Jun 09, 2011 (C Papertzian) - The pegmatite is a homogeneous body of tourmaline-bearing graphic granite. The 3 pits were sunk on masses of feldspar. The feldspar is almost exclusively pink microline and toumaline crystals up to 8 cm long can be found in the easternmost pit. Quartz-tourmaline intergrowths are common in the S part of the body. The pegmatite is at least 48 m wide and over 60 m long, hosted in amphibole-quartz-plagioclase gneiss and marble. Prospecting with a scintillometer (1978) failed to indicate radioactive anomalies.
Jun 09, 2011 (A Wilson) - Satterly estimated that the pegmatite dike had an exposed width of 200 feet and a length of about 200 feet.

Jun 09, 2011 (A Wilson) - The feldspar was classified as No. 2 grade at the time of production. Black tourmaline and pink graphic granite are abundant in this deposit. Pink microcline, quartz and less abundantly grey plagioclase are the chief components of the pegmatite. Other minerals include yellow mica, garnet, pyroxene, titanite and zircon.
