This district crosses county lines; however, the vast majority of its area is in Yavapai Co. The district is a feldspar, bismuth, mica mining area that is now idle except for systematic collection of specimens at one larger former mine. It is located about 7 miles East of Wickenburg and 8 miles North of Morristown.

The district contains a swarm of lithium-bearing and non-lithium-bearing pegmatites, some carrying bismuth mineralization, and a wide range of phosphates. There are also some non-pegmatitic mineral deposits within the district. Some of the pegmatites contain crystals of constituent minerals to many feet long.

    Habit: Very large

    Description: This material is believed to be montebrasite. Material in the core forms rough, nearly equi-dimentional masses 12 inches (30 cm) or less in diameter with rough crystal faces. Other masses are much larger. One unusually large pod, 20 feet in maximum exposed dimension appears to be an aggregate of crystals 3 inches to more than 4 feet in diameter. Chemical analyses by London and Burt (1982) supersede former field identifications of earlier publications.

    Description: London and Burt (1982) noted: "... the crandallite invariably occurs at montebrasite borders and probably was the first [secondary] mineral to crystallize. In a typical specimen (Fig. 8), a thin reaction rim of crandallite at montebrasite borders grades outward into veinlets of grayish-white hydroxylapatite, followed by an intergrowth of apatite + muscovite, and finally fine-grained green muscovite at the centers of replacement veinlets and near the crystal boundaries of the primary phase."
