Copper Fox Metals Announces Positive Results of Preliminary Feasibility Study on Schaft Creek Copper-Gold-Molybdenum-Silver Deposit
PRELIMINARY FEASIBILITY STUDY PROJECTS PRE-TAX 18.6% IRR, US$11.7 BILLION UNDISCOUNTED PRE-TAX CASH FLOW AND 4.7 YEAR PAYBACK.(CALGARY, SEPTEMBER 15, 2008) Copper Fox Metals Inc. (CUU-TSX-V, CPFXF-S/P) announced today that the National Instrument 43-101 ("NI43-101") compliant Preliminary Feasibility Study ("PFS") on its 70% owned Schaft Creek deposit in northwestern British Columbia indicates the deposit can be developed economically as an open pit mine and recommends going to a full feasibility study.
The study projects (
see Appendix A for: "Key Project Parameters and Results"):
- A Measured and Indicated Resource of 1.393 billion tonnes with 0.25% Cu, 0.18g/t Au, 0.019% Mo, 1.55g/t Ag at a Copper Equivalent of 0.20% cutoff;
- A Mineable Reserve mill feed of 812.2 million tonnes of 0.301% Cu, 0.212g/t Au, 0.020% Mo and 1.76g/t Ag;
- 18.6% before tax internal rate of return;
- $11.734 billion Pre-Tax Cash Flow (undiscounted);
- $2.764 billion NPV before taxes, discounted at 8%;
- The revenue generated by all the by-products covers all operating costs and adds a credit of (US) $0.32 /lb of copper produced to the revenue stream. Thus, a negative operating cost for copper is estimated;
- 4.7 years before tax payback, and 4.9 years after tax payback.
"We are extremely pleased with the results of this study," said Guillermo Salazar, President and CEO of Copper Fox Metals Inc. "This study represents a major milestone in the progress to develop Schaft Creek and positions us to move forward in fall 2008 with the full Feasibility Study. We have already started this work expected to be completed in the first half of 2009".
For the base case, recoverable rock value per tonne is US $31.47 and cash operating costs are US $12.49 per tonne. The PFS confirms the viability of Schaft Creek and highlights the advantages of the project including: location, comparatively low capital expenditure requirements and operating costs and high metal recoveries."
The full report is expected to be available on the
www.copperfoxmetals.com and
www.sedar.com websites in compliance with Regulatory deadlines.

A number of factors affected cost included in the CAPEX and OPEX estimates from the PEA to the PFS, such as increased planned mill capacity (from 65,000 to 100,000 tpd), market, metal price, volatilities of construction material costs and comparable studies about rising OPEX and CAPEX costs from other parties working in the area. These, in turn, led to a review of forecasts and estimates for labour, construction material, sustaining capital and working capital. This resulted in a delay in the release of this study and an increase in the CAPEX and OPEX from those reported in last December's PEA. The Feasibility Study, is expected to be completed in first half of 2009.
Option Agreement with Teck Cominco LimitedAt present Copper Fox has earned a 70% direct participating interest in the project from Teck Cominco Ltd, through an option agreement dated January 1, 2002. The agreement stipulates that:
- Copper Fox can earn a further 23.4% indirect carried interest in the project upon completion of a positive Feasibility Study.
- Teck Cominco has a right to buy back a 20%, 40% or 75% interest in Copper Fox's interest in the project by matching one, three or four times Copper Fox's expenditures. This right expires 120 days after Copper Fox has presented a positive Feasibility Study, as defined in the Option Agreement, to Teck Cominco.
- In the case of a 75% buy back, Teck Cominco is also responsible for arranging all production financing.
Capital CostsTotal initial investment in the project is estimated to be US$2,950,406,000 which represents the total direct and indirect costs for the complete development of the project. Of this figure, US$1,315,484,000 represent direct mine development costs, US$610,108,000 indirect mine development costs, US$459,757,000 are owner's costs US$536,000,000 contingency, and US$28,566,000 are provincial taxes on identified capital expenditures.
The life-of-mine sustaining capital is as follows:

Life of Mine Total direct Taxes are estimated at US$4,041,652,000.
Cash Operating CostsCash Operating Costs are estimated at US$12.49 per tonne of ore for the life of the mine. Average costs are US$4.14/t for mining, US$3.94/t for milling, US$0.93/t for general and administration, and US$3.49/t concentrate handling and treatment.
The revenue generated by the production of molybdenum, gold and silver (US$14.36/t) leaves a positive balance of US1.87 $/t. This translates into an additional credit to the copper production of US$0.32 /lb of copper produced.
FINANCIAL FORECASTThe independent PFS reports that development of the Schaft Creek deposit is expected to produce a pre-tax Internal Rate of Return (IRR) of 18.6% and an 8% discounted Net Present Value of (US)$2,764,475,000 dollars. The base case financial evaluation uses historical three year trailing averages for metal prices as of August 29, 2008. This approach is consistent with the guidance of the United States Securities and Exchange Commission, is accepted by the Ontario Securities Commission and is industry standard.

Development PlanThe PFS recommends development of the Schaft Creek deposit as a conventional open pit, electrified, diesel truck and shovel operation. The sulphide deposit is expected to be processed using a conventional concentrator to produce separate copper-gold-silver and molybdenum concentrates.
The mill is designed to have a nominal capacity of 100,000 tonnes of sulphide ore per day. Including low grade and stockpile ore, the annual stripping ratio is estimated at 1.88 to 1.
Over a projected mine life of 22.6 years, the mill is expected to produce 4.76 billion pounds of copper, 255.2 million pounds of molybdenum, 4.5 million troy ounces of gold and 32.5 million troy ounces of silver. Rhenium is recovered in the molybdenum concentrate in significant quantities. At a present price of $350 per gram of pure rhenium this may represent a significant additional contribution to income. Copper Fox will report further results with respect to rhenium during the feasibility phase of the project.
Should Teck Cominco decide to exercise their back-in right to acquire 75% of the ultimate 93.4% Copper Fox interest in the Schaft Creek Project, it is expected to be responsible for securing financing for Copper Fox's portion as well as theirs. Copper Fox shall pay back its portion of the project debt out of project revenues. By this time Copper Fox is expected to own 23.35 % of the revenues generated by the project and is expected to pay its portion of the debt financing from revenue generated by production income from its 23.35 % equity of Schaft Creek.
Under such a scenario Copper Fox's share of production is projected to be 1.11 billion pounds of copper (22,400 tonnes per year), 1.05 million ounces of gold (46,500 ounces per year), 59.6 million pounds of molybdenum (2.64 million pounds per year), and 7.6 million ounces of silver (336,000 ounces per year) over the 22.6 year mine life. The Preliminary Feasibility Study reports start of production to be late 2013.
Environment & PermittingRescan-RTEC, a well regarded environmental consulting firm, has been engaged to assist Copper Fox in the permitting of Schaft Creek. Initial permits to support commencement of production are expected to be obtained in the fourth quarter of 2013 in time for sales of concentrates starting in 2014. Copper Fox is working with all levels of government and the Tahltan Nation to complete a streamlined assessment and permitting process.
FIRST FIVE YEARS PRODUCTION SCHEDULEAt a mill capacity of 100,000 tonnes per day, the mill feed for the first five years is expected to be a minimum of 180.0 million tonnes with a grade of 0.32% copper, 0.017% molybdenum, 0.237 g/t gold and 1.587 g/t silver. These higher grades are expected to be a contributing factor to the rapid repayment of CAPEX.
MILL RECOVERIESMill recoveries are projected to be: copper to the copper concentrate: 88.4%, molybdenum to the molybdenum concentrate: 71.3%, gold to the copper concentrate: 81.3%, silver to the copper concentrate: 70.7%.
- The grades of the copper concentrate are expected to be: copper, 33.85%, gold, 21.9 g/t, silver, 158.3 g/t.
- The grade of the molybdenum concentrate is 50.0%, and assays 368 ppm rhenium.
The copper grade in the copper concentrate is higher grade than industry standard chalcopyrite concentrate because of the bornite content and should command a premium from smelters and refiners seeking this product. The rhenium content of the molybdenum concentrate is expected to possibly command a premium.
RESOURCE ESTIMATESThe resource estimates prepared in 2006-2007 by Associated Geoscientists Ltd. were reviewed and a new pit optimization plan was designed by Moose Mountain Technical Services Ltd. of Calgary. The 100,000 tonnes per day pit and mill feed optimization plan presented in the NI 43-101 compliant PFS is expected to extract 812.2 million tonnes of minable reserve with a head grade of 0.301% copper, 0.020% molybdenum, 0.212 g/t gold and 1.761 g/t silver. A total of 1.54 billion tonnes of waste rock (LOM waste to ore ratio of 1.88) is expected to be removed concurrently with mining and milling.
COPPER FOX ACHIEVEMENTSSince the formation of Copper Fox, the company has spent in excess of 32 million CDN dollars in developing the Schaft Creek mineral deposit. Copper Fox is positioned to complete the full Feasibility Study of the deposit and readying Schaft Creek for production at a minimum of 100,000 tpd.
Key development achievements include:
- Improving historical core recoveries by drilling wider diameter holes and using state of the art drilling technology that has resulted in higher gold assays, but confirmed the historical copper, molybdenum and silver assay database.
- Confirming the capability of separating copper, gold and silver from molybdenum and the gangue materials and
- Demonstrating the capability of running a conventional 100,000 tpd mine and mill complex that would produce high quality copper-gold-silver and molybdenum-rhenium concentrates.
- Metal Recoveries have improved substantially.

(*) Hecla Mining Co. (1969-1978) & Teck Cominco Ltd (1978-2002) Social LicenseSince 2005, Copper Fox has worked with the Tahltan Nation to develop a relationship based on open, honest and transparent communication. The company has done this by entering into agreements with the Tahltan Central Council (TCC) and the Tahltan Nation's government, with the aim of building a solid working relationship. These agreements include: the Communications Agreement, which provides funding to build communications capacity within the TCC; the Tahltan Heritage Resources Environmental Assessment Team (THREAT) agreement, which outlines how the company works with THREAT through the environmental assessment process; the Heritage Agreement, which outlines how the company is expected to protect the heritage and cultural resources of the Tahltan Nation within the Schaft Creek Project area; and a Memorandum of Understanding (MOU) between the company and the Tahltan Nation Development Corporation (TNDC) which ensures that Copper Fox will hire Tahltan workers and use Tahltan suppliers when price and quality are comparable.
In addition to these agreements, Copper Fox has provided support to initiatives and projects that support the advancement of Tahltan youth and culture. These include: support for the Tahltan Language Camp, Youth Science Camp, bursaries to support continuing education and support for the Resource Forum.
As part of its commitment to open communication, Copper Fox has hosted open houses in the Tahltan communities of Dease Lake, Iskut and Telegraph Creek as well as the northern communities of Smithers, Terrace, Stewart and Kitimat. As the Schaft Creek Project advances towards feasibility these community meetings will continue and the company will seek further feedback on the project.
Enhancement Opportunities:Samuel Engineering notes that the economics in the PFS do not take into account opportunities for improvement of the project economics based on:
- Further improvements to the process design based on additional metallurgical test work, for example:
- optimizing primary and secondary grind size -- thus reducing grinding circuit size and power;
- optimizing rougher and cleaner flotation circuits -- thus reducing both size and number of flotation cells;
- optimizing concentrate grades;
- optimizing solid/liquid separation -- thus reducing size of thickeners and filters.
- Optimize tailings deposition method;
- Optimization of mill location;
- Inclusion of revenue from rhenium;
- Increasing the overall resources of the deposit;
- Conversion of Inferred Resources into Measured and Indicated Resources; and
- Sharing of infrastructure development costs and power with neighbouring potential producers and other stakeholders.
