LITHIUM: Case Lake gives up 40% spodumene on surface for Power Metals

ONTARIO – Vancouver’s Power Metals Corp. has made an encouraging new discovery of a zone grading up to 40%  spodumene near the surface at its Case Lake lithium project 80 km east of Cochrane and 100 km north of Kirkland Lake.

The exploration team peeled back thick moss to discover abundant coarse grained spodumene crystals on the south outcrop of the Northeast dyke whereas the one previous historic grab sample had no spodumene. The outcrop appears to be at least 3 to 6 metres wide and have a strike length of 70 metres.

Prospecting and peeling moss also revealed that the north outcrop of the Northeast dyke contains megacrysts of spodumene.

In September 2017, Power Metals released results from three drill holes at Case Lake. The holes tested the up and down dip extension of the Main dyke.

  • PWM-17-08 intersected continuous spodumene pegmatite from 18.86 to 54.08 metres;
  • PWM-17-09 intersected continuous spodumene pegmatite from 26.5 to 60.0 metres, including a 42-cm long x 2-cm wide pale green spodumene blade; and
  • PWM-17-10 intersected spodumene pegmatite from 33.83 to 62.05 metres, including two sections of Case Batholith host rock: 2.99  and 0.62 metres long.

The Case Lake pegmatite swarm consists of five dykes. Details are available at
