North American Nickel Inc. provides details comparing the electromagnetic (EM) results from its recently completed SkyTEM helicopter-borne survey and those from a 1995 vintage GeoTEM fixed-wing survey.
SkyTEM geophysical system is detecting conductors not seen before and is also resolving previously known EM anomalies in much greater detail. These results have met or exceeded NAN’s expectations and firmly establish that the new exploration technology available today is able to identify new, previously unrecognized targets.
The area surveyed in 2011 comprises only 8% of the total Maniitsoq project. Based on the success of this program, additional areas are now being evaluated for helicopter-borne surveying in 2012.
NAN Chief Geologist John Pattison states: “The 1995 GeoTEM fixed-wing survey was the only large scale, airborne Time Domain EM survey ever performed in the Maniitsoq nickel belt prior to our SkyTEM survey. The SkyTEM system has identified new EM targets. It is clear to us that we now have a powerful exploration tool that provides us new opportunities for the discovery of nickel-copper PGM deposits in an underexplored area of the world, adjacent to year round, ice free tide water.”
As reported in the December 6th 2011 news release, NAN completed 2,217 line-kilometers of SkyTEM helicopter time domain EM (TEM) surveying this past summer covering two blocks of ground totalling 373 km2 within its 4,841 km2, 100% controlled, mineral exploration licence.
Block 1 is situated at the northern end of the 80 plus kilometre long norite belt and hosts the largest of the known nickel bearing norite bodies and strongest nickel occurrences discovered to date in the belt. Block 2 covers a four kilometre long rusty norite body northwest of the main norite belt trend.
In 1995, there were only three significant (>2 channel) responses and they were all single line anomalies associated with exposed mineralization at the Imiak Hill, Fossilik II and Spotty Hill showings. The cluster of 1 and 2 1995 channel anomalies on the west side of the block corresponds with a lake and is probably caused by conductive sediments.
In Block 2, the 1995 GeoTEM system only detected one weak (2 channel) anomaly near the northern boundary of the block, while the 2011 SkyTEM survey outlined 8 target zones one of which (B2-B) corresponded to the lone GeoTEM anomaly.
