DRILLING RESULTS ADVANCE AUTHIER PROJECT

Highlights

• 25 drillholes completed at Authier Lithium Project, Québec, with results including 9m @ 1.46% Li2O; lithium pegmatite mineralisation identified west of the resource and planned mining area

• 3 additional follow‐up holes completed to infill new mineralisation, with assay results pending

• Drilling builds confidence in quality and expansion potential of lithium resource base at Authier

• Sayona promoted to MSCI Global Small Cap Index as of 30 November, aiding global institutional investor awareness amid increasing North American lithium demand.

Emerging lithium producer Sayona Mining Limited (ASX:SYA; OTC:SYAXF) has completed a new drilling program at its Authier Lithium Project, with the results further strengthening the Company’s confidence in the quality of the lithium resource base at the Québec project.

A 25‐hole, 3,908m diamond drill program was undertaken with the results of the first 22 holes received. Drilling was conducted by Les Forages Pikogan, a member of the Algonquin Abitibiwinni community of Pikogan (First Nation Abitibiwinni), demonstrating Sayona’s commitment to the First Nations community.

Drillhole AL‐21‐14, located 250m west of the Authier resource and potential open pit, returned spodumene pegmatites assaying 9m @ 1.46% Li2O from 144.9m depth. Three additional holes have been completed to infill this new area of mineralisation, with assay results pending.

Welcoming the results, Sayona’s Managing Director, Brett Lynch said: “ We are encouraged by this latest round of drilling at Authier, which shows the potential for a further resource expansion at this key project.

“With additional exploration drilling planned across our Québec projects in the year ahead, we look forward to increasing our lithium asset base to support North America’s accelerating decarbonisation drive .”

The completed first stage 2021 drilling campaign at Authier totalled 25 drillholes for 3,990m, with drilling targeting five areas. Drill collars are displayed in the figure below and lithium intercepts detailed in Table 1.

At the Authier Footwall Dyke target, holes AL‐21‐001 through to AL‐21‐008 were drilled to test a footwall pegmatite underlying the resource area. These holes drilled through the resource envelope, intersecting the expected mineralisation within the main Authier dyke, but identified only a weakly developed or absent pegmatite in the targeted footwall position.

At the Authier North target, three holes comprising AL‐21‐010 through to AL‐21‐012 were completed and intersected pegmatite with a maximum mineralised intercept of 2.5m @ 0.66% Li2O from a depth of 83.1m at hole AL‐21‐011. Although low grade, this result is the first evidence of lithium mineralised pegmatite in this area of the lease, 200m north‐west of the resource area and requires further drilling to follow up.

Drilling of four of the planned holes to test the western extension of the north pegmatite was postponed to winter due to access problems related to wet conditions.

Hole AL‐21‐14, located 250m west of the Authier planned open pit, returned spodumene pegmatites assaying 9m @ 1.46% Li2O from 144m depth. Three additional holes, AL‐21‐023 to AL‐21‐025 were subsequently completed to infill this new area of mineralisation. Assays results for these infill holes are pending.

It was noted during logging that spodumene pegmatites were identified in two of the drill cores (see Table 1). The mineralisation in AL‐21‐014 is encouraging as it is the first mineralisation identified to the west of the Beaver Fault, a north‐east trending structure which segments and displaces the western resource area.

Once all results are received, further drilling will be planned to determine if consistent mineralisation can be identified for resource evaluation. A cross section of the drilling is displayed below.

To the east of the resource, holes AL‐21‐17 and AL‐21‐018 intersected a main pegmatite dyke up to 40m in thickness. These returned a best result of 3.4m @ 1.02% Li2O from a depth of 37.9m at hole AL‐21‐017, suggesting narrower mineralised pegmatites at shallow levels to the east of the planned open pit.

Holes AL‐21‐019 to AL‐21‐022 at the Far West and Far North targets did not intersect any significant mineralisation.

Additional work

Follow up drilling at Authier will be planned after the receipt of assay results, with priority work including:

• Updated Resource estimates;

• Updated definitive feasibility study; and

• Integration of the new data with Sayona´s Abitibi lithium hub.

Criteria	JORC Code explanation	Commentary
Sampling techniques	 Nature and quality of sampling (eg cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as down hole gamma sondes, or handheld XRF instruments, etc). These examples should not be taken as limiting the broad meaning of sampling.  Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used.  Aspects of the determination of mineralisation that are Material to the Public Report.  In cases where ‘industry standard’ work has been done this would be relatively simple (eg ‘reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30 g charge for fire assay’). In other cases more explanation may be required, such as where there is coarse gold that has inherent sampling problems. Unusual commodities or mineralisation types (eg submarine nodules) may warrant disclosure of detailed information.	 All holes reported in this program have been Diamond Core Drill holes (DDH)  Diamond core typical sample length is 1.0 metre starting 2 to 3 metres above and below of the contact of the pegmatite with the barren host rock. Sayona´s Phase 4 diamond drilling sampling in pegmatites includes lengths lower than 1.0 metres.  High to low grade lithium‐bearing mineralisation (spodumene) is visible during geological logging and sampling.  The core selected for sampling was split and samples of half core were dispatched to a certified commercial laboratory for preparation and analysis of lithium according to industry standard practices.  Sample preparation and assaying techniques are within industry standard and appropriate for this type of mineralisation.
Drilling techniques	 Drill type (eg core, reverse circulation, open‐hole hammer, rotary air blast, auger, Bangka, sonic, etc) and details (eg core diameter, triple or standard tube, depth of diamond tails, face‐sampling bit or other type,whether core	 Sayona´s phase 4 (2021) Diamond core drilling, core diameter size NQ.

Standard tube and bit.  Sayona´s phase 3 metallurgical drilling (2017), core diameter size PQ, standard tube and bit for 680 metres and 89.5 metres of HQ core diameter size.  Diamond core for phase 4 drilling (2021) was not oriented.  For Sayona´s phase 1 (2016) and phase 2 (2017) drilling campaigns, diamond core was oriented using a Reflex ACT III tool .  Core was not oriented for Sayona´s phase 3 drilling (2018) including metallurgical and condemnation drilling.  All core drilling before 2016 was NQ core diameter size, standard tube and bit,not oriented.
Drill sample recovery	 Method of recording and assessing core and chip sample recoveries and results assessed.  Measures taken to maximise sample recovery and ensure representative nature of the samples.  Whether a relationship exists between sample recovery and grade and whether sample bias may have occurred due to preferential loss/gain of fine/coarse material.	 Diamond drill hole core recoveries and RQD are logged. Measurements are taken systematically down hole between core blocks i.e. ~3 metre increments.  Core recovery has been above 98%.  Based on drilling method being diamond core and the near 100% core recovery the sampling is representative.  High competence of the core tends to preclude any potential issue of sampling bias
Logging	 Whether core and chip samples have been geologically and geotechnically logged to a level of detail to support appropriate Mineral Resource estimation, mining studies and metallurgical studies.  Whether logging is qualitative or quantitative in nature.

		 All PQ drill holes were drill in same drilling pad than both previous Sayona´s and historical holes showing a fair to good correlation between the metallurgical vs recent and historical drill holes when it was possible (for further information please refer to chapter 11 of Authier DFS report).  Primary data was recorded on laptop computers directly into standardised Excel logging templates with built in look‐up codes. This information is merged with the assay certificate data into a Sayona´s in‐house database  No adjustments to assay data have been undertaken..  For Verification of Sampling and Assaying details of all samples before 2016 please refer to Table 1 of ASX release “Authier Lithium Project JORC Resource Estimate” 7 July2016.
Location of data points	 Accuracy and quality of surveys used to locate drill holes (collar and down‐hole surveys), trenches, mine workings and other locations used in Mineral Resource estimation.  Specification of the grid system used.  Quality and adequacy of topographic control.	 Drill collars were surveyed by professional surveyor at the end of the 2021 drilling campaign similarly than Sayona´s phase 1, 2 and 3 drilling from 2016 to 2018.  Collar positions before 2016 have been surveyed and the survey values are recorded as the final coordinates and hole orientation in the database by an independent and qualified land surveyor.  Downhole surveys (dip and azimuth) for 2021 drilling were collected as single shot readings each 3 metres downhole up to the end of hole length using a Reflex tool.  Downhole surveys (dip and azimuth) were collected as multiple shot readings using a Gyro tool for deep holes AL‐17‐03 to AL‐17‐08; AL‐17‐13 to AL‐17‐14; AL‐17‐22, AL‐17‐26 and AL‐17‐28. Downhole surveys (dip and azimuth) were collected as multiple shot readings using a Reflex tool for deep holes AL‐17‐01 and AL‐17‐02. Azimuth readings were affected by rock magnetism therefore the reflex tool

		was replaced by gyro tool for deep holes. Downhole surveys we not done for shallow holes done in 2017. Holes AL‐17‐29 and AL‐17‐30 were not downhole surveyed because hole stability was compromised by faulting.  Downhole surveys (dip and azimuth) for 2018 drilling were collected as single shot readings using a Reflex tool. Measurements are made at the beginning (25 m below surface) and at the end of the hole length. An intermediate measure was done when drill hole length exceeded 150 m.  The grid system used is 1983 North American Datum (NAD83)  The level of topographic control offered by the collar survey is considered sufficient for the work undertaken at its current stage.
Data spacing and distribution	 Data spacing for reporting of Exploration Results.  Whether the data spacing and distribution is sufficient to establish the degree of geological and grade continuity appropriate for the Mineral Resource and Ore Reserve estimation procedure(s) and classifications applied.  Whether sample compositing has been applied.	 Drill holes were drilled perpendicular to the lithium mineralised pegmatite as shown on the attached plan.  Drill collars were sited to provide the best geological information possible to test the grade, strike and vertical extensions of mineralisation.  The data spacing at the main mineralised pegmatite is sufficient to estimate geological and grade continuity of observed mineralisation and therefore to produce a JORC compliant Mineral Resource estimate.  Sample compositing has not been applied.
Orientation of data in relation to geological structure	 Whether the orientation of sampling achieves unbiased sampling of possible structures and the extent to which this is known, considering the deposit type.  If the relationship between the drilling orientation and the orientation of key mineralised structures is considered to have introduced a sampling bias, this should be assessed and reported if material.	 Drilling grid orientation is perpendicular to the strike of the mineralisation determined by previous mapping and historical drilling.  No bias attributable to orientation of sampling upgrading of results has been identified.
