Gilta is in the southwestern comer of Siskiyou County near the head of Knownothing Creek and about five miles south of Forks of Salmon. Most of the gold output here has come from the Gilta or Gold Hill mine, which has a reported production of $1 million, and from the extremely rich placers of nearby Knownothing Creek. The Gilta mine was worked on a large scale, mostly prior to 1900. The gold-quartz veins occur in slate and schist and are associated with diorite dikes. One ore shoot at this mine was 250 feet long.
