· —Many of the ores we run would come under the head of " rich spotty " ores, as the Colorado phrase is. To crush and cut down such an ore, according to best Colorado rules of sampling, would require breaking the whole batch of from 500 to 1,000 lb. down to 10 or even 30mesh. This would ruin our gold stampmill run.
