Stria’s joint venture partner Cygnus Metals has completed a

Maiden Resource on the Pontax Central property with an

announcement of a JORC maiden inferred mineral resource

estimate of 10.1Mt at 1.04% Li2O stating mineralisation is open

in all directions

Stria Lithium, Inc.

(TSX-V: SRA, OTC: SRCAF, and FRANKFURT: S35A)

Ottawa, ON, August 14, 2023 - Stria Lithium Inc. (TSXV: SRA) (“Stria Lithium”, the

“Company”) The Pontax Central Project Joint venture (Cygnus Metals 51%/Stria 49%) now

has a maiden resource estimate produced by Cygnus metals. This JORC estimate establishes

Pontax Central as a serious player in the Canadian Lithium James Bay region. Cygnus Metals

being an ASX issuer, they adhered to Australian JORC Code 2012 guidelines , meaning that

such mineral resource estimate is not necessarily current in regard of the Canadian National

Instrument 43-101 code. Cygnus published a Maiden inferred Resource Estimate (MRE) of

10.1Mt at 1.04% Li2O based on the central area of the known mineralisation.

Below are highlights from Cygnus Metals press release dated August 14, 2023

• Substantial maiden resource establishes Pontax as a significant James Bay lithium project with

scope for ongoing growth

• Diamond drilling scheduled to resume this quarter and will be focused on resource growth

through step out drilling and discovery drilling across the wider belt

• The mineralisation is reported as open in all directions

• Spodumene mineralisation has been confirmed by surface mapping up to 9km from the Pontax

Central resource, highlighting the huge upside potential at Pontax

• The Resource has been defined in just 12 months since acquisition at an exceptionally low

discovery cost of A$0.55 per tonne of Resource, based on only 11,328m of drilling

• Cygnus is only the fourth ASX -listed company in the Quebec region with a lithium resource

after Allkem (ASX:AKE), Sayona (ASX:SYA) and Patriot Battery Metals (ASX:PMT)1

• First pass metallurgical test work delivered excellent recoveries, generating a 6% spodumene

concentrate using conventional processing techniques2

• Pontax Central is located in central James Bay close to a major paved road and Hydro Quebec

power infrastructure and only 30km south of Allkem’s James Bay Deposit (40.3Mt @ 1.40%

Li2O),1 which is progressing towards development.

Figure 1: Pontax is located in central James Bay, close to major infrastructure and power, and surrounded by significant

developing lithium projects including Allkem’s (AKE) 40.3Mt James Bay deposit located just 30km to the north of Pontax.1

“We are extremely impressed with the speed and efficiency in which Cygnus Metals established this

JORC maiden resource estimate. With only 11328 metres of drilling and a cost of $0.49 CDN per

tonne of resource we can conclude that this strategy is extremely beneficial to investors in creating

real value in the ground per dollar of investment.” Dean Hanisch CEO of Stria Lithium.

About Stria Lithium

Stria Lithium (TSXV.SRA, OTCQB.SRCAF, FRANKFURT.S35A.F) 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 met al 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 stor age for renewable power sources such as

wind and solar generation.

Stria’s Central Pontax Lithium Project covers 36 square kilometres, including 8 kilometres of strike along

the prospective Chambois Greenstone Belt. The region, known as the Canadian “Lithium Triangle,” is one of

only a few known sources of lithium available for hard rock mining in North America.

Stria has entered into a JV agreement with Cygnus Metals (ASX:CY5) on its Pontax Central project. Cygnus

Metals is committed to fully funding and managing the current two-stage exploration and drilling program to

a maximum of $10 million at Stria’s Pontax property, and will also pay Stria up to $6 million in cash. In

return, Cygnus may acquire up to a 70% interest in the property. Cygnus has fulfilled its stage 1

requirements within the agreement and has now earned its 51% interest in the property as per above share

issuance.

Stria’s other significant project, Pontax II is due southeast to Pontax Central. These 128 individual claims

totalling 6811 hectares (68 square kilometres) are on strike with stria’s existing Pontax Central project along

the prospective Chambois Greenstone belt hosting spodumene bearing pegmatites. Stria Lithium previously

reported highly anomal ous tantalum oxide grain counts in till samples up to 797 grains, the highest count

ever recorded by the laboratory. The Pontax II grain counts stand at the 97.6 centile of the regional

population with an average of 156 grains per sample as a comparative b asis, a regional survey in the same

area conducted by the Minist ère de l’ Énergie et des Ressources Naturelles du Qu ébec, processed a total of

5950 tantalum oxide grains yielding an average count of 36 grains per samples. The conclusion being the

grain counts are suggestive of the proximity of lithium bearing pegmatites. Chip sampling and mapping is

underway summer 2023 (currently) in preparation for a follow up winter drill program.

Pontax II claims are in highly active prospective zones, situated to the west southwest of Stria/Cygnus

lithium discovery and situated to the west of the Patriot Battery Metals (PMET.V) Pontax project, and south

of Brunswick Exploration (BRW.V).

Stria’s Pontax properties are both situated close to an industrial powerline and a major paved highway, about

310 km north of the North American rail network that leads to the industrial heartland.

As momentum builds for the green energy revolution and the shift to electric vehicles, gov ernments 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.
