Upton mine, Upton, lot 61, range 20, has yielded 

 14 per cent, copper. The quantity of rock ex- 

 cavated is not stated. Bissonet mine, Upton, 

 lot 49, range 20, exhibits a bed of 3} feet 



thick, and the ore lies in disseminated masses 

 of variou-- .-izis up to 20 inches long by 6 to 9 

 inches thick. It is estimated that the bed would 

 yield from half to three-fourths of a ton of 10 

 per cent, ore to a fathom. In the "Wickham 

 mine, Wickham, lot 15, range 10, an experi- 

 mental shaft has recently been sank to a depth 

 of about five fathoms, in which good bunches 

 of ore have been met with. About 4,000 tons 

 have been taken out, yielding 30 per cent. The 

 Yales mine, Durham, lot 21, range 7, has been 

 opened to a depth of from two to six fathoms, 

 revealing good lumps of ore, mixed with 

 calcspar and wall rock. At St. Flaviere, about 

 five leagues above the Chaudiere, and two 

 leagues from the St. Lawrence, is the Black 

 River mine. In one spot native copper occurs 

 in small masses; and the whole bond has a 

 striking resemblance to the upper copner- 

 bearing series of Lake Superior. At Harvey's 

 Hill mines, Leeds, lot 18, range 15, there oc- 

 curs in a breadth of about 1,000 feet eight 

 courses, composed chiefly of quartz, with va- 

 rious proportions of bitter spar, chlorite, and 

 calcspar, carrying in parts as much as two tons 

 of 20 per cent, ore to a fathom. The rock of 

 the country is a talcoid mica slate. An adit 

 level is being driven through this slate, of tho 

 length, when completed, of 220 fathoms. The 

 number of men employed is about 50 ; but the 

 quantity of ore taken out is not given. At the 

 St. Francis mine, Cleveland, lot 25, range 12, 

 tho bed has an average thickness of three feet, 

 and has been traced a distance of 90 fathoms. 

 The monthly yield of ore is about 55 tons of 10 

 per cent. The Huntington mines at Bolton 

 yield about 10 tons of 10 per cent, ore per 

 fathom. The ores of all these mines are the 

 yellow, variegated, and vitreous sulphurets, 

 mixed in some instances with copper pyrites. 



Gold Minea of Canada. In Canada, the 

 gold-mining operations have been principally 

 carried on in tho Chaudiero division, in alluvial 

 diggings on the Gilbert River, in tho Seigniory 

 of Rigaud Vaudreuil (De Lory). About fifty 

 men were working there at tho date of the last 

 report (June, 1866). One or two companies 

 are about erecting mills for quartz-crushing. 

 The gold hitherto extracted is estimated as 

 follows : 



In summer of 18C3 $50,000 



In June, 1864 5,000 



Year ending June, 1865 150,000 



" " " 1800 100,000 



The probable falling off in 1866 is explained 

 by tho prevailing excitement with regard to 

 quartz crushing, which caused an abandon- 

 ment of alluvial operations. The largest 

 nuggets found in tho Chaudidre valley have 

 been worth $300, and most of the alluvial gold 

 has been obtained in a limited area. In that 

 district, and also in other parts of Canada East, 



gold-bearing quartz veins have been discovered 

 of sufficient richness to pay a handsome profit 

 on tho cost of crushing and separating. 



Gold-Mines of Nova Scotia. The productive- 

 ness of these mines appears to be permanent. 

 They are worked under tho direction <.f the 

 Commissioner of Mines, and the Government 

 reserves a royalty of three per cent, on the gross 

 receipts. The following is the commis:-ioner'n 

 report of the number of hands employed in tho 

 gold-mines, the tons of quartz raised and crushed, 

 nnd the daily yield of gold per man employed, 

 from 1862 to 1865 inclusive :

It also appears from the commissioner's re- 

 port that the aggregate amount of gold upon 

 which royalty was paid in 1865 exceeded that of 

 the preceding year by about 33 per cent., 

 amounting to 24,687 ozs. for the former period, 

 and 18,744 ozs. for tho latter, showing an in- 

 crease of 6,123 ozs. There is al?o an increase
