1 duced 32,952,133 pounds, or 97 per cent
 of the total yield.
 | The increase in the copper output 1 came chiefly from the operations of the l Chino Copper company, which is min- 1 ing a great lOWgrade copper deposit at ! Santa Rita by steam shOVels. This ore 1 is concentrated at Hurley, where a 5,O00-t ton plant has been erected in five i sections, two sections being in opera
 tion at the beginning of the year 1912 and the other three being successively 1 placed in operation during the year, | the last being completed in December l The annual report of this company | shows that no more than four sections 1 of the plant were operated continu- | ously for any part of the year 1912, but l it is planned to operate all five sec | tions. The total gross production by 1 this company was 29,237, ,966 pounds of | copper. The average copper content of l the ore treated was 2.077 per cent, and l the average recovery of copper con
 tained in concentrates was 61.63 per
 cent equivalent to 25.6 pounds of cop 1 per per ton of ore treated.
 The LOrdsburg copper district was l second in importance, with an output 1 of 3,155.5 1885 pounds, an increase of 7OO,- = 1 output from Hanover and Pinos Altos. 1 The Burro Mountain district, where
 much development work has been done in the last six years. made a small out put. The copper mines and smelter at San Pedro. Santa Fe county, were re- opened in August and operated throughout the rest of the year.
 Of the lead output Grant county
 produced 2,3O9,732 pounds chiefly from the Central district; the Magdalena dis district. SOcorro county, yielded 2,192.- i 792 pounds; Luna county yielded S27,- 556 pounds, chiefly from the Victoria district; and the Gallinas district, Lin coin county, yielded 103,911 pounds. The increase for the state for 1912 was 2,527, ,796 pounds. Concentrates con-
 tained L9S4,435 pounds of lead. and crude ore sent to smelters 3,509,5S3
 pounds
 The tonnage of zinc sulphide con-
 centrates from Kelly, Socorro county,
 decreased somewhat, but the tonnage
 of zinc carbonate ore increased, with
 a resultant small increase in zine yield
 for this county, from which comes the
 greater part of the zinc output of New
 Mexico. In addition to the magnetic
 separation and wet-concentration min
 of the Fri ri-BulliOn company the new
 concentration mill of the Ozark com
 pany, (With Notation equipment also).
 was placed in operation in 1913, and
 the output for 1913 may show a con
 siderable increase. In January, 1912,
 the zine deposits at Hanover, Grant
 county, were reopened after being idle
 a year, and a large tonnage of zinc concentrates was shipped from Pinos Altos. In Luna county a considerable
 tonnage of zinc carbonate was shipped from the Cooks district. and several shipments of zinc carbonate were made from the Tres Hermanas and Victoria districts.
 The number of productive mines in New Mexico in 1912 was 145. of which 26 were placers, against 1O5 in 1911, of which 20 were placers. The average total recoverable value per ton of ore produced decrease from SHEA in 1911 to $6.29 in 1912, owing to the large ton mage of low-grade copper ore handled by the Chino Copper company A totaf of 1852, ,2S6 short tons of ore from New Mexico was sold or treated in 1912, an increase over 1911 of 1,119,5S7 tons. Of l this total 106,19S tons went to anal gamating and cyaniding mills. 1,142, ,O02 1 tons went to mills for concentrating | only and 104,0S6 tons went crude to | sme1ters
 Of the $420,447 in gold and S42,01S l ounces of silver in bullion produced in | New Mexico in 1912, the cyanide pro- | cess yielded s3S3,69S in gold and SAL 575 ounces of silver, the remainder be- 1 ing recovered by amalgamation.
