142 MINERALS YEARBOOK

 The large low—grade porphyry copper deposit of the Chino Mines of
the Nevada Consolidated Copper Co. at Santa Rita was mined at the rate of
6,474 tons daily for 180 days in 1932 compared with 7,178 tons in 1931 (actually
8,852 tons for 296 days). The deposit is mined by open-pit methods, using
steam and electric shovels, and the ore is concentrated at the company flotation
mill at Hurley, which has a daily capacity of 15,000 tons in all seven units.:
The Lordsburg district, the second largest gold and copper producer in the
State in 1931, in 1932 shipped 16,608 tons of siliceous copper-gold-silver~ores,
containing 1,404 ounces of gold, 37,561 ounces of silver, 936,100 pounds
of copper, and 59,284 pounds of lead, compared with 96,032 tons in. 1931,
which contained 11,287 ounces of gold, 137,73.1 ounces of silver, 4,725,223
pounds of copper, and 186,196 pounds of lead. As usual, the ore was shipped
to Douglas, Ariz., and El Paso, Tex. The largest producing mine in this district,
the Eighty-Five, was closed soon after January 1, 1932. The only other producer
in 1932 was the Bonney mine.
 The Pecos mine of the American Metal Co. on Wifiow Creek, San Miguel County,
in its sixth year of production, continued to produce at the rate of 538
tons a day. The ore minerals in this comple~ç sulphide ore body are
sphalerite, galena, chalcopyrite, and pyrite, and the gangue is a sheared
micaceous diorite. The ore bodies are mined both by the cut-and-fill system
and by square-set stopes. The mine and mill are connected by a 12-mile aerial
tramway. The capacity of the mill, a selective flotation plant, is 600 tons
a day. In 1932 the mifi produced 44,681 tons of zinc concentrates and 17,665
tons of lead-copper concentrates compared with 44,780 tons and 18,911 tons,
respectively, in 1931. The actual heads of ore into the tnill in 1932 averaged
0.112 ounce of gold, 4.24 ounces of silver, 0.89 percent copper (wet assay),
4.89 percent lead (wet assay), and 15~50 percent zinc. This mine is the largest
single producer of gold, silver, lead, and zinc in New Mexico. Other producers
of zinc concentrates were the Black Hawk (or Combination) selective flotation
mill at Hanover, which was operated continuously, and the Peru selective
flotation mill at Wemple, near Deming, which was operated the last 3 months
only. Zinc concentrates produced in New Mexico in 1932 amounted to 55,870
tons containing 61,576,492 pounds of zinc and averaging 55 percent zinc.
 Several cars of silver-gold ore were shipped to the El Paso smelter from
the Cochiti or Bland district, Sandoval County; several, shipments of gold-silver
concentrate were made from* the Mogollon district, Catron County; and several
small shipments of gold-silver ore were made from Tres Piedras and from Red
River, Taos County. Small lots of placer gold bullion were shipped from the
Mt. Baldy district, Colfax County; the Pinos Altos district, Grant County;
the Jicarilla district, Lincoln County; the Hifisboro district, Sierra County;
the Orogrande district, Otero County; and the Golden district, Santa Fe County.
TEXAS

 Although no output of gold, silver, copper, or lead was recorded for Texas
in 1931 a small output of each of these metals was reported in 1932. As shown
in the accompanying table $180 in gold, 1,421 ounces of silver, 7,000 pounds
of copper, and 34,000 pounds of lead were recovered, with a combined gross
value of $2,042.
