OTTAWA, ONTARIO – October 20, 2022 – Stria Lithium Inc. (TSXV:SRA) (“Stria” or the “Company”) in partnership with Cygnus Gold Limited (ASX: CY5) (“Cygnus”) is pleased to announce highly promising preliminary results from the recently completed high resolution aeromagnetics and LiDAR surveys at the Pontax Lithium Project located in the prolific James Bay lithium province, Quebec.
The LiDAR and high resolution aeromagnetic surveys were completed over the Pontax Property that was optioned to Cygnus Gold in July 20221, Cygnus being the operator of the project This recent work is the first regional exploration to be conducted on the project in over a decade and signifies the first steps in a comprehensive and systematic exploration program to be carried out by the company.
Detailed magnetics interpretation and LiDAR has generated numerous walk-up targets which will be mapped in the coming week as our earn-in partners Cygnus and IOS Services Geoscientifiques deploy geologists to start work on the ground for the first time. The Autumn mapping and sampling program aims to generate further regional targets to be followed up in the upcoming drilling campaign expected to commence in early November 2022.
The Pontax project has the potential to create significant value for shareholders because high-grade lithium spodumene bearing pegmatites have already been identified through drilling and there is significant scope to continue growing the economic potential through exploration.

This early-stage exploration will underpin the 10,000m drilling campaign commencing in early November. Cygnus plans to complete both resource definition and step out drilling over the next six months.
LiDAR and Magnetic Results
Results from the first stage of exploration at the Pontax Lithium Project have now been received ahead of the mapping campaign due to commence later this month. This work includes recently flown high resolution aeromagnetics alongside LiDAR and high-resolution aerial photography. This is the first time the project has been systematically explored using fundamental exploration tools, in particular for regional targeting. Results from this work has delivered numerous walk-up targets which the team will map and sample over the next month, delivering further regional targets ahead of the 10,000m drill campaign.
Detailed airborne magnetics is crucial in understanding project scale geology especially in areas with high amounts of cover. The recently acquired magnetics is currently being interpreted and will be used to underpin the geological interpretation of the belt and assist with regional targeting. A main focus is delineating the metavolcanic-metasedimentary belts which are known to be the preferred host rock for LCT pegmatite emplacement. Already with the preliminary results the geological understanding has been significantly improved, with the team able to delineate potential repetitions of the prospective mafic horizon throughout the 10km trend which to date had not been formally recognised. Mafic volcanic horizons are recognized as preferred loci for pegmatite emplacement, due to their brittleness.
LiDAR and high-resolution imagery have also provided a comprehensive assessment of the terrane and outcrop coverage throughout the Pontax Lithium Project. Multiple walk-up targets have been generated that are similar looking to known outcropping pegmatites and that have never been mapped or sampled. These outcrops are a high priority for the upcoming mapping campaign.
Collectively, the geophysics and LiDAR results has demonstrated that the project remains dominantly unexplored, covered by sparse low-level vegetation and abundant marshy areas. The LiDAR generated a high-quality digital elevation model (DEM) which has identified multiple areas of elevated topography along prospective trends that may represent areas of outcrop beneath thin vegetation. These are significant targets for stripping and trenching as exploration advances.

Pontax Lithium Project (CY5 Earning Up To 70%): Located in one of Canada’s most prolific lithium provinces
The Pontax Lithium Project was acquired for it’s potential to host a substantial lithium Resource. The Project is located in the prolific Superior Province of Quebec, with the James Bay region one of the most endowed lithium terranes in the world, even though only minimal modern exploration has been seen over the past 20 years.
Pontax: – Unlocking the Potential
The Pontax Lithium Project is host to a significant pegmatite occurrences which outcrops over 620m of strike and remains open along strike and at depth. There are untested pegmatite outcrops north of the central outcrop that have never been drilled and multiple targets for follow up drilling.
To date 25 diamond drill holes for ~3,286m have been completed at the project with drilling entirely focussed upon the known extent of the outcrop. All holes drilled to date have hit spodumene bearing lithium-cesium-tantalum (LCT) pegmatites with significant drill intersections including (Refer to Cygnus Gold ASX announcement 29 July 2022)1:
- 9m @ 1.7% Li2O from 46.9m
- 15.6m @ 1.6% Li2O from 83.9m
- 4.8m @ 2.6% Li2O from 19.4m
- 13.0m @ 1.4% Li2O from 36.0m
- 12.0m @ 1.1% Li2O from 99.5m
- 12.0m @ 1.4% Li2O from 83.0m
- 7.9m @ 1.4% Li2O from 88.9m
- 4.1m @ 2.5% Li2O from 64.3m
The mineralisation at Central Pontax is open in all directions with some of the thickest intervals returned from the deepest drilling which is still shallow at less than 130m vertical depth.
