Stria Lithium reports promising assays from first at-depth drilling on Quebec Pontax Property

Stria Lithium Inc. (TSXV:SRA) announced promising assay results from the first two drill holes at depth on the Pontax Lithium Project (“Pontax”) in the James Bay region of Québec, Canada.


  • Winter road has been opened to the Pontax site; multiple drill rigs are now on site with the aim of establishing a maiden resource by mid-2023
  • Drilling is being financed and conducted by Cygnus Gold Ltd. of Australia
  • Pontax Central is an extensive spodumene-bearing pegmatite swarm, over 700m of strike

Assays include 10.2 m (true width) at 1.34% Li2O, and a doubling of the depth of known mineralization to 230m. These results further confirm previous exploration activities on the site and are only the first results of 14 holes drilled to date, totalling 3,858 metres, as part of an aggressive 15,000-metre definition and exploration drilling program now under way on Stria’s Pontax property in the west-central Eeyou Istchee James Bay (EIJB) Territory. A winter road has been opened from the main highway to the Pontax site, and mutiple drill rigs are now on site with the aim of establishing a maiden resource by mid–2023. Assays from the remaining 12 holes are currently pending at the laboratories.

The drilling program at Stria’s Pontax property is being financed and conducted by Stria’s project partner, Cygnus Gold Ltd. of Australia, and has been designed to systematically step out from known mineralisation at Pontax Central – an extensive spodumene-bearing pegmatite swarm which outcrops over 700m of strike.

Significant intersection results from the latest drilling include;


  • 2.82 m* (4.3m of core length) @ 1.84% Li2O** at a depth of 158 metres(from 227.6m to 231.9m)
  • 6.04 m* (9.21m core length) @ 1.44% Li2O** at a depth of 172 metres (from 247.1m to 256.3m)
  • Five (5) minor intervals of true width between 1.51m* and 2.02m* @ 0.84% to 1.46% Li2O**
  • Cumulative true thickness of mineralized dyke of 4 metres


  • 3.44 m* (5.7m of core length) @ 1.35% Li2O** at a depth of 144 metres (from 194.3m to 200.0m)
  • 8.54 m* (13.3m of core length) @ 1.34% Li2O** at a depth of 212 metres (from 300.2m to 313.5m)
  • Three (3) minor intervals of true width between 1.08m* and 1.55m* @ 0.67% to 0.82% Li2O**
  • Cumulative true thickness of mineralized dyke of 9 metres

*: True thickness, assuming the dykes are dipping -85o to the NNW

**: Weighted average using a cut-off grade of 0.5% Li2O on spudumene dyke only, excluding lithium bearing wallrock (FeO > 5%), a minimum true thickness of 1 metre, no external dilution, and wallrock internal dilution set at 0% Li2O.

Drilling was conducted with a single heliportable rig by RJLL Drilling Co. from Rouyn-Noranda and supervised by IOS Services Geoscientifiques Inc. Collar location was measured with a high resolution GPS Geode device, while downhole deviation was measured with the use of a Reflex device. Core, NQ in diameter, has been logged on site and expedited by road carrier to IOS facilities in Saguenay, Quebec, for sampling and storage. Core samples were cut in half with a diamond saw, tagged and bagged to be shipped to SGS Lakefield laboratory by road carrier for preparation.

Core samples were crushed (75% <2mm) and pulverized (85% <75μm). Assaying has been conducted by SGS Burnaby with the use of ICP-OES and ICP-MS after sodium peroxide fusion (GE_ICM91A50). SGS-Canada is an ISO/IEC 17025 accredited laboratory. Quality control has been monitored by an IOS certified chemist through the insersion of 7 sample blanks, 7 preparation blanks, 5 certified reference material Oreas-147, 4 certified reference material Oreas-148 and 5 certified reference material Orea-149, for a total of 28 insertions (15%).

Dean Hanisch, CEO of Stria Lithium, said today:

“We are excited to be finally getting an aggressive drilling program at depth under way, and are very encouraged by the promising results of the first two holes of 14 drilled to date. The winter road is open and providing economical access to several additional heavy drill rigs. We look forward to reporting more assay results as they become available.”

The latest drilling has stepped out 50m to 100m below existing mineralisation to a vertical depth of 230m, effectively doubling the depth of known mineralisation which remains open in all directions.

Interval length expressed as true thickness and depth as vertical depth. The recent drilling is the deepest drilling on the project to date stepping out over 100m from exisiting drilling with mineralisation remaining open in all directions.
