Setting:
A rare-earth-element (REE)-gemstone-specimen producing pegmatite occurrence/mine located in the NWΒΌSWΒΌ Sec. 33, T6S, R2E, SBM, 2.3 km (1.4 miles) E of Little Cahuilla Mountain (coordinates of record), 3.3 km (2.0 miles) N of Cahuilla Mountain (coordinates of record) and 8.3 km (5.1 miles) NNW of Cahuilla (town), on private (patented) land within a National Forest. MRDS database stated accuracy for this location is 100 meters.

History:
The deposit was first discovered by Bert Simmons in 1902, and is best known for its production of well-crystallized schorl and gem aquamarine, as well as pink tourmaline and spodumene. Two contiguous lode mining claims (Big Pink and Little Blue lodes; MS 4800) are commonly referred to as the Fano Mine, and aggregate approximately 37.54 acres. The property is private land, patented January 29th, 1912 by the Fano Kunzite Tourmaline Mining company.

Geology/Mineralogy: The ore body is a pegmatite dike that strikes NW and dips 20SW at a width of 2.44 meters. Local rocks include Mesozoic gabbroic rocks, unit 2 (undivided) and/or pre-Cenozoic granitic and metamorphic rocks undivided.

Workings: Workings include surface and underground openings. The deposit has been developed by numerous surface cuts, trenches, and minor underground drifts along the paystreak.
