Faribault and Fletcher published 70 map sheets with a scale of 1 inch = 1 mile (1 : 63,360), as well as many cross sections and detailed plans on scales as large as 1 inch = 500 ft (1 : 6000). These geological maps represent, in most cases, the first accurate delineation of many of the province's coalfields and continue to stand today as examles of excellence in field geology.

In 1885, Faribault (who had been working under the direction of Fletcher) took on the task of mapping Nova Scotia's gold fields. He concentrated mostly on the intricate folds in the gold-bearing series of rocks along the southeast coast of Nova Scotia known as the Meguma Group. Realising that the gold occurred like saddles along the crests of small anticlines, he discovered many orebodies, most of which were small. These discoveries were fundamental to our present understanding of the location of gold in Nova Scotia.
