At a banquet to celebrate the completion of the second unit of cyanide plant for the treatment of low grade dump ore at Stratton's Independence, Cripple Creek, Philip Argall gave a speech containing interesting reminiscences.
Eighteen years ago he commenced his connection with the cyanide process by going to Deadwood, South Dakota, in the interests of the owners of the MacArthur-Forrest patents. At this spot in the Black Hills a cyanide plant had been erected and had proved a failure at first, and advice was required.
His second trip was to what is now the Brodie mill at Cripple Creek, where the cyanide process was also a failure. In both these cases the ore was ground fine and could not be leached; this was in the days before slime agitators.
Nevertheless Mr. Argall was firmly convinced that cyanide treatment would be the most suitable for Cripple Creek ores, and by tongue and pen was persistent in his advocacy of its adoption. Indeed he then made a design for a treatment plant which was adopted 14 years later at Stratton's Independence.

During 1902 the Brodie Reduction Plant in the Cripple Creek District handled 250 tons of ore at a value of $ 2,000.

During the month of March, the Brodie mill were an important factor for the district's increase in mill-grade production. The increase in the mill-grade production is very gratifying. It is due to the increased capacity of the reduction plants treating Cripple Creek ores.

During February the Brodie mill outputted 600 tons with average value of $30.00 for a total of $18,000.

BRODIE MILL WILL OPEN
—————————
Mound City Concern Will Start Up Again.
—————————
CAPACITY IS SIXTY TONS
—————————
WILL AFFORD ANOTHER OUTLET FOR THE ORE OF THE GREAT GOLD CAMP.
—————————
It was reliably reported last evening that, within a week, the old Brodie mill will be reopened, under entirely new management. Whether the mill will be leased or not, could not be learned, but no matter under what conditions the mill opens, there will be another outlet for the already congested condition of the ore market.
The Brodie mill has a capacity of 60 tons a day, and when it opens there will be no difficulty in filling it with ore, and the mill can run full blast without losing an hour.
The mill was one of the first in the district, and that it was closed, even temporarily, was surprising to all, and the news that it will again open will be hailed with delight by people who, at present, have no outlet for their ore.

The July output of gold ore, in spite of the fact that the month claimed a long holiday, the return from the Brodie Mill show same high standard as set in June. The mill treated 1,840 tons with average value of $29.00 to a total of $53,360.00.

The Brodie cyanide mill in Mound City treated during June fully 1,850 tons for a total of $51,800.

The April's output of gold from Cripple Creek has been computed and the figures at hand show increase rather than diminution of the steady stream of wealth flowing from the mines. During this month the Brodie outputted 2,500 tons.

John Q. MacDonald of the Brodie mill left for Denver last night. He will return Thursday.

At Mound City we see a large cyanide mill which appears to be successfully solving the problem of the treatment of the Cripple Creek ores by the cyanide process, a process which may be roughly described thus : The rock and ore are ground very fine and then pass into vats containing cyanide of potassium, the acid of which dissolves both quartz and ore. Zinc filings or shavings are then thrown in and the gold precipitates on the filings and is cleaned off and saved.
