Near Hibbing in St. Louis County, Minnesota — The American Midwest (Upper Plains)
Oliver Mining Co. Headquarters / Oliver Shop Laboratory
This building was the heart of the Oliver operation, the largest iron ore mining operation in United States history. The Superintendent of Mines and his staff made the day-to-day mining decisions here, and they were supported by a staff that handled clerical work, payroll, record keeping, hiring and firing, and other administrative functions.
Oliver Shop Laboratory
When the ore was mined, samples were crushed into fined particles and brought to this building. Chemists examined the ore, and determined its iron content from which the price of the ore was calculated and also how it would be processed to make steel. The samples were then put in containers and cataloged according to where the ore was mined and the percentage of iron. The containers were then stored in sample houses behind the laboratory.

1. Oliver Mining C°
I just discovered one of my ancestors was a miner at Oliver Mining Company.
Edward Aloys Hofkens emigrated from Nieuwkerken, East Flanders, Belgium to Dickinson, Norway, MI in 1913 to the U.S.A.
It is interesting to read something about the mining where he worked, this is our opportunity to learn more from our ancestors who emigrated to the States.
Thanks for the information!
