Copper North Announces Results from Drilling at Carmacks Project
Vancouver, British Columbia -- Copper North Mining Corp. ("Copper North" or the "Company") (TSX.V:COL) is pleased to announce results from the first 8 drill holes of the 22 drill hole program of approximately 2,500 metres at the Carmacks copper-gold project, Yukon. The fill-in drill holes are focused on the previously known mineral zones that have a length of 2,000 metres. The first eight drill holes in the 2000S structural zone intersected oxide and sulphide copper mineralization. The detailed drilling has confirmed the continuity and quality of these zones and the potential for expansion of mineral resources at Carmacks.
Zones 2000S and 13 are outside of the proposed open pit area and drilling has been focused on these zones with the objective of expanding the resource beyond the Measured and Indicated resource of 11,980,000 tonnes grading 1.07 % total copper, 0.86% acid-soluble copper in Zones 1, 4, 7 and 7A (see Preliminary Economic Assessment filed on SEDAR on May 30, 2014, the "PEA").
Zone 2000S is located 400 metres south of the edge of the proposed open-pit. In addition to eight diamond drill holes in 2015, five historic holes from 2007 and 2014 define the mineralized zone. The drill density should now be sufficient to define a mineral resource. The drill hole locations, plan maps and cross-sections for Zone 2000S are available on Copper North's website, www.coppernorthmining.com.
Table 1 - Drilling results from Zone 2000S.
The highlights of the drilling include an estimated true width of 18.32 metres of oxide mineralization grading 0.72% total copper, 0.47% soluble copper in hole CN15-02, and an estimated true width of 24.01 metres of sulphide mineralization grading 1.01% total copper from hole CN15-07.
Zone 2000S extends along strike for approximately 300 metres, and is open to the south and has a variable width: the zone widens to the south and widens with depth. The average vertical thickness of the oxide zone is approximately 95 metres and the sulphide zone is open to depth.
The tonnage potential for Zone 2000S has been estimated using 3D wireframes and geometrical methods, assuming a density of 2.7 tonnes/cubic metre and extending to depths of 160 to 190 metres below surface. The current density of drilling supports an estimate of between 1.6 and 1.8 million tonnes of mineralization comprising approximately 50% oxide mineralization and 50% sulphide mineralization. A further ~500 metres of drilling may increase the tonnage potential to as much as 2.4 million tonnes.
Investors are cautioned that the tonnage potentials indicated here are not NI43-101 compliant resources or reserves. Tonnage potentials were calculated based on volumes of rock derived from the geological interpretation between drill intercepts that contain visible copper mineralization. No statement is made regarding the potential grade of the tonnage potentials.
Copper North is awaiting assays for the remaining 14 holes that were drilled in Zone 13.
Fourteen holes were drilled in Zone 13, which lies to the south of the Williams Creek valley, approximately 300 metres south-east of Zone 2000S (see August 4, 2015 news release). Zone 13 is approximately 650 metres long, but the drilling in 2015 has focused on an approximately 300 metre long section of strike where the widest and thickest amount of near-surface oxide copper mineralization is evident. Thirteen of fourteen holes intersected oxide copper, native copper or copper sulphide mineralization. The fourteenth hole was lost due to poor ground conditions. Including historic drill holes, there are now 30 drill holes in Zone 13 that have intersected copper mineralization. The drill density should now be sufficient to define a mineral resource once assay results have been received. Zone 13 is open to the north, to the south and at depth.
Quality assurance and quality control procedures include the systematic insertion of duplicate and standard samples in to the sample stream. Drill core samples were sawn in half, labelled, placed in sealed bags and were shipped directly to the preparatory laboratory of ALS Minerals in Whitehorse. All geochemical analyses were performed by ALS Minerals in North Vancouver. Total copper assays were performed by four-acid digestion with an AAS finish. Soluble copper assays were carried out by sulphuric acid digestion with an AAS finish. Gold was analyzed by a 30 g charge fire assay with an AAS finish. Silver was analyzed by four-acid digestion and ICP-AES finish.
