The inner and upper margin is very indefinite, being fixed in mining simply by commercial considerations. The thickness of workable ore may vary from a few feet to 100 feet, or more; the length is equally variable, ranging from 100 feet or 200 feet to 700 feet. The depth to which marginal deposits go is unknown.
