The Greenwood gold mine operated in Prince William County, Virginia, United States, near the town of Independent Hill for a few years before closing in 1885.
[1] It was one of two known gold mines in Prince William County, the other being the Crawford placer prospect on Neabsco Creek, near I-95, though small amounts of gold were occasionally found at the Cabin Branch Pyrite Mine in nearby Dumfries.
The site is situated along the Virginia Gold-Pyrite belt, which runs from northeast to southwest primarily through the counties of Fairfax, Prince William, Stafford, Spotsylvania, Buckingham, Culpeper, Cumberland, Fauquier, Floyd, Fluvanna, Goochland, Halifax, Louisa, Orange, and Patrick.
Mining operations consisted of at least one shaft, a stamp mill, and some form of mercury amalgamation recovery.
The USGS maintains two active monitoring wells [2] [3] downstream of the mine site on the South Fork of the Quantico Creek.
