Quest is publicly listed on the TSX and NYSE MKT as “QRM” and is led by a highly-respected management and technical team with a proven mine-finding track record. Quest is currently advancing several high-potential projects in Canada’s premier exploration areas: the Strange Lake and the Misery Lake areas of northeastern Québec.

Quest continues to pursue high-value project opportunities throughout North America.
