The Pontax lithium spodumene pegmatite dyke (LSPD) project is a 100% owned property by Stria. It is located in the west-central Eeyou Istchee Baie-James (EIBJ) Territory in northern Québec.

Stria launched its first full drilling program at Pontax in 2017, completing seven holes for a total of 911.4 m. All seven holes intersected spodumene-bearing pegmatite dykes grading from 0.65% Li2O to 2.49% Li2O over a min. of 1.0 m. The best intercept was 21.39m grading 1.16% Li2O in drill hole 975-17-0142.1

Historic work done on the property:

  • Prospecting and outcrop sampling
  • Geological mapping and airborne geophysical surveying
  • Mechanical trenching and channel sampling
  • Sample core drilling: drill hole 09-555-05 returned 0.97% lithium oxide (Li2O) over 21.0 m (core length), including 1.43% Li2O over 13.0 m (from 36.0 m to 49.0 m)1

Q1 2020 Drilling Program Highlights:2

  • Eleven drill holes completed for a total of 1,510.5 m drilled
  • Ten (10) of the 11 holes intersected pegmatite dykes with significant spodumene mineralization
  • Hole 975-19-018 intersected 11.27 m grading 0.91% Li2O, including a subintercept of 2.84 m grading 1.72% Li2O
  • Hole 975-19-020 intersected 3.36 m grading 2.55% Li2O in, at a vertical depth of 13.58 m
  • Hole 975-19-016 intersected two bands of spodumene pegmatite dykes, the first grading 1.45% Li2O over 1.61 m and the second grading 1.11% Li2O over 2.10 m
  • Hole 975-19-022 intersected 3.89 m grading 1.28% Li2O at a vertical depth of 31.2 m, while Hole 975-19- 016 intersected 1.61 m grading 1.45% Li2O
  • The spodumene pegmatite dyke swarm at the Pontax LSPD prospect extends over a min. distance of 650 m and is open along strike to the northeast and at depth, while thinning out toward the southwest.

Next Steps

  • The Property remains largely unexplored for new lithium spodumene dyke occurrences. We are just getting started.
  • Stria is working on a first major phase of a 10,000 m infill and step-out drilling program at Pontax in 2022, using findings from past exploration to optimize drill program design.
  • The objective is to expand the dyke swarm to the Northeast and improve confidence in the lateral and downwards continuity of the spodumene mineralization.

In June 2022, Stria received a $275,000 grant from the Government of Quebec to conduct a geometallurgical study of lithium-bearing spodumene pegmatites at its Pontax property in the coming months.
