Power Metals Corp. announced that drill holes intersected, for assays received to date, more impressively wide high-grade lithium (Li) and tantalum (Ta) mineralized intervals for the Main Dyke at Case Lake, east of Cochrane, Ontario. PWM-17-33: 2.19 % Li2O and 195.27 ppm Ta over 6.0 m (5.0 to 11.0 m). PWM-17-33: 2.11 % Li2O and 259.31 ppm Ta over 11.0 m (22.0 to 33.0 m). PWM-17-34: 1.81 % Li2O and 136.10 ppm Ta over 17.0 m. Drill hole PWM-17-33 has impressive lithium and tantalum mineralization. Lithium grades are up to 3.02 % Li2O over 2.0 m and 2.84 % Li2O over 4.0 m in PWM-17-33. Tantalum grades are up to 554.0 ppm Ta over 2.0 m in PWM-17-33. The high-grade coarse-grained spodumene inner intermediate zone from 5.0 to 11.0 m is followed by a very coarse-grained white K-feldspar and pure quartz core (11.0 to 22.0 m) and by another high-grade coarse-grained spodumene inner intermediate zone from 22.0 to 33.0 m. This indicates that the high-grade spodumene pegmatite zone is concentrically zoned around the quartz core. The Main Dyke in this hole has a narrow low-grade outer pegmatite zone and the total width of the Main Dyke in PWM-17-33 is 32.65 m. Drill hole PWM-17-34 also has an impressive width of 17.0 m of continuous lithium and tantalum mineralization. Lithium grades are up to 2.59 % Li2O over 1.0 m and 2.42 % Li2O over 2.0 m. Tantalum grades are up to 264.25 ppm Ta over 4.0 m. The Main Dyke in this hole has a second high grade lithium zone of 1.79 % Li2O over 3.0 m. Including the narrow low-grade outer pegmatite zone and the total width of the Main Dyke in PWM-17-34 is 27.5 m. The Main Dyke is consistently 30-35 m exposed on surface and in shallow drill holes. With depth, the Main Dyke becomes multiple spodumene pegmatite dykes separated by tonalite, but still within the same 30-35 m envelop of mineralization. Additional high-grade lithium intervals include: PWM-17-16: 1.12 % Li2O and 119.03 ppm Ta over 7.0 m. PWM-17-19: 2.56 % Li2O and 47.50 ppm Ta over 1.14 m. PWM-17-22: 2.95 % Li2O and 255 ppm Ta over 1.0 m. PWM-17-22: 2.40 % Li2O and 35.45 ppm Ta over 2.0 m.
