VANCOUVER, Sep. 14, 2009 (Canada NewsWire via COMTEX News Network) --
Bear Creek Mining Corporation (TSX Venture: BCM) ("Bear Creek" or the "Company") is very pleased to announce the results of a positive Prefeasibility Study ("PFS"),) as defined by NI-43-101 for its 100% owned Corani silver-lead-zinc deposit located in southern Peru. Highlights of this study include (all figures in US dollars):
<<
- The net present value is $348 million at a 5% discount rate and the
after tax internal rate of return for the project is 25%
- Proven and Probable Mineral Reserves containing 258 million ounces of
silver, plus 2.9 billion pounds of lead and 1.4 billion pounds of
zinc, respectively
- Average annual saleable silver production of 10M ounces per year for
first 6 years, 6.4M opy LOM. On a silver equivalent ounce basis,
17.1M opy for the first six years and 12M opy for the life of the
project
- Project produces two highly-marketable concentrates
- Cash cost of $1.06 per ounce silver for the first 10 years, LOM cash
costs of $2.81 per ounce (net of base metal credits)
- Metals price assumptions; $13/oz Ag, $0.70 Pb, and $0.65 Zn
- Capital costs of $339 million with Capital Payback in less than three
years
- Life of Mine 27 years
- Mill capacity 15,000 tonne per day
- Stripping ratio of 1.56:1 (Waste:Ore)
- Feasibility Study to be initiated
>>
Project summary - The project has an after-tax internal rate of return (IRR) of 25%, net present value of $348 million at a 5% discount rate and a EBITDA of $1.8 billion based upon metals prices of $13 per ounce silver, and $0.70 and $0.65 per pound of lead and zinc, respectively.
Recovered silver production in the first six years averages 10 million ounces/year and the project will produce an average of 6.4 million payable ounces of silver, 73 million pounds of lead and 32 million pounds of zinc annually over a 27 year mine-life. Life of mine cash cost per ounce of silver is $2.81, net of base metals credits and $1.06 per ounce silver for the first 10 years. Pre-production capital investment in the project is estimated to be $339M and sustaining capital expenditures are estimated at an average $13.1 million per year over the 27-year life of the mine. Based upon the aforementioned metals prices, the project achieves payback of capital in 2.9 years. The Prefeasibility Study has been prepared using cost bids and estimates and production forecasts provided by qualified engineering consulting groups and the economic analysis was done in conjunction with Bear Creek's financial advisor.
Andrew Swarthout, President and CEO, states, "We are very pleased that the prefeasibility study establishes Corani as a large, robust silver and base metals deposit now advancing to full feasibility. Using current spot metals prices ($16.85/oz silver, $0.86/lb zinc, $0.97/lb lead), Corani has an NPV of approximately $757M at a 5% discount rate and a 41% IRR after tax showing that the project is highly leveraged to rising metals prices. The study describes the project as imminently buildable using conventional mining and processing technology. We are particularly pleased that the Prefeasibility Study meets our expectations for maximizing the value of the project: namely, creating a higher grade mine, dramatically lowering capital costs, and balancing metal recoveries into two highly marketable and separate lead and zinc concentrates. In addition to the leverage to conservative metals prices used in the study, our engineering consultants have identified several additional opportunities such as increased throughput and contract mining alternatives to further enhance value during the Feasibility Study."
<< PREFEASIBILITY STUDY >>
The reserve and resource estimates were updated for the PFS by Independent Mining Consultants (IMC), Tucson, AZ. Samuel Engineering, Denver, Colorado and Vector Engineering, Lima, Peru co-lead the study with support from Resource Development Inc. (RDI) (Metallurgy), and SGS Vancouver (Metallurgical Testing). All are independent preeminent engineering and metallurgical testing firms with recent mine development and operating experience in Peru.
The PFS, which is dated effective Monday September 14th, 2009, is based upon mining assumptions derived from mine planning sequences completed by IMC and metallurgical test work performed by SGS Laboratories and G&T Metallurgical. The mining sequence primarily derives ore from the higher-grade starter pits in the early years and moves to lower-grade areas in the later years of production. Operations are to be 27 years based on current reserves. Only measured and indicated resources were used when defining the operations plan when converting resource to reserves. Note that in the mine sequence, only 258 million ounces contained within 139.6M tonnes have been used as reserve in this plan. An additional 110.4M additional tonnes of measured and indicated resource (containing 71.8 million ounces of silver) and 34.2 million tonnes of inferred resource (containing 35.6 million ounces of silver) remain that could be included in later plans of operations should metals prices and/or operating parameters (recoveries) improve.

The PFS is based upon an updated resource estimation and mine sequencing performed in August 2009 by IMC based upon 93,577 meters of drilling and sampling in 544 diamond drill holes and trenches completed through August 2009. The Company employs a Net Smelter Return (NSR) method to determine the break between ore and waste, with the cutoff NSR being $9.10 per tonne. Measured and Indicated Resources contained within the pre-feasibility study design pit were used to determine final pit limits and thus converted respectively into Proven and Probable Reserves. Importantly, 71% of the previously reported ounces of silver in resources were converted to reserves in this study. The additional resource material is mostly measured and indicated resource that occurs outside of the pre-feasibility study pit but which meets the CIM definition of mineral resource.
Metallurgical testing - The Company has completed metallurgical optimization tests on two master composites in order to define recoveries for the purposes of the PFS reserve calculation. The composites were designed using a blend of the Mixed Sulfide and the Transitional ores which constitute 82% and 18% of the ore deposit, respectively. The composites therefore approximate the expected life of mine concentrator feed material (see also "Mining and Milling"). The master composite test work establishes that when the two materials are blended in accordance with the mine sequence that the recoveries and resulting concentrate grades are as outlined in the table below. Additionally the Company has completed a re-logging of all drill core to identify the different metallurgical material types. The re-logging data was then utilized to define each block in the resource model with a metallurgical rock type and assigning every block a specific recovery and concentrate grade for the purposes of determining its NSR value and reserve classification. The specific grade and recovery parameters used for the flotation ores, the life-of-mine overall recoveries and concentrate grades are tabulated below.

MINING AND MILLING
>>
Mining will be performed using conventional open pit methods using 90t trucks and 12m(3) wheel loaders mining on 8 meter high benches. The mine requires minimal pre-production waste stripping of 10.8 million tonnes.
Processing of the ore will be by conventional flotation recovery methods. The ore will be crushed close to the mine and the material conveyed to the processing plant where it will be ground to 80% passing 106 microns in a SAG/Ball mill circuit. The material will then be floated with the rougher concentrates being reground to 80% passing 35 microns prior to cleaning to produce high-value separate lead-silver and zinc concentrates. Concentrates will be trucked to the Port of Maturani for ocean shipment to smelters.
<< CAPITAL COSTS >>
The project capital cost estimate has been prepared by three independent engineering companies. The mining costs were prepared by Independent Mining Consultants of Tucson, Arizona, the Process and part of the infrastructure capital cost has been prepared by Samuel Engineering of Denver, Colorado and the Tailings and remaining infrastructure costs have been prepared by Vector Peru. The initial startup capital is estimated to be $339 million and the total life of mine capital cost is estimated to be $693 million. The capital costs include detailed long-term plans for tailing dam expansions as well ongoing capital and mine closure.
<< OPERATING COSTS >>
Mining costs were prepared on a year by year basis with costs varying mostly due to changing haulage distances. The life-of-mine average mining costs will be $1.50 per tonne of the total material moved. The process costs are estimated to be $7.30 per tonne of process ore and the G&A is estimated to be $1.20 per process tonne or $6.3 million per year.
<< INFRASTRUCTURE >>
The project has favorable infrastructure. Access will be via a new 63 km road to be built over flat topography resulting in low construction costs. The new road will connect to the Interoceanic Highway; a two-lane, paved highway connecting to the port of Matarani. The mine is 30 km from a new high-voltage power line with abundant capacity to meet the project needs. The project has an excellent site for tailings storage resulting in a very low capital and operating cost as the plant will be located immediately adjacent to the tailings pond. The site is also located in the upper part of the Atlantic drainage and as such there are several surface and underground water source alternatives.
<< ENVIRONMENTAL AND SOCIAL >>
The project has been designed to meet international standards of environmental compliance. The tailing storage facility has been designed to the highest standards of containment and stability. The waste rock storage facilities are designed to capture and manage any flows that may originate from the waste rock. Finally an initial closure plan has been developed that will provide covers for both the tailing storage and waste rock facilities that will result in safe and environmentally compliant closure of the mine. The Company has maintained very good working relationships with the local communities.
<<
OPPORTUNITIES
The study has identified areas of opportunities that will be analyzed in
later engineering studies and test work:
- Increase throughput while maintaining much of the same low start-up
cost infrastructure.
- Investigate the use of contract mining to reduce the start-up and
sustaining capital
- As the sensitivity analysis shows, the project is very sensitive to
metallurgical recoveries. The Company and its consultants believe
continued metallurgical optimization test work may further improve
the metal recoveries and concentrate grades.
The PFS will be filed and available for viewing on SEDAR (www.sedar.com)
within 45 days following the date of this news release.

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 Marc Leduc, P. Eng., Senior Vice President of Engineering and Development and the President and CEO, Andrew Swarthout, P.Geo., who serve as the Qualified Persons under the definitions of NI 43-101. The block model estimate, mine design and schedules were prepared by Independent Mining Consultants of Tucson Arizona. John Marek P.E. 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 our August 23, 2006 Press Release. For this resource estimate we have used metal prices based on a 3-year backward average and a 2-year forward price based on the metal markets in July 2009.
Assumptions used in the mineral reserve and PFS model by IMC are: Silver Price=$13.00/oz; Zinc Price=$0.65/lb; Lead Price=$0.70/lb; Mixed Sulfide Material Silver Recovery=62% to lead con and 16% to the zinc con, Zinc Recovery=75% to zinc con and Lead Recovery=76% to lead con; Transitional Material Silver Recovery= 56% to lead con and 5% to the zinc con, Zinc Recovery= 20% to zinc con and Lead Recovery= 52% to lead con. Average smelter charges against saleable metal: Silver= $0.68 per ounce; Zinc= $0.348 per pound; Lead= $0.286 per pound; Mining Costs per tonne= $1.25; Process cost per tonne= $7.00; G&A per processed tonne= $0.85; Pit Slopes= 42 degrees in mineralized tuff and 46 degrees in post-mineralized tuff. The resulting mineral reserve cutoff is $9.10/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 PFS design pit, which was a floating cone using the following input assumptions: Silver Price=$13.85/oz; Zinc Price=$0.693/lb; Lead Price=$0.746lb; Mixed Sulfide Material Silver Recovery=68% to lead con and 17% to the zinc con, all other recoveries remained the same. The Mineral Resource cut-off was $7.85/tonne which represents the internal process cutoff. 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%. 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"). The QC/QA 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 PFS was prepared by a team of independent engineering consultants. The mining and block model portion was prepared by Independent Mining Consultants of Tucson Arizona, John Marek, PE acting as QP. The process plant design was prepared by Samuel Engineering, Kathy Altman, PE acting as QP. Metallurgy and Process design criteria developed by Resource Development Inc. Deepak Malhotra, Ph.D acting as QP. And geotechnical, environmental, infrastructure, waste stockpile and tailings designs were prepared by Vector Peru, Scott Elfen, PE acting as the QP. 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 sent to concentrate and is based on the resource metal prices assumptions of $13.00/oz Ag, 0.70/lb Pb and 0.65/lb Zn and recoveries to concentrate of 74.5% for silver and 71.7% for lead and 71.3% 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 1 oz Ag = 19.3 lb Pb and 1 oz Ag = 20.9 lb Zn.

VANCOUVER, Jun 17, 2010 (Canada NewsWire via COMTEX News Network) --
Bear Creek Mining (TSX Venture: BCM) ("Bear Creek" or the "Company") is pleased to announce results for 43 additional diamond drill holes (4,567.8 meters) that will be incorporated into an updated resource/reserve estimation in the next month. Drilling at Santa Ana, a pure silver, heap leachable deposit capable of producing close to 5 million ounces per year (see news release dated 20 April 2009), now totals 64,761 meters in 393 drill holes including 45 holes engineering holes totaling of 4,303 meters. Santa Ana is located 200 kilometers south of the Company's world-class Corani silver-base metal deposit in southeastern Peru. Both projects are in the feasibility study stages. Highlights of this press release include:
<<
- Feasibility Study on-track for September 2010.
- Infill holes are returning similar silver values to previous
drilling; therefore, good conversion from inferred to M+I resources
and mineable reserves is expected.
- Drill hole SA-227 intersects 34m @ 81.2 g/t Ag including 10m @
140.4 g/t Ag.
- Drill hole SA-230 intersects 24m @ 64.6 g/t Ag, including 6m @
185.0 g/t Ag.
- Drill hole SA-237 intersects 24m @ 86.8 g/t Ag.
- New style of base metal-rich (up to 3.6% combined Pb-Zn) + silver (up
to 63 g/t) mineralization intersected in four drill holes (SA-221,
222, 241, and 241A) at drilling margins, indicating additional
potential towards the untested "North Anomaly".
- Mineralization remains open laterally and at depth.
>>
Andrew Swarthout, President and CEO of Bear Creek, states "We are very pleased with the advances at Santa Ana. The data is indicating that our upcoming Feasibility Study will describe a project which exceeds the expectations presented in the April 2009 Preliminary Economic Assessment ("PEA"). Additionally, there continue to be pleasant surprises as we perform step-out drilling in this large, unexplored district."

VANCOUVER, Jul 12, 2010 (Canada NewsWire via COMTEX News Network) --
Bear Creek Mining Corporation (TSX Venture: BCM) ("Bear Creek" or the "Company") is very pleased to announce results from the fourth resource estimate at the Company's 100% owned Santa Ana leachable silver deposit. This resource estimation will be used to derive the mineable reserves and mine planning for the Santa Ana Feasibility Study expected to be completed in September 2010. Santa Ana is located in southeastern Peru, 200 kilometers south of the Company's Corani silver-base metal deposit which is also undergoing a final Feasibility Study. Highlights of this press release include:
RESOURCE ESTIMATION
<<
- Current Silver resources are:
- Measured and Indicated 101.8M tonnes grading 41.5 g/t Ag
containing 136M ounces silver
- Inferred 21.6M tonnes grading 40.6 g/t Ag containing
28.2M ounces silver
- Deposit still open in 4 directions
- 39% increase to 136M ounces silver in M&I from the previous estimate
of 98M ounces
- Mineralization remains open to the north, south and west plus at
depth
>>
Andrew Swarthout, President and CEO of Bear Creek, states "We are very encouraged with the fourth resource estimation completed on the Santa Ana leachable silver deposit. Measured and Indicated resources again increased significantly demonstrating the strong continuity of the mineralization and allowing for the continued conversions of what was previously categorized as waste to mineralized material and Inferred resource to Measured and Indicated resources. The Feasibility Study will now focus on optimal mining cut-off grades for conversion to mineable Proven and Probable reserves. The resource estimation confirms the robust project described by the Preliminary Economic Assessment ("PEA") with potentially a 50% longer mine life than previously envisioned."
Mr. Swarthout continues "Ongoing metallurgical testing continues to indicate that the project can employ low-cost open-pit mining and heap leaching with at least 70% silver recoveries. The engineering work indicates that the infrastructure is favorable for mine development and that capital costs will remain in-line with those presented in the PEA with further optimization opportunities being evaluated."
RESOURCE ESTIMATE
The updated resource estimation was completed in July 2010 by Independent Mining Consultants (IMC) of Tucson, Arizona, with John Marek, P.E. acting as the Independent Qualified Person under NI 43-101. The resource estimate is based upon 348 diamond drill holes totaling 60,458 meters completed through June. The estimation is presented below using two cutoff grades. The global resource assumes a $16 per ounce silver price applied to mineralized material contained within a pit determined by 70% silver recoveries under heap leaching and operating costs established in the Preliminary Economic Assessment ("PEA") prepared by IMC in April 2009 (see news release dated 20 April 2009). Lead and zinc are not recovered in heap leaching and not considered in the resource estimation. Lead and zinc grades are reported as they are elevated and could become economically significant with additional exploration.

The stripping ratio is approximately 1.65:1. Importantly, the resource model is constrained such that only blocks with nearby drill holes are considered in the resource; therefore, additional drilling is expected to continue to convert waste blocks into resource, further reducing the stripping ratio. The estimation utilized indicator kriging to establish the limits of mineralization. Block grades were then calculated using a linear kriging method incorporating 5-meter drill hole assay composites.
The deposit can be subdivided into the lower-grade periphery and a higher-grade central part of the deposit for which the resources are tabulated below applying a 19 g/t silver cut-off grade for the estimation. This higher grade zone of the deposit contains 101.8 million ounces of silver in a pit with a waste to mineralized material ratio of 1.75:1 (M+I Resources/Waste + Inferred Resources).

Drilling has left the deposit open to the NNW and potential for expansion remains at depth, high-grade and leach grade expansions. Mineralization is typically contained within northerly and northeasterly trending, sub-vertical structural corridors within which high-grade silver mineralization is surrounded by lower-grade halos. Silver mineralization is also found along bedding planes in the thick andesite flow and in sub-vertical, dilational zones within the bedding.
Santa Ana Feasibility Study Progress
Work is continuing on the preparation of the Santa Ana Feasibility Study and Environmental and Social Impact Assessment (ESIA). The Company expects to release the results of the Feasibility Study in September 2010 and to file the ESIA before the end of the year.

bear find ich gut... allein der name...vor allem aber großartiges potential, habe die kursschwäche zum einstieg genutzt und erwarte nun den ausbruch über die 4€, dann ist wirklich sehr viel luft nach oben, zumal wenn der silberpreis so stark steigt, wie man es wohl erwarten muss
mit der Silberfahrt nach kurzer Korrektur und neuen Silberhöchstständen.
Bear Creek Mining Corp.: Spekulativ kaufen mit Kursziel 7,00 CADParadigm Capital erhöht das Kursziel für den kanadischen Metallexplorer Bear Creek Mining Corporation von 6,25 CAD auf 7,00 CAD, zuversichtlich, dass Bear Creek schon bald Gold und Silber in seinen peruanischen Projekten Santa Ana und Corani produzieren wird. Diese Projekte haben zwar die gleichen Metalle, unterscheiden sich aber stark.
Corani, teuer in der Entwicklung aber günstig im Betrieb, könnte jährlich 6 - 9 Mio. Silberunzen zu etwa 2 USD/oz produzieren. Santa Ana, günstig in der Entwicklung aber teuer im Betrieb, nutzt das günstiger zu bauende Haufenlaugungsverfahren, das sich aber nur für Silber eignet. Für Santa Ana wird noch diesen Monat eine Machbarkeitsstudie erwartet. Eine Abgrenzungsstudie vom April 2009 prognostizierte eine Jahressilberproduktion in Santa Ana von 4,6 Mio. Unzen über 12 Jahre im Haufenlaugungsverfahren. Seitdem haben neue Bohrungen höhere Schätzungen ergeben.
Die Produktion soll im ersten Quartal 2012 beginnen. Das Corani Projekt hingegen braucht wohl noch mehr Zeit, da weitere Tests durchgeführt werden müssen und auch der Genehmigungsprozess länger dauern kann. Paradigm erwartet eine Produktion erst im Jahr 2014.

16.09.2010 17:24 BEAR CREEK PROVIDES PROJECT UPDATES; KEY SURFACE RIGHTS TO BE ACQUIRED AT CORANI AND SANTA ANA SILVER DEPOSITS, PERU
VANCOUVER, Sept. 16 /PRNewswire-FirstCall/ -- Bear Creek Mining Corporation (TSX Venture: BCM) ("Bear Creek" or the "Company") is very pleased to provide updates on its Corani and Santa Ana feasibility studies. At Corani, 1,133 hectares of surface land acquisition is scheduled for closure later this year. This land purchase will comprise over 50% of the project infrastructure needs and importantly, the acquired surface will cover approximately 30% of the ore deposit and is pivotal to the acquisition of remaining surface rights before year-end.
Final bids from engineering firms for the Corani Feasibility Study are currently being reviewed for awarding of the contract in early October. Significant opportunities being taken into the Corani Feasibility Study include:
- Throughput optimization will immediately be evaluated for potential plant capacity to increase by 50% from the prefeasibility study to 22,500 tonnes per day. - Subject to the feasibility study results on increased plant capacity, silver and base metals output would increase by 50% per year to approximately 15 million ounces per year with only an approximately 20% increase in capital required for larger mills, flotation capacity, and increased initial tailings dam requirements. - Assuming that the larger plant size analysis is positive, increasing throughput will take the mine life from 27 years to less than 20 years resulting in further improvement to IRR and NPV.
Feasibility-level metallurgical testing continues towards further process optimization focusing on the first five years of commercial production. Test results are in line with the Prefeasibility Study completed in September 2009 (See news release dated 14 September 2009). The Corani Feasibility Study is expected to be completed in the 3rd Quarter 2011.
Santa Ana Project - Land acquisition at Santa Ana is advancing with completion also expected by year-end 2010. Water wells have been drilled and are currently being tested for two alternative process water sources for the Feasibility Study. The Feasibility Study is in the final stages with completion expected in early October, leading to the submission of the environmental impact study before year-end 2010 followed by formal construction permit applications. Given that approval of final permits generally takes nine months from submission, the Company envisions construction commencing by Q4 2011. First silver production is targeted by the second quarter 2012 with ramp-up to an annual production rate of 5 million ounces of silver per year as outlined in the Santa Ana Preliminary Economic Assessment to occur within two quarters after commencement of leaching. (See news release dated 20 April 2009).
Andrew Swarthout, President and CEO of Bear Creek states "The acquisition of these key surface rights and steadily advancing feasibility studies on two separate silver deposits solidly places Bear Creek on track to becoming a 15 million to 20 million ounce per year producer during 2014 with first production coming from Santa Ana in 2012 at a rate of 5 million ounces per year. The Santa Ana feasibility study, due for announcement the first week of October will describe a robust project in-line with the Preliminary Economic Assessment and recent guidance. In addition, the Study will present detailed alternative mine plans taking advantage of recent increases in silver prices."
