Stria Lithium reports 11.27 m grading 0.91% Li2O in Hole 975-19-018 from Q1 2020 Drilling

at Pontax Lithium, Québec – includes 2.84 m sub-intercept grading 1.72% Li 2O

KINGSTON, ONTARIO – December 2, 2021 – Stria Lithium Inc. (TSX-V: SRA) (OTCQX: SRCAF)

("Stria" or the "Company") is pleased to report the results from the first six drill holes from the

Company’s Q1 2020 step-out drilling program at its Pontax Lithium Property (the “Property”)

located in west-central Eeyou Istchee James Bay Territory, Northern Québec. This most recent

drilling program targeted the Pontax spodumene pegmatite prospect , the main occurrence of

lithium spodumene pegmatites discovered on the Property to date. The drilling was designed to

test the north-eastern and south-western extensions of the spodumene pegmatite zone at a 50

m spacing, as well as to test for dykes inside the footwall of the zone towards the northwest.

Analytical results for the five remaining drill holes are expected in the coming weeks.

Highlights:

 Eleven BTW-diameter drill holes were completed for a total of 1,510.5 m drilled (Table

1), with the results of the first six holes being released today.

 A total of 654.3 m of core were sampled and submitted for multi-element geochemical

analysis for the current program, of which 189.3 m (29%) represent spodumene bearing

pegmatite.

 Results are for two of the five drill holes positioned to test the extension of the

spodumene pegmatite dyke swarm to the Northeast and for four of the five holes

targeting a second series of pegmatite dykes to the Northwest of the Pontax

spodumene pegmatite prospect. Results from the only step out hole to the Southwest

are pending. All six holes reported today intersected spodumene bearing pegmatite

dykes grading up to 3.77% Li2O over a minimum true thickness1 of 0.7 m (Table 1).

 Best intersection1: Hole 975-19-018, drilled at -50 o to a vertical depth of 101.0 m on Line

5+50N near the northeastern end of the spodumene pegmatite bearing zone,

intersected numerous closely spaced dykes, wth the best intercept being 11.27 m

grading 0.91% Li 2O at a vertical depth of 56.28 m (from 80.4 m to 96.5 m; core length:

16.1 m; Table 1), including:

o 2.84 m1 grading 1.72% Li2O (from 84.8 m to 88.85 m; core length: 4.05 m)

 High-grade intercept in Hole 975-19-020, drilled on Line 5+00N at -50 o degrees to a

vertical depth 13.58 m, with 3.36 m 1 grading 2.55% Li 2O (from 19.4 m to 24.2 m; core

length: 4.8 m).

 The spodumene bearing pegmatite dyke swarm remains open along strike to the

northeast and at depth, while thinning out toward the southwest, with a decrease in

lithium grades in the footwall towards the Northwest.

 Metabasalt wall rocks were excluded from intersection calculations despite being locally

lithium bearing due to the presence of iron bearing holmquisite which is not amenable

to lithium hydroxide production.

1True thicknesses are reported in this news release. The drill holes have been loaded into a 3-D visualization

software and the three-dimensional envelope of the mineralized zone has an azimuth of N325 o and dips vertically.

Drill holes crosscut the envelope of the mineralized zone at an angle of approximately 45 o degrees. The conversion

factor for true thickness is 0.7 of the core intersection length.

“We are encouraged by the initial results from our first round of step-out drilling at the Pontax

spodumene pegmatite prospect, which confirms the pegmatite swarm extends over a minimum

strike length of 600 m and to a minimum depth of 100 m and is still open to the northeast,” said

Jeffrey York, acting President and CEO of Stria. “These latest drilling results will be integrated

with the results of our 2017 drilling program to design the next phase infill and extension

drilling targeting the Pontax spodumene pegmatite dyke swarm.”

A map showing the location of the drill holes and main mineralized intercepts along with dril l

sections are available on the Company’s Website at: http://strialithium.com.

The Q1 2020 drilling program was designed based on the results of the Company’s December

2017 drilling program at the Pontax spodumene pegmatite prospect with seven drill holes

completed for a total of 911.4 m drilled. Hole 975-17-014, drilled at -47 o to a vertical depth of

107 m, yielded the best intercept of the 2017 drilling with 21.39 m 1 grading 1.16% Li 2O at a

vertical depth of 48.2 m (from 68.90 m to 99.45 m; core length), including 5.22 m 1 grading

2.18% Li 2O (from 92.00 m to 99.45 m; core length), and 1.15 m 1 grading 3.18% Li 20 (from 68.9

m to 70.55 m; core length) (for additional details please refer to Stria new release dated

November 30, 2018, available on the Company’s Website at https://strialithium.com or at

www.sedar.com under Stria Lithium Inc.). The most recent drilling also builds on the results of

historic drilling and channel sampling programs carried out by previous owners of the Pontax

Lithium Property in 2009 and 2012. Historic holes (total: 864 m) intersected a swarm of lithium

bearing pegmatite dykes of an aggregated thickness of approximately 20 m, with the best

intercept found in hole 09-555-05 (0.97% Li 2O over 14.7 m reported as true thickness intervals

(from 36.0 m to 57.0 m; core length), including 1.43% Li 2O over 9.1 m (from 36.0 m to 49.0 m;

core length)2.

The average thickness of the Pontax spodumene bearing pegmatite swarm is estimated at 60 m

with the thickest zone lying along the northeast edge.

The Q1 2020 core drilling program at the Pontax Lithium Property was designed and operated by IOS

Services Géoscientifiques Inc. (IOS) of Saguenay, Québec, under the supervision of Table Jamésienne de

Concertation Minière (TJCM) of Chibougamau, Québec. The drilling was performed using a single

heliportable drill rig operated by Forages G4 Inc. of Rouyn-Noranda, Québec. All eleven core holes from

the drilling program were shipped from the field to IOS’s laboratory facilities in Saguenay, Québec in

preparation for detailed logging and sampling, as well as for core sample preparation (crushing and

grinding). The drill core was kept in a secured storage facility at IOS until mid-July 2021 at which time

core sampling worked commenced. In September 2021, IOS prepared 625 split core samples which were

then submitted to Activation Laboratories Ltd. (Actlabs) of Ancaster, Ontario, an ISO/IEC 17025:2005

certified facility, for multi-element analysis using ICP-OES spectral analysis after a sodium peroxide

fusion (code 8-Peroxide). Quality control, monitored by an IOS chemist, consists of 17% reference

materials including blank, duplicates and certified reference material (Oreas 148 and Oreas 149) for a

total of 103 QA\QC analysis.

On May 24, 2016, the Company reported that metallurgical testing of a 16.5 t bulk sample extracted

from the Pontax Spodumene Pegmatite occurrence achieved an initial assay result of 6.3% Li 2O from

spodumene concentrate with an 85% overall lithium recovery (refer to Stria news release dated May 24,

2016, available at http://strialithium.com or at www.sedar.com under Stria Lithium Inc.).
