Metal Mining Sees Transition to:

Low metal prices prevailing at the beginning of 1950 stimulated the search for improved mining methods. More experience was gained during the year with such new developments as the jackleg drill, millisecond delays as applied underground, trackless mining, and Diesel powered equipment. One of the outstanding innovations in mining practice was the starting of the Round Mountain "dry land gold dredging operation." The Government is now inviting the mining industry to open up every available source of new metal supply and this circumstance will undoubtedly speed the development of new machines. New methods will also result but it is doubtful if economic efficiency will be at its peak.
