClelland Laboratories indicates that greater than 70% silver recoveries can be expected in a heap leach (see news release dated Feb 25, 2008). Continuous agitation bottle roll testing being performed at RDI's testing facilities in Denver, Colorado indicate similar leaching characteristics to the columns throughout the deposits. Additional column testing will be performed in the pre-feasibility stages of the project to further confirm recoveries. A second resource estimate is planned for release in September and will include approximately 156 additional drill holes, over double the number used in the first resource estimate of January 2008.
