A former Li-Ta-Nb-feldspar-mica mine. The North Morning Star mine is located about 600 feet N.10ºE. of the South prospects in the W.½ sec. 16, T.7N., R.3W., on the NW side of San Domingo Wash.
Mineralization is the North Morning Star pegmatite that dips irregularly, steeply and trends NNE to NE along the same prominent ridge.
The pegmatite body is about 50 feet in outcrop breadth (main cut area), and broadens NE-ward to a maximum of nearly 100 feet. Prominent branches extend eastward and NW-ward. The pegmatite is remarkably well-zoned (see Jahns (1952) for details).
The country rock is thinly foliated, light to medium gray quartz-biotite-muscovite schist. Its well-developed planar structure trends WNW and dips NNE at moderate to steep angles. The rock is cut by several dikes of fine-grained, dark gray amphibolite, and also contains numerous quartz veins. The pegmatite-wallrock contacts are sharp, and in places the outer part of the pegmatite body is complicated by tabular inclusions of elongate septa of schist.
Workings include the main cut, a large, trench-likeopening developed across a saddle betweeen 2 elongate knobs of massive quartz.

| ⓘ Amblygonite Formula: LiAl(PO4)F Colour: White, very pale greenish buff, pale greenish to bluish Description: Scattered through the quartz as crudely formed crystals & irregular masses, some to 5 feet (1.5 meters) diameter; occurs in a smaller cut on the NE end of the dike. |
| ⓘ 'Apatite' Formula: Ca5(PO4)3(Cl/F/OH) Habit: Anhedral Colour: Dark bluish-gray Description: Scattered sparsely throughout the spodumene-bearing zone. |
| ⓘ 'Columbite-Tantalite' Habit: Thin tablets, 1/8 to 1½ inches maximum dimension |
| ⓘ Elbaite Formula: Na(Li1.5Al1.5)Al6(Si6O18)(BO3)3(OH)3(OH) Habit: Rough, prismatic (larger), ½ to 5 inches long; sharply-faced (smaller). Colour: Green, pink Description: Local pod-like concentrations of crystals; smaller crystals as inclusions in lepidolite. |
| ⓘ 'Garnet Group' Formula: X3Z2(SiO4)3 Description: In the outer intermediate zone. |
| ⓘ 'K Feldspar' Habit: Crystals to 4½ feet (135 cm/1.3 meters). Description: Occurs in the mid- or 3rd. intermediate zone. |
| ⓘ 'Lepidolite' Habit: Coarse books to 5 inches (12.5 cm) diameter Colour: Pale pinkish to gray, moderately deep lilac Description: Occurs in both the spodumene- & amblygonite-bearing units, associated with coarse-grained cleavelandite. |
| ⓘ Montebrasite Formula: LiAl(PO4)(OH) |
| ⓘ Muscovite Formula: KAl2(AlSi3O10)(OH)2 |
| ⓘ Quartz Formula: SiO2 Description: Very coarse-grained anhedral masses in the core zone. Large crystals sometimes veined with aggregates of lepidolite so fine-grained that it renders a waxy appearance. |
| ⓘ Schorl Formula: NaFe2+3Al6(Si6O18)(BO3)3(OH)3(OH) Description: In the outer intermediate zone. |
| ⓘ Spodumene Formula: LiAlSi2O6 Habit: Rough, prismatic, less than ½ inch (1.25 cm) to 6 inches (15 cm) thick & 1½ to 24 inches (3¾ to 60 cm) long Colour: Buff to bluish-gray Description: Occurs in the main cut (intermediate zones). Finer grained in the outer intermediate zone. |
