Summary(Plain Language Summary, not published)
A mineral occurrence database for mineral showings and deposits in the Great Bear magmatic zone, Wopmay Orogen, was created for use as a layer for mineral prospectivity modelling and remote predictive mapping for the Great Bear - Multiple Metals Project, Geo-mapping for Energy and Minerals program. The majority of the data points were originally extracted from NORMIN, the mineral showings database of the Northwest Territories Geological Survey in 2010. Other initial data came from the World Minerals Geoscience Database Project. Then both old and new data sources such as maps and diagrams from assessment reports and technical reports filed on SEDAR were georeferenced, and sites of mineralization were extracted as accurately as possible using GIS techniques. Many of the original NORMIN and WMGDP showings were thus relocated so that they could be used as a verification layer to test the modelling results. New showings were added from new literature and technical reports.
