In the interval between Edwards and the Bahiiat prospect there 

 have been several discoveries of ore which, however, have not been 

 sufficiently prospected to reveal anything definite as to their extent. 

 They indicate that the mineralization follows a fairly definite zone 

 parallel and in proximity to the talc deposits. 



The Balmat occurrence is described briefly by Emmons in the 

 report already referred to as '* a remarkable occurrence of the sul- 

 furets of zinc, lead and iron in about equal proportions .... 

 The direction of the vein is north-northeast and south-southwest 

 and the width about 8 inches, but not well defined. The sulfurets 

 traverse a bed of serpentine 40 to 50 feet wide. The occurrence of 

 zinc intermixed with lead is not favorable to the reduction of the 

 latter." There are two shafts on the ore body about 1000 feet apart. 

 The outcrop of the ore where it is revealed shows a vein or band up 

 to 3 feet thick. Near the south shaft a short adit has been driven 

 into the ore from the side hill, the only part of the workings now 

 accessible, and shows the vein at this point to be from 4 to 5 feet 

 thick. There is much more galena in this occurrence than at 

 Edwards and usually more pyrite. 



Another ore locality in the southwestern section is on the lands 

 owned by J. H. McLear, south of Little York and near Sylvia lake. 

 The deposit was originally opened with a view to the working of 

 iron ore wdiich occurs in the form of specular hematite. Some of 

 it was used in the FuUerville furnace nearby. The hematite occurs 

 in a lens of uncertain size, some of it being nearly pure and other 

 parts charged with pyrite and blende. The sulfides are specially 

 developed along one of the walls. Specimens from this part have 

 assayed above 20 per cent zinc. There has been no recent work 

 done on the deposit. 



From the present stage of development there is insufficient evi- 

 dence to base any prediction as to the possibilities of the district as 

 a producer of zinc ore. It is evident, however, that a small output 

 is assured by the results obtained at Edwards where thus far only 

 a single outcropping has been attacked. If the developments there 

 continue as favorable during the coming season as they have been in 

 the past they will go far toward proving the persistence of the 

 deposits in depth which is of most importance to the future of 

 the district and about which least is now known. In the case of 

 such issue there will be much encouragement, also, for the exten- 

 sion of exploration to other parts of the mineralized area. Though 

 the deposits are narrow as compared with those found in the 

 important zinc-producing districts of other states, they possess an
