On April 2, USGS research scientists Douglas Yager, Brian Rodriguez, and Maria Deszcz-Pan hosted a successful and well-received Open House in Silverton, CO. The Open House purpose was to discuss a new state-of-the-art airborne time domain electromagnetic survey covering part of the designated Bonita Peak Mining District Superfund area. This survey is part of a Mineral Resources Program project, co-led by Yager and Eric Anderson, “A Shallow- to Deep- View Inside the Hydrothermally-Altered and Mineralized Silverton Caldera Complex: New Geologic Insights Gained From Modern Geophysical Interpretations”.

At the Open House Yager, Rodriguez, and Deszcz-Pan presented a project overview, and along with the geophysical contracting company representatives (Geotech), answered questions about the new electromagnetic geophysical survey, that was designed to image subsurface lithology, hydrothermally altered rocks and mineral deposits, and possible groundwater flow paths along faults and in surficial deposits. The Open House was attended by over 30 lead scientists from the USGS, BLM, U.S. Forest Service, Colorado Division of Reclamation, Mining and Safety, Colorado Department of Public Health and Environment, Animas River Stakeholders Group, Mountain Studies Institute, national and state congressional staff, City of Silverton local representatives, and members of the local press.
