Iron King Mine
The deposit has been known since at least 1886: "At Humboldt station Mr. C. S. Wright the proprietor of the Humboldt House gave me a large specimen of a magnetic ore which he told me was found in the Jackson mountains about 40 miles northwest of Humboldt where a vein of ore 15 feet wide can be traced for several thousand feet. Chippings from the specimen contained:
- Metallic Iron 66.75
- Phosphorus 0.820
- Phosphorus in 100 parts iron 0.470
"The ore is a massive magnetite free from pyrite but containing numerous long whitish crystals of apatite"
In 1959, the mine was operated by a partnership between Austin and George DeLaMare. The mine was reported to have closed in 1967.
