Jul 13, 2010 (C Ravnaas) - The pegmatite is hosted by the Skidder pluton and Separation Lake metavolcanics. The pegmatite contains tourmaline-garnet-biotite-muscovite-potassic pegmatitic leucogranite with graphic intergrowths of quartz-K-feldspar, there's a gradational contact with medium-grained garnet-biotite-muscovite granite.

Jul 12, 2017 (C Ravnaas) - The ore minerals are cassiterite, manganocolumbite, ferrocolumbite, ferrotapiolite, beryl. The pegmatite contains common minerals: K-feldspar, quartz; accessory minerals include: beryl, muscovite, siderophyllite, cassiterite, apatite, tourmaline, garnet; rare minerals include: lepidolite, ferrocolumbite, manganocolumbite, ferrotapiolite. Bulk analysis of the pegmatite revealed an average of 0.12 wt.% Li2O, 48 ppm Ta, 68 ppm Nb, 667 ppm Rb, 297 ppm Cs, 211 ppm Sn, 15 ppm Be from 18 grab and channel samples (Breaks, Tindle and Smith 1999). manganocolumbite contained 45.51 wt.% Ta2O5, microlite contained 67.90wt.% Ta2O5 and 1.78 wt.% UO2, 1.77 wt.% Sc2O3 and 1.94 wt.% F, cassiterite contained 2.85 wt. TaO5 and 95.90 SnO2.
Jul 29, 2019 (Therese Pettigrew) - The Wolf pegmatite covers a 40 x 100 m area within a west-striking apophysis from the Skidder pluton. The zone consists mostly of tourmaline-garnet-biotite-muscovite potassic pegmatitic leucogranite characterized by graphic intergrowths of quartz-potassium feldspar up to 0.7 x 1 m and abundant coarse books of muscovite up to 5 cm thick. A gradational contact between medium-grained, garnet-biotite-muscovite granite was noted on the north side of the pegmatite mass. Oxide minerals up to 5 mm diameter, identified by electron microprobe analysis as dark brown cassiterite, manganocolumbite and microlite, are mainly confined to small pods and layers of sodic aplite up to 0.8 by 1 m in size. Green beryl is rare. Maximum bulk values of 1000 ppm Cs, 0.016% Ta2O5, 0.024% Nb2O5, 859 ppm Sn, 0.17 % Rb2O and 0.39% Li20, were obtained in the sampling of Champion Bear Resources (Breaks et al., 1999). The best sample from Avalon’s 2015 program was tourmaline-garnet-biotite-muscovite-k-spar pegmatite that ran 0.053% Li2O, 109 ppm Ta2O5, 245 ppm Cs, 261 ppm Nb2O5, and 645 ppm Rb2O (Assessment report 20000014162).
