Bear Creek Santa Ana Drilling Continues To Expand Silver Mineralization, Including High-Grade Additional Positive Metallurgical Results Reported
 Vancouver, B.C. - Bear Creek Mining (TSX Venture: BCM) ("Bear Creek" or the "Company") is pleased to announce results from sixteen additional diamond drill holes (3,775 meters). Drilling at Santa Ana now totals 16,577 meters in ninety-eight drill holes. Santa Ana is located 200 kilometers south of the Company's Corani silver-base metal deposit in southeastern Peru. Highlights of this press release include:

  • Drill hole SA-42A intersects 32m @ 203.7 g/t Ag, including 6m @ 884.7 g/t Ag

  • Drill hole SA-41A intersects 32m @ 64.8 g/t Ag, including 12m @ 123.7 g/t Ag

  • Drill hole SA-43 intersects 106m @ 30.8 g/t Ag, including 12m @ 88.5 g/t Ag and 1.2% Zn

  • Drill hole SA-45 intersects 100m @ 27.8 g/t Ag and 7m @ 372.2 g/t Ag (TD)

  • Drill hole SA-46 intersects 50m @ 85.4 g/t Ag, including 24m @ 133.9 g/t Ag

  • Drilling under thin soil cover continues to intersect mineralization, including higher-grade structures

  • Mineralized footprint now extends 1.8km by 850 meters and remains open in all directions.
Andrew Swarthout, President and CEO of Bear Creek, states "We continue to intersect strong mineralization as we step out into the open directions of this large silver system. Drill holes SA-42A and SA-46 validate the soil geochemical anomaly to the southwest and holes SA-43 and SA-45 show continued mineralization west under the post-mineral tuff. On the southeast, drill hole SA-41A, in conjunction with the previously reported SA-39, indicate mineralization along the untested eastern side of the range-front where colonial workings evidence potential mineralization for a distance of 400 meters. In addition, drilling is in progress 300 and 500 meters north of the northern-most, mineralized drill hole SA-30. The first resource calculation is being prepared but as in any emerging, significant discovery, this will likely be only an initial snap-shot as drilling is continuing to extend the footprint and the edges of the mineralization have not yet been defined. We are very pleased that the metallurgical testing is on track to be able to produce a scoping study of the project in the first quarter 2008."
Drilling results are as follow. All intercepts are down-hole lengths and true widths have not been calculated.

Drilling continues to intersect blind, high-grade structures within large halos of lower grade heap-leach material (SA-42A, SA-43 and SA-45). New soil and rock grid sampling data from areas with no outcrops has extended the mineralization 500m to the north and 100m to the west and these areas, as well as infill holes, will be followed up through grid drilling that is continuing with 2 rigs. Data is being assembled that will allow for a resource estimation anticipated in early 2008.

Santa Ana Metallurgy: The testing of three columns simulating heap leach conditions is scheduled to be completed on Nov 21st following 120 days of leaching, at which time the columns will be unloaded for screen-fraction analyses and assay of residuals. By early December, the final recoveries and reagent consumptions will be calculated, and an analysis of optimum crushing sizes for heap leach feed can be made for scoping and Preliminary Economic Assessment purposes. Recoveries on the order of 60% to 65% silver for average grade conventional crushed heap leaching method (3/4 inch crush) and at least 70% silver for the pulp agglomeration method are expected based on preliminary results.

Santa Ana Resource and Engineering: Independent Mining Consultants, Tucson, AZ is preparing the first resource estimate of the project based upon drill results through November 14, 2007. The data base will include 16,576 meters of diamond core drilling in ninety-eight drill holes. The resource estimate, in conjunction with the final column leach test results, will provide the basis for the scoping study and Preliminary Economic Assessment for the first quarter 2008. Additional resource estimates will be performed as drilling results warrant.

All diamond drilling has been performed using HQ diameter core with recoveries averaging greater than 95%. Core is logged and split on site under the supervision of Bear Creek geologists. Sampling is done on two-meter intervals and samples are transported by Company staff to Juliaca, Peru for direct shipping to ALS Chemex, Laboratories in Lima, Peru. ALS Chemex is an ISO 9001:2000-registered laboratory and is preparing for ISO 17025 certification. Silver, lead, and zinc assays utilize a multi-acid digestion with atomic absorption ("ore-grade assay method").
