NEW DISCOVERY MINE. 463 



east of the Little Chief, which separates it from the above claims. This 

 and the Little Pittsburgh were the first mines worked in this region, and 

 at the time of examination the larger ore bodies had been stoped out and 

 the stopes were filled up, so that but imperfect data could be obtained with 

 regard to them. The ore body was nearly continuous on a north-and south 

 line from the Carboniferous ground to New Discovery No. 2 shaft. It 

 consisted mainly of sand carbonate, with chloride of silver, and had an 

 unusual amount of barite in the gangue. This ore occurred mainly in the 

 upper part of the ore horizon, resting in general on chert, with barren iron 

 and clay below. This same upper ore body also covered a considerable 

 area northwest of No. 2 shaft, and was expected to prove continuous over 

 the greater part of the claim in that direction. As it approached No. 4 

 shaft, however, it gradually gave way to a mass of chert, which sometimes 

 occupied the whole horizon, and which along the Vulture line was overlaid 

 by a considerable body of lime-sand and unreplaced dolomite. On this 

 northwest line a few small, scattered bodies of rich ore were found, but just 

 to the northeast of it is the barren zone, already noticed in the Chrysolite 

 ground, which seems to occupy a trough in the formation, the ore horizon, 

 represented by comparatively barren vein material, descending towards its 

 axis from either side These descents are sometimes so abrupt as to suggest 

 a slight movement of displacement. To the southwest of this line the ore 

 bodies, which are very irregularly distributed, extend up to the Wash. They 

 follow two radiating lines from the main ore body, the one in the direction 

 of No. 1 shaft, the other intermediate between that and the drifts running 

 to No. 4. In either case the ore bodies descend to the southwest, which 

 would at first seem a contradiction to the statement that the formation has 

 a general dip northeast. The fact is, however, that the rock-surface, like 

 the surface of the ground, descends here towards Little Stray Horse Creek, 

 and these ore bodies, which are all that erosion has left, belong to the 

 lower part of the ore horizon. It therefore suggests itself that, if this lower 

 portion had been thoroughly prospected in other portions of the mine, other 

 ore bodies might have been found. Owing to the imperfection or want of 

 surveys, it is impossible to say whether this has been done or not.
