Copper North Mining Corp. is pleased to provide an overview of exploration on the Carmacks Project.
The Carmacks copper-gold-silver mineralization has been found in at least 15 zones, defining the mineralized northeast dipping shear structures that extend for at least five kilometres. The proposed mining area consists of zones 1, 7, 7a and 4, spanning approximately 600 metres of the main structure. The 2014 program consisted of geologic mapping, trenching, induced polarization and magnetic geophysical survey and diamond drilling and focused on expansion of the proposed mining area. The mineral resources contained in the proposed mining area are 11.98M tonnes of Measured and Indicated resources grading 1.07% copper, 0.456 g/t gold and 4.58 g/t silver. The mineralization appears to be cutoff by northeast trending cross faults.
Dr. Harlan Meade states: "The 2014 program, composed of geological review and target priority for expansion of mineral resources adjacent to the proposed mining area at Carmacks, confirmed the opportunity for significant expansion of both oxide and sulphide mineral resources. A larger program is being planned for 2015 with the goal to expand the mineral resources in pursuit of extending the potential mine life."
South GAP Zone - 2000S Extension
This zone is located between the south extension of zones, 1, 7, 7A and 4 and 2000S zone. The South Gap target consists of an approximate 300 metre gap between the main proposed mining area and the 2000S zone. The 2000S zone has been defined by 6 drill holes with both oxide and sulphide mineralization. Drill hole WC92-01 intersected 10.67m grading 0.67% copper at a depth of 30 to 41metres. To follow up on this intercept, drill hole CN14-11 was collared 22 metres to the north northwest of WC92-01, and intersected 18.74 metres grading 0.58% copper, 0.189 g/t gold and 2.46 g/t silver at a depth 21 to 40 metres. Three other drill holes failed to intercept the mineralized zone. Additional drilling is warranted in defining the continuation of the mineralization to the northwest and location of the cross faults that are displacing the mineralization in the GAP zone. Any expansion of the 2000S zone has the potential to define a mineral resource amenable to open pit mining, and could coalesce with the main proposed pit area.
North GAP - Zone 2 Extension
The North Gap represents the area between the boundary fault that truncates the north end of Zone 1 and Zone 2; a distance of approximately 2,500 metres. Exploration this past year was focused on extending the Zone 2 mineralization along strike. Trenching indicated that Zone 2 is cutoff by a cross fault, approximately 20 metres to the northeast of the discovery outcrop and trench. Additional trenching failed to find an extension on the north side of the cross fault. Trenching to the southeast met with success.
The historic Zone 2 trench was refreshed with the excavator and the oxide copper zone was resampled. The shear fabric and distribution of oxide copper minerals indicates a steep dipping mineralized zone, trending southeast; sampling yielded 15 metres grading 0.9% copper oxide mineralization. Trenching to the southeast was successful in tracking the mineralized zone for approximately 500 metres. Sampling of mineralization was hampered by permafrost capping that limited the downslope extent. Sampling of the oxide copper mineralization in the new trenches varied from 3m grading 0.43% copper to 12 metres grading 1.05% copper.
To test the mineralization to depth, ten drill holes were undertaken and defined the mineralized structure over a distance of 450 metres. The drill holes intersected the mineral zone at depths between 9.6 metres and 81.0 metres. All holes intercepted the mineral zone and yielded an average of 10.5 metres grading a weighted average of 0.36% copper, 0.069 g/t gold and 4.37 g/t silver. The intercepts and grade of the individual intercepts is available on the Company's web site.
The trenching and drill hole intercepts in Zone 2 confirm the continuity of the mineralization to the south. Additional exploration is warranted to determine if the Zone 2 mineralization is an extension of Zone 1. Of interest, part of the target area is covered by near flat lying Cretaceous volcanic rocks, which may well provide an erosional cover that may preserve the oxidized mineralization. The preservation of oxide mineralization to depth is key to developing additional substantial oxide copper resources.
The target area between the most southerly intercept and the boundary fault is approximately 2,000 metres long, the North Gap Zone, is the prime focus for drilling in 2015. The 2015 program will also include detailed geophysical surveys to define structural features hosting and displacing mineralization.
Drill, trench and soil samples were analyzed by ALS Ltd, in Vancouver, BC. Duplicate samples of drill core were collected at 20 sample intervals and analyzed by Acme Analytical Laboratories Ltd. Sample Standards and sample blanks were inserted with each sample shipment, with each of the laboratories.
