In a newly conceived mining enterprise serious operating problems may remain concealed until encountered in the actual early operating period of the property. The major problems of the Silver Dyke Mine were of this nature. This mine is the property of the Silver Dyke Mining company, a subsidiary of the American Zinc, Lead and Smelting Company. It is situated about five miles from Neihart, Montana. A three-and-one-half-mile trucking road connects the mine with a railway siding. The property is in the Little Belt Mountains, at an elevation of about seven thousand feet. The climate is severe, the winters long, and the snow fall heavy in the spring --page 1
