A former F(fluorspar)-Ba(baryte)-Mn occurrence mine located in sec. 7, T24S, R7W, NMM, about 10.5 miles S75E of Deming, S of state route 549 and Interstate highway 10, on private (patented) land within a Bureau of Land Management administered area. Discovered by Dr. Jesse T. Duryea in 1918 and first produced in 1919. The Spar group of claims were patented in 1925 by Duryea. The property consists of 6 patented claims, Mineral Survey No. 1930, covering about 120 acres. Owned and operated by the General Chemical Corporation (1951- ). Owned by the Allied Chemical Corporation (100%), Colorado (1960-1974 & beyond ?). MRDS database stated accuracy for this location is 100 meters. Closed in 1951.
Mineralization is hosted in Pliocene volcanic breccia (agglomerate). The ore body strikes N00S and dips 75E at a thickness of 2 meters, width of 45 meters, and a length of 50 meters. Ore body No. 1 is a fissure vein; No. 2 is breccia fill & tabular, and No. 3 is irregular and in a shear zone. The primary mode of origin was hydrothermal activity. The primary ore control was fracturing and the secondary was faulting. Wallrock alteration is slight. The mineralization occurs in several veins up to 6 feet thick. Local rocks include upper Tertiary sedimentary units.
The mineralogy of the veins is identical; fluorite is the ore mineral, accompanied by manganese oxides, barite, calcite, and quartz. An examination of ore specimens on the dumps revealed that the probable paragenesis of the ore was an initial stage of fluorspar, barite, calcite, and quartz, followed by recurrent movement along the veins, and then deposition of the manganese oxides in a final stage.
The veins range from the vanishing point to as much as 6 feet thick; the average was estimated to be 2 feet. The CaF2 content of the ore was estimated visually to range from 20 to 60 percent.

Workings include surface and underground openings with an overall depth of 45.72 meters. Workings reported in 1961 consisted of 1 vertical shaft, 2 inclined shafts and numerous pits and trenches.
The two inclined shafts were sunk approximately 100 feet apart on a vein that strikes due north and dips 75Β° E. This vein has been stoped thoroughly to the surface near the inclines. The vertical shaft was sunk about 150 feet east of the northernmost incline. Another north-striking vein, but dipping only 50Β° E., has been mined midway between, and north of, the two shafts. The third vein strikes N. 40Β°-50Β° W. and dips steeply to the northeast. It lies 100 feet northeast of the vertical shaft but is terminated against the vein that dips 50Β° E.
Four or five carloads of metallurgical-grade fluorspar was reported to have been shipped prior to 1937 (Talmage and Wootton, 1937, p. 77).
