The Little Joe No. 2[1] is an adit driven southwesterly into the Stewart pegmatite for several hundred feet using mechanized haulage to develop a series of inclined room and pillar crosscuts that encountered several major pockets containing gem quality crystals of fine rubellite, morganite, and kunzite; associated with accessory minerals such as lepidolite, quartz, and montmorillonite. The adit was originally a short exploratory drift developed by the American Lithia and Chemical Company circa 1907, which was reported to have produced light pink kunzite and some gem tourmaline. These workings were later widened and extended further down dip between the late 1980's and early 90's. The adit and underground workings are located on the patented Stewart mine property. Elevation approx. 1069' AMSL.

1.The adit was named in honor of the fictional character Little Joe Cartwright, from the popular American television series "Bonanza", a Western themed show which aired on NBC from 1959 to 1973.
