 Second Day. 



7 a.m. — Leave Sudbury by Algoma Eastern railway for 

 Creighton, passing for 2 miles (3.2 km.) through grey- 

 wacke, followed for a mile (1.6 km.) by arkose and then 

 by greenstone. At 3% miles (5.6 km.) west a branch runs 

 south to Copper Cliff. Beyond this greenstone and granite 

 extend to the norite of the Copper Cliff offset, here about a 

 mile (1.6 km.) wide. For the rest of the journey the rail- 

 way runs southwest near the contact of the norite with 

 coarse granitoid gneiss. 



Creighton, alt. 973 feet (296.5 m.) is 11 miles ( 17.7 km.) 

 by rail west of Sudbury. The party will walk south through 

 the village to a hilltop of granite and gneiss from which 

 there is a broad outlook over the gossan edge of the nickel 

 range and the mine with its surroundings. The hill displays 

 interesting crush conglomerates as well as small faults 

 caused by the arrival of the nickel eruptive. A walk will 

 then be made past the east end of the mine to a character- 

 istic contact of norite with the older gneiss ; after which the 

 gossan hill and the great open pit, 300 feet (91.4 m.) deep, 

 will be visited. Those who wish may descend 60 feet 

 (18.3 m.) to the first level of the mine, following the foot 

 wall of the ore body. 



Specimens of pyrrhotite, chalcopyrite and probably 

 pentlandite may be obtained, as well as of pyrrhotite- 

 norite, ordinary norite, and diabase, the latter cutting the 

 ore. 



10 a.m. — Return by the A.C.R. to Clarabelle junction, 

 where the Canadian Copper Company's line will be taken 

 south for 2 miles (3.2 km.) to Copper Cliff. 



The line passes through the great roastyard where heaps 

 of ore from the Creighton and other mines may be seen at 

 every stage, some in process of building, others steaming 

 with sulphur fumes, and others forming rusty heaps of well 

 roasted ore. 



Beyond this is the rockhouse of No. 2 mine, and then 

 the large buildings and stacks of the smelter, followed by 

 the town of Copper Cliff with its polyglot population of 

 2,500, mainly from Finland and southeastern Europe. 



A walk will be taken to Lady Macdonald lake, 

 where the edge of the norite narrows to a funnel leading to
