50 KANSAS CITY REVIEW OF SCIENCE. 



feet crystals of that mineral, free and also fine crystals of pyrites, and, what is 

 quite uncommon in this camp, these pyrites will give good assays in silver. 



On the surface, about 300 feet south and parallel with the quartz outcrop of 

 the Franklin, is a large dyke of syenite toward which this quartz lode dips, and 

 towards the bottom of the shaft, jutting through the Porphyry, (properly speaking 

 Trachyte) blocks of this syenite have been met, indicating that somewhere, not a 

 great distance farther downward, there is a place of contact between the two 

 dykes of syenite and quartz. At this place of contact will probably be found a 

 regular vein of richer mineral pitching downwards in addition to what the quartz 

 may contain in pockets. 



The present condition and past results obtained in this mine reflect great 

 credit on the working management, and give all who are acquainted with it 

 confidence that the future workings will not only give much pay mineral pro- 

 duced by careful and economical supervision, but also prove a source of large 

 profit to all of the owners. Two shifts of men are employed, twelve in all, with two 

 boys to operate the mules, constant work being kept up, except from mid-night 

 of Saturday until Monday morning, and during this idle time only forty to fifty 

 barrels of water accumulate in the shaft. 



While the products were carbonates or free milling ore, it was treated at the 

 Pennsylvania Company's Reduction Works, at Rosita. Afterward, becoming 

 too refractory for their process it was shipped by wagons to Messrs. Mather & 

 Geist, Pueblo, Colorado. The road from here to Pueblo is down hill most all of 

 the distance, (fifty miles) through Hardscrabble Canon. Freight is $8.00 to 

 $10.00 per ton, according to season and condition of roads. During the last 

 two months over twenty tons of mineral have been shipped, (leaving about three 

 tons on hand at this date) and giving mill returns of 121 ounces to 174 ounces 

 in silver, or an average of about 142 ounces. No expense is incurred for sorting 

 this ore, as when a pocket is opened it all comes in a body, and is merely dried 

 by the ore-house stove and sacked ready for shipment, each sack averaging about 

 140 pounds. As an instance of how free this mineral is to mine, in the pocket 

 mentioned as being on the north wall, the second day after it was opened, one 

 man in one shift of eight and one-half hours took out over two tons of pay 

 mineral. 



I have endeavored to be thus minute in the description of this mine, as well 

 as exact, from the fact that it is for this camp a remarkable ore-body, and also 

 that it is a successful development where many others would have failed in pro- 

 ducing pay. I am under obligation to Mr. Thurman, General Manager, and 

 Mr. Williams, Foreman, for the facts and facilities for observation, the results of 

 which I have given.
