NO. 2 BIBLIOGRAPHY OF TIN HESS : 51 



CANADA (Continued) 



Tin has been shown to occur to the extent of 0.17 per cent in zinc ore from the 

 Payne mill, near Sandon, Slocan district, B. C., and traces of tin are reported in 

 lead at the Trail smelter, the ore of which is supposed to have come from the 

 Slocan district.

A very small quantity of cassiterite was found in graphitic gneiss derived from 

 limestone, at Graphite City in the Ottawa Valley, Canada. 



Proved by this test: "It was dissolved in a borax bead colored slightly blue 

 by copper monoxide; the bead assumed a ruby color or became opaque, resembling 

 red sealing wax." Occurs with rutile, augite, quartz, titanite, pyrite.

Mg. World, Vol. 25, 1906, Chicago, p. 213. 



Large extent of alluvial ground; estimated that there is in sight ten million dol- 

 lars worth of ore. Even the overburden is highly payable. Abundance of water. 

 Country rock mainly granite mostly of fine structure, in places passing into 

 syenite, belonging to the Cape system. Hills are traversed in a north and south 

 direction by bands of greisen, with closely associated quartz lodes dipping to the 

 east.

 are being worked.
