Employees from Thyssen Mining complete construction of a temporary work platform over the main ore pass on the 4850 level. All blasted rock from the project will be dumped down this pass before being hoisted to surface.

From the Black Hills Pioneer, Aug. 21, 2021: The former Homestake Gold Mine in Lead, SD was dedicated as the M. Michael Rounds Operations Center at the Sanford Underground Research Facility. The dedication event included remarks from many dignitaries including Sanford Lab Executive Director Mike Headley, who talked about the long journey it has been to support the new facility and that Sanford Lab has made great strides toward building the LBNF that will house the Deep Underground Neutrino Experiment at 4,850 level, led by Fermilab.
How do you build a ship in a bottle? Everything necessary to construct the enormous Fermilab-hosted international Deep Underground Neutrino Experiment must fit down a narrow, mile-deep shaft cut through solid rock. Contractors have started the months-long process of disassembling excavation equipment and lowering it underground.
