MGX Minerals Inc. reported that joint venture partner Power Metals Corp. has announced drill hole assays for lithium (Li) and tantalum (Ta) mineralized intervals for the Main Dyke at Case Lake, east of Cochrane, Ontario. Significant intervals for the Main Dyke include: PWM-17-35: 1.17 % Li2O and 165.34 ppm Ta over 8.0 m; PWM-17-40: 2.07 % Li2O and 213.96 ppm Ta over 18.0 m; PWM-17-40: 2.81 % Li2O and 143.33 ppm Ta over 7.0 m. Power Metals has also announced drill hole assays for the two new spodumene pegmatite dykes that were discovered down hole of the Main Dyke near the end of the 2017 drill program. The first new dyke was intersected in PWM-17-42 and 43 and then targeted to intersect it again in PWM-17-44 and 49. This new dyke is located 20-40 m down hole from the Main Dyke and 35-40 m vertical depth from the surface. The second new dyke was intersected in PWM-17-42 and 49. It is located 50 m down hole from the Main Dyke and 50-80 m vertical depth from surface. Both new dykes are open in all directions. Drilling is required to define these new dykes. Assay highlights for the first new dyke include: PWM-17-42: 0.99 % Li2O and 88.33 ppm Ta over 3.0 m; PWM-17-43: 0.85 % Li2O and 94.10 ppm Ta over 1.15 m; PWM-17-44: 1.11 % Li2O and 73.0 ppm Ta over 6.42 m.
