Early History
From the Mining Journal of Arizona – “David L. Roscoe of Tombstone holds a lease and option to purchase of the Walnut and the Bluebird 2, 3, and 4 claims located near Tonto Basin. Development of the Walnut claim consists of a 14 ft. shaft and a 5 ft. test pit. Mrs. Rhoda A. Packard, Mrs. Nora J. Cline and C. H. Pettengill, all of Tonto Basin, are the owners of the property.”

Glen Walker went to the fluorspar operation of Tonto Basin Mining & Milling Company at Punkin Center. He had the following to report: “The second ball mill was placed in operation June 12. It has increased the capacity to 125 tpd. Their Blue Bird mine about 5 miles E. of mill is developed on two levels approximately 100′ apart by adit drifts. In the lower adit there are 9 chutes, the first about 300′ from the portal. They are approximately 30′ apart. Beyond the last chute it is about 105′ to the face, which is barricaded off. Although the stopes were not visited, the foreman, Mr . William McKenzie said they are about 300′ long and broken thru to the surface for a length of about 25′. The trend of this adit varies from N 65W to N 85W. The vein dips steeply north and is 3-6 feet wide in red medium grained granite.”
“The upper adit trends S75 degrees -80 degrees W for about 150′ then turns to about N80W. Here there are 2 raise & chutes about 100′ apart; the first being 130′ from the portal. Present work is stoping between the two levels as most of the minable ore above the upper level has been removed. The equipment consists of a 250 cfm Le Roi portable compressor. Two 14 cu. ft. 18″ gauge end dump cars, a l2B Eimco mucker, with an undetermined number of jack-legs and stopers, tungsten insert, solid 7/8″ shank steel is used throughout. A Bobcat mucker and a 5 HP air slusher were outside the lower portal. At the upper adit is a 250 cfm G-D portable compressor.”
“The company is trying to get 22 degree inclined shaft sunk in a steep, narrow canyon 300 to 400 feet NW of the lower adit. It is 212 feet deep and they are wanting to contract the balance of it. No drill holes were put down therefore, the remaining depth is unknown.”
“As stated above,the mineralization occurs along a fault in red granite which can be traced at least 1500 feet. From 400-1000 feet east of the lower portal, the fault is in a wash from which about 1000 tons of spar has been mined.”
