A well-known construction site started in 1994 bordering the NW side of Old Mine Park (Hubbard) Tungsten Mine, both sites have a mineral assemblage unique to the state. The original development as a retail plaza was abandoned and the site sat idle until in late 2009 construction began on a Home Depot store that was completed in January 2011.
This locality, like the neighboring Old Mine Park, is underlain by gently dipping amphibolite and marble. The amphibolite (containing magnesio-hornblende) includes layers and boudins of green albite variety oligoclase and quartz and very coarse-grained fan-shaped aggregates of pale greenish-white marialite with sulfides. Excellent specimens of fluorescent scheelite are found in the amphibolite cut along the east edge of the property, especially where it is altered to a pale gray-brown clinozoisite. The marble contains grossular and diopside.
Cross-cutting high-temperature mineral veins contain the same muscovite-topaz-fluorite var. chlorophane-quartz assemblage found in the surrounding area. Excellent pale to emerald-green beryl crystals are found at the contact of cross-cutting calcite-marialite-clinochlore-fluorite-sulfide veins with the amphibolite, which is metasomatically altered to marialite-phlogopite-quartz-albite along the contact. Heitner (1998) indicates the material recovered was beryl, with no mention of emerald. The occurrence of emerald from this locality remains controversial. Analyses of some of the lighter colored crystals show traces of Cr and Fe with typically more Fe, but not many darker colored crystals have been tested.
Light green beryl was also found in small granite pegmatite stringers less than 7 cm wide.
There are many small brittle faults cross-cutting the host rocks and open cavities in the faults contain excellent poker-chip calcite, purple to green fluorite, sulfides, and quartz. One extremely rusty fault breccia with abundant pyrite and arsenopyrite was exposed near the center of the site.
One word of caution, much rock fill was brought in to grade the site over the years and some collectors unfortunately have contaminated the site with discarded material from other localities. Only minerals found in the host matrix rocks/fault zones should be listed.

✪ Tungstenite ? Formula: WS2 Colour: Dark-Metallic Description: Very rare microcrystals possibly of this mineral occasionally found in marble. Analyses needed.
This ID is very doubtful given that the only report of tungstenite (a rare alteration of scheelite or ferberite) from the adjacent Old Mine Park by Schairer (1931) (a summary of other information) is almost certainly a misspelling of tungstite. The scheelite (or ferberite) is restricted to the amphibolite and does not occur in the marble. These could be primary ferberite micro-crystals (see photos). Reference: J. Zolan Collec. |
ⓘ Tungstite ? Formula: WO3 · H2O Description: Valid tungstite has only been reported in specimens from the 19th century that came from ferberite after scheelite pseudomorphs within adjacent Old Mine Park. The mineral occurs as a yellow alteration within the ferberite crystals. Ferberite has not been found outside of Old Mine Park. Reference: J. Zolan Collec. |
