Point Location Description: Point located from 2011 assessment report (Tuomi 2012, AFRI 20000007852)
Location Method: Based on Assessment
Access Description: Approx. 30 km NE of Lake Nipigon and accessed from Armstrong by an all-weather gravel road running east for 100 km, then by logging roads and ATV trails.
Prospectors found very old blasted pits near the showings. No record of these pits was found in the assessment files. 1983: Kerr Addison Miles did reconnaissance exploration in the Summit Lake area consisting of geological mapping and soil sampling. 1999: Inco Ltd. and Ninety Nine Resources conducted initial prospecting, finding anomalous values of Ni, Cu and PGEs.1989: OGS flew airborne EM and total intensity magnetic geophysical surveys over the Tashota-Geraldton-Longlac area. 2001: Berland Resources Ltd. acquired 100% interest in the property from Ninety-Nine Resources in September and commissioned M.P. Lewis Geological Services to carry out geological mapping. Stares Contracting Corporation was hired to carry out prospecting at the same time. 2006: Landore Resources Canada Inc. optioned the property from Stares Corp. in June. 2009: Landore undertook a mapping and sampling program. 2010: Landore conducted prospecting during October. 2011: Landore drilled 10 DDH totalling 1,441 m, 5 of which holes (675 m) targeted the Li-rich pegmatite dyke.

Sep 30, 2014 (Therese Pettigrew) - Berland Resources considered the Swole Lake pegmatites as an extension of the Crescent Lake pegmatite field, which is 10 km to the west of Swole Lake. At Swole Lake, 9 large subangular (2 m x 2 m) blocks of pegmatite were discovered within a 25 m x 25 m area (Berland Resources press release, Nov 8 2001). The pegmatite erratics are comprised of coarse-grained milky white feldspar (40%), medium to dark purple lepidolite (25%), quartz (15%), spodumene crystals (10%), mica (3-4%) and minor amounts of adularia and tantalum. Tantalum crystals occur as 0.5 cm long needles and tabular crystals. The erratics are inferred to be in place because 1) the apparent cluster of the pegmatite and host metasediment erratics and 2) the largest of the pegmatite erratics is in contact with the host metasediment (McCrindle, 2001 AFRI 42L05NW2008).

Sep 30, 2014 (Therese Pettigrew) - Nine grab samples were taken from the pegmatites during prospecting in 2001: Sample 14151: 105 ppm Cs, 61 ppm Nb, 1030 ppm Rb, 289 ppm Ta, 1150 ppm Li Sample 14152: 91 ppm Cs, 46 ppm Nb, 1040 ppm Rb, 159 ppm Ta, 4620 ppm Li Sample 14153: 30 ppm Cs, 57 ppm Nb, 225 ppm Rb, 288 ppm Ta, 205 ppm Li Sample 14154: 62 ppm Cs, 51 ppm Nb, 873 ppm Rb, 152 ppm Ta, 835 ppm Li Sample 14155: 44 ppm Cs, 88 ppm Nb, 796 ppm Rb, 201 ppm Ta, 166 ppm Li Sample 14156: 37 ppm Cs, 41 ppm Nb, 551 ppm Rb, 164 ppm Ta, 36 ppm Li Sample 14157: 109 ppm Cs, 59 ppm Nb, 696 ppm Rb, 175 ppm Ta, 1460 ppm Li Sample 14158: 6 ppm Cs, 21 ppm Nb, 26 ppm Rb, 200 ppm Ta, <10 ppm Li Sample 14161: 63 pm Cs, 46 ppm Nb, 475 ppm Rb, 248 ppm Ta, 513 ppm Li (McCrindle, 2001 AFRI 42L05NW2008). During the 2010 prospecting, grab and channel samples were collected. Samples returned average values of 0.41% Li2O with maximum values up to 0.72% Li2O. Historic sampling of the boulder field had returned up to 0.99% Li2O. Also noted in the Swole Lake pegmatite is the tantalum-bearing mineral columbite-tantalite, which has been observed as small tabular crystals comprising less than 1% of the overall composition of the pegmatite. The Swole Lake pegmatite is located east of a number of tantalum occurrences, namely the Zigzag Lake and the Seymour Lake occurrences (Tuomi, 2011 AFRI 20000006844). 2011 drilling confirmed the presence of a pegmatite dyke, which is thought to strike NE-SW. Drilling results included the following intersections: DDH 0411-304: 8.8 m at 1.14% Li2O, 0.13% Ta2O5; 3.1 m at 1.12% Li2O, 0.018% Ta2O5; DDH 0411-305: 3.3 m at 0.56% LI2O, 0.32% Ta2O5; DDH 0411-308: 2.4 m at 0.77% Li2O, 0.022% Ta2O5. Samples were analysed for Rare Earth Elements (REEs), however, no significantly elevated results were received (Tuomi, 2012, AFRI 20000007852).
