the long and important Copper Cliff offset, passing through 

 granitoid gneiss, greenstone and greywacke. 



No. 2 mine, with its open pit 300 feet (91.4 m.) deep, 

 in a typical columnar offset deposit. 



The Copper Cliff mine itself is not now working but will 

 be visited as the richest and one of the most important of 

 the early mines. The ore body formed an irregular 

 chimney which has been followed for 1,300 feet (400 m.) 

 on an incline of 70 degrees to the east. 



After visiting Copper Cliff the party will be taken to the 

 smelter, 2-3 of a mile (1.1 km.) northeast, where officers of 

 the Canadian Copper Company will guide them through the 

 various buildings and explain the processes. The plant is 

 one of the largest and most complete in North America. 



The destruction of all vegetation in earlier years by roast 

 beds near the town has allowed rain erosion of a striking 

 kind on the old lake deposits in and near Copper Cliff. 



During the afternoon the party will return to Clara- 

 belle junction and travel 4 miles (6.4 km.) northeast on 

 the Canadian Copper Company's private railway to Frood 

 or No. 3 mine, passing most of the way through greenstones. 



At Frood the gossan-covered ridge will be ascended to 

 give an idea of the largest known nickel deposit in the world, 

 estimated to contain more than 35,000,000 tons of ore, 

 perhaps even 100,000,000 tons. It extends almost unbroken 

 for a mile to the southwest and almost as far to the 

 northeast, where the Stobie mine once produced more than 

 400,000 tons of ore. After testing it with the diamond drill 

 the. Canadian Copper Company has sunk two shafts and 

 begun work on the deposit, and the Mond Nickel Company, 

 which owns the Frood Extension, taking in a part of the 

 centre of the ridge, is sinking a third shaft. 



The Frood-Stobie offset, unlike all others, shows no 

 surface connection with the main nickel range, from which 

 it is separated by about a mile (1.6 km.) of granite hills'. 

 The deposit may be described as a parallel offset. It doubt- 

 less has underground channels connecting it with the norite 

 to the northwest, since drill holes show that the ore body 

 dips that way. 



Evening.; — Return to Sudbury, where a complimentary 

 banquet will be given by the Board of Trade for excur- 

 sion A 3.
