MINERAL RESOURCES. 695 



UNNAMED PROSPECTS. 



Only a short distance northwest of the Queen Anne are some shallow holes 

 which show a good deal of copper stained material. 



Some diggings on the slope above these are too shallow to show other ma- 

 terial than the surface outcrop. Farther northwest, between the old Fort 

 Quitman and the mountain slope, a number of holes (Baker's prospects) are 

 abandoned. None of them are over twenty feet deep. The outcrops are 

 siliceous iron bowlders and ferruginous decompositions of the granite, in some 

 cases in contact with serpentinous dykes. The material on dump is partly 







solid, partly porous, silico-ferruginous, with quartz, heavy iron ore pieces, 

 decomposed bronzite, and even thoroughly kaolinized feldspar. Still farther 

 northwest, one of Baker's shafts in the flat at the foot of the mountains is 

 sunk to a depth of twenty to thirty feet, in decomposed granite, colored a 

 bright red by oxide of iron. Another shaft about forty feet up on the moun- 

 tain slope on a contact between granite and talcose rocks, both strongly col- 

 ored by iron and including a ferruginous gangue. I could not ascertain if 

 any assays were made. The prospects are encouraging, but no assessment 

 work for 1890 had been done to the middle of September. 



About three hundred yards south of the Queen Anne, half way up the 

 mountain slope, on contact between greenstone and porphyritic material, in 

 a gangue of red and brown, partly spongy, partly solid iron silicates, a vein 

 of carbonates and pyrites of copper begins to show, and was followed down 

 a few feet between the well defined walls, and several hundred feet below 

 that a shaft is sunk to about thirty-five feet. I found on dump, besides 

 greenstone and porphyries, copper pyrites, carbonates of copper, quartz, gar- 

 nets, and a number of indefinite mineral specimens. Good assay results are 

 claimed for the material of these diggings, seemingly of select specimens, but 

 I can not but pronounce the prospect encouraging. No assessment work for 

 1890 was done up to the middle of September. 



BIG GULCH, OR SILVER KING, DISTRICT. 

 SILVER KINO. 



The outcrop is siliceous iron and iron stained surroundings. The lead is a 

 contact gangue between limestone and porphyritic rock; the ore is silver 

 bearing galena and argentiferous siliceous iron, more or less oxidized. A 

 number of shafts, the deepest one hundred and fifty feet, are sunk only a few 

 feet from each other. (The purpose of this is incomprehensible, unless it 

 was to spend money.) With the exception of the assessment work nothing 

 was done up to the middle of September. Some ore was shipped, until the 

 work was stopped for want of money.
