This workings represent the consolidation of several earlier workings on the same deposit (Wheatley lode). It was a lead-silver mine. The mine was started in 1851 and closed in the 1860's. It was reopened in 1917 and closed in 1920. The larger enterprise was owned by Mr. Charles Moore Wheatley. Subsequently, when reopened, it was owned by Eastern Mining & Milling Co. The mine consisted of 5 levels with 2,108 meters of horizontal workings, 6 shafts (main engine shaft = 91 meters deep). Rock is adamellite, a granitic intrusive rock of Precambrian age (Mineralization, Triassic period or earlier). Mines include the Wheatley, Brookdale and Phoenix mines.

Note: sadly, many mineral specimens collected from this district, and especially those collected in the 19th century during the mines operation, have locality attributions listed as simply "Phoenixville". Although the Wheatley mine was the most prolific of these mines, and likely produced the majority of specimens now in collections (Charles Wheatley himself was an great mineral enthusiast, with a cabinet of over 6000 specimens from his mines), other mine sites, especially the Chester County Mine, were also quite prolific, and many specimens labled without specific mine site attibutions have since been inappropriately attributed to the more famous Wheatley mine. As such, most "Wheatley" specimens should be considered "district" specimens, unless otherwise noted as "definitively" emanating from the either the Wheatley mine or it's old dump site.

Coordinates given are for the sight of the Brookdale mine and dumps. Other mine coordinates are as follows:
South West Chester Mine: 40°06'15"N, 75°31'16"W.

Large quantites of the Pyromorphite had been smelted durring the opperaton of the Mines.

Wulfenite
Formula: Pb(MoO4)
Habit: vary widely from square platy tablets to elongated steeply pyamidal
Colour: vary widely from bright yellow, reddish orange to greyish
Fluorescence: none
Description: The Phoenixville mining district is the only Pennsylvania locale where Wulfenite is found in any abundance, yet even here, the crystals are small and widely scattered. Wheatley Wulfenite varies widely in both form and color, even within an area as small as a single specimen. The mineral Stolzite was incorrectly identified here, in part due to Wulfenites variety of habit in such close association. Wheatley himself made this error in identification (Genth; Min PA 1875, pg.145) as did Samual Gordon (Min PA 1922, pg.148). Not until 1965 was a specimen of suposed Stolzite x-ray powder tested and proven to be simply grayish, pyramidal crystals of Wulfenite.
