A /Vlethod of Mining Low Grade Ores in theBoundary Creek District. By Frederic Keffer, , Anaconda, It is usually the case in new districts presenting a variety of newconditions, that a good deal of preliminary work must be done todetermine the best methods of mining and treating ores. This hasbeen true in the Boundary District, the ores of which, as a rule, are ofvery low grade, occurring in deposits of great extent without welldefined walls. It is the purpose of this paper to describe the methods of miningat the Mother Lode mine in Deadwood Camp, near Greenwood, andthe reasons which have led up to their adoption. The ore deposit here outcrops at intervals for a distance of about2,000 feet, the width in explored portion averaging perhaps 140 feet,although the absence of any defined walls prevents exact measuresbeing given. The dip is about 70 degrees easterly, and pitch towardthe south at an angle yet undetermined. Only the ground to the northof the shaft, which is located ce
