CIM Bulletin, 1937

THE prospector and geologist in the field, in the search for gold, are very often faced with a real difficulty. The: mineralized rock _frequently contains gold which is so finely divided or associated with sulphides that it is not recognizable in the gold pan. In recent years, the practice has been to take samples, send them to an assay office, and sit down and wait for results. This paper describes a method of solving the difficulty of proving the presence of this fine gold.
