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, Feb. 16, 2012 /CNW/ - Copper Fox Metals Inc. (TSX-Venture: CUU) is pleased to announce the balance of the assay results from the 2011 diamond drilling program completed on the Schaft Creek deposit. The locations of 2011 drill holes are shown on the Copper Fox website at www.copperfoxmetals.com. Highlights are:
Mr. Stewart, President of Copper Fox stated, "The interpretation that the Schaft Creek Mineral Resource could host other deposits is strongly supported by the mineralization in DDHCF422-2011. Although a considerable amount of drilling is required to delineate and determine the significance of this discovery, the continuity of the mineralization and its location on the western edge of a large strong chargeability anomaly suggests that this zone has considerable potential. This discovery marks a significant milestone in understanding the mineral potential of the Schaft Creek project. DDHCF418B, DDHCF420-2011 and DDHCF425-2011 were drilled between the Paramount and Liard zones and demonstrate continuity of the mineralization along strike and at depth. These holes contain higher grade intervals which although narrowing to the south are hosted in broad zones of copper mineralization with lower gold and molybdenum concentrations."
Diamond Drilling Analytical Results:
The weighted average grade for the mineralized intervals was estimated using a zero cutoff grade. Internal intervals that exceed 20 metres in length are excluded from the weighted average calculation, see table below. DDH418-2011 was terminated due to drilling difficulties. DDH418B-2011 is located at the same collar as DDH418-2011

Mineralized intervals included in the above table do not represent true thickness
DDH CF418B-2011: was completed to test the continuity of the mineralization in an area between the Paramount and Liard zones where very little information previously existed. This hole intersected a significant zone of higher-grade mineralization below DDHCF403-2010 (see News Release dated February 13, 2011). Disseminated and fracture/veinlet controlled chalcopyrite, bornite and molybdenite occur in phyllic altered polylithic breccia and andesite. The significant interval of higher grade gold-silver mineralization at the bottom of this hole appears to represent a new style of mineralization that was not previously intersected in the 2010 and 2011 drilling programs.
DDH CF420-2011: was also completed to test the continuity of the mineralization in an area between the Paramount and Liard zones. This hole intersected a broad zone of copper mineralization which includes a 127.0m interval of higher-grade mineralization. Disseminated and fracture/veinlet controlled chalcopyrite, bornite and molybdenite occur in phyllic altered andesite including an interval of higher grade gold-silver mineralization in the interval from 527.0m to 654.0m.
DDH CF425-2011: was also completed to test the continuity of the mineralization in an area between the Paramount and Liard zones. This hole intersected two significant intervals of mineralization in phyllic altered andesite and tourmaline breccia. The 52m interval between the mineralized intervals reported in the above table contained low grade (<0.10%) copper values hosted in andesite. The extent of the mineralization in this hole to the west has been delineated.
DDH CF422-2011: is located approximately 1,200m north of the Paramount Zone and was drilled for geotechnical/exploration purposes. This hole intersected copper-molybdenum mineralization at a core interval of 83m and remained in a similar style mineralization to the bottom of the hole at 318m. The mineralization shows a strong correlation to the outer edge (and weaker chargeability) of a large (1,800m by 800m) Titan-24 chargeability anomaly, the strongest portion of which occurs east of the drill hole collar location and remains untested by drilling.
DDH CF421-2011: was drilled for geotechnical purposes south of the Liard zone to sterilize this area for waste dump planning for the feasibility study. This hole intersected several narrow (less than 4m apparent thickness) of low grade (0.10% to 0.15%) copper mineralization.
DDH CF424-2011: was completed to test the continuity of the mineralization intersected in DDHCF423-2011 (see News Release dated January 13, 2012). This hole intersected one significant interval of mineralization that appears to correlate with the mineralization in DDHCF423-2011.
Diamond Drilling and Sampling Procedures:
The diamond drilling was completed using an HQ and NQ core size. Overall core recovery was estimated to be greater than 99%. After cutting, one half of the core is collected for sample preparation and analysis and the other half is retained for future reference. Sample intervals were selected based on lithology changes/alteration intensity/estimated mineral content and ranged from 0.90 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% for copper plus 81% for gold, 72% for molybdenum and 71% for silver. Metal prices are copper $US2.50/pound, gold $US1,075.00/ounce, molybdenum $US17.00/pound and silver $US16.10/ounce. Copper Fox is using these input data to allow the reader to relate the average grades of the mineralized intervals reported in 2010 and in 2011.
