Locality type:


Location & History: The Menifee or Auld district is in western Riverside County about eight miles S of Perris. The area was first mined many years ago, and there has been minor prospecting since.

Mineralogy & Geology: A number of narrow quartz veins contain free gold and in places abundant pyrite. The country rock is quartz diorite.

Mines: The principal gold sources have been the Menifee, Lucky Boy, and Mammoth mines, none of which has been extensively developed.
