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. The purpose of this contribution is to present the preliminary results on several ultramafic intrusions discovered in 2013 during regional bedrock mapping project conducted by the Ministère des ressources naturelles du Québec within the La Grande and Opinaca sub-provinces in the Richardie lake area located south of the La Grande 4 reservoir in the James Bay area. This project is part of a collaborative effort under the TGI-4 program between the Geological Survey of Canada and the Ministère des ressources naturelles du Québec to better characterize and understand the mineral potential of these intrusions in the James Bay area.
