COPPER FOX ANNOUNCES VAN DYKE DRILL RESULTS AND PROVIDES OTHER PROJECT UPDATES
Copper Fox Metals Inc. and its wholly owned subsidiaries Desert Fox Copper Inc. and Northern Fox Copper Inc. have provided updates on the Schaft Creek joint venture with Teck Resources Ltd., analytical results for the last three drill holes from the verification drilling program on the Van Dyke oxide copper deposit and the results of the Quantec Titan-24 DCIP survey on the Eaglehead copper project competed by Carmax Mining Corp. Northern Fox owns 42.09% of the shares of Carmax.
Highlights: -- At Schaft Creek, the 2014 mapping outcrop and core re-logging program to collect information for pit slope stability as part of the ongoing optimization work was completed at the end of August, -- At the Van Dyke copper project, all three drill holes returned significant concentrations of copper mineralization over broad intervals including 2.09% total copper over a 31 foot (9.5 metre ('m')) interval in DDH VD14-06, -- At the Eaglehead copper project; the Quantec Titan 24 survey outlined a large chargeability anomaly consisting of two distinct chargeability signatures over a 5,600m long horizontal distance, -- The first signature at the Eaglehead project (greater than 20 mRad chargeability signature) ranges from 500m to 1,000m wide, is open at depth below the -550m level and is surrounded by a broad greater than 10mRad chargeability signature from Line 1 to Line 8 (horizontal distance of 4,500m) and covers four of the six zones of mineralization identified to date. This chargeability signature is open to the northwest towards the West zone, -- The copper mineralization reported at the Eaglehead project in the historical (where sampled) and current drill holes in the Pass, Camp, Bornite and East zones of mineralization, (horizontal distance of 3,000m) either on or in proximity to the geophysical survey lines, shows a good correlation to the greater than 10 mRad chargeability signature, and -- The second signature at the Eaglehead project occurs on Line-9 and Line- 10 (horizontal distance 1,100m) is a distinct greater than 10 mRads chargeability signature that is approximately 1,000m wide and is open at depth below the -550m level. This chargeability signature has not been drill tested and is open to the southeast towards the Far East zone.
Mr. Stewart, President of Copper Fox stated, "August has been a busy month for Copper Fox. The assay results for the last three holes from the Van Dyke project has yielded good copper grades over significant intervals as well as one interval of high grade copper mineralization. These assay results have been transferred to Moose Mountain Technical Services for review with the objective of commencing a resource estimation in September. Now that the summer field program at Schaft Creek has been completed the results can be incorporated into the 2014 optimization work currently underway on the Schaft Creek Joint Venture. The geophysical work on the Eaglehead copper project has outlined a large, strong positive chargeability anomaly that exhibits an excellent correlation with the historical and current assay results over a 4.5 km long horizontal distance."
Van Dyke Project:
The Globe-Miami District hosts the Pinto Valley, Carlota, Miami-East and Miami-Inspiration copper projects (all currently producing copper mines) and the mined out Copper Cities and Old Dominion copper deposits. The Van Dyke oxide copper deposit is located immediately adjacent to the Miami-East and Miami-Inspiration operations (see the Company's news release dated April 12, 2013 for further detail with respect to the historical work completed on the Van Dyke oxide copper deposit).
Diamond Drilling Results:
The weighted average grades for the three diamond drill holes were estimated using a 0.05% copper cutoff; in line with the cutoff grade used in other in-situ recoverable copper deposits currently under evaluation in Arizona. The correlation of the analytical results for the verification drilling program with the historical analytical results is expected to be completed in September at which point a decision on the resource estimate will be made. The below table shows the total copper and soluble copper concentrations in the core samples. The total soluble copper concentration is the total amount of copper that could be recovered utilizing solutions.
All three drill holes included in this news release returned significant intervals of total copper mineralization with a very high percentage of soluble copper. Analyses for other metals present returned low concentrations.
Results for the mineralized intervals in the last three holes at the Van Dyke project are tabulated below:
Total Total/ Total Soluble Soluble DDH Zone Azimuth Dip From To Interval Copper Copper Copper ID (m) (m) (m) (%) (%) (%) VD14-04 Oxide 0 90 452.4 596.6 144.2 0.38 0.33 86.8 VD14-05 Oxide 0 90 401.4 450.6 49.2 0.56 0.52 92.9 VD14-06 Oxide 0 90 249.1 383.8 134.8 0.33 0.24 72.7 Including 268.0 277.4 9.5 2.09 1.94 92.8 Core interval does not represent true thickness of the mineralized zone
Sampling Procedures:
Sample preparation and analytical work was completed by Skyline Assayers & Laboratories located in Tucson, Arizona. The sequential copper analysis uses a 0.25 gram sample digested (at room temperature) in 5% sulfuric acid and the solution is then diluted to 100 mL with deionized water. The residue from the sample is digested in 10% sodium cyanide solution and diluted to 100 mL. The samples are placed in a lateral shaking machine as follows: i) 5% H2SO4 for one hour; and ii) 10% NaCN for thirty minutes.
The gold and silver analyses were completed using Skyline's FA-1 and FA-8 analytical procedures. The other base metals such as molybdenum, lead and zinc were analyzed utilizing a 20 gram sample and Skyline's TE-2 procedure and a three acid digestion followed by ICP/OES finish. Skyline is independent of Copper Fox and has a 17025-2005 International Standard Organization rating.
Quality Control:
Desert Fox follows a rigorous Quality Assurance/Quality Control program consisting of inserting standards, blanks and duplicates at regular intervals into the sample stream submitted to the laboratory for analysis.
