Announcement

2017 Ontario Prospectors Exploration Showcase

April 4—6
Prospecting: Where it all Begins
Valhalla Inn, Thunder Bay

Staff of the Mines and Minerals Division, Ministry of Northern Development and Mines, will be participating in the 2017 Ontario Prospectors Exploration Showcase in Thunder Bay. This year’s theme, Prospecting: Where it all Begins, is about the exciting discoveries that continue to make Ontario one of the most attractive places in the world to explore. Ministry staff will be presenting posters and talks on recent field work, geoscience projects and initiatives, and summaries of current exploration activities in Ontario. The showcase provides an excellent forum for members of Ontario’s prospector, mining and exploration community to gather for the exchange of geoscience and exploration information. For registration and other information about the showcase, please visit the Ontario Prospectors Association Web site.
