Starting in 1867, iron-rich [[gossans]] were mined for precious metals in Lane Valley west of Ely. The Aultman and Saxton Mines were operating by the 1870s. The Chainman Mine was developed by the 1890s and became the most productive in the area. Starting in 1903, copper was mined by the Giroux Consolidated Mining Company and by the Nevada Consolidated Copper Company in 1904. In 1913, Consolidated Copper Mines Company took over Giroux.
 
In 1936, Fulton and Smith first described [[magnesite]], yet by 1942, when deposits were first studied no magnesite mining existed.<ref>{{cite web|url=https://pubs.usgs.gov/bul/0978a/report.pdf |archive-url=https://web.archive.org/web/20170215212721/https://pubs.usgs.gov/bul/0978a/report.pdf |archive-date=2017-02-15 |url-status=live|last=Vitaliano|first=Charles J.|title=Magnesium-Mineral Resources of the Currant Creek District, Nevada|work=Contributions to Economic Geology, 1951 Geological Survey Bulletin 978-A|publisher=United States Government Printing Office|year=1951|access-date=August 21, 2022}}</ref>
