CUU own 25% Schaft Creek: proven/probable min. reserves/940.8m tonnes = 0.27% copper, 0.19 g/t gold, 0.018% moly and 1.72 g/t silver containing: 5.6b lbs copper, 5.8m ounces gold, 363.5m lbs moly and 51.7m ounces silver; (Recoverable CuEq 0.46%)
Vancouver, British Columbia - November 15, 2011- Copper Fox Metals Inc. (TSX-Venture: CUU) is pleased to announce additional assay results for two diamond drill holes completed in the Paramount zone of the Schaft Creek copper-gold-molybdenum-silver deposit. An update on diamond drilling and geotechnical activities related to open pit slope design for the feasibility study is also presented. We also advise that two diamond drills are currently working at Schaft Creek to test the northern extension of the copper-gold-molybdenum-silver mineralization in the Main zone and to sterilize areas around the deposit designated for waste storage. To view the location of 2011 drill holes completed to date, visit the Copper Fox website atwww.copperfoxmetals.com. Highlights of the drilling activities are: Mr. Stewart, President of Copper Fox stated, "We are very pleased to report that the 2011 drill results continue to expand the limits of the higher-grade mineralization with all drill holes containing significantly higher metal and copper equivalent grades than reported in the updated resource estimate for the Paramount zone. Diamond drill holes CF411-2011 and CF412B-2011 have intersected multiple thick zones of higher-grade and extended mineralization to the east, west and at depth".Copper Fox Metals - Drilling Intersects 0.91% Copper Equivalent over 387M at Schaft Creek

Diamond Drilling Analytical Results:
The weighted average grades for DDH CF411-2011 and CF412B-2011 were estimated using a zero cutoff grade, see table below. A high-grade silver assay in DDH CF411-2011 (assayed 1,689 g/t silver (54.3 ozs) over 3.0m) was cut from 1,689 g/t to 31.1 g/t for purposes of estimating the weighted average grade of the silver in the mineralized interval in this drill hole.
DDH CF411-2011was drilled to a total depth of 745.5m. The mineralization commences at a core length of 155.1m and continues to the end of the hole at 745.5m. The last sample in this hole returned 0.72% copper equivalent mineralization. Disseminated and fracture/veinlet controlled chalcopyrite, bornite and molybdenite occur in potassic and phyllic altered Intrusive Breccia and Granodiorite. The interval from 206.0 to 209.0 (core recovery of less than 20%) assayed 1,689 g/t silver (54.3 ozs). The upper 155.1m of this hole was not mineralized as expected based on the morphology of the mineralized zone. This drill hole has extended the mineralization at depth an additional 175m.

Note: The core intervals listed in the above table do not represent true widths.
DDH CF412B-2011 was drilled to a depth of 636.1m. The mineralization commenced at a core length of 6.58m and continues to the bottom of the hole at 636.1m. Chalcopyrite, bornite and molybdenite occur as disseminations and as fracture/veinlet filling in potassic, phyllic and biotite altered brecciated Granodiorite, Andesite and polylithic Intrusive Breccia. This hole was stopped in 0.45% copper equivalent mineralization. This hole has extended the mineralization an additional 85m to the east and 65m below the mineralization intersected at the bottom of DDH CF402-2010. This hole contains two intervals of higher grade mineralization with the upper interval containing higher grades of molybdenite and the lower interval higher gold grades.
2011 Diamond Drilling Summary:
The 2011 diamond drilling summary is set out below. Several holes were terminated due to difficult ground conditions. DDH CF425-2011 is the last hole for the 2011 field season. The assay results for DDH CF407-2011 through DDH CF412B-2011 have been reported. The assays for the remainder will be reported when received.

Diamond Drilling and Sampling Procedures:
The diamond drilling was completed using a HQ and NQ core size. Overall core recovery was estimated to be greater than 98%. After cutting with a diamond saw, one half of the core is collected for sample preparation and analysis and the other half retained for future reference. Sample intervals were selected based on lithology changes/alteration intensity/estimated mineral content and ranged from 0.73 to 3.10 metres. The majority of the sample intervals were 2.0m. Sample preparation was completed by ACME Analytical Laboratories Ltd ("ACME") located in Smithers, British Columbia and analyses were completed by ACME in Vancouver, British Columbia.
Base metals were assayed using the ACME's 7TD package which includes 4-acid digestion and ICP-ES finish. Lower detection limits are as follows: Cu >0.001%, Mo >0.001%, Silver values are determined by the 1EX with a lower detection limit of 0.1g/t. Gold is assayed by the G6 fire assay package - fusion of a 30-gram followed by ICP-ES finish; with a lower detection limit of 0.005 g/t. ACME has an 9001:2008 International Standard Organization rating.
Recoverable copper equivalent calculations are based on 88% of the copper content plus 81% of the gold content, 72% of the molybdenum content and 71% of the silver content. Metal prices are copper $US2.50/pound, gold $US1,075/ounce, molybdenum $US17.00/pound and silver $US16.10/ounce.
Quality Control
Copper Fox follows a rigorous Quality Assurance/Quality Control program consisting of inserting standards, blanks and duplicates into the sample stream submitted to the laboratory for analysis.
