LINDGBEN.] MINES ON WILLOW CREEK. 715 



ore was sloped and milled in 1895. The vein strikes N. 81 W., dips 

 60 N., and shows 2 to 3 feet of decomposed vein matter which, in the 

 pay shoot, yielded, it is said, $38 per ton of free gold. Pockets carry- 

 ing extremely rich ore occurred at intervals. On the west side the 

 vein is said to splinter up in a porphyry dike. 



The Iron Dollar is located a short distance east of the Easter, and 

 is probably the continuation of the same vein. The development 

 consists of short tunnels and surface cuts. A few tons have been 

 milled, yielding $58 in free gold. The vein, which strikes N. 71 W. 

 and dips 60 N., lies in granite with occasional porphyry dikes in the 

 hanging wall. The decomposed ore consists of altered granite, with 

 streaks of arsenopyrite, pyrite, and galena, as well as a little calcite 

 and quartz. A sample of good ore gave 2.50 ounces of gold and 7.15 

 ounces of silver to the ton, a total of $56.68. 



The Judas lies a few hundred feet north of the Iron Dollar, and is 

 at present (1897) being developed by a shaft intended to reach a 

 depth of 400 feet. Excellent ore is reported to have been milled from 

 this vein. The strike and dip are nearly the same as in the Iron 

 Dollar, and the vein shows from 1 to 2 feet of decomposed granite 

 carrying rich seams. 



The Checkmate crops in granite on the south side of Willow Creek, 

 due south of the Judas. This vein is one of the productive proper- 

 ties, shipping ore during the whole summer of 1896. It is reported 

 that 300 tons, averaging $80 per ton, have been shipped. The mine 

 is developed by a tunnel 100 feet long on the level of the creek, giving 

 about 100 feet of backs. The deposit consists of a zone several feet 

 wide of altered and pyritic granite, containing rich seams of heavy 

 sulphides, arsenopyrite, pyrite, blende, and galena. At the time the 

 mine was visited most of the ore came from a seam of solid sulphides 

 4 to 6 inches wide. The strike is 1ST. 84 W. ; the dip to the north. 



A short distance east of the Checkmate is the Silver Spray, from 

 which some good ore has been shipped. The vein is opened by a short 

 tunnel, and strikes east-west, dipping 40 N. The country rock is 

 dioritic granite, with streaks of dark diorite and dikes of diorite- 

 porphyrite. The character and the minerals are similar to the 

 Checkmate. 



A little farther east is the Golden Chest, showing a wide zone of 

 altered and pyritous granite with narrow seams of zinc blende. 



South of Willow Creek, opposite the last-named claim, lies the Red 

 Warrior, the oldest location in the district. No work was done on it 

 in 1896. 



One mile southeast of Pearl, on the summit of a ridge, lies the 

 Leviathan claim. This is developed by a shaft 75 feet deep, and a 

 few tons of rich ore have been shipped. The width of the mineralized 

 granite is 13 feet, with seams of pay ore on both walls. In the con- 

 tinuation of this claim lie the Middleman and the Sacramento, which
