Gold and Silver Ores of the Slocan, B.C. 



By J. C. Gwillim, B.A.Sc. 



One of the most striking physical features of the 

 interior of British Columbia is caused by the great system 

 of lakes and rivers which almost surrounds the Selkirks 

 within their Canadian limits. 



These waterways form long north and south depressions 

 and are connected by low transverse passes, which drain 

 to the east and west. 



This region is, therefore, fairly accessible to the explorer 

 or prospector. The geology has not as yet been fully 

 worked out, but enough has been learned to show it to 

 be a region of intrusive and of uplifted rocks of undeter- 

 mined age.
