LINDQBEN.] QUARTZBURQ-QRIMES PASS GOLD BELT. 691 



The Gold Hill vein. This is probably the continuation of the 

 Ebenezer vein, though it has not been traced across Fall Creek. It 

 is continuous from the Newburg, on the divide between Fall Creek 

 and the west fork of Granite Creek, to at least some distance east of 

 Quartzburg. 



The Newburg claim, at an elevation of 5,000 feet, was worked exten- 

 sively by surface sluicing during the early days, then abandoned, and 

 again located. It is developed to some extent by tunnels aggrega- 

 ting several hundred feet in length. The vein consists of a shattered 

 and decomposed zone in a belt of quartz-porphyrite, and reaches a 

 width of 70 feet. Narrow seams extremely rich in gold traverse this 

 shattered zone, giving to the whole an assay ^lue variously stated 

 from $4 to $12. The ore body is evidently extensive. 



The Homeward Bound, Elizabeth, and Mayflower adjoin the New- 

 burg on the northeast across West Fork. Considerable surface work 

 with sluices and arrastreshas been done on them. The vein is about 

 5 feet wide, and is said to contain sulphurets in large quantities in 

 depth. A narrow streak of quartz- porphyrite follows it. The Con- 

 federate and the Dunlap adjoin Gold Hill on the west, and have a 

 strike of N. 65 E. The developments are not extensive, but some good 

 ore is reported to occur on them. ' 



The Gold Hill and Pioneer claims constitute the most important 

 quartz mine in the Idaho Basin, and the only one which has been 

 extensively and systematically worked, having been in operation with 

 short interruptions since 1864. The Gold Hill was first worked and 

 yielded for a long time ore averaging $20 per ton. It was first 

 exploited by tunnels on the northeastern side of Granite Creek, but 

 in 1875 work began below water level in a shaft just below Quartz- 

 burg on the eastern branch of the creek, the total depth attained 

 being 400 feet. In late years the Gold Hill vein has been abandoned 

 and work concentrated on the Pioneer, a claim adjoining on the south- 

 east. The total amount extracted from the Gold Hill and Dunlap 

 claims from 1869 to 1894 is stated to have been $1,280,000, and the 

 production from the Pioneer claim from 1884 to 1895 is stated to have 

 been $498,000. The total production of the claims mentioned, all of 

 which was not recorded, is believed to have been at least $2,225,000. 



In the mint reports the following data are found : Raymond's report 

 for 1872 states that Gold Hill produced $300,000 since September, 1869. 

 In 1881 it is stated that 150 tons of ore from the Gold Hill yielded 

 $25,000 in gold. In 1883 the Gold Hill produced $76,800; in 1884 the 

 production was $50,000. The property was equipped with a 25-stainp 

 mill in 1875. No work was in progress in 1896, pending a sale of the 

 mine. The Gold Hill vein is a well-defined quartz vein with an aver- 

 age strike of N. 70 E., and a dip of 70 S. The foot wall is generally 

 sharp and well defined and consists of granite. In the hanging wall 

 lies a dike of quartz-porphyrite several hundred feet wide, described
