OCCURRENCE OF TIN IN N 7 OVA SCOTIA. PIERS. 245 



ing from 75 at the surface to 60 at the bottom of the pit. 

 The outcrop is about 8 feet wide and 12 feet long, but at one 

 *end at least it extends farther to the north-east under a cap of 

 granite. The deposit, he continues, appears to be what is often 

 called by miners a i blow-out/ and is probably the result of deep 

 solfataric action, and it should extend to a great depth. He 

 considered that the results so far should be considered very 

 satisfactory and warrant much greater development. 



I had hoped that additional surface work might prove that 

 the pegmatitic cassiterite-bearing rock extended to some dis- 

 tance, as is the case in most dikes, but Dr. Young reports that 

 at the time of his visit a certain amount of stripping in the 

 immediate neighborhood had failed to disclose further outcrops 

 of the tin-bearing body, which seems to be of the nature of an 

 irregular, acid schlieren, closely connected in origin with the 

 -containing muscovite granite. He says the light-colored mus- 

 covite granite with which the cassiterite-bearing pegmatite is 

 associated, was seen at a number of points in the neighborhood 

 and appears to be cutting ai coarser-grained biotite granite.* 



Much activity followed the discovery of tin-ore at this place, 

 and several pegmatite dikes, etc., near New Boss were located 

 and prospected. The Geological Survey found traces of tin in 

 -small specimens from a pegmatite dike, 24 feet wide, a mile 

 north of Nevertell lake, six miles south of Beeves's place. Bis- 

 muthinite and molybdenite were discovered in a silicious and 

 aplitic dike or vein, one mile south of New Boss corner; and 

 tungsten ores and 1 rare earths were found in a dike of pegmatite, 

 20 feet wide, one mile east of New Boss Corner, on land taken 

 up, on a license to prospect, by Dr. Lavers and Frank Boylen 

 of New Boss.
