Duluth, which has never worked it but apparently is holding the 

 property as a possible future source of supply. 



In addition to these developed mines there are many prospects 

 and outcrops of the pyrite ores in southwestern St Lawrence and 

 northern Jefferson counties. The beltlike development of the 

 pyritous schists makes for a degree of continuity in the ore-bearing 

 areas as they are traced on the strike that is quite remarkable, 

 although of course there is no absolute uniformity in the enrichment 

 of the material by sulphides. At the same time the work of pros- 

 pecting is greatly facilitated by this characteristic. 



The same belt in which the Cole mine is located extends north- 

 east for 6 or 7 miles, paralleling the Rome, Watertown & Ogdens- 

 burg Railroad for the first 5 miles to a point a mile or so beyond 

 Bigelow. The Hendricks, Styles and Farr shafts are located within 

 this area. 



Another belt extends through Hermon and has been prospected 

 near Ore Bed school, 2 miles northeast of Hermon village. 



A remarkably persistent outcrop of the pyrite schist is found in 

 the towns of Hermon, Fowler and Gouverneur, St Lawrence county, 

 and Antwerp, Jefferson county. It crosses the Oswegatchie river 

 at Hailesboro, from which point it reaches northeast in a nearly 

 straight course to the Barnum school, in the town of Hermon, and 

 southwest to Keene station below Gouverneur and thence along the 

 Rome, Watertown & Ogdensburg Railroad to near Antwerp. Its 

 principal development is in the stretch from near the old Caledonia 

 iron mines just north of Keene to the Dickson mines north of Ant- 

 werp. The pyrite schist is accompanied in this stretch by hematite 

 which also occurs in sporadic bodies elsewhere and which is an indi- 

 cator of pyrite throughout this section. Little or no prospecting 

 for pyrite has been carried on in this belt, although the schist has 

 been well exposed by the iron-mining operations or is found in nat- 

 ural outcrop. In several places, notably on the Keene, Morgan, 

 Wight and Dickson properties, there is a good body of the ore 

 shown which carries above 20 per cent in sulphur. The vein ranges 

 from 10 to 25 feet or more in thickness. The deposit is so per- 

 sistent on the surface that its continuity for a good distance on the 

 dip may be regarded as assured. The ore is coarser in grain in the 

 southwest part on the Wight and Dickson properties than elsewhere. 

 With the railroad close at hand this section seems one of the most 

 attractive in which to prosecute exploration for pyrite. 



In the vicinity of Oxbow, Jefferson county, is another schist belt 

 that has locally enriched bodies that carry around 25 per cent or
