Groundhog Mining and Milling Co. rehabilitated two long stretches of drift that are a couple of the primary fresh air intakes for the Galena Mine. Measures taken for reinforcement were to install chain link, and resin grouted and friction bolts; as well as fresh timber sets where needed. During one of the projects Groundhog also removed and repaired failing shotcrete, as well as deteriorated mine utility plumbing.
Groundhog Mining and Milling Co. worked to reopen and access the Rescue Mine portal.

Groundhog Mining and Milling Co. worked to reopen and access the Rescue Mine portal. This included installing rock bolts with chain-link and standing steel sets through a section of surface that had collapsed in multiple places; blasting was required for some clearing purposes. Groundhog also installed rail on the surface with a railcar dumping station for rock to streamline the process and make it more efficient.
Groundhog Mining and Milling Co. removed failing portal timber sets and reconstructed a new portal using new materials. This mine was discovered in the 1800s and it follows that updates and repairs would need to be made throughout the years. Once a new portal was completed, a length of rail drift with chain-link surface support was secured, as well as additional repairs and maintenance.
