Tunerq (Nickel)

While prospecting for diamonds a high-grade nickel prospect now known as Tunerq, was discovered on the Amaruk property in Nunavut. Grab samples from the highly oxidized outcrop yielded nickel values ranging from 1.71% to 0.51%, with significant copper and cobalt credits. The initial drill program conducted on the prospect was designed to gain geological information such as depth extent of sulphide mineralization below the outcrop exposure, to obtain fresh unaltered samples for analysis and to develop a better understanding of the orientation and extent of the mafic -- ultramafic body that hosts the sulphide minerals. Mafic -- ultramafic rocks and more felsic components of the intrusion appear to be undeformed and are interpreted to be much younger than the surrounding granodiorite country rock.

The extent of the host rock appears open; recent surface mapping has revealed that it extends at least 400 to 500 metres from the discovery outcrop. The nickel sulphide zones have been tested over about 70 metres in a north-south direction and 75 metres in an east-west direction. The mineralization is open along strike and down dip. In hole 08TUR002, samples over 1.52 metres exceed 2% Ni and are as high as 3.95%. Sulphides range from disseminated to net-textured and semi-massive. True thickness of nickel sulphide mineralized zones is not known.


  • Hole 1 intersected 1.20% Ni, 0.26% Cu and 0.03% Co over 12.2 metres within a 22.9 metre zone containing 0.83% Ni and 0.19% Cu.
  • Hole 2 intersected 2.49% Ni, 0.56 % Cu and 0.05% Co over 9.1 metres within a 34.8 metre zone containing 1.05% Ni and 0.26% Cu.
  • Hole 4 intersected 1.86% Ni, 0.36 % Cu and 0.04% Co over 5.8 metres within a 7.3 metre zone containing 1.50% Ni and 0.29% Cu.
  • Preliminary mapping extends the gabbro -- ultramafic complex over 400 to 500 metres.

Work to date has identified significant mineralization at Tunerq. Numerous other mafic and ultramafic occurrences on Amaruk suggest that Tunerq could be part of a larger nickel district.
