Jan 25, 2016 (A Wilson) - The Tandem-1 kimberlites is unusually fresh and unaltered in contrast with nearby kimberilsits. Its well-preserved mineralogy is comparable with mineralogy of the Guigues, NDN No.1 and NDN No.2 pipes in the New Liskeard area, but is not typical of the kimberlite occurrences near Kirkland Lake. The kimberlite contains numerous mantle xenoliths that are also relatively unaltered. The fres, well-preserved mineralogy suggests tht this intrusion represents a much younger intrusion than those previously found in the region.
