in silico-ferruginous matrix, with strains of uranium. One or two car loads 

 of ore were shipped. It is probably located on railroad land. It has been 

 abandoned. 



UNNAMED PEOSPECTS. 



On the east slope of the same hill another prospect hole, showing material 

 of seemingly similar combination, with more plain uranium stains. No assays 

 have been made of these ores, and the shaft has been abandoned. 



There are a number of shallow holes on iron stain in this neighborhood on 

 both sides of the railroad, some of them sufficiently promising to justify pros- 

 pecting. 



On the northern slope of the first range of the Quitman Mountains is the 

 Correales prospect at the foot of the mountains. The gangue outcrop is a 

 strongly ferruginous decomposition of the granites. It changes in greater 

 depth to a more siliceous material, with walls appearing more distinctly, silver 

 bearing galena in thread-like impregnations, and small pockets of silver bear- 

 ing galena. The depth of the shaft is about fifty feet. 



Higher up on the mountain slope are a number of shallow holes on the 

 same and on parallel leads, some of them showing galena at the outcrop, with 

 ferrugiifous decompositions. No work was done here last year. 



On the eastern slope of the first Quitman range are a number of shallow 

 prospect holes on ferruginous stains in limestone and on ferruginous decom- 

 positions of contacts, which it is claimed carry gold. This shaft has been 

 abandoned, or at least it was not worked last year. 



BONANZA DISTRICT. 

 BONANZA MINE. 



Near the road from Sierra Blanca to the Bonanza mine, on an isolated 

 granite hill, a prospect hole has been put down about ten feet on a ferrugin- 

 ous decomposition of the granite, showing a beginning vein of iron stained 

 and copper stained material, with occasionally small specks of galena. No 

 assays were made for precious metals, and the prospect has been abandoned. 



The north side of the valley, forming what I call the Bonanza district, 

 shows only a few shallow prospect holes, although the leads on the slopes on 

 the south side of this valley may be traced over the west by any halfway ex- 

 perienced prospector. 



On the south side of the valley, and on the northern slope of the second 

 range of the Quitman Mountains, we find the Bonanza mine. The outcrop 

 of the lead is a strongly siliceous out blow in contact with granitic and por- 

 phyritic rock. The working shaft, nearly perpendicular, follows the vein
