LITTLE CHIEF MINE. 465 



which is here in the Blue Limestone, is assumed to be the same sheet which 

 occurs in the lower White Porphyry at No. 5 shaft, and which is gradually 

 cutting up to a higher horizon as one goes south, reaching the upper White 

 Porphyry in the Lower Henriett ground. 



From the relative elevation of the Blue Limestone in this shaft and in 

 the adjoining shafts to the southeast, the Pearson (S 14) shaft of the 

 Gambetta claim, the Joe Bates (S-26) shaft of the Stray Horse claim, and 

 the Vanderbilt (S 25) shaft, there is evidently a break or a sharp fold in 

 the formation to the east of this shaft. On the section both are assumed to 

 exist, and the fault to be the northern continuation of the Carbonate fault. 

 It must be stated, however, that it has not yet been cut on this ridge, and in 

 so far its existence is a matter of pure hypothesis. There is unquestionably 

 an anticlinal fold here, however, which can be traced northeastward into 

 the Dunkin ground. 



Little chief. This claim is analogous to that of the Evening Star, on 

 Carbonate Hill, in that, being a narrow piece of ground left between two 

 adjoining claims, it included within its area an unusually large proportion 

 of ore-bearing ground. Its width is only 250 feet, instead of the normal 

 300, and the title to part of this was contested by the overlapping of the 

 south end of the Little Pittsburgh claim. The outlines of the full claim 

 are given on the map, as well as the broken line which was adopted as a 

 compromise boundary between the contesting claims. As in the ground 

 previously described, there are two main ore bodies, a southern and a 

 northern, separated by the porphyry dike and an area of bai-ren ground. 

 The porphyry dike does not, however, reach the rock surface, as far as 

 known, and in the western portion of the claim the ore body is continuous 

 over it, and forms a connection between the northern and southern bodies 

 along the Carboniferous and New Discovery lines. Here also, the southern 

 body, at its outcrop immediately beneath the Wash, was the first opened. 

 The original workings were reached through the small shafts Nos. 1, 2, 5,' 

 and 7, and were driven irregularly, following the ore shoots. No. 1 found 

 the ore directly beneath the Wash, at a depth of fifty to sixty feet below 

 the surface, in a thickness of ten to twelve feet. The shaft was afterwards 



1 No. 5, which is the southernmost shaft on the claim, is wrongly numbered on the map No. 3.
