CHIi SECOND BIG MINE OFTHE IAICRLD Recent Additions to Tonnage Bring Reserves to Very High Point. According - to usually well Informed eastern circles, the Chlno mine of New Mexico deserves to be known now as the second greatest porphyry mine, from a tonnage standpoint, In tho world, crowding tho Ray Consolidated property from this point of prosllge. and bringing the Chlno second only to the great Utah Copper proposition of Bingham. Another distinction recently added to the Chlno laurels Is that or being tho lowest cost copper producer In' tho world, basing the production cost entirely upon the production pro-duction of copper without the assistance of nny auxiliary means of making proilts. During tho past few months there have been some very significant developments at tho Chlno, and the oro reserves have been Increased materially. At the time of the Inst report regarding tonnage, tho Chlno ores measured the high point of 55.000,000 tons, thn copper average of which was 2.2i per cent. Much of thl3 ore was capable of being mined by means of tho .steam shovel systom, and enough Is available Tor thirty years' supply for the mill sfM It Is constituted at present. It is now stated that the company could revise Its cellmate and by shaving approximately 0.3 per cent from the average av-erage of tho tonnage given, and by taking tak-ing into consideration the newly opened tonnage. lay claim to approximately 00,000,000 tons of 1.0 per cent copper ore. It is taken for granted that the Chlno eventually will be forced by ilr. Increasing Increas-ing tonnages to add more sections to its concentrating plant, bringing It to the second high point In tonnago handjed and copper produced.
