however, been opened by No. 3 shaft, which are sufficient to prove that ore

ciimax mine. The Climax claim is parallel to and adjoins the Amie on 

 the east. The structural conditions are, however, somewhat different in the 

 two claims. The ore horizon is still split up into several parts, but, owing 

 to the erosion of the crest of the anticlinal fold, which runs northeastward 

 along the east boundary of the Climax claim, a much greater proportion of 

 the ore horizon has been eroded off the area of the claim, and the outcrop 

 of what remains runs northeastward nearly parallel to its side lines. 



The mine has been worked only intermittently and without much 

 system, and, as a considerable portion of the workings were inaccessible at 

 the time of visit, information in regard to them could only be obtained by 

 word of mouth, and leaves much to be desired in point of completeness and 

 reliability. The general outlines of the structure were, however, sufficiently 

 well determined by the examination of those workings which were acces- 

 sible, and the uncertainty exists mainly with regard to details of ore dis- 

 tribution. 



The mine workings consist of two disconnected groups, a southern and 

 a northern, the former of which followed the eastern extension of the Amie 

 body, the latter the western extension of the Dunkin body. Between these 

 are the contract or leased workings, which, as their name implies, were 

 worked by other parties under leases, of which no plats could be found, and 

 about which little information could be obtained. 



The southern workings are opened by shafts No. 3 and No. 5, shafts No. 

 4 and No. 6 having been sunk independently to explore the ground further 

 south and not connected with these workings. Of No. 6 it is only known 

 that it was sunk through 160 feet of Wash and reached a body of iron 

 vein material in the top of the White Limestone. Shaft No. 4 cut two 

 bodies of vein material, which are probably part of the lower ore horizon 

 of the Amie mine, before reaching the White Limestone. It would seem 

 probable that the drifts from this shaft might have cut the porphyry dike. 

 Unfortunately at that time miners made no distinction between White and 

 Gray Porphyry, and no definite information on that point could be obtained. 



1 Since the close of field-work a considerable body of rich ore is said to have been opened by the 

 Detr Lodge shaft, which is situated near the Climax line, not far from the Virginius shaft.
