In October 2024, DA Smith successfully completed a two-year surface drilling campaign for the U.S. Environmental Protection Agency at the Bonita Peak Mining District Superfund Site near Silverton, Colorado. Multiple angled and vertical holes were cored using directional steering to depths reaching 900 feet, targeting underground workings of the historic Sunnyside gold mine. Holes were completed as 3-inch or 4-inch water monitoring wells for ongoing hydrologic study. At the start of each drilling season, mobilization to the high-alpine mountain site, located at an elevation of 12,200 feet, required clearing deep snow and tramming heavy equipment with a dozer.
