Notes:

The Magna Charta property that adjoins the Ironclad property has several large tanks on the ground for a cyanide plant.

That section of the Cripple Creek district embraced in parts of Ironclad and Gold hills is to undergo treatment not unlike that accorded the Black hills of South Dakota, to which it is not dissimilar.
One of the companies which will investigate its resources is the Cripple Creek & Homestake, which will commence operations about January 1.
This company expects to quarry low grade ore from open cuts and treat it by the cyanide process.

Cripple Creek, Colorado.
Homestake Mills Leased.
A five-year lease has recently been granted to the Phoenix Leasing Co. by A. W. Grant, receiver of the Cripple Creek Homestake Mining & Milling Co., on the Ironclad, Annex, and Pard claims, and the larger of the two Homestake mills.
Mining operations will be started at once. It is expected that the mill will be overhauled and put in shape for the hauling of ore by March. The royalties range from 5 to 20 %.

About 12 months ago a similar lease was granted on the Magna Charta and Quartzite claims and the smaller mill, to the Ironclad Leasing Co. This mill has a capacity of 150 tons per day and has been operated very successfully during the last year.

Mine operations have been commenced by the Lincoln Mines & Reduction Co. on the Magna Charta claims on Ironclad hill, which are owned by the Rex. M. & L. Co.
The Lincoln company is operating under bond and lease and has constructed a milling-plant on the group.

The Lincoln Mines & Reduction Co. has started underground development of the Ironclad Hill properties of the Rex M. & M. Co., held under bond and lease.
The Lincoln company's mill is on this ground and will shortly be operating. Recent tests have proved the newly developed Gasche process to be suitable for the treatment of ores from the Ironclad Hill mine.

Now that the electric-car line and Short Line steam-road have ceased operation, the Lincoln Mines & Reduction Co. provides auto transportation to and from its Ironclad Hill mine and mill without charge.
