Lithology Comments

Mar 10, 2014 (A Wilson) - One pegmatite body, exposed across a width of 7 feet and for a length of 20 feet, strikes N15°E and dips steeply east. The second body is 175 feet N40°W from the first. It is exposed in two outcrops, 50 feet apart, along a strike of N20°E. In the south outcrop it is 31 feet wide, in the north outcrop, 12 feet wide, with only the east contact exposed. The third pegmatite body is about 100 feet west of the first and is exposed in an outcrop 11 feet across. But, since its contacts are not visible, its true dimensions and attitude are not known. It may possibly represent the south extension of the second body.

Mineralization Comments

Mar 10, 2014 (A Wilson) - The three pegmatite bodies are similar in character. In the outcrops they are made up of unaltered spodumene and some potash feldspar, which occur as phenocrysts in a groundmass of quartz, albite, muscovite, and, in places, a little apatite and tourmaline. The spodumene present makes up 5 to 15% of the pegmatites, and occurs as prismatic crystals up to 6 inches in length. The three pegmatite bodies were tested by diamond-drilling but none was found to contain over 0.5% Li2O. They appear to be truncated at a shallow depth by diabase, the presence of which may account for the occurrence of dark-green altered spodumene in some of the drill cores.
