Copper North Drilling Expands Copper Mineralization at Carmacks Project, Yukon
VANCOUVER, BRITISH COLUMBIA--(Marketwired - Aug 4, 2015) - Copper North Mining Corp. ("Copper North" or the "Company") (TSX VENTURE:COL) has completed eight drill holes in the 2000S Zone, at Carmacks Project, to provide the additional information required to estimate new mineral resources of oxide and sulphide mineralization. Previous resource inventories have been limited to the proposed open pit area that consists of Zones 1, 4, 7 and 7a. The 2015 drill program is focused on expansion of oxide and sulphide mineral resources and is focusing on the southern extension of the proposed open pit area.
Initial fill-in drilling at 2000S zone has confirmed continuity of both oxide and sulphide mineralization. The drill has now moved to the much larger Zones 13 and 12 areas that have an aggregate strike length of 1500 meters. The definition drilling has potential for a substantial addition to mineral resources.
2000S Zone
Zone 2000S is immediately south of the proposed open pit area. All eight drill holes intersected the mineralized structure. The new and historic drill holes define a wedge shaped zone with a strike length of 300 meters and up to 150 meters vertically: a tonnage potential of approximately 1,100,000 tonnes is indicated of which about 300,000 tonnes is oxide mineralization.
The drill hole density and trench sampling are sufficient for determination of mineral resources for the 2000S zone; Copper North is awaiting assays. Details of drill hole location and historic assay results are available on Copper North's web site www.coppernorthmining/com.
Zones 13 and 12
Copper North is now drilling in the much larger Zones 13 and 12 which are located on the south side of Williams Creek, approximately 150 meters to the south of Zone 2000S.The target in Zone 13 has a strike length of 650 metres and Zone 12 is the southern extension of Zone 13. Drilling is in progress, with fans of drill holes between the previous 120 meter spaced drill cross sections (4400 and 4800 feet historic drill sections) in Zone 13.
Previous drilling has identified up to 70 metres vertical depth of oxide mineralization overlying sulphide mineralization that has been intercepted to depths of 200 meters and remains open to depth. Current drilling is focused on near surface mineralization to a depth of 150 meters and includes both oxide and sulphide mineralization. Recent trenching and detailed ground magnetic surveys have defined the mineralized structure and identified new zones of oxide mineralization.
Cross-sections of historic drill hole intercepts and location of new and planned drill holes are available on Copper North's web site. Historic drilling in this 150 to 200 meter section of the mineralization indicates potential of 2.8 million tonnes of oxide and approximately 6.8M tonnes of sulphide mineralization. Extension of the mineralization now being drilled has the potential for substantial additional increase of oxide and sulphide mineralization.
Gap North
Copper North previously stated that it would explore for the continuation of Zone 1 to the north of the proposed open pit (July 20, 2015 news release). The Gap North area has extensive overburden and valley fill materials. Drilling in the North Gap area is now being deferred as the Zone 2000S and Zone 13 and 12 have more near surface potential.
Mineral Resources and Expansion Opportunity
The Measured and Indicated mineral resource estimate totals 11,980,000 tonnes grading 1.07% total copper, of which 0.86% is soluble copper (see Preliminary Economic Assessment filed on SEDAR on May 30, 2014, the "PEA"). The mineral resource estimate also contains substantial gold and silver. The resource in the oxide classification forms the basis for the potentially mineable mineralization by open pit methods as described in the PEA.
The current drill plan has established an initial target of expanding oxide mineral resources by approximately 4M tonnes and a greater amount of sulphide mineralization. A mineral resource inventory for Zones 2000S, 13 and 12 will be undertaken when all drill and trench results are received.
