Development Of Quebec-Labrador Iron Ore Deposits, Transportation Is Major Factor

DISCOVERY of large iron ore deposits in New Quebec and Labrador is, undoubtedly, one of the outstanding mining events of the twentieth century. To give an idea of size, the present concession is almost equivalent to a strip a mile wide around the earth at the equator. Importance of this iron ore area can best be appreciated by comparison to the famous Mesabi Range. On Mesabi, the area of favorable rock is 110 miles long and from 1 to 5 miles wide, with a, productive zone about 70 miles long. On the con- cessions the area of favorable rock in the Labrador Trough is 225 miles long and from 10 to 60 miles wide. In Quebec-Labrador, exploration already discloses that the productive zone is 90 miles long, with good chances of being extended at both ends. The Mesabi is covered generally by thick over- burden, and the iron ore deposits were found by T- test-pitting and systematic test-drilling. In Labrador and Quebec, most ore has been developed from a few surface deposits, and when it is considered that at least 95 pct of the area is covered by over- burden, and that there remains thousands of square miles of favorable territory still to be explored, it can be seen that the possibilities for developing additional ore are tremendous.
