The DTR results from 26 mineralized bedrock samples taken at Mich show excellent recovery of nickel, iron and chromium, with trace amounts of sulphur. The DTR nickel values average 21% higher than the comparable partial extraction nickel-in-alloy sample results. This increase is likely due to the coarse-grained nature of the nickel alloy mineralization at Mich and is considered a very positive indicator of magnetic recoverability.
The results of a ground-based magnetic geophysical survey conducted in 2012 show a continuous high magnetic response extending southeast of the key target area for another 3 kilometres along strike under the overburden.
Work on the Mich property in 2013 will include detailed geological mapping and sampling in the target area, including channel sampling to better define potential drill hole locations. The ground-based magnetic survey will also be extended to the southeast to further define and test covered areas.
The Orca and Wale properties are located 45 kilometres east of Dease Lake (situated on BC Highway 37 between Stewart and Cassiar) and together cover an area of 157 square kilometres in the Stikine Ranges of northern B.C. These neighbouring properties encompass a 30-kilometre-long belt of ultramafic rocks of the Cache Creek Terrane. Access to the properties is by helicopter, directly from Dease Lake, and by a rough mining road and trails using all-wheel drive, heavy duty utility vehicles, which service the nearby jade and placer gold mining operations active in the area.
A large northwest-southeast trending zone of awaruite mineralization was first discovered at Wale in 2011 during a regional exploration program, and mapped in greater detail early in the 2012 field season. The adjoining Orca property was staked in November 2011 based on anomalous sample results generated from regional exploration work. Three main targets have since been identified - Orca, Eagle and Garth's Knob, the latter two occurring on the Wale property. The target areas have been defined based on visual grain size estimations, partial extraction analysis for nickel-in-alloy and preliminary Davis Tube magnetic recovery analysis. The Orca-Eagle-Garth's Knob mineralized trend measures a total of 14.5 kilometres in length.
The Orca property adjoins Wale to the northwest. It was staked in November 2011 based on anomalous sample results generated from regional exploration work. Detailed mapping and sampling in 2012 delineated a target measuring 1,400 by 750 metres as defined by awaruite grain size and 118 surface rock samples averaging 0.113% nickel-in-alloy, 5.4% iron, occurring primarily as magnetite, and 0.2% chromium. The surface samples range in value from 0.06% to 0.211% nickel-in-alloy and contain common-to-abundant, fine-to-coarse grains of disseminated nickel-iron alloy spanning from less than 50 to more than 300 microns (0.05 to 0.3 mm) in size.
The mineralized zone is exposed along the top and northeast flank of a northwest-southeast trending ridge. The mineralization begins on the flank at an elevation of 1,300 metres and extends more than 700 metres vertically to the summit, which reaches 2,020 metres in elevation.
Davis Tube magnetic separation analysis was conducted on 62 of the Orca rock samples, with results suggesting portions of the target area are amenable to magnetic recovery, including an irregular-shaped, coarser-grained area measuring 1,300 metres long and 150 to 700 metres wide. Thirty-four of the samples reported grades better than 0.08% DTR nickel, with an 80% recovery of the nickel alloy relative to the partial extraction analysis. The difference between DTR and partial extraction nickel analysis values may be caused by the presence of very fine-grained awaruite, which may not be recoverable using Davis Tube magnetic separation methods.
