The Ford Motor Co. of Detroit is not waiting for a seaway to be built to move iron ore through the St. Lawrence River to its plants at Detroit. By the end of the 1950 navigation season a total of 51 cargoes, totaling 102,428 gross tons of high grade Brazilian ore, will have been delivered at Detroit this year from Montreal, where it was transferred from large ocean ships. The ore, which is used in open hearth furnaces and averages 68% iron, is loaded into ocean ships in 10,000-ton lots at Victoria, Brazil. Ford first started using Brazilian ore in 1948, mixing it with lower grade domestic ore. Last year 50,000 tons were received. A new iron ore mine at Negaunee, Mich., work on which is to be started at once by the Jones & Laughlin Ore Co., is expected to produce more than a million tons a year at peak production, and to employ 650 men, the company announced yesterday. The shaft will be sunk to a depth of 1,600 feet and eventually to 2,500 feet, according to Harry S. Peterson, the company's general superintendent. The concern, which once was one of the major operators on the Marquette range, stopped activity in the area 31 years ago. Ten years ago it began diamond drill explorations at Negaunee on land purchased in 1921. The ore company is a subsidiary of the Jones & Laughlin Steel Corp. The new development, to be known as the Tracy Mine, will be within the Negaunee city limits.
