Copper Fox announces drilling intersect of 0.96% CuEq over 110m and reports metallurgical testwork results
Feb 03, 2012, 10:32 ET
VANCOUVER, Feb. 3, 2012 /CNW/ - Copper Fox Metals Inc. (TSX-Venture: CUU) is pleased to announce further assay results from four diamond drill holes completed for geotechnical purposes as part of the 2011 drill program and recently completed metallurgical testwork on the Paramount zone of the Schaft Creek deposit. The locations of 2011 drill holes can be viewed on the Copper Fox website at www.copperfoxmetals.com. Highlights are:
- Diamond drill hole (DDH) CF419-2011 located in the Liard zone intersected 0.46% copper, 0.41g/t gold, 0.043% molybdenum and 2.15g/t silver (0.96% copper equivalent) over an interval of 110.8m starting at a core length of 10.2m,
- DDH CF419-2011 also intersected 0.55% copper, 0.20g/t gold, 0.013% molybdenum and 1.88g/t silver (0.76% copper equivalent) over an interval of 136.7m starting at a core length of 121.0m,
- DDH CF417-2011 intersected 0.24% copper, 0.08g/t gold and 1.27g/t silver over a 21m interval starting a core length of 399.0m,
- DDH CF423-2011 located 650m west of the Liard zone of the Schaft Creek deposit intersected three significant intervals of copper-silver mineralization, and
- Metallurgical testwork on composite samples of the mineralization from the Paramount zone has yielded an average recovery of 89% for copper, 64% for molybdenum, 73% for gold and 58% for silver to a bulk concentrate grading between 31 and 32% copper.
Mr. Stewart, President of Copper Fox stated, "DDH CF419-2011 was drilled for geotechnical purposes in one of the proposed starter pits and intersected significant intervals of higher grade copper mineralization and of note, higher gold and molybdenum values closer to surface. The geotechnical holes DDH CF417-2011 and DDH CF423-2011 have intersected significant intervals of copper mineralization a considerable distance outside the current limits of the Schaft Creek deposit which suggests a considerable amount of additional drilling is required to define the outer limits of the Schaft Creek deposit. Upon receipt of the assay results from the remaining seven diamond drill holes of the 2011 program, expected shortly, the Company will initiate the preparation of an updated "Resource Estimate" to include the results of the 2011 program. The metallurgical test work results for the Paramount zone are very encouraging, showing a high percentage recovery for the various metals including silver."
Diamond Drilling Analytical Results
Three of the four geotechnical drill holes intersected significant copper mineralization. The weighted average grade for the mineralized intervals was estimated using a zero cutoff grade, see table below.
|DDH ID||Dip||Azimuth||From (m)||To (m)||Interval (m)||copper (%)||gold (g/t)||silver (g/t)||molybdenum (%)||Cu Eq (%)|
DDH CF419-2011: was completed for geotechnical purposes at the south end of the proposed Liard zone starter pit and intersected continuous mineralization starting at a core length of 10.2m to a depth of 257.7m where the mineralization is cut off by a flat lying mylonitic fault zone. Assays of samples from below the mylonite zone yielded background concentrations of all metals. Disseminated and fracture/veinlet controlled chalcopyrite, bornite and molybdenite occur in potassic and phyllic altered andesite. The upper 110.2m of the hole contains significantly higher concentrations of molybdenum and gold.
DDH CF417-2011: was drilled for geotechnical purposes approximately 300m east of the Paramount zone to obtain information for pit slope design purposes. This hole intersected two significant intervals of copper mineralization in andesite. The first interval commences at a core length of 226.0m, is 16m long and contained anomalous concentrations of copper (from 0.01% to 0.13%), gold (0.01 to 0.043 g/t) and silver (0.1 to 0.9 g/t). The second interval is 21m long and contained individual samples of up to 1.9% copper, 0.66g/t gold, 15.6g/t silver and 0.065% molybdenum. These mineralized intervals are interpreted to represent either "leakage zones" from a deeper source or a separate mineralizing event.
DDH CF416-2011: was drilled for geotechnical purposes east of the Paramount zone to obtain information for pit slope design purposes. This hole intersected a 13.8m core length interval starting at 252.1m with significant, anomalous concentrations of copper (from 0.01% to 0.036%), gold (0.014 to 0.164 g/t) and silver (0.1 to 0.8 g/t). Five other narrow intervals of anomalous (> 0.01%) copper concentrations occur throughout this hole.
DDH CF423-2011: was completed for geotechnical purposes approximately 650m west of the Liard zone to test a coincident chargeability anomaly outlined in 2011 and copper mineralization intersected in DDH HAS16 (see news release dated October 17, 2011). The mineralization in this hole is mainly copper-silver with low concentrations of gold and molybdenum which suggest that this mineralization is different from that in the Liard and Paramount zones. The mineralization in this hole is open along strike and at depth.
Metallurgical test work including; rougher flotation, locked cycle testing by closed circuit flotation and concentrate quality was completed on six samples of mineralization from the Paramount zone. The test work was completed by G&T Metallurgical Services Ltd. Six samples (totaling 810 kgs) were tested for metallurgical performance. These samples were prepared using 80% passing 150 micron grind size, tested individually and then composited for similar test work. Results of the test work on the two master composite samples (with average copper grades of 0.42% copper) yielded average recoveries of 89% copper, 64% molybdenum, 73% gold and 58% silver. Concentrate produced from this testwork averaged 31% copper, 1.30% molybdenum, 16 g/t gold and 131 g/t silver. The concentrate was low in other base metals and other common penalty elements. These results will be combined with the previous metallurgical test work from the Schaft Creek deposit to determine the estimated average metal recoveries to be used in the feasibility study that is expected to be completed in the first quarter of 2012.
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 with a diamond saw, 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 3.00 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 $US1,075.00/ounce, molybdenum $US17.00/pound and silver $US16.10/ounce.
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.
