No. 5 mine next northeast to No. 4 has been closed down for 

 several years. 



The mine of the Uniform Fibrous Talc Co. is situated just west 

 of Talcville on a slight prominence known as Wintergreen hill. It 

 is opened by a shaft close to the Oswegatchie river. This company 

 began operations in 191 1 and the mine is practically a new develop- 

 ment from the surface. The deposit appears to be nearly in the 

 same horizon as that defined by the United States and No. 25 mines 

 at Talcville. The shaft is vertical for the first 90 feet then follows 

 the northwest dip of the talc. The body is said to have a width 

 in places of 30 feet or more and yields a white fibrous talc. The 

 mill is situated close to the mine and both are operated by electric 

 power obtained from the company's hydro-electric station on the 

 west branch, above its junction with the east branch of the Oswe- 

 gatchie river. 



The mine formerly worked by the Ontario Talc Co. is located 

 about I mile below Fullerville on the west branch. A shaft 

 follows the seam of talc which dips at an average of 45° northwest 

 and in most parts ranges from 12 to 18 feet in thickness. The tale 

 is mostly of fibrous nature although carrying some of the foliated 

 variety and is of a good white color and soft texture. The foliated 

 talc occurs segregated in bunches and small seams within the main 

 body. On the footwall side the division between the talc and the 

 wall rock is well defined but on the hanging side the talc quite 

 frequently makes off into the country rock and the offshoots when 

 followed may open up into considerable bodies. The product of 

 the mine was ground at a mill situated at Fullerville which was 

 destroyed by fire in the later part of 19 17 since which time the mine 

 has been idle. 



The Arnold mine in the southwestern section was one of the 

 properties formerly worked by the Union Talc Co. It was later 

 taken over by the International Pulp Co. and in 19 17 came under 

 the control of the Basco Corporation which recently entered the 

 district. 



The Wight and Balmat mines have been quite actively worked 

 despite their unfavorable situation which necessitates a haulage 

 of several miles to the mills which are situated along the Oswe- 

 gatchie river. The Balmat mine in fact is one of the principal 

 mines in the district. It is worked through an incline shaft which 

 starts from the surface at an angle of 27° but steepens toward the 

 bottom. The largest levels are about 1000 feet and the seam 

 measures 30 to 40 feet from wall to wall in widest part. On the
