A report from the Arizona Bureau of Geology and Mineral Technology describes the mine thusly:
<blockquote>

The Jack White mine is in the northern foothills of the Phoenix Mountains, about 18 miles by road from the railway at Phoenix.


This deposit was located during the eighties. In [[1913]], J. White and associates organized the Eyrich Gold Mining Company which sank the shaft to a depth of 300 feet and ran some drifts. C.K. Barnes erected a 10-stamp mill on the property in [[1928]] and produced several thousand dollars' worth of bullion. In [[1931]], the Hartman Gold Mining and Milling Company sank the shaft to the 500-foot level, did considerable drifting, and shipped several car loads of ore that contained from $12 to $16 worth of gold per ton. A new mill, equipped for floatation and concentration, was built in [[1932]], but operations were suspected in October, 1933. When visited in May, 1934, the mine was being worked on a small scale by Mr. White.


The principal rocks in this vicinty are dark-gray granite with small included masses of schist and a few dikes of acid porphyry.


The vein, which is traceable for a few hundred feet on the surface, strikes southwestward at its northern end, southward at its southern end, and dips about 60° W. It has been opened by a 500-foot inclined shaft and about 3,000 feet of drifts. An ore shoot seen on the 200-foot level is about 35 feet long by a maximum of 2½ feet wide but lenses out abruptly. The ore consists of coarse-textured, locally vuggy, grayish-white quartz with some calcite and irregular bunches of hematite. In a few places, unoxidized masses of finely granular pyrite are present. The gold is finely divided and has formed no placer deposits.


According to Mr. White, one stope between the fourth and fifth levels is about 50 feet long at the top by 100 feet long at the bottom and averages about 2 feet in width. He states that the three ore shoots exposed underground pitch steeply sourthward.
