Stria Lithium reports highly anomalous Tantalum oxide grain

counts in till samples suggestive of the proximity of lithium

bearing pegmatite on its recently acquired Pontax II property.

Stria Lithium, Inc. (TSX.V: SRA)

Ottawa, ON June 29, 2023 – Stria Lithium Inc., an emerging resource exploration company

developing Canadian lithium reserves to meet legislated demand for electric vehicles and their

rechargeable lithium-ion batteries, is pleased to announce the results of tantalum oxide grain

counts survey over part of its recently acquired Pontax-II project. Heavy mineral concentrates

from 38 glacial till samples collected in 2019 for the purpose of gold grain counting were

reprocessed to evaluate the abundance of tantalum oxide grains with the use of an automated

scanning microscope based on a proprietary technology by IOS Services Géoscientifiques Inc.

Tantalum oxides (tantalite, columbotantalite, wodginite and micronite ) are a class of mineral that almost

exclusively form in lithium bearing pegmatite (or LCT pegmatite), such as those currently being evaluated at

the nearby Pontax-Central occurrence (Stria Lithium under option by Cygnus (Avenir) Metals), as well as the

James Bay Lithium project (formerly Cyr Lithium by Allken Mining), the Rose project (Critical Element

Lithium Corporation) or the Wabouchi mine (Némaska Lithium). Of these samples, a total of 5950 tantalum

oxide grains were observed, for an average of 156 gr ains per samples. As a comparative basis, a regional

survey in the same area conducted by the Ministère de l’Énergie et des Ressources Naturelles du Québec,

processed using the same technology, yielded an average count of 36 grains per samples, meaning the average

sample from Pontax -II stands at the 97.6 centile of the regional population. Samples from Pontax includes

tantalum oxide counts up to 797 grains, the highest count ever recorded by the laboratory. The high counts

samples are clustered into two distinct kilometer-scale groups (figure 1), suggestive of two distinct sources.

As these counts are not down -ice from the Pontax -Lithium occurrence, originating from this occurrence is

ruled-out. As per comparison, somewhat smaller isolated counts from the ME RNQ survey were at the origin

of Li -FT Power ’ Pontax and Rupert project, where the relation between tantalum dispersion and lithium

sources was confirmed (figure 2 ). Similarly, an orientation till survey conducted at Stria’s Pontax -Lithium

occurrence by Cy gnus Metal highlighted a dispersion of similar size and intensity directly adjacent to the

deposit of what is reported here.

Dean Hanisch, CEO of Stria Lithium, said today: “These results caught us by surprise, since we basically

demontrated the potential of the property to host fertile pegmatite occurrence within months of its acquisition!

If you look at the map of the overall till samples of the region in relation to our numbers and then you match

that with the similar footprint at Pontax Central that was drill tested, it’s really exciting. We are anxious to

send a team of geologists to conduct a prospect as soon as the forest fire situation allows us . We feel very

fortunate to lean on the proprietary technology developed by IOS and their years of experience in this region.

This scanning electron machine is the only one of its kind in the world and is invaluable in making calculated

decisions that save time and money.”

About Stria Lithium

Stria Lithium (TSX-V: SRA) is an emerging resource exploration company developing Canadian lithium reserves in the

Eeyou Istchee James Bay Territory of Québec, Canada, to meet legislated demand for electric vehicles and their

rechargeable lithium-ion batteries.

Lithium is a rare metal and an indispensable component of rechargeable lithium-ion batteries, one of the safest and most

efficient energy storage technologies available today, used in everything from cell phones and power tools to electric

cars and industrial-scale energy storage for renewable power sources such as wind and solar generation.

Stria’s Pontax-II Project covers 55 square kilometres, approximately 25 kilometres to the west-south-west of Pontax-

Lithium and is located adjacent to the Billy-Diamond paved highway. The Eeyou Istchee James Bay Territory of

Québec, where the project is located, is one of only a few known sources of lithium available for hard rock mining in

North America.

As momentum builds for the green energy revolution and the shift to electric vehicles, governments in Canada and the

U.S. are aggressively supporting the North American lithium industry, presenting the industry and its investors with a

rare, if not unprecedented, opportunity for growth and prosperity well into the next decade and beyond.

Stria is committed to exceeding the industry’s environmental, social and governance standards. A critical part of that

commitment is forging meaningful, enduring and mutually beneficial relationships with the James Bay Cree Nation

(Eeyouch), and engaging openly and respectfully as neighbours and collaborators in this exciting project that has the

potential to create lasting jobs and prosperity for Eeyou Istchee and its people.

The technical content disclosed in the current press release was reviewed and approved by Réjean Girard, P.Geo and

president of IOS Services Geoscientifiques Inc, a qualified person as defined under National Instrument NI-43-101.
