A small Pb-Cu-Ag deposit that was worked in the early 1900s.

Float mineralization from the area was first found in 1888. In 1909 a regular deposit was found by Bessie and John Dunbrack. A shaft and adit were sunk but by 1915 mining operations had ceased. In 1916, Robert Ewing of New Orleans acquired the property and extended the underground workings. By June 1920 mining operations had again ceased. All that remains today at the locality is a small partially overgrown dump heap.

NOTE: The land owner does not want any trespassers going through the dumps or looking for the mine (http://www.mindat.org/mesg-105-368831.html).

Detailed Mineral List:

ⓘAnglesite
Formula:PbSO4
Habit: Tabular
