BEAR CREEK ANNOUNCES APPROVAL OF CORANI ESIA, PERU
The Peruvian Ministry of Energy and Mines has approved the
environmental and social impact assessment for Bear Creek Mining Corp.'s Corani
silver- lead-zinc project located in southern Peru.
Corani represents a rare asset class containing 270 million ounces of
silver and 4.8 billion pounds of combined lead and zinc which is
forecasted to produce over 13 million ounces of silver per year at a
negative cost of 45 cents per ounce of silver, net of byproduct credits,
for the first five years of a 22-year mine life. Subsequent steps in the
advancement of the Corani project are intended to include detailed
engineering followed by construction permits flowing from the ESIA.
Andrew Swarthout, Bear Creek's chief executive officer, states: "We sincerely appreciate
the strong support from the local communities and the various Peruvian
ministries, including MEM, during the approval process. We also
express our gratitude to the Peruvian central government for
establishing investments in infrastructure along side of our
life-of-mine community investment commitments. Bear Creek is excited to
move this important project forward towards development."
Mr. Swarthout continues: "We are also encouraged by recent conversations
with the Peruvian government towards the resolution of issues regarding
the Santa Ana silver project, which remains under the conditions of the
supreme decree issued in June, 2011. The successful resolution of these
issues and returning Bear Creek's right to operate Santa Ana is
critical to the company's ability to raise financing for the
construction of Corani. Based upon the successful acquisition of the
social license through long-term community investment agreements at
Corani, we strongly believe that the model has been demonstrated that
will establish social license at Santa Ana. We look forward to working
with the government and local communities in reaching a resolution
thereby avoiding ongoing and future litigation while providing the
opportunity for advancing Santa Ana and providing much needed
employment, investment, and revenues in those local communities."
All of Bear Creek's exploration programs and pertinent disclosure of a
technical or scientific nature are prepared by or prepared under the
direct supervision of Andrew Swarthout, PGeo, chief executive officer, who serves as the
qualified person under the definitions of National Instrument 43-101. The block model
estimate, mine design and schedules were prepared by Independent Mining
Consultants of Tucson, Ariz. John Marek, PE, acted as the
independent qualified person as defined by Canada's National Instrument
43-101. Additionally the methods used in determining and reporting the
mineral reserves and resources are consistent with the CIM best
practices guidelines. The method used in the resource calculation is
equivalent to the method used in the resource calculation shown in the company's Aug. 23, 2006, press release. For this resource estimate Bear Creek has used
metal prices based on a three-year backward average and a two-year forward
price based on the metal markets in August, 2011.
Assumptions used in the mineral reserve and FS model by IMC are:
- Silver
price: $18 per ounce;
- Zinc price: 85 cents per pound;
- Lead price: 85 cents per pound;
- Mixed
sulphide material silver recovery is fixed at 62 per cent to lead con and an
additional 14 per cent to the zinc con when zinc head grade is greater than
0.7 per cent, 10.4-per-cent silver recovery when zinc head grade is from 0.7 per cent to 0.5 per cent, 6.3-per-cent
recovery of silver to the zinc con when zinc head grade is from 0.5 per cent to
0.3 per cent and no silver recovery to the zinc con when zinc head grades are
less than 0.3 per cent;
- Zinc recovery: 67.5 per cent to zinc con when the zinc head
grade is greater than 0.7 per cent, 50-per-cent zinc recovery when zinc head grade is
from 0.7 per cent to 0.5 per cent, 30-per-cent recovery of zinc to the zinc con when zinc head
grade is from 0.5 per cent to 0.3 per cent and no zinc recovery to the zinc con when
zinc head grades are less than 0.3 per cent;
- Lead recovery: 75 per cent to lead con;
-
For transitional material silver recovery: 38.5 per cent plus 0.2 times silver grade (g/t)
(maximum 70-per-cent recovery) to lead con and 0 per cent to the zinc con;
- Zinc
recovery: 0 per cent to zinc con and lead recovery: 38 per cent plus 10.9 times lead grade (per cent)
(maximum 65-per-cent recovery) to lead con;
- Average smelter charges including
treatment charges and refining charges and metal deducts
against saleable metal:
- Silver: $1.52 per ounce;
- Zinc: 62 cents per pound;
- Lead: 41 cents per pound;
- Mining costs per tonne: $1.34;
- Process cost per
tonne: $8;
- General and administrative per processed tonne: $1.20;
- Pit slopes: 42 degrees in
mineralized tuff and 46 degrees in postmineralized tuff;
- The
resulting mineral reserve cut-off is $10.54 per tonne ore NSR;
- The mineral
reserves are contained within a practical mining plan that utilized the
floating-cone method as an initial guide for design.

The mineral resource portion of the project is contained in a larger pit
than the FS design pit, which was a floating cone using the following
input assumptions:
- Silver price: $30 per ounce;
- Zinc price: $1 per pound;
- Lead
price: $1 per pound;
- Mixed oxide material that was given 0-per-cent recovery for the
reserves was assumed to have an 85-per-cent recovery of silver, all other
recoveries remained the same. The mineral resource cut-off was
$9.20 per tonne which represents the internal process cut-off. All
metallurgical material types were included in the resource.
All diamond drilling has been performed using HQ-diameter core with
recoveries averaging greater than 95 per cent. Core is logged and split on
site under the supervision of Bear Creek geologists. Sampling is done
on two-metre 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 multiacid digestion with atomic absorption. The quality assurance/quality control program includes the insertion every 20th sample
of known standards prepared by SGS Laboratories, Lima. A section in
Bear Creek's website is dedicated to sampling, assay and quality
control procedures.
The FS was prepared by a team of independent engineering consultants.
The mining and block model portion was prepared by Independent Mining
Consultants of Tucson, Ariz., John Marek, PE, acting as qualified person. The process
plant design was prepared by M3 Engineering, Dan Neff, PE, acting as qualified person.
Metallurgy and process design criteria developed by Blue Coast
Metallurgy Ltd. Chris Martin, CEng, acting as qualified person. And geotechnical,
environmental, infrastructure, waste stockpile and tailings designs
were prepared by Global Resource Engineering Ltd., Chris Chapman, PE,
acting as the qualified person. Each of these individuals has read and approves the
respective scientific and technical disclosure contained in this news
release. Silver equivalency calculation represents the contained
equivalent silver ounces contained in the ground and is based on the
resource metal prices assumptions of $18 per ounce silver, 85 cents per pound and
85 cents per pound zinc, and recoveries to concentrate of 64.2 per cent for silver and 71.1 per cent
for lead and 51.6 per cent for zinc. The calculation does not take into
account the net smelter payment terms for the different metals in the
two separate concentrates. The resulting equivalency is one ounce silver equals 19.1 pounds lead and one ounce silver equals 26.3 pounds zinc.
Total cash cost per ounce of silver is calculated in accordance with a
standard approved by the Silver Institute, a non-profit international
association that draws its membership from across the breadth of the
silver industry. Adoption of the standard is voluntary and the cost
measures presented may not be comparable with other similarly titled
measures of other companies. Total cash cost includes mine site
operating costs such as mining, processing, administration, and
treatment and refining charges, but is exclusive of amortization,
reclamation, capital, exploration costs and taxes on income. Total cash
costs are reduced by lead and zinc byproduct revenues, and then
divided by silver ounces sold to arrive at total cash cost of per ounce
of silver, net of byproduct revenues. Previously, the company
included reclamation costs as a component of its total cash cost per
ounce of silver.
The company has elected to follow the Silver Institute's cash cost
standard, and has therefore excluded reclamation costs from its
calculation of total cash cost per ounce of silver.
We seek Safe Harbor.
