Outpost Pegmatite Mine
A Bi-feldspar & traces of Nb-Ta-Sn-V-Pb-Cu-Zn-Mica mine located in the NW¼ of the NE¼ sec. 3, T.7N., R.3W. NOTE: Some references in the literature place this mine in Maricopa County; however, Jahns (1952), Plate I (map) clearly places it in Yavapai Co., about 2 miles North of the county line with Maricopa County.
Owned by Earl F. Anderson & Sidney B. Anderson of Mesa, AZ.
The deposit lies near the west end of a prominent ridge. Mineralization is the Outpost pegmatite, a large, thick pod, the uppermost parts of which have been laid bare by erosion on the north slope of the ridge. Tbhis pod trends north to NNE, appears to dip steeply east, and plunges NNE at a moderate angle. It is curved in plan, and its western margin is broadly convex as exposed on the ridge and on the slope to the south. The north, or crestal, part of the pod is largely concealed by dump material but it appears to split into 2 sub-parallel prongs that are 15 to 70 feet thick immediately north of the mine area.
Bismuth minerals are locally abundant in brecciated and sheared quartz-rich pegmatite.
The country rock is mainly dark-colored hornblende gneiss and quartz-hornblende-biotite gneiss and schist. Chlorite-rich and epidote-rich layers are abundant, and a few thickly tabular masses of greenish, punky-appearing intrusive rock ar also present. A thick inclusion of hornblende schist and gneiss is exposed immediately east of the main cut, and a somewhat larger, more elongate inclusion appears at the W end of the cut. Schorl is abundant in the schist and gneisses near the pegmatite contacts. Most of the country rock is thinly foliated, and this planer structure trends east and dips steeply north.
This pegmatite body is zoned with a thin border zone, outer intermediate zone, inner intermediate zone and a quartz core (see Jahns (1952), pp 94-95 for more detail).
Workings include a bench-like main cut 90 feet long and 35 feet wide and 20 feet deep at the face. There is also a smaller bismuth cut and appended 20 foot incline 60 feet to the east and several irregular trenches, pits & cuts higher on the slope to the S. & E. Bulldozer strippings. Some 1,500 tons of feldspar were stockpiled and about 12 tons of Bi-mineral concentrates were produced.
