From The Black Hills Pioneer, July 2, 2021: As excavation begins for the LBNF/DUNE, planning and communication are critical to lowering huge pieces of equipment underground. Read more about how Thyssen Mining and the Sanford Underground Research Facility crews are working together to ensure everyone understands the plan and the process.

The Ross Hoists, built in the 1930s, receive major upgrades in preparation for LBNF/DUNE construction and operation.
From Construction and Engineering, March 16, 2021: A construction and engineering short view on the development of DUNE and the impressive engineering and excavation process involving hundreds of thousands of tons of rock almost a mile below the surface.
From Público, Nov. 24, 2020: Homestake fue la mayor y más profunda mina de oro de de Norteamérica hasta que se cerró en 2002 tras 125 años de funcionamiento. Este remoto lugar de Dakota del Sur se convirtió oficialmente en 2007 en un laboratorio subterráneo de física fundamental, aunque ya mucho antes se habían instalado en sus profundas cavernas algunos experimentos, incluido uno que mereció el premio Nobel. Ahora se anuncia la nueva etapa para convertir la mina en sede del megaproyecto científico más importante de las últimas décadas en Estados Unidos, el Long-Baseline Neutrino Facility, dedicado a estudiar las partículas fundamentales llamadas neutrinos.
From Sanford Underground Research Facility, Nov. 24, 2020: Another series of upgrades to the Ross Shaft is underway at the Sanford Underground Research Facility. Crews are working to outfit the shaft with new cage and skip conveyances and have replaced thousands of feet of hoist cables. The work prepares the Ross Shaft for its role as the main travel way for upcoming excavation and construction of the Long-Baseline Neutrino Facility to support the Deep Underground Neutrino Experiment, the world’s flagship neutrino experiment, which is hosted by Fermilab.
From Black Hills Pioneer, Nov. 17, 2020: Thyssen Mining Company, one of North America’s largest mining companies, has signed a three-year contract to excavate space for the Long Baseline Neutrino Facility at Sanford Lab in South Dakota. The company plans to bring about 110 jobs for miners, operators, mechanics, electricians, engineers, and managers. Thyssen Mining is currently preparing office space in Lead, as well as getting personnel lined up, contracting with local vendors, and preparing equipment for the project.
Department of Energy officials have formally signed off on project completion for LUX-ZEPLIN, or LZ: an ultrasensitive experiment that will use 10 metric tons of liquid xenon to hunt for signals of interactions with theorized dark matter particles called WIMPs.
From Rapid City Journal, Aug. 6, 2020: Crews have begun installing a rock conveyor over U.S. Highway 85 in Lead, South Dakota, for the Long-Baseline Neutrino Facility. The conveyor will bring 800,000 tons of rock from the 4850 level of Sanford Underground Research Facility and deposit them into an open pit mining area that was excavated by the Homestake Gold Mine in the 1980s, making way for the international Deep Underground Neutrino Experiment, hosted by Fermilab.
From Sanford Underground Research Facility, Aug. 4, 2020: The most publicly visible milestone of the Long-Baseline Neutrino Facility’s pre-excavation work, a conveyor system, now extends over U.S. Highway 85 in Lead, South Dakota. Installation of the conveyor is one of a series of infrastructure strengthening projects undertaken to prepare the Sanford Underground Research Facility for its role as LBNF’s far site. Such projects lay the groundwork for the Deep Underground Neutrino Experiment, the most ambitious particle physics experiment on U.S. soil, hosted by Fermilab.
From Black Hills Pioneer, July 22, 2020: Since late 2019, work has been underway on the Long-Baseline Neutrino Facility conveyor system at the Sanford Underground Research Facility in South Dakota. The system will carry more than 800,000 tons of rock excavated from the site of the international, Fermilab-hosted Deep Underground Neutrino Experiment 4,850-feet below the surface. A major milestone for the project was met on July 20 as the 120-foot section of the truss, which will house the conveyor, was erected above the highway.
