Minerals Not Commercially Important. 



In addition to the minerals which have already been mentioned 

 there are many deposits in New York which are not at present of 

 commercial importance. These may be roughly classified as 

 metallic minerals and non-metallic minerals. In the first class 

 are iron pyrites, arsenopy rite, chromite, chalcopyrite, cuprite, 

 galenite, cerusite, sphalerite, wad or bog manganese, millerite 

 and molybdenite. The galenite and pyrites have respectively 

 yielded small quantities of silver and gold at certain places, but 

 at no locality in New York have enough of the precious metals 

 been found at any time to pay for the expense of extracting 

 them. From time to time capital is invested for the purpose of 

 gold or silver mining in New York, but always without practical 

 results. The experience of 50 years has shown that neither in 

 New York nor in England have either of the metals been found 

 in paying quantities. 



The f. llowingt is a list of the principal localities at which these 

 various metallic minerals are to be found : 



Iron, Sulphur, Arsenic. 



Pyrite, iron pyrites, bisulphide of iron. — Anthony's nose, Mont- 

 gomery, Westchester county, mine formerly worked ; Phillip ore 

 bed, Phillipstown, Patterson, southeast of Carmel and near 

 Ludington mills, in Putnam county ; with galena at Wurtsboro 

 lead mine, Sullivan county ; Flat creek, Montgomery county ; 

 near Canton, St. Lawrence county, in extensive beds ; Duane, 

 Franklin county, large bed ; Martinsburg, Lewis county ; 

 Eighteen-mile creek, Erie county, and many other localities, 

 sparingly in rocks. 



Arsenopyrite, mispickel. — Near Edenville, Orange county, with 

 arsenical iron and orpiment, in a vein in white limestone ; near 

 Pine pond in Kent, and near Boyd's Corner, Putnam county. 

 These localities have been opened, but not worked for arsenic.
