A NOVEL IN-TUNNEL TREATMENT REMEDY AT THE CAPTAIN JACK MILL SUPERFUND SITE
Jenkins, J. | Technical Sessions: Smart Mining: Resources for a Connected World, 24-27 Feb 2019, Denver, Colorado. p 76, 2019
A novel in-tunnel treatment remedy is operating at the Captain Jack Mill Superfund Site near Ward, Colorado. The remedy includes bulkhead with a flowthrough pipe, limestone-packed adit section, recirculation system, monitoring wells with in situ water quality monitoring, and an electroresistivity-tomography system. The concept involves flooding the mineralized zones along the adit, providing initial neutralization, recirculation, monitoring water quality changes near the adit, and determining if pre-mining conditions can be achieved. System design allows flexibility for additional amendments, if needed. Operations began in March of 2018. See more on this project in a video presented by Mary Boardman at the 2018 San Juan Mining & Reclamation Conference, Creede, Colorado: https://www.youtube.com/watch?v=bwKPSF8Sk30&list=PLXA4wMzLaGizkJ0RDi9TFs-ReuG6uXGyW&index=13&t=0s .
