MINERAL RESOURCES OF THE STATE OF NEW YORK IlQ 



based on an ore band that extends for over a mile on a course a 

 little east of north. The band is straight, regular and over a mile 

 in length. Its outcrop is marked by a reddish color, which arises 

 from oxidation of the sulphides that are intermixed in small pro- 

 portions with the magnetite. The deposit is rather thin, not over 

 lo or 12 feet in most places, but no doubt contains a large quantity 

 of ore. On account of the sulphur content it has not been exploited 

 in any large measure, although some ore was produced in earlier 

 years for furnace use, having been roasted on the ground. A 

 sample representing the crude material as mined is stated by Putnam 

 to have contained 52.93 per cent iron, .028 phosphorus and 3.603 

 sulphur. 



The Morehead, Bering and Sloatsburg mines were opened in 

 different bodies that lie in the area between Sloatsburg and Tuxedo 

 lake. The Sloatsburg mine is in Rockland county. None of these 

 has been worked in recent years and little is known as to their 

 extent or as to the character of the ores. 



Altogether t!he resources in the Sterling Lake district are undoubt- 

 edly very large. So far only the richer and more available ores 

 have been attacked, as the concentration of the low grade material 

 has not been attempted; there is no reason to believe that any of 

 the mines have been bottomed and in most instances the supplies 

 have not been seriously drawn upon. In view of its favorable 

 situation and the extent of the resources, the district should take a 

 prominent place in the future mining industry of the State. 



Warwick. A group of ore bodies, on which are located the 

 Rayner, Taylor and Standish mines, now inoperative, lies 2^ miles 

 south and a little east of Warwick, Orange county, on the ridge of 

 gneiss between there and Greenwood lake. The Standish mine is 

 based on a thin seam, not over 2 to 8 feet thick as opened, which 

 can be traced for one-half mile on the outcrop. In one place it is 

 split by a horse of the country rock, a well-laminated biotite gneiss 

 heavily injected with pegmatite. The seam strikes N. 30° E. and 

 stands vertical or inclined at a high angle to the southeast. At the 

 northeast end it is faulted by a dip fault, beyond which the 

 ore is not again in evidence. The magnetite carries some pyrite, 

 but is fairly high in iron. The mine was last worked about 1880 

 by the Parrott Iron Co. 



The Rayner is west of the former, across the highway on a ridge. 

 It is widest toward the northeast where it was opened by a shaft, 

 now caved, and there open cuts show 6 to 10 feet of ore in nearly 

 vertical position. To the southwest along the trend it becomes 

 a double bed through the appearance of a seam of gneiss that increases
