These consist of one tunnel (fig.3) and two shafts (figs. 4-7)which, judging from the volume of dump material, contain the majority of development. The tunnelis 54 ft. in,length and was apparently driven prior to 1914 to test a narrow vein structure. It was abandoned when the vein proved to be uneconomic. The two shafts are open, but dueto their condition were not entered. Shaft no. 7 (fig.6), also known as the "tunnel" shaft, was the center of most of the early (19.10-1916) development. This shaft was164 ft~. deep, nearly vertical, with levels 65 at ft. (the 60 ft. level) andat or near the bottom (the 150 ft. level). The shaft is presently open to 104 ft. below the collar; it is 0 caved at this point and has been, apparently, for some time. This cavingis probably indicative in part of stoping above the 150 ft. level. Heavy ground, however, is known to have been encountered in this shaft." Shaft no. 1 (fig. 7), also known as the "lower" shaft;.was, in 1914, 80 ft. deep with short drifts at the bottom driven to the east and west. This shaft, inclined 265" to the southeast, was the center of activity during the later (1920-37) period. During this time,it was extended below the 100 ft. level where, at 103 ft., a drift was driven to the west a distance of 208 ft. and another to the east 25 ft. Small i lo stopes were developed above each drift Letter from Ed Scarborough to Kathryn Sullivan, 5/12/48. and around the I Fig. 4: View of Lookout Hill looking West.

A sample (Batt # 7 ) from this shear was too low grade to be economic, but an intersection of the two shears at depth could.provide a mineable orebody. Thorman and Drewes do not show an intersection at the surface, nor was one observed by the authors. The andesite third - area for exploration is along the Cretaceous Tertiary granodiorite contact. This contact nearly surrounds the baseof Lookout Hill. Ore has been'mined from near this district.21 The contact in 85 theand areaof the Anita contacton the mines in the northern ..s lope of Lookout Hill nearest the east-west fault/shear zone is 0 most likely to yield good results. ECONOMICS Samples 1 and 3 are representativeof vein material from the Battleship workings. The assays compare favorably with similar samples taken during the early1940's. byU.S. a Bureau of Mines The average of the two NMBM samples assayed: Copper (Cu) Lead (Pb) Silver (Ag) Gold (Au) 21 engineer 1.92% 1.55% 3.67 oz/ton 0.035 oz/ton Lasky, op. cit., plates16 and 21 Average of thirteen USBM samples assayed: CU Pb Ag Au - 1.6% (not determined) - 1.96 oz/ton 0.06 oz/ton - The weighted average of these 15 samples is Cu - 1.64 percent: Ag - 2.19 ounces per ton, and Au0.057 ounces per ton. Lead will probably average about one percent (the average value of the seven New Mexico Bureau of Mines and Mineral Resources samples is 1.05%). The value of this material" is as follows: Cu: 32.8 lb/ton x $.89238/1b= $29.27 Pb: 120 lb/ton x $.38966/1b = 7.79 Ag: 2.19 oz/ton x $15.65/oz = 34.27 Au: 0.0570z/ton x $594.814/02= 33.90 Total Value per ton . $105.23 The above samples and calculations indicate that ores likely to be found in the Battleship mine will be too low grade to ship directly to a smelter (custom smelter charges presently amount to $150.00/ton). To be made economic, the ore would have to be concentrated, probably by means of froth flotation. But it is unlikely that sufficient tonnage will be foundon the Battleship group to finance construction of a suitable mill. Thus the Battleship group by itself appears to have little present value. The economic picture could 22 Metals Week quotations,E & MJ, Vol. 182, No. 1, Jan. 1981 change rapidly however with;the establishment of a nearby custom milling operation. Three mills are presently standing idle in the area and are suitable for such an enterprise: Asarco's andBariteof America's two mills just north of Deming and Federal Resources mill nearby at the Bonney 2 3mine.
