Mineral King is in central Tulare County in the high Sierra Nevada, about 37 miles east of Lemon Cove near Sequoia National Park. It is a small mining district that has yielded minor amounts of gold, silver, copper, lead, and zinc. Gold- and silver-bearing are was discovered here in August 1873, and a "rush" to the area was on during the following year or two. However, little mining has been done in the district since, and it is now a well-known resort area. The Mineral King deposits occur in a belt of contact metamorphism in calcareous slate, impure limestone, and granodiorite. The are is complex and consists of quartz and epidote rock containing pyrite, chalcopyrite, -sphalerite, galena, arsenopyrite and, in places, gold and silver.
