MINKS BETWEEN ALTMAN AND GOLDFIELD. 
403 
muddy streaks 1 to 3 inches wide, which occur at one side or the other of the sheeted 
zone. The material is completely oxidized and, when panned, proved to be very 
rich in gold. 
MURPHY MINE. 
The Murphy mine, also owned by the Free Coinage Company, is situated on 
the Wilson claim about 120 feet southwest of the Mercer mine. The production 
was not ascertained, but has been considerable. The workings consist of a 350- 
foot incline shaft and 7,800 feet of drifting. 
The Wilson vein continues from the Mercer into Murphy ground and is the 
principal vein of the mine. Its character is much the same as in the Mercer, but 
no fluorite was seen. Another vein, practically vertical, of irregular strike, but 
averaging about S. 20° W., branches off on the east side of the main vein. There 
seems to be no crossing, and to the north of the point where the veins come together 
the two seem to unite as one vein. The junction is about 60 feet southwest of the 
shaft at the surface and pitches so that it is about an equal distance northeast at ♦ 
the bottom, becoming more nearly vertical with increasing depth. 
The ore occurs in the seams and fissures and is almost wholly oxidized. By 
screening and sorting about one-fifth of the rock broken is saved as ore and runs 
$30 to $300 per ton. Underhand stoping improves the values of the ore saved, as 
in the Mercer mine. Ore on the Wilson vein was stoped from the Mercer line to a 
point where the values quickly decrease, 15 to 30 feet southwest of the junction. 
The stope reaches from the surface to the 350-foot level, where the shoot practically 
ends. Ore along the junction of the veins was better than elsewhere. The branch 
vein has been stoped 100 feet from the junction from about the 300-foot level up 
almost to the 70-foot level, and work is being done in good ore higher up. The 
occurrence and amount of the valuable minerals are practically the same as in the 
main vein. 
Whether or not there is any relation between this branch vein and the one 
which branches from the Wilson vein in the Mercer workings it was impossible to 
determine. 
PUEBLO MINE. 
The Pueblo mine is located on the claim of the same name and lies well up on 
the western slope of Bull Cliff. It is the property of the Free Coinage Company 
and is being worked under lease. The production of the mine is not large. The 
underground workings consist of a 100-foot incline shaft and two levels represent¬ 
ing about 150 feet of drifting. 
The shaft is sunk on a vein striking N. 55° W. and dipping about 80° NE. It 
is 2 feet wide and is oxidized and brecciated. On account of the decomposition of 
the country rock its character could not be determined. The 50-foot level follows 
the vein on both sides of the shaft. A stope 15 to 20 feet high and 75 feet long 
above the level yielded $15 to $40 values in rusty gold after screening and sorting. 
On the 100-foot level the northwest-southeast vein is crossed 15 feet northwest of 
the shaft by a north-south vein dipping 45° W. Stoping is being done along both 
veins, and oxidized ore running $20 to $40 is being shipped.
