BEAR CREEK PROVIDES UPDATE ON ITS EXPLORATION PROGRAMS INCLUDING TWO NEW ACQUISITIONS, PERU

April 6, 2011

VANCOUVER, April 6 /PRNewswire/ – Bear Creek Mining (TSX Venture: BCM / BVL:
BCM) (“Bear Creek” or the “Company”) is pleased to provide updates on
its exploration programs in Peru.  The Company maintains an aggressive
generative exploration program while advancing the development of two
new major silver mines, Santa Ana and Corani.  The four prospects
described in this update range from an advanced Phase II drilling
program at Tassa to new acquisitions and discoveries. (To view location

Andrew Swarthout, CEO of Bear Creek, states “We are very pleased to be
advancing our exploration portfolios with two new prospects while
continuing fast track development at our two major mines where first
silver production is expected next year.  Bear Creek has a strong
discovery history and is fortunate to have the funding and exploration
expertise to ramp up strong exploration and drilling campaigns in 2011
on four different prospects.  Our exploration team discovered our two
mines and we remain committed towards discovering the next precious
metals deposit.”

Tassa silver-gold (100% BCM) - Phase II drilling is scheduled to commence in second quarter of 2011
and will follow up on numerous mineralized intercepts from Phase I
including up to 60 meters averaging 224.2 g/t Ag from 24 to 84 meters
depth (see news release dated 12/6/2010) and 40 meters averaging 110.7
g/t Ag from 2 to 42 meters depth as well as scattered anomalous gold
intercepts with up to 1.24 g/t Au over 2 meters.

Tassa is located approximately 160 kilometers northwest and 230
kilometers south of the Company’s Santa Ana and Corani silver deposits
respectively.  The prospect is also located 16 kms north-west from the
Canahuire deposit/ Chucapaca district, currently under exploration by
the Goldfields – Buenaventura joint venture where reported resources
are 83.7 MT averaging 1.9 g/t Au and 8.2 g/t Ag with mineralization
remaining open.  Phase I drilling tested a 1.5 km by 800 meter anomaly
where 852 rock chip samples averaged 30.71 g/t silver. Silver (and
gold) mineralization was intersected contained within multiple phases
of breccias, strongly fractured rhyolitic volcanics, and brecciated
sediments.  Subsequently surface mapping has identified breccia
complexes 1 km further to the north suggesting the continuation of the
hydrothermal breccia complex below the Mesozoic sediments and expanding
the target area by two-fold.  In addition, new surface geochemistry
sampling has identified a 1.04 g/t gold and 0.55% copper anomaly in
quartz-sulfide veinlets which cut the rhyolitic volcanics indicating
that gold mineralization is originating from an underlying untested
source.  Stratigraphic studies suggest that the  favorable sediments
were not reached in the Phase I drilling, therefore, Phase II drilling
will test deeper in the system (up to 450 meters depth) where favorable
sedimentary formations which host the nearby Chucapaca mineralization
are believed to exist in contact with the breccia complexes.  Future
drilling will also focus on new targets adjacent to the breccias
complexes located over the northernmost three by two kms of the
concessions where geologic mapping and sampling have again expanded the
target area.  The Phase II program will consist of approximately 3,000
meters in eight (8) drill holes. (To view Tassa map with expanded

Alejandra gold project - The Company has recently entered into an option agreement with a
Peruvian third party to acquire 1,000 hectares in northern Peru in a
volcanogenic massive sulfide (“VMS”) complex hosting gold and base
metal mineralization.  The option agreement allows the Company to
acquire a 100% interest for payments totaling US$2.64 M over five years
with the initial payment being US$15,000.  Alejandra is located within
the same volcanic complex as the Tambo Grande VMS deposit, located 30
kms to the south-west, which hosts 1.9M ounces gold and 34M ounces
silver averaging 3.5 g/t Au and 64 g/t Ag (oxide deposit) and 191 MT
averaging 1.3% Cu, 1.2% Zn, 0.6 g/t Au and 23 g/t Ag (sulfide deposits)
as reported by Manhattan Minerals in 2002. Initial geologic mapping and
surface sampling defines a target area 4 by 1.5 kms with four styles of
mineralization typically associated with VMS ore bodies: mantos, veins,
stockwork and breccia zones. The mantos are composed of sub-horizontal
lenses hosted in marine volcaniclastic rocks with 0.5 to 1.5 mts width
and values up to 3.6 g/t gold, 28.9 g/t silver and 0.83% Zn. Veins are
comprised of at least two structures with an approximately length of 2
km, 0.2 to 2.0 mts wide containing values up to 9.6 g/t gold, 61.1 g/t
silver, 0.11% copper, 0.19% lead and 0.20% zinc. The stockwork zone,
characterized by quartz-pyrite veining with sericitic halos, is located
in a pervasively altered volcanic rock containing values up to 0.13 g/t
gold, 25.6 g/t silver and 0.13% lead with highly anomalous As, Ba, Cu,
Hg, Sb. A hydrothermal breccia discovered by trenching through shallow
soil cover contains up to 0.76 g/t gold, 29.8 g/t silver and 0.30%
lead. Importantly, over 60% of the area is covered with thin soil and
the more favorable Ereo Formation hosting the large VMS deposits at
Tambo Grande underlie the mineralized outcrops at Alejandra at depths
likely less than 200 meters.  A geophysical program will be designed to
define targets buried under shallow soil cover and additional geologic
mapping will be done to better delineate targets for Phase I drilling
program comprised of 1,500 meters in 10 drill holes to commence in
second half of 2011.  Community relations with local populations are
favorable at Alejandra.

Sumi gold project - The Company holds a 100% interest comprised of 1,200 hectares in a
discovery located in the Au-Ag Tertiary-age epithermal belt in central
Peru where alteration and mineralization in the area is typical of a
volcanic-hosted, high- sulfidation system.  To date, eleven (11)
preliminary surface rock chip samples have returned precious metal
values including 5 g/t gold and 156 g/t silver in a vein- breccia
structure with 0.3 to 2.0 meters width and 0.57 g/t gold and 82.6 g/t
silver in a vuggy silica altered volcanic rock. Eight of the eleven
samples contained highly anomalous gold > 100 ppb. The prospect was
partially tested in 2003 and 2006 by a third party with limited
drilling reportedly intersecting multi-gram gold over intervals ranging
from 2 to over 47 meters beginning at the surface.  The program totaled
approximately 4,600 meters but did not test outcrop areas where BCM
sampling has yielded 5 g/t Au.  Bear Creek’s initial work indicates
that a large prospective area remains untested, including favorable
sedimentary Mesozoic formations similar to Tassa/Chucapaca.    Plans
are to complete detailed surface mapping and sampling in preparation
for Phase I drilling estimated to commence in the second half of 2011.

La Yegua copper-gold-molybdenum project (100% BCM) -  La Yegua is located 20 kms northeast of the 200 MT Los Chancas
copper/gold/moly deposit in a prolific porphyry copper belt that also
contains the Las Bambas,  Huaquira, Constancia, Tintaya and Antapaccay
mines.  Bear Creek has entered into a joint venture agreement with
Japan Oil, Gas and Metals National Corporation (“JOGMEC”) to advance
the La Yegua Project into Phase II drilling.  The agreement provides
for JOGMEC to earn a 51% interest through investing US$3M over a three
year period.  Previous drilling, which intersected up to 114 meters
with 0.24% copper and 0.03 g/t gold, was restricted to a small portion
of the altered intrusive complex before being terminated prior to
completion.  Recent work performed under the new JV agreement has
identified at least two high-chargeability anomalies defined by Induced
Polarization/ Resistivity surveys. These two targets, measuring 700 x
300 meters and 500 x 300 meters, are located at shallow depths 600
meters east and 1.5 kms south-west of previous drilling and strongly
suggest the presence of untested porphyry targets. One anomaly is
associated with a potassic- propylitic altered quartz-feldspar porphyry
intrusive with anomalous copper (500 ppm).  Geologic mapping and
re-logging of drill core is being performed prior to the decision to
commence Phase II drilling in second quarter of 2011.

Consistent with the Company’s aggressive generative exploration
philosophy, several additional prospects in the portfolio are being
evaluated for future drilling or acquisition.
