2.13.06. Example 45d Gold elsewhere in Canada. At the 

 headwaters of the Chaudiere River, in eastern Quebec, auriferous 

 gravels have been located, and also quartz veins in the metamor- 

 phic rocks. They have been worked to a small extent. Gold oc- 

 curs in many places north and west of Lake Superior in the region 

 of the Lake of the Woods. Some small mining has been carried 

 on. An interesting and important vein, carrying auriferous mis- 

 pickel in quartz, occurs in Marmora, Hastings County, just north 

 of Lake Ontario. It is more fully described under " Arsenic," 

 as it is the one American source of that metal. Auriferous gravels 

 occur in British Columbia in not a few places and are being 

 worked. They are also found along the disputed boundary of 

 Alaska, and scattered reports of their existence have reached civ- 

 ilization from the Mackenzie River and the remote Northwest. 1
