Bear Creek Announces Positive Drill Results on Its Sumi Gold Project, Peru

Vancouver, B.C. - Bear Creek Mining (TSX Venture: BCM/ BVL: BCM) (“Bear Creek” or the “Company”) is pleased to announce results for the five (5) diamond drill holes (1105.3 meters) from its Phase I drill program on the Sumi project. Highlights of the results are:

  • Drill hole SU-5 returns 17 meters averaging 3.6 g/t Au and 3.2 g/t Ag from 50.65 to 68 meters depth.
  • Drill hole SU-2 returns 50 meters averaging 0.98 g/t Au and 5.1 g/t Ag from 124 to 174 meters depth.
  • Drill hole SU-1 returns 10 meters averaging 4.4 g/t Au from 69.9 to 80 meters depth.
  • Three cyanide extraction bottle roll tests on drill core ground to 85% passing minus 200 mesh averaged 86.6% gold recovery; two tests on higher sulfide content samples yielded less than 40% recoveries.

Andrew Swarthout, CEO, stated “We are encouraged by these preliminary results from the Phase I program designed to verify and extend near-surface gold mineralization prior to the beginning of the 2012/13 rainy season. Based upon the favorable drilling and bottle-roll extraction tests, Phase II drilling will focus on extending mineralization under the extensive, untested shallow post-mineral cover.”

The Sumi project, 100% Bear Creek owned and not subject to material holding costs, is located in the gold-silver Tertiary-age belt in central Peru and exhibits alteration and mineralization typical of the upper part of an epithermal precious metal deposit. Assay results for 111 surface rock chip samples have returned precious metal values including 15.65 g/t gold and 156 g/t silver in a vein breccia structure over widths of 0.3 to 2.0 meters and 12.1 g/t gold and 102 g/t silver over 2 meters widths in silicified volcano-sedimentary rocks (see news release dated August 16, 2012). Fifty (50) of the 111 assay samples contained anomalous gold > 100 ppb. The prospect was partially tested in 2003 and 2006 by third parties with limited drilling reportedly intersecting multi-gram gold values over intervals ranging from 2 to over 47 meters, beginning at the surface. Furthermore, favorable sedimentary formations have been identified indicating potential for underlying gold mineralization at shallow depths.

Phase I drilling tested a 400 meter by 150 meter area and Phase II drilling, expected to commence in the third quarter of 2013, will test an additional 1000 meters by 500 meters favorable area of the prospect to establish continuity of mineralization and to test additional blind vein and breccia targets beneath shallow, post-mineral cover.
