VANCOUVER, March 13, 2013 /PRNewswire/ - 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.
