There are 447 documented abandoned gold mines in Virginia, and an estimated 500 undocumented, and they are all loaded with mercury, some with cyanide, arsenic, and other toxic materials. Many have numerous gaping and dangerous open shafts. There are some un-acknowledged superfund sites awaiting recognition. Our focus has been on stopping new industrial mining from getting started in Buckingham and Virginia. We would also like to see the existing mess cleaned up. This article includes:

Virginia’s Former Gold Mines with Priority Level for Reclamation – PEC WebMap
In 2022, The Piedmont Environmental Council was proud to partner with student volunteers from UVA’s Clark Scholars program on a project to analyze the status of former gold mine sites throughout the Commonwealth. Using data pulled from the Virginia Department of Energy’, including its Mineral Mining online mapping interface, the students’ research enabled PEC to produce the new WebMap embedded below. Our interactive map shows the location of former gold mine sites in Virginia, and importantly, visually displays each mine site’s “OLAC ranking,” a measure of prioritization for reclamation based on site assessments and potential contamination (red corresponds to the highest priority for cleanup).

Wilderness Crossing Development in Orange County
Article dated March 14, 2023; Even after 18 months, it is still unclear what the applicant has planned for the 2,618 acres of land included in the Wilderness Crossing rezoning proposal — still un-remediated of toxic hazards from historic gold mining activities. The details have continued to change, and most recently, the number of homes has been reduced from 6,500 to 5,000 while the industrial square footage has increased by almost five times. Additionally, a variety of industrial uses, including data centers and warehouse/distribution centers, would now be allowed by-right.
An article dated October 25, 2022: In addition to concerns about taxes, infrastructure (water and sewer), traffic, and habitat fragmentation, Wilderness Crossing is also the site of numerous unreclaimed gold mines—essentially, mines that have never been closed off and cleaned up of contaminants such as mercury, arsenic, cadmium and lead. The largest mine on the property, called the Vaucluse mine, has been documented by state inspectors as the site of extreme mercury contamination. Since it was never cleaned up, the tailings pit is likely still leaching toxic chemicals into Shotgun Hill Branch today and is an expected source of contamination in Wilderness Run, and ultimately, the Rapidan and Rappahannock rivers. PEC recommends that Orange County seriously consider how the toxic legacy of gold mining at this location could impact the health, safety and welfare of future residents and downstream communities.
Re-mining and reclaiming abandoned gold mines
& local zoning prohibitions on new gold mining
Cleaning up existing toxic contaminations from the many abandoned gold mines in Virginia needs to be well understood, and for actions to be taken. Care must be taken in making new laws and regulations for new metallic mining, to allow for and promote re-mining and reclamation in an effective and safe way.

THE NEW DIGITAL SURFICIAL GEOLOGIC MAP OF VIRGINIA:
A COMPLEMENT TO THE 2021 GEMS LEVEL-2 BEDROCK
GEOLOGIC MAP OF VIRGINIA

In 2021, Virginia Energy (serving as Virginia’s Geological Survey) delivered to the USGS National Cooperative Geologic Mapping Program updated statewide digital geologic maps for the Commonwealth. Previously, statewide geologic maps were produced at 1:500,000-scale in 1916, 1928, 1963, and 1993. This 2021 “born-digital” map product was completed using the USGS Geologic Map Schema (GeMS) geodatabase format and compiled at a nominal scale of 1:250,000.
In addition to bedrock contacts and map unit polygons, Virginia Energy also delivered derivative surficial map unit polygons. This is the first time that a comprehensive surficial geologic map was attempted at the statewide scale. Surficial units were identified using published geologic maps and interpreted using a compiled 10-meter resolution statewide LIDAR DEM assembled from 24 separate 1-to-5-meter LIDAR datasets generated between 2010 and 2019. Surficial units were digitized on-screen as part of the MapUnitOverlayPolys feature class at 1:24,000-scale. Over 7600 surficial features were digitized including alluvium, colluvium, fan deposits, river terraces, artificial fill, and Carolina Bays.
Significant effort was made to update coastlines along the Chesapeake Bay and inland rivers. These boundaries served as contacts for both the surficial units and bedrock units, and contributed to database topology. In the Coastal Plain Province, east of the Fall Zone, some surficial deposits also serve as map units on the bedrock geologic map (e.g. Miocene/Pliocene-aged terrace deposits). Whenever possible, surficial Coastal Plain units were migrated from geologic map unit polygons to surficial map units, exposing older bedrock units underneath in the final iteration of the bedrock polygons. Along with the statewide geologic map, the surficial geologic map is currently in review. Virginia Energy will publish these finalized datasets as part of our digital web map services in 2023.
