Dec. 7, 1912

Ninety dollar ore was found in the Ostrich mine in the Oro Blanco District Thursday. (The area is south of Arivaca.) The ledge is three and one half feet wide. The ore is a white iron sulphide, and according to the statement of Todd C. Woodworth, the men worked in the ore for 10 days before discovering that it ran high in gold values.

The dyke is a separate one from that which the Austerlitz mine is located on, and the fault plane is separate. The Austerlitz mine is three miles distant from the Ostrich. The latter mine is being worked by Billy Lane and Todd C. Woodworth.

Three shafts are sunk on the ledge at the Ostrich. One of them is 100 feet deep, the second 30 feet, and the third is 60 feet. Drifts connect these three shafts. The property is an old one and was owned formerly by Hank Bartlett. It was stated by Woodworth that the mines were procured from the son of Bartlett about three months ago.

Nothing toward taking out the ore will be done for a time at least. It will be blocked out in order to determine the extent of the new find. Men are working on this part of the operation now. Woodworth stated that he thought a new find would prove to be an excellent one. He was unable to state the probable amount of ore that is included in it.
