96 MINERAL RESOUKCES. 



mineral has also been found in profitable quantity on Onslow Moun- 

 tain, in Colchester County. It is associated with limonite on the 

 East River of Pictou, and its occurrence has been reported in several 

 other places, though in uncertain quantity. 



Lead. — A vein of galena has been worked on in Caledonia, 

 Guysboro', though as yet the results are uncertain. A vein of 

 argentiferous galena, yielding 135 lbs. lead and 2'95 ounces of silver 

 to the ton, is also reported on the North River of St Ann's Bay, Cape 

 Breton. This vein is stated to be five inches in thickness. The 

 deposit of galena in Lower Carboniferous limestone at Gay's River 

 (Ac. Geol., 275) has also attracted some attention, but I believe has 

 not been worked on a large scale as yet. 



Antimony. — Stibnite, or antimony glance, occurs in veins in a 

 gangue of quartz, in rocks believed to be of Upper Silurian age, at 

 Prince William, York County, New Brunswick. The ore is mined 

 and smelted with profit, and is also made into the alloy named 

 " Babbit Metal." 



Gold. — In Nova Scotia thirteen gold districts are reported as 

 being worked in 1876. The total yield was 12,038 ounces, nearly 

 half of this being from the Sherbrooke district, and the next most 

 important being those of Oldham, Waverley, and Wine Harbour. 

 All the gold mines at present worked are in tlie Cambrian Quartzitc 

 formation of the Atlantic coast, with one remarkable exception. This 

 is the Carboniferous conglomerate of Gay's River, referred to in 

 Acadian Geology (p. 277) as an instance of a gold alluvium of 

 Lower Carboniferous age, and as a proof that the gold veins are of 

 older date than the Carboniferous. It is stated in the report of the 

 inspector that in one area the conglomerate was worked along a run 

 or depression of the slates for 500 feet. 



The gold is obtained by breaking up the conglomerate and 

 panning the debris ; and, as in most modern gold gravels, the 

 richest part of the deposit seems to be near the bed rock. 246 

 ounces were obtained from this deposit in 1876. Professor IJind 

 states* that a similar instance of the occurrence of gold in a Car- 

 boniferous conglomerate occurs in the peninsula opposite Baddock in 

 Cape Breton. Here, however, it is near the summit of a thick con- 

 glomerate, implying peculiar circumstances in its deposition. 



The gold-mining industry is believed at present to be in a healthy 

 state, though reduced in amount from the times of early excitement ; 

 and it is likely gradually to extend. 



Silver. — The sulphide of this metal, and also argentiferous galena,
