Jan 29, 2016 (Therese Pettigrew) - A lithtum-bearlng pegmatite dyke cuts coarse-grained monzonite stock wedging out in metasedlments to the south. The pegmatite contains coarse spodumene and potash feldspar crystals in a finer quartz, feldspar, muscovite matrix. The pegmatite strikes N10W dipping 80E for 500 ft. north of Dive Lake. It has an average width of 20 ft (AFRI 42E05SW0006).

Jan 29, 2016 (Therese Pettigrew) - The lithium-bearing pegmatite and associated aplite strikes N10-25W and dips steeply east for a length of 1200 ft. Average exposed width appears to be approximately 20 ft. It is a medium-textured pegmatite containing white albite crystals ranging from 2-4” long and light green prismatic spodumene crystals up to 2” long. Both minerals occur in a fine-grained groundmass of quartz, feldspar, muscovite and minor apatite. The degree of granularity and spodumene content increase gradually inwards from the often ill-defined contacts. A 20 pound sample collected during the 1984 field program assayed 0.43% Li (0.94% Li2O) (AFRI 42E05SW0006). The McVittie pegmatite can be divided into three parts on the basis of its lithia content. One section lies 50-650 feet north of Dive Lake; the central section, 650-850 feet north of the lake; and the third section, 850-1,250 feet north of the lake. The first section, 600 feet in length, ranges from 8 to 26.5 feet and averages 17 feet in width. It is estimated to contain, per vertical foot of depth, 770 tons of pegmatite having an average grade of 1.00 percent Li2O. In the central section, the pegmatite splits into two parallel bodies, each averaging about 5 feet in width. These lie up to 15 feet apart and average 0.68 percent Li2O. From 1,050 to 1,250 feet north of Dive Lake, only a single body is present as before. This section averages 7 feet in width. It is estimated to contain, per vertical foot of depth, about 100 tons of pegmatite having an average grade of 1.25 percent Li2O (Pye, 1965). Highlights of the 1955 drill program include 10 assays that range from 1.44 to 2.08% Li2O (AFRI 42E05SW0006).
