North American Nickel Inc. (TSXV:NAN,OTCBB:WSCRF) announced the Geological Survey of Denmark and Greenland says the Maniitsoq Structure is the site of a three billion year old meteorite impact.
As quoted in the press release:
In the paper, the authors postulate that crustally contaminated intrusions of the Greenland Norite Belt (GNB) are products of the impact. The GNB has been the focus of the NAN’s work at Maniitsoq since it initiated the project last year. NAN is interested in the GNB because it is aerially extensive (the main belt is over 70 km long and up to 15 km wide), is comprised of noritic intrusions that show evidence of crustal contamination (believed to be important in the formation of nickel-copper sulphide ores), hosts numerous historical high-grade nickel occurrences (e.g. 9.85 m averaging 2.67% Ni and 0.60% Cu at the Imiak Hill showing) and is remarkably under-explored.
