VANCOUVER, July 11, 2011 /CNW/ - ("Copper Fox" or the "Company") (TSX-V: CUU) is pleased to provide its shareholders the results of the recently completed National Instrument 43-101 compliant resource estimate for the Schaft Creek copper-gold-molybdenum-silver deposit located in northwest British Columbia, Canada.  The resource estimate was prepared by AMEC Americas Limited ("AMEC") and the National Instrument 43-101 compliant report related to the resource estimation will be filed on SEDAR within 45 days.  Highlights of the resource estimate using a 0.20% copper equivalent cut-off (Base Case) are as follows:

Highlights:

1. The Measured mineral resource for the Schaft Creek deposit (at a 0.20% copper equivalent cut-off) is estimated to be 40.3 million tonnes grading 0.36% copper, 0.023% molybdenum and 0.25g/t gold (copper equivalent of 0.61%) containing 319.6 million pounds copper, 20.5 million pounds molybdenum and 0.32 million ounces gold,
2. The Indicated mineral resource for the Schaft Creek deposit (at a 0.20% copper equivalent cut-off) totals 971.2 million tonnes grading 0.27% copper, 0.017% molybdenum and 0.18g/t gold (copper equivalent 0.45%) containing 5.8 billion pounds copper, 363 million pounds molybdenum and 5.5 million ounces gold,
3. The Measured and Indicated mineral resource for the Schaft Creek deposit (at a 0.20% copper equivalent cut-off) totals 1.01 billion tonnes grading 0.27% copper, 0.017% molybdenum and 0.18g/t gold (copper equivalent 0.46%) containing 6.1 billion pounds copper, 383 million pounds molybdenum and 5.8 million ounces gold,
4. The Inferred mineral resource for the Schaft Creek deposit (at a 0.20% copper equivalent cut-off) totals a further 283.6 million tonnes grading 0.24% copper, 0.011% molybdenum and 0.15 g/t gold (copper equivalent 0.39%) containing 1.5 billion pounds copper, 69 million pounds molybdenum and 1.3 million ounces gold,
5. The silver grade of the Schaft Creek deposit is estimated to range between 1 and 2 g/t. The silver content of the deposit has not been included in the resource estimate due to legacy data issues, and
6. This resource estimate reports significantly higher average copper grade in the Measured mineral resource (0.36%) category, the Indicated mineral category (0.27%) and the Inferred mineral resource (0.24%) category compared to the Measured mineral resource category (0.30%), the Indicated mineral category (0.23%) and Inferred mineral resource category (0.14%) set out in the preliminary feasibility study on the Schaft Creek deposit dated September 2008.

Elmer B. Stewart President and CEO of Copper Fox stated, "The completion of the resource estimate is a great milestone for Copper Fox. Our primary objective now is to complete the feasibility study for the Schaft Creek project as soon as possible. The strategy for the resource estimate was to eliminate areas of very low grade mineralization and therefore reduce grade smoothing. The updated resource estimate shows that the average metal grades for the deposit remain relatively constant up to a 0.25% copper equivalent cut-off, above which the tonnes decrease significantly with a corresponding increase in the average metal grades. The 2011 drilling program is focusing on the higher-grade mineralization intersected in the Paramount zone in 2010 with the objective of defining a higher-grade "starter pit" and increasing the tonnage and average grade of the metals in this zone. Copper Fox expects to complete a resource estimate update for this zone after completion of the 2011 drilling program."

Base Case:
Copper Fox has selected the 0.20% copper equivalent ("Cu Eq.") cut-off for its base case resource estimate.  A 0.12% Cu Eq. cut-off was the minimum grade of copper equivalent estimated by AMEC required (using the estimated copper recovery rate, the milling and sales cost) to break-even on an operating cost per tonne basis.  In adopting a more conservative approach to optimize the economics, Copper Fox has selected a higher cut-off grade to increase the average copper grade per tonne while reducing tonnage.

Resource Estimate:
The effective date of the mineral resource estimate is May 1, 2011. Mineral resources were estimated for the Liard (also referred to as the Main) Zone and the Paramount (also referred to as the Paramount-Breccia) Zone separately.  The mineral resources were estimated using criteria consistent with the CIM Definition Standards (2010) and in conformity with CIM "Estimation of Mineral Resources and Mineral Reserves Best Practice" (2003) guidelines. The estimated mineral resources (Table-1) using a 0.20% Cu Eq. cut-off grade were categorized and tabulated within an economic resource pit shell based on operating costs and metal prices shown in Table-3 and Table-4.

Table-1: Mineral Resource Estimate - Schaft Creek Deposit (David Thomas P. Geo., Effective Date: May 1, 2011

 *The copper equivalent ("Cu Eq.") cut-off calculation is based on metal prices of 1,200 US$/oz gold, 2.90 US$/lb of copper and 15.95 US$/lb of molybdenum, a mining cost of $1.35 US$/t mined and a processing cost of 5.12 US$/t milled. The Mineral Resource is reported at a cut-off grade of 0.20 % Cu Eq. contained within a Lerchs-Grossman resource pit shell optimized on copper, gold and molybdenum grades. The contained metal figures shown are in situ. All figures have been rounded to reflect accuracy and to comply with securities regulatory requirements following "best practice principles".  AMEC undertook quality assurance and quality control studies on the mineral resource data and concludes that the collar, survey, assay and lithology data are adequate to support resource estimation.

Resource Estimation Methodology:
A total of 387 drill holes (approximately 88,685 metres) were used by AMEC in estimating the mineral resources for the Schaft Creek deposit.

The impact of the high-grade samples on the resource estimate for the Schaft Creek deposit was completed using uncapped and capped grade models. The capping grade thresholds and the estimated percentage of metal removed from the resource estimate are shown below in Table-2.

Table-2: Cap Grade Thresholds and Estimated Metal Removed

The procedures used for the purposes of the resource estimate (at a 0.12% Cu Eq. cut-off) are:

1. Sample assays were composited to fifteen metre intervals for grade interpolation.
2. Grade shell solids using 0.1% copper and 0.01% molybdenum cut-off grades were chosen based on the estimated economic cut-off of 0.12% Cu Eq. Polygons were digitised on 50 and 100 m spaced east-west sections linked together from section to section to form solids and then reconciled on a second set of orthogonal sections.
3. Grade shells developed for the Schaft Creek deposit defined two broad domains, namely the Main (Liard) zone and the Breccia (Paramount) zone. The Main zone has a bowl shaped geometry, whereas the Breccia zone has a tabular elongate sub-vertical geometry.
4. Where gold assays were missing from the database, gold values were assigned to these intervals using a linear regression analysis against copper grades.
5. No significant statistical differences exist in copper, gold and molybdenum grades between lithological rock types within the Main zone. Significant differences exist between the metal grades of the rock types present in the Breccia zone. Validation of the grade estimates shows no global or local bias. Some over smoothing in the kriged model is observed.
6. The legacy data corrections and regressions do not have a significant impact on the estimation of copper, molybdenum and gold grades.
7. The drill hole spacings for blocks in the Measured and Indicated categories were based on confidence limits of copper, gold and molybdenum grades determined by kriging for the Liard (Main) zone and the Paramount (Breccia) zone separately. Blocks included in the Measured category required three drill holes within a 70 metre radius and Indicated blocks required at least two drill holes within a 135 metre radius. Blocks in the Measured category required that more than two thirds of the ordinary kriging weight used in grade interpolation came from the higher confidence Copper Fox drill holes. Extrapolation of Inferred resource blocks is restricted to the limits of the copper grade shells.
8. A total of 2,784 specific gravity determinations were used to assign a constant specific gravity value of 2.69 g/cm3 to all lithological rock types. A constant value of 1.8 g/cm3 was assigned to all overburden material.
9. The estimated copper, gold and molybdenum grades were determined using ordinary kriging using multiple estimation passes with incrementally increasing search distances. In the Main zone, five separate subdomains were used to split the bowl shape into volumes with an approximately consistent orientation.

Resource Statement:
For constraining the blocks to be reported as mineral resources, an economic resource pit shell was developed using a Lerchs-Grossman resource pit shell optimized on copper, gold and molybdenum grades based on the parameters listed in Table-3.  Metal prices used to determine the pit shell were copper (US$2.90/lb), gold (US$1,200/oz) and molybdenum (US$15.95/lb).

AMEC's marginal cut-off value of 0.12% Cu Eq. was determined based on the parameters set out in Table-4.

The copper equivalent formula is derived below:

Cu Eq (%) = Cu (%) + Mo (%) x Mo factor + Au (g/t) x Au factor where:

Table 4: Copper Equivalent Cut-off Calculation Parameters

The sensitivity of the mineral resource in the Schaft Creek deposit (includes the Liard and Paramount zones) to either a reduction or increase in copper equivalent cut-off is shown in Table-5. The base case mineral resource above a 0.20% Cu Eq. cut-off is reported separately within the Paramount zone (in Table-6) and within the Liard zone (in Table-7).

Table-6: Mineral Resource Reported within the Paramount Zone (at 0.20% Cu Eq. cut-off)

Table-7: Mineral Resource Reported within the Main Zone (Liard) at 0.20% Cu Eq. cut-off

AMEC determined that the silver should not be reported as a part of the mineral resource estimate due to data quality issues which preclude the classification of Measured and Indicated resources including silver. The silver grades within the Schaft Creek deposit range between 1 g/t and 2 g/t.
