Perhaps Dunn's most significant legacy was the discovery of a productive ore near Bathurst, which was exploited by as many as 700 men for half a century from 1953: One of the annual scholarships, that were provided by Dunn in 1947 to the University of New Brunswick, was awarded to a Master's student by the name of A.B. Baldwin, who discovered the ore as his thesis work and thus "greatly enlarged the bounds of provincial prosperity". In fact, Dunn had specified in the deed that the scholarship was to be awarded for only New Brunswick geological work; Baldwin, who was originally interested in samples from Quebec's North Shore, was led by the Dunn gift to examine ore from New Brunswick.
