encountered, on one of which the shaft was sunk 225 feet in 15 to 

 18 feet of ore with a northwest strike. On the hanging side, separated 

 by 15 feet of schist, is a second body which was drifted on for 90 

 feet in a northeast direction and for 60 feet at right angles thereto. 

 It was developed by later operations that the vein in which the 

 shaft is located and the overlying ore body are connected on the 

 northwest side by a band of ore 10 feet thick. It seems likely that 

 the ore in this locality has been folded subsequent to its deposition. 

 Recently a series of prospect pits has been made to the southeast 

 of the mine between there and the highway. A thickness of 30 

 feet of ore is here indicated. The pjvite is of a different type than 

 seen in most of the mines. It is conspicuously banded in alternate 

 layers of coarse and fine material. Some specimens are practically 

 pure sulphides and the average content of the run of mine is well 

 over 25 per cent sulphur. 



Keene-Antwerp deposits. One of the most persistent belts in the 

 region is along the line of the railroad between Keene station and 

 Antwerp, paralleling the railroad on the west and lying along a well- 

 defined valley which is defined by low granite ridges on the east side 

 with a more general sloping ridge opposite, usually of limestone. 

 The belt is about 5 miles long and is composed of successive bands 

 of p3T-ite schist which occur at slightly variant horizons. The rich 

 portions of the schist that occur here and there afford promising 

 ground for prospecting if not actually for mine developments. Some 

 of these richer occurrences are on the Caledonia, Keene, Morgan, 

 Wright and Dickinson properties, all of which contain hematite 

 ores that have been worked on a larger or smaller scale in years 

 past. On the northern end the pyrite occurs mostly in finely divided 

 condition distributed in a schist composed of quartz, feldspar and 

 chlorite which forms one of the walls of the hematite deposits. 

 Samples of the ores of this type show on' analysis 20 per cent sulphiu: 

 or a little more. In the middle section of the belt there is more 

 of the coarse secondary pyrite which occurs in veinlets and bands 

 that intersect the schist. Such material is not only higher in grade 

 but there is more suitable material for concentration. The individual 

 bodies measure from 15 to 20 feet wide as shown on the surface 

 and can be followed for several hundred feet in places without 

 apparent diminution in size. Up to the year 19 18 practically no 

 work had been done on these deposits and their extent seems to 

 have escaped the attention of those engaged in mining in other 

 parts of the district. The development operations have been under
