Location and access: A lead-zinc deposit in Paleozoic sediments is known in the E1/2 sec. 26, T. 27 S., R. 9 W., approximately 2 miles east of the Mahoney mining area (pl. 1). Access to the deposit is from the same road that leads to the Mahoney mining area; a truck trail turns off toward the southeast about 1 mile north of that area and leads to the prospect, which is about 2 miles from the turnoff.

History: Little is known of the history of the development of the deposit. The topographic map of Columbus quadrangle, surveyed by the U. S. Geological Survey in 1917, shows a road leading to the deposit and several buildings in the immediate vicinity. This indicates that the deposit was discovered previous to 1917, but more definite information is not known. The most recent work on the property, other than assessment, is believed to have been done by John M. Crump, who worked the deposit during the 1930's. The amount of ore shipped from these claims is believed to have been small.

Geology of the deposit: The claims are located on the west slope of a north-trending ridge of Paleozoic sediments extending outward from the quartz monzonite stock (pl. 1). The lower part of the ridge is gray, massive to thick-bedded Fusselman dolomite. The formation strikes almost due north with steep to moderate east dips. On the northwestern part of the ridge a thrust fault has displaced the Permian Hueco formation, so that it rests directly on the Fusselman dolomite of Silurian age, the Devonian rocks having been removed by the fault. The approximate strike of this thrust fault is north-northwest, with a moderate dip to the east. If the fault is interpreted correctly, the overthrust was to the west-southwest.

The southern edge of the ridge terminates against the Tres Hermanas quartz monzonite stock. The contact is very irregular, but the general trend is southeast. Several east-striking monzonite dikes cut the sediments, north of the main contact. One of these dikes appears to have been a controlling factor in the deposition of ore at the Lindy Ann. The deposit consists of galena, sphalerite, pyrite, and possibly other sulfides occurring in irregular, small replacement bodies. Most of the mine workings, consisting of a shallow shaft and several short adits, are confined to the contacts of a 10- to 20-foot-thick east-striking monzonite dike located a few hundred feet north of the main sediment-quartz monzonite contact. The ore appears to have been controlled by postdike fractures and (or) minor faulting along the dike contacts. About 500 feet northwest of the above mine workings, another shallow shaft was sunk, and some stoping was done on a vein structure striking N. 45° E. with a nearly vertical dip. The east wall of the vein is strongly recrystallized and partially silicated Fusselman dolomite. The west wall is a greenish-gray highly altered rock (composed mostly of sericite and chlorite) also believed to be Fusselman dolomite. The principal ore mineral is galena accompanied by minor amounts of sphalerite.

A shallow test pit was sunk on the Fusselman-quartz monzonite contact south of the main workings. At this place small amounts of magnetite and hematite occur as bedding replacements of the dolomite. Numerous other prospect pits are located in the area surrounding the Lindy Ann prospect. Several test pits to the east and south show minor sulfide mineralization. Two prospects, located in a large xenolith of silicified carbonate rock in the quartz monzonite stock, about three-quarters of a mile to the south of the Lindy Ann, expose only a minor amount of galena and some barite. These occurrences are considered to be of minor importance.
