716 IDAHO MINING DISTRICTS. 



have the same east- west strike. Both of these claims have shipped 

 some rich ore, containing much galena. The pure galena, assays 8 

 ounces of gold and 67 ounces of silver to the ton. The developments 

 are slight. 



The Friday is located on a flat 100 feet south of the Leviathan and 

 is developed by a 100-foot shaft and drifts on the vein. Thirty tons 

 of ore are said to have been shipped and some rich surface ore has 

 been milled. The deposit shows 8 feet of altered granite, with a seam 

 of heavy sulphides on the foot and hanging -walls. The ore contains 

 pyrite, arsenopyrite, and blende, with much calcite. This vein is said 

 to be nearly vertical. The mine was not accessible during the present 

 examination. 



Beyond the claims mentioned, for a distance of about 1,000 feet, there 

 are but few locations, but a number of strong veins are found on the 

 summit of the ridge separating Willow Creek from Rock Creek. 



Beginning on the north, the Emmett vein is located near the summit 

 of Crown Point Hill, on the southwesterly slope. Good ore is reported 

 to have been found in this claim and shipments were made during 

 the winter of 1896-97. An incline shaft is sunk to a depth of 100 feet. 



The Ida lies on the Rock Creek slope, at an elevation of 4, 700 feet, 

 and appears to be a wide vein in a dike of mineralized porphyry. It 

 is developed by 175 feet of tunnels and shaft, and excellent assays 

 have been obtained from average samples. The Blaine, on the 

 Willow Creek side, a short distance north of the road to Rock Creek, 

 is a promising prospect from which some ore was shipped in 1896. 

 The Alexander, located on the divide, showed some good ore, a brown 

 decomposed mass containing lead carbonate and milling $40 per ton. 

 The vein is 4 feet wide, striking N. 74 E. and dipping north. 



The Birthday, a few hundred feet south of the Blaine, has produced 

 some rich shipping ore, composed of solid pyrite, zinc blende, and 

 galena. 



The Silver Wreath lies on the Willow Creek side, three-fourths of 

 a mile southeast of Crown Point Hill, and is opened by a crosscut 

 170 feet long, cutting the vein at a depth of 75 feet. The croppings 

 show distinctly by quartz, colored greenish by arsenic. The strike is 

 N. 79 E. and the dip steep to the north. The deposit consists of a 

 zone of decomposed dioritic granite, 8 feet wide, containing seams of 

 the usual minerals. Some ore shipped yielded $40 per ton. 



The IXL is situated on the Rock Creek side, three-fourths of a mile 

 east-southeast of Crown Point Hill. An incline shaft is being sunk 

 on this vein, and has at the present writing attained a depth of 200 

 feet. The vein, which strikes on an average northeast and dips 

 50 N. , is contained in granite with a dike of granite-porphyry in the 

 hanging wall. Four feet of brown decomposed vein matter are shown 

 in the shaft. About 25 per cent of the total value is in free gold, and, 

 according to average samples, there is a considerable body of medium-
