Tungsten Copper Program

Copper North Reports Exploration Program
An exploration program was conducted by Aurora Geosciences Ltd. (a company which was engaged by Copper North to provide geological, geophysical and logistical field services in the Northwest Territories) in 2012, which targeted stratiform, sedimentary rock-hosted, copper-silver mineralization, and included; geological mapping, 21.3 line km of induced polarization ("IP") surveys, 41.25 line km of ground-based extremely low frequency electromagnetic ("ELF-EM") surveys, 324 stream sediment samples and 690 biogeochemical samples. An additional 18,979.1 acres across 15 new mineral claims were staked to increase Copper North's land position in the Redstone Copperbelt.
Highlights include:
Identification of drill-ready targets at the Coates Lake and Johnson Vein properties
Delineation of chargeable IP anomalies at the north end of the Coates Lake property that extend along strike northwards 3,000 m from the limit of known stratiform copper-silver mineralization
Delineation and 3D modelling of a complex zone of chargeable IP anomalies that extends at least 1,000 m along strike at the south end of the Coates Lake property
ELF-EM surveys have been a useful tool to provide new data on structures and stratigraphy in the near and deep (<2 km) subsurface. This data can be used to help target exploration efforts and to de-risk the positioning of future drill holes
Several regional targets have been generated with anomalous stream sediment geochemistry, including samples that have returned assays of up to 490 ppm Cu
Biogeochemistry has the potential to locate stratiform copper-silver mineralization that is concealed beneath glacial sediment cover
President and Chief Executive Officer, Dr. Sally Eyre, commented, "The 4,000 m of chargeable strike length successfully identified in 2012, in addition to the 6,000 m strike length of known copper-silver mineralization demonstrated by historical drilling, indicates the geological potential for a conceptual stratiform, sedimentary rock-hosted copper target that spans up to 10,000 m of strike length at Coates Lake. In addition to this, the deposit remains open to the north and at depth to the west and southwest."
Coates Lake deposit
The Coates Lake deposit is a stratiform, sedimentary rock-hosted, copper-silver deposit, that is located 116 kilometres north-east of the Cantung mine, Tungsten, Northwest Territories. At Coates Lake, mineralization comprises a high-grade, laterally continuous zone that has a demonstrated strike-length of over 6,000 m and extends down-dip for at least 2,400 m.
IP Surveys
21.3 line km of IP surveys were conducted at Coates Lake over two areas: a northern area and a southern area. Pole-dipole surveys were carried out at a spacing of 50 m or 100 m, observing 6 dipoles for a total of 12 lines. All IP data was modelled to produce 2D psuedosections and the southern area was modelled in 3D. Modelled chargeability anomalies from IP surveys were found to be coincident with known zones of stratiform, disseminated copper-silver mineralization. Chargeable anomalies present on four lines extend 3,000 m along strike from the northern limit of known stratiform copper-silver mineralization. A chargeable zone in the south of the property extends over 1,000 m strike length and is evident on 8 lines.
Drill-ready targets have been identified at Coates Lake (see accompanying Map) to further assess the potential for a large, copper-silver deposit; focussing on extending known high grade zones of stratiform copper-silver mineralization and exploring for thicker mineralized zones.
