LITHIUM: Doris discovery at Whabouchi yields nice grades for Nemaska

QUEBEC – Nemaska Lithium of Quebec City has provided results from drilling at the newly discovered Doris zone on its Whabouchi lithium project 300 km northwest of Chibougamau. The new zone lies in the southwest end of the planned pit area. It contains five interconnected dykes along a 420-metre lateral extension and up to a depth of 440 metres.

The 4,000-metre drill program at Doris returned widths and grades similar to the main Whabouchi deposit. Many holes had multiple intersections including the following (true widths):

  • 74% Li2O over 20.9 metres;
  • 58% Li2O over 16.3 metres;
  • 40% Li2O over 33.0 metres; and
  • 78% Li2O over 3.3 metres.

Nemaska intends to add the Doris zone to resources soon. The Whabouchi deposit already has measured and indicated resources of 28.0 million tonnes at an average grade of 1.57% Li2O plus an inferred resource of 4.7 million tonnes at 1.51%.
