Having confirmed continuity of both oxide and sulphide mineralization in 2000s, drilling has started to shift to define the much larger Zones 13 and 12 areas

After starting drilling last July at its Carmacks Project in the Yukon, Copper North Mining (CVE:COL) has completed eight drill holes in the 2000S Zone, identifying new mineral resources of oxide and sulphide mineralization.

The current drill program aims to expand oxide and sulphide mineral resources and is focusing on the southern extension of the proposed open pit area. The plan has set an initial target of expanding oxide mineral resources by approximately 4 million tonnes and a greater amount of sulphide mineralization.

The 2000S zone that forms part of the Gap South target area immediately south of the proposed open pit area. Previous drilling has defined a near surface oxide and sulphide mineral zone.  New and historic drill holes have defined a wedge shaped zone with a strike length of 300 meters and up to 150 meters vertically while the indicated tonnage potential has been estimated at about 1.1 million tonnes, 300,000 tonnes of which being oxide mineralization.          

Having confirmed continuity of both oxide and sulphide mineralization in 2000s, drilling has started to shift to define the much larger Zones 13 and 12 areas that have an aggregate strike length of 1500 meters, which, according to Copper North, have “potential for a substantial addition to mineral resources”.

Previous drilling at zones 13 and 12, located on the south side of Williams Creek and approximately 150 meters to the south of Zone 2000S, identified up to 70 metres vertical depth of oxide mineralization overlying sulphide mineralization with intercepts up to 200 meters in depth.

The present drill campaign, at zones 13 and 12, is targeting near surface mineralization to a depth of 150 meters and includes both oxide and sulphide mineralization. Historic drilling in this 150 to 200 meter section of the mineralization has suggested a potential of 2.8 million tonnes of oxide and approximately 6.8 million tonnes of sulphide mineralization.

As for the continuation of Zone 1 to the north of the proposed open pit, the Gap North area, the company has decided to defer the planned drilling because of the presence of excessive overburden and valley fill materials while Zones 2000s, 13 and 12 present greater potential near surface. A mineral resource inventory for Zones 2000S, 13 and 12 will be undertaken when all drill and trench results are received.

Measured and Indicated mineral resource estimate totals 11.98 million tonnes grading 1.07% total copper, of which 0.86% is soluble copper according to a preliminary economic assessment filed on SEDAR on May 30, 2014, which also contains substantial gold and silver.   

According to the PEA, the project is expected to produce some 30 million pounds of LME ‘Grade A’ copper cathode per year, as well as 17,300 ounces of gold and 165,000 ounces of silver.
