Octaroon Mine, Tijeras Canyon District, Bernalillo Co., New Mexico, USAThe barite from the Octaroon mine is in thin blades while the barite from the Galena King has coarse, opaque blades that are often coated with drusy fluorite or in some case "hooded" by drusy fluorite. Barite from the Frustration mine is not noteworthy and much less common than at the Galena King or Octaroon.
Both the Galena King and the Octoroon mines are in Bernalillo Co. (as well as the Frustration mine). The Octoroon mine is about a half mile west of the Galena King and somewhat lower in elevation. The minerals at the Octaroon are virtually the same as at the Galena King (fluorite, barite, galena, quartz w/minor chalcopyrite and malachite). The barite occurs in bladed, usually white xtals and is more noteworthy than the fluorite. The fluorite is mostly in stepped octahedrons and usually a light purple to blue.
The mines were mapped in 1923 by Fayette Jones (maps held by the NM Bureau of Geology and Mineral Resources). These maps show all the adits and shafts. The mineralized veins are all almost vertical and occur in pre-Cambrian granite (gneiss).
