Table showing Results of Cyanide Treatment of Concentrates.

Note.—lt is but fair to add that the Company's books were examined by me, and that the results here shown are taken from them. The ore is carefully assayed every day, and the result entered in a book kept for the purpose in above form, which shows that a fair percentage of the precious metals are obtained. It will be seen that the richer the concentrates the higher percentage of gold and silver are saved.
