A Zn-Pb-Cu-Ag-Au-onyx-calcite-spurrite-dumortierite occurrence/mining area located in the Tres Hermanas Mountains, in the far southeastern corner of New Mexico in Luna County.
General & History: The Tres Hermanas district is located in a small group of mountains of the same name a few miles northwest of Columbus. The exact value of the minerals produced from this district is not known. A reasonable estimate is $500,000 (period values), and the area is believed to be the third-ranking metal-producing district of the county, excluding manganese. Ranked in accordance with past production, zinc and lead were the most important metals produced, but significant amounts of silver, gold, and copper also have been mined. Deposits of Mexican onyx, fluorescent calcite, spurrite, and dumortierite have been exploited for mineralogic specimens and semiprecious gem stones, but descriptions of these deposits are contained in a later section.
The early history of the Tres Hermanas district is vague. The deposits were thought to have been discovered around 1885. According to Lindgren (1909), several mines were operating in the area in 1905, the Cincinnati, Hancock, and Mahoney (Thurman & Lindauer) mines being the most active. The Mahoney mine (actually a group of several mines) operated fairly continuously until 1920. Only sporadic production has been effected since that time. During the fall of 1959, a copper prospect was being investigated in the southern part of the district; this constituted the only mining activity in the district at that time.
The Tres Hermanas Mountains are virtually covered with small prospect pits, but the principal producing mines of the past are located in the northwestern part of the range. Lead-zinc limestone replacement deposits occur at the Mahoney and Lindy Ann mines, and vein deposits occur along the Marie—Cincinnati—Hancock—Black Hawk vein system.
In the southeastern part of the district, near South Peak, several small zinc deposits occur in some of the limestone outcrops adjacent to the quartz monzonite stock. A few copper prospects are located in the andesite breccia belt that surrounds the southern end of the mountain group. Minor lead-zinc-copper deposits also have been prospected east of North Peak and in the Lower Cretaceous sediments west of the Black Hawk mine.

The Tres Hermanas district is located near Columbus in southern Luna County and was discovered in 1881. Total production from the Laramide skarn and Laramide vein deposits in the district is unknown, but is estimated from 1885-1957 as $600,000 worth of copper, gold, silver, lead and zinc, including 200,000 lbs Pb and 1 million lbs Zn (Table 42). The Cincinnati, Hancock and Mahoney mines were active in 1905 (Lindgren et al., 1910) and the Mahoney mine remained in production until 1920 (Griswold, 1961). In 1906-1907, ore was shipped to the Mississippi Valley area for smelting (Lindgren, 1909). The results of drilling in the Tres Hermanas Mountains in the early 1980s are unknown.
Three types of deposits occur in the Tres Hermanas district (Table 43, Fig. 22): Laramide veins and Laramide skarn. The age of the mineral deposits is Tertiary; they most likely formed after intrusion of the quartz monzonite but prior to intrusion of the basaltic dikes (Griswold, 1961; Doraibabu and Proctor, 1973). Geochemical data are consistent with a source of mineralization from the quartz monzonite, although locally the older bedrock may have contributed metals (Doraibabu and Proctor, 1973). Multiple periods of mineralization are likely, because of the variations in mineralization styles and alteration.
The most productive deposits are the Laramide skarns which occur in the Escabosa Limestone (Mississippian) and overlying Pennsylvanian sedimentary rocks (Table 43). The replacement deposits are tabular to pod-shaped and are controlled by fractures and faults which trend east-west and north-south. Silicification is common near these deposits (Griswold, 1961). Ore minerals consist predominantly of sphalerite, galena, chalcopyrite, willemite, smithsonite and other oxidized lead-zinc minerals in a gangue of calcite, quartz, pyrite, and calc-silicate minerals (Wade, 1913; Homme and Rosenwieg, 1970). Ore at the Mahoney mine averaged 26.7% Pb, 34.5% Zn, and 5.9 oz/short ton Ag. Gold assays range as high as 1,500 ppb Au (Griswold et al., 1989). The Mahoney and Lindy Ann mines are the largest producers (Table 43). Skarns are locally common in the limestone xenoliths and limestones adjacent to the stock (Table 43). Scheelite is reported in a tactite near South Peak (Griswold, 1961).
Fissure veins in quartz monzonite contain galena, willemite, smithsonite, and hydrozincite and, samples assayed 29-37% Zn, 11-40% Pb, and 2 oz/short ton Ag (Lindgren, 1909). Veins also occuarl ong faults and fractures in Paleozoic sedimentary clastic rocks, quartz monzonite, and Tertiary volcanic rocks. The most productive veins, such as the Cincinnati, trend east-west; the north-trending veins have been less productive (Table 43; Doraibabu and Proctor, 1973). The Cincinnati vein strikes N75E, dips 75-80S, and is 10,000 feet long. Most veins are less than 4 ft wide. Disseminated pyrite, chalcopyrite, sphalerite and galena occur sporadically throughout the quartz monzonite stock (Table 43), suggesting the potential for a porphyry copper and/or copper-molybdenum deposit; although the stock is not extensively altered as typical porphyry copper deposits. However, drilling in the stock has failed to reveal any economic concentrations (Griswold, 19N61M; BMMR file data).
Most of the mines in the Tres Hermanas district are shallow; only a few reach depths of 300-500 ft. None of the deposits have been explored at greater depths, especially in the Mahoney and Cincinnati mines (Griswold, 1961). Areas of pyrite disseminations need examination for example secs. 26, 27, T27S, R9W. Where alluvium covers the extensions of these deposits is also favorable, but requires drilling. Anomalous concentrations of As, Ba, Be, Co, Cd, La, Mn, Mo, Pb, Sb, Th, Ti, Y, and Zn are found in stream-sediment samples from the area.
Marble occurs adjacent to the quartz monzonite surrounding the Tres Hermanas Mountains (Griswold, 1961; Leornard, 1982). The marble was originally Paleozioc, is medium- to coarse-grained, and contains local intercalculated bands of garnet. The quantity of resources of marble for dimension stone is unknown. Yellow and white travertine (Mexican onyx) occurs in bands as much as 5 ft thick in latite on the southern slopes of the Tres Hermanas Mountains (sec. 24, T28S, R9W) and could be mined for local use. Spurrite, a rare pale-gray to purple mineral, is valued by collectors and used as an ornamental stone, and occurs in a limestone xenolith in quartz monzonite on the east slope of South Sister Peak (Griswold, 1961).
