“…In addition, Late Cretaceous Virden Formation crops out south of the district west of Steeple Rock, and a Tertiary or Cretaceous rhyolite dike or plug constitutes Twin Peaks in the northern part of the district. Griggs and Wagner (1943) distinguish other rhyolite intrusive masses in the vicinity of the Carlisle mine.…”

Grant County has produced more than a billion dollars worth of metals and minerals since 1880. Most of this has come from the eastern part of the county, but important amounts of copper, gold, silver, fluorspar, and turquoise were mined from the western half. Lesser amounts of zinc, lead, and manganese and small amounts of tungsten, uranium, perlite, and ricolite have also been produced. Concentrations of other commodities present include nickel, cobalt, bismuth, molybdenum, and rare earths.Mineral deposits occur in the Precambrian igneous and metamorphic rocks and in the Tertiary volcanic rocks that occupy most of the western part of the county. They are associated with northwest and northeast-to-east fractures and with intruded stocks and plugs. Major districts are at the intersection of the structural trends.The largest and most productive mineral deposits are in the Big Burro Mountains. The supergene-enriched copper deposits at Tyrone have accounted for most of the copper produced, and the outlook for future production is excellent. Copper also occurs elsewhere in the mountains, and numerous deposits have been exploited. Fluorspar and turquoise have been mined, and large amounts of fluorspar still remain. In the White Signal subdistrict, gold, copper, and uranium deposits are numerous. Mining here essentially has been confined to the oxidized zone, and only small amounts of gold, radium, and uranium have been produced.In the Steeple rock district, gold and silver were the major commodities produced in the early days of mining, but in recent years lead, zinc, and copper have been extracted in significant amounts. In the Bullard Peak district, silver was produced from veins that contain native silver, nickel, cobalt, and uranium.Other major districts include Gold Hill, Gila, Redrock, Malone, Little Burro Mountains, and Soldier's Farewell. Excluding perlite, diatomite, clay, and dimension stone, most of the mineral deposits are hydrothermal in origin, but oxidation and supergene enrichment have been important in concentrating the low-grade ores into deposits of economic worth. A few small deposits in the Redrock area were formed by metamorphic processes. Rare-earth-bearing pegmatites are in the Big Burro Mountains and Gold Hill.

“…At the Carlisle, and apparently at East Camp, ore shoots are localized by changes in strike and dip of veins, and possibly by changes in wall rock. Two or three stages of mineralization have been identified (Griggs and Wagner;C. W. Botsford, written communication, 1918;J.E.…”

“…The earliest published report is a brief description of the district by Graton (19lO). In 1943, Griggs and Wagner (1943) mapped and described the Carlisle mine area; and, in that same year, Johnson (1943) published a brief description of the Steeple Rock district, in particular of the Carlisle mine, and recommended an exploration pro: gram in the Carlisle area. The latest published article is by Russell (1947), who described the exploration done in the Carlisle mine area by the U.S. Bureau of Mines during 1944.…”

The Steeple Rock mining district of western Grant County, N. Mex., is in an area of block-faulted Tertiary lavas that have been intruded by rhyolite dikes and plugs. About $7 million in metals, mainly gold and silver, has been produced from mines in this district since 1882. A body of base-metal sulflde ore, uncommon in the Steeple Rock district, was exploited at the Carlisle mine from 1943 to 1946.The ore occurs in veins that occupy premineralization faults which cut the volcanic sequence. The faults belong to three groups, but nearly all the known ore is closely related to the northwest-trending group or to fault intersections.The sulfide ore occurs in a breccia zone at the intersection of the east-trending Carlisle fault and the northwest-trending Apache fault. The sulfide ore minerals are sphalerite, galena, and chalcopyrite in a gangue of quartz and altered breccia. The precious-metal ores of the district, which are associated with quartz in fault breccia, were not being mined at the time of the investigation and could not be studied in detail. In one rich specimen the silver-bearing mineral is argentite; gold probably occurs as the native metal. Additional bodies of goldsilver ore probably will be discovered.
