| Summary | (Plain Language Summary, not published)
The Targeted Geoscience Initiative (TGI-4) is a collaborative federal geoscience program that provides industry with the next generation of geoscience
knowledge and innovative techniques to better detect buried mineral deposits, thereby reducing some of the risks of exploration. This poster was presented at the Manitoba Mining and Minerals Convention in Winnipeg in November 2014. The Mayville
intrusion is the largest mafic-ultramafic intrusion located in the northern arm of the Bird River greenstone belt (BRGB) in southeastern Manitoba. This intrusion host the M2 magmatic Cu-Ni-PGE deposit (31.8Mt at 0.45%Cu, 0.18%Ni, 0.19ppm PGE) as well
as some PGE and chromite occurrences. The E-Ext stripped outcrop is located near the base of the intrusion. Field obervations on this outcrop permitted to discriminate between at least four different types of chromite hosted by pyroxenite. |
