BELLE PROSPECT. 



At the Belle prospect two shafts have been sunk to the depth of about fifty- 

 feet. The gangue is in contact between limestone and porphyritic rock. The 

 ore is similar to that of the Silver King, though seemingly carrying more 

 carbonates, oxides, and copper stain. 



j. Harrison's prospect, 



About one-fourth of a mile west of the Silver King, high up on the slope, 

 also in contact between porphyry and limestones, shows galena and a ferru- 

 ginous gangue at a depth of forty feet. A shaft dug in the valley by the 

 same prospectors carries galena in a contact gangue, with well defined walls, 

 at a depth of twenty-five feet. No work has been done lately. 



EUREKA SHAFT. 



The Eureka shaft is on the same lead with the Silver King; shows no ga- 

 lena at a depth of seventy five feet. How far the material on dump is silver 

 bearing has never been ascertained by assays. No work was done to Sep- 

 tember 25. 



EMMA CLARK TUNNEL. 



A tunnel of about one hundred and fifty feet in length (Emma Clark) has 

 about a ton of ore on dump. Other smaller tunnels and shafts, though some 

 of them show promising indications, even ore, are abandoned. Among them 

 is the May Belle and some diggings of Kyle Brothers. 



ZIMPELMAN'S PASS DISTRICT. 



On the pass where it crosses the crest are some shallow holes between lime- 

 stone and green garnet rock. There is a quantity of strongly copper stained 

 material on the dumps. No work has been done here in the last two years. 



A number of shafts are found on a very large iron outcrop. I could not 

 ascertain the depth of the shafts, but judging from the dump pile they may 

 be seventy-five or one hundred feet deep. The gangue is strongly iron bear- 

 ing, with occasional galena strings and small pockets. The value, as far as I 

 know, was not ascertained at all, or at least only superficially, by assays. N o 

 work has been done here for the last two years. 



There are a number of diggings in the valley on both sides of the moun- 

 tain range. With the exception of one which is sunk on a quartz outcrop, 

 all are on iron outcrops in contact between granitic and porphyritic material. 

 Farther southwest, on the road side of the Quitman Mountains, we find the
