After all, the lead and zinc mining industry was a dominant industry for decades in the region, and notable advancements in mining were made in the area. The most obvious reason is because the Missouri School of Mines was founded in 1870. Joplin, founded in 1871, was not yet a muddy mining camp on the edge of Ozarks.
In the background, two miners examine the roof of the mine. From the beginning, lead and zinc mining in the Joplin district was a dangerous means to make a living, and if lucky, a fortune, too. The year 1910 was considered a good one, respectively, when compared to 1909 when 51 miners lost their lives.

6 Lead and Zinc. Lead and zinc ores are usually found together with gold and silver. A lead-zinc ore may also contain lead sulfide, zinc sulfide, iron sulfide, iron carbonate, and quartz. When zinc and lead sulfides are present in profitable amounts they are regarded as ore minerals. The remaining rock and minerals are called gangue.
