Copper North Mining Corp. announces that it has commenced exploration of its Thor property in north west British Columbia. Initial exploration will focus on evaluation of targets in the Thor East area followed by drilling in both the Thor West and Thor East areas. Diamond drilling of these targets is scheduled for late August.
The Thor project provides Copper North an opportunity to explore for porphyry copper-gold type mineralization in the slopes and valleys adjacent to the shutdown Kemess South mine and mill complex in North Central BC.
The favourable geology covers approximately 16,000 hectares covering the historic Thor and Marmot properties. Initial exploration in the 1960's to 1990's defined porphyry copper-gold type mineralization on Thor.
Thor West
Copper North completed additional geophysical surveying in the fall of 2014, covering much of the claims area in Thor West, and further defined targets for reconnaissance drilling in the Moose Valley portion of the property. The geophysical surveying defined a large induced polarization target in Moose Valley initially identified as Area 1 (see map Appendix A) and now referred to as the Thor West target. The Thor West area is hidden by overburden on lower slopes in the valley bottom. Magnetic data indicate a large anomaly of elevated magnetic susceptibility that hosts a smaller area of reduced magnetics and modest increase in chargeability from the induced polarization (IP) survey data. The Thor West IP target covers an area approximately 4 kilometres long by 2 kilometres in width.
Thor East
The Thor East target is located in the more mountainous area forming the eastern portion of the property. Historical exploration work in the 1980's identified anomalous copper and gold in soil and rock geochemical samples in the steeper terrane that flanks Moose Valley (areas 2, 3, and 4 on the target map). Six shallow drill holes totalling 692 metres were completed in area 3 in 1997. Four holes tested shear zones in the Takla volcanic rocks. One drill hole tested the contact between granodiorite and volcanic rocks and intersected 60 metres grading 0.12% copper and 0.04 g/t gold (see map Appendix A). The potential quantity and grade is conceptual in nature, there has been insufficient exploration to define a mineral resource and it is uncertain if further exploration will result in the target being delineated as a mineral resource.
The anomalies for drilling flank the small granodiorite intrusions in contact with the Takla volcanic rocks. Widespread gossan zones are related to the oxidation of sulphide mineralization. The area is structurally complex, suggesting two intrusions, or perhaps a single intrusion that has been juxtaposed on faults, covering an area 6 kilometres long by 2 kilometres wide.
