MINERAL RESOURCES. 691 



Black Hills of Dakota, I had ascertained and stated the presence of tin and 

 wolframium, nearly always associated with tin, long before any larger leads 

 were discovered. 



HUNTER DISTRICT. 



HUNTEK MINE (OR RATHER PROSPECT). 



Outcrop, silico-ferruginous, in contact between crystalline limestone and 

 granitic porphyry. One shaft with well showing walls, timbered where neces- 

 sary. Ores, a combination of iron, copper, lead, zinc, nickel, uranium, silver 

 bearing, with traces of gold. Lower down, zinciferous; at the bottom of the 

 shaft, one hundred and fifty feet, zincblende. 



Ores partly oxidic and carbonic, partly sulphides. No thorough analysis 

 was made. Shipped some ore. Claimed to be on private land located by Mr. 

 Barlow, defunct, of Sierra Blanca. No work done for two years. 



A number of shallow diggings in the flat on the same and parallel gangues, 

 dipping nearly perpendicular and following the general east- west strike, like 

 the main prospect, show veins from one-half to three inches thick, of seem- 

 ingly the same combination as that of the main prospect. Besides these dig- 

 gings in the flat there are a number of holes, mostly mere .surface* scratch- 

 ings, on the northern slope of the Quitman Mountains, opposite the Hunter. 



BONA (PROSPECT). 



One-half mile north of the Hunter. Outcrop, siliceous iron, in contact 

 with lime and porphyritic rock. Lead, silico-ferruginous, with silver bearing 

 galena in streaks and pockets; some nickel with the iron. A rough shaft 

 about thirty-five feet deep. The vein will probably carry the same combina- 

 tions as the Hunter in greater depth. Some ore was shipped, but the work 

 has been abandoned. 



About three-fourths of a mile northeast of the Bona, across the railroad, a 

 nameless prospect, on strongly ferruginous outcrop in brecciatic conglomerate, 

 drifting forty feet and ten feet into the mountain slope. Strongly ferrugin- 

 ous material on dump which has not yet been analyzed. This has been aban- 

 doned. 



STOKES PROSPECT. 



About two miles northwest of Etholen, on the south side of the railway, a 

 number of holes, the deepest of which is about twenty-five feet. Siliceous 

 iron outcrop in contact with lime and porphyritic rocks, impregnations, and 

 smaller pockets of argentiferous galena; also sulphides and chlorides of silver
