The Exploration of a Sulphide-Bearing Belt, Labrador and New Quebec

The eastern portion of the Late Precambrian geosynclinal structure known as the Labrador Trough comprises a 16,000-square-mile sulphidebearing belt of good potential as a base metal exploration area. Hollinger and Hanna mining interests have carried on exploration in the region ince 1953, with encouraging results. This program has been considerable in terms of both effort and expenditure, and has resulted in an apparently successful primary evaluation of the entire belt. Much detailed work remains to be done in the area. Exploration to date has been largely of a reconnaissance nature, employing various methods in common use in Canada today. In the course of this work, several deposits of promise, containing near-economic quantities of copper, zinc, nickel and other metals, have been located. A broad classification of these deposits is proposed. Exploration in the sulphide belt was started on the basis of partial control of the area under mineral exploration concessions. This was necessary to justify operations in an area of difficult access and high operating costs. The results of this now-terminated arrangement are regarded as being of benefit to those directly concerned as well as to the mineral industry in general.
