698 TRANS-PECOS TEXAS. 



EAGLE FLAT CLIFF. 



On the northeast side are some prospects in quartz between talcose schists; 

 none of the shafts reaching a depth of twenty feet. The quartz leads are two 

 to three feet wide on the surface, rapidly widening out deeper down, and 

 traceable across the hills. The quartz is strongly colored by iron and shows 

 copper stain. No reliable assays of this material were made, but it is claimed 

 that it contains gold, which is not improbable, judging from the character of 

 the quartz and of the country rock. 



Similar quartz leads are more fully exposed on the surface upon the north- 

 ern slope of the Carrizo Mountains, also in talcose schists. With the excep- 

 tion of a hole about three feet deep, there is no prospect, but in the Carrizo 

 Mountains, three miles south of Allamore Station, Texas and Pacific Railway, 

 a number of prospect holes are sunk in talcose schist, on a strongly ferrugi- 

 nous outcrop with copper stain. The prospector claims gold and silver as 

 assay results. 



Of an iron lead close to the railroad, about four miles east of Allamore, 

 some, mostly oxidic, iron was shipped to be used as flux. 



A number of small diggings, hardly scratching the surface, may be found 

 in this neighborhood, all in crystalline schist, partly on ferruginous outcrops, 

 partly on quartz.

THE HAZEL MINE. 



The Hazel mine is located at the foot of the cliff. The outcrop is copper 

 stain and limespar in a fine-grained red sandstone. The gangue material is 

 a more or less siliceous limestone with a pay streak of silver bearing copper 

 sulphides, mostly copper glanz, silver chlorides, and native silver, with occa- 

 sional native copper. The thickness of this pay streak varies from an inch to 

 a number of feet (last winter about twelve feet). The gangue has no walls 

 proper, but changes gradually into the red sandstone in which the fissure runs, 

 and is frequently impregnated with sulphides of copper and silver. 



Over two hundred car loads of ore were shipped from this mine, and vast 

 quantities of low grade ores are on dump, though the work done up to the 

 present time was confined more to shafting and drifting to develop, than to 

 the stopping between the levels. The deepest shaft is between five and six 

 hundred feet, at which depth the gangue, which at the two hundred feet level 

 is over thirty feet, contracts to a few feet, with a pay streak of about two 

 inches of ore yielding about thirty ounces to the ton. There are no great
