tricts, and in some localities it is in sufficient quantity to 

 even constitute a considerable proportion of the whole rock 

 mass. The quartz occurs prevailingly in veins which ex- 

 hibit considerable variety of form and are as a rule small 

 and non-persistent, but range in size from mere threads to 

 masses several hundred feet in length, but in most p aces 

 less than 10 feet (3 m.) in thickness. 



The quartz veins are characteristically but slightly 

 mineralized; pyrite and more rarely magnetite occur in 

 places in sufficient quantity to produce a reddish coloration 

 on the exposed and oxidized portions of the veins, and in 

 a few places the quartz contains particles of galena, chal- 

 copyrite, and native gold. 



Often fair, and occasionally even high, assays are ob 

 tained, but, in most cases, it is not known, even approxi- 

 mately, what average amounts of gold the quartz con- 

 tains. From the various properties that have been exam- 

 ined, however, it is concluded that the gold is always either 

 associated with metallic sulphides, or is at or near the 

 contact between the quartz and schists; in the latter case 

 the gold is found in both vein material and wall rock. 



A considerable numbei of quartz claims have been 

 located in the district. Among the more promising proper- 

 ties now being held, and those on which the most energy 

 has been expended are: — the Lone Star group, near the 

 head of Victoria gulch, a tributary of Bonanza creek; the 

 Violet group, situated along the divide between Eldorado 

 and Ophir creeks; the Mitchell group on the divide be- 

 tween the heads of Hunker and Goldbottom creeks; the 

 Lloyd group and neighbouring claims situated along the 

 divide between the heads of Green gulch and Caribou 

 gulch, tributaries respectively of Sulphur and Dominion 

 creeks ; and several groups of claims on Bear creek near 

 where joined by Lindow creek. Of these the only pro- 

 perties on which any development has been performed, 

 other than the necessary assessment work, are the Lone 

 Star and Violet groups. 



No work has been performed on the Violet group for 

 several years, but it is claimed that over $60,000 had been 

 spent in developing the property previous to 19 10. 



On the Lone Star group several hundred feet of work 

 has been performed in the form of open-cuts, trenches, 

 shafts and tunnelling. A four-stamp Joshua Hendry mill 

 has also been erected on the property, and a gravity tram- 

 way 3500 feet (1064 m.) long has been constructed to convey
