AUTHIER JORC ORE RESERVES EXPANDED

Sayona Mining Limited (ASX: SYA) ("Sayona" or the "Company") is pleased to announce an expanded Ore Reserve estimate based on the Optimised Pre-Feasibility Study (“PFS”) for the Authier lithium project in Quebec, Canada.

The PFS which is the subject of a separate announcement made today, demonstrates the technical and financial viability of constructing a simple, low-strip ratio, open-cut mining operation and processing facility producing spodumene concentrate. The positive PFS demonstrates the opportunity to create substantial long-term sustainable shareholder value at a manageable capital cost.

The positive PFS is considered sufficient to determine, in accordance with the JORC Code 2012, that a subset of the Measured and Indicated Mineral Resource (please see ASX announcement “Authier Lithium Project JORC Resource Updated”, 11 December 2017) be classified as Ore Reserves – see Table 1.

Table 1 – Authier JORC Ore Reserve Estimate (0.45% Li20 cut-off grade)

Category Tonnes (Mt) Grades (% Li20) Contained Li20 (t)
Proven Reserve 5.59 0.99 55,341
Probable Reserve 6.07 1.06 64,363
Total Reserves 11.66 1.03 120,098

The PFS demonstrates that a viable mining and processing operation, and the infrastructure to support this, are available to develop the project. The PFS takes into account all the modifying factors considered material to the development of the project and statement of Ore Reserves. The inputs into the economic and financial analysis were based on realistic assumptions of technical, engineering, operating and economic factors. The capital and operating cost estimates were obtained from reputable consulting groups at the appropriate level of confidence for the PFS.

JORC Mineral Resource Estimate

The Authier project has been subject to more than 27,000 metres of drilling. Between 2010 and 2012, Glen Eagle completed 8,990 metres of diamond drilling in 69 diamond drill holes of which 7,959 metres were drilled on the Authier deposit; 609 meters (5 DDH) were drilled on the Northwest and 422 metres on the south-southwest of the Property.

Sayona Mining has completed two phases of drilling including 49 drill holes for 8,084 metres, including 12 drill holes for 639 metres in Authier North pegmatite. All the holes completed by Sayona have used standard diamond drill holes (DDH), HQ or NQ core diameter size, using a standard tube and bit. The drilling programs have been subject to very robust QA/QC procedures.

An independent JORC Mineral Resource (2012) estimate for the Authier pegmatite deposit and Authier North pegmatite deposit is reported as per Table 2 (see ASX release, Authier JORC Mineral Resource Upgraded, 17 December 2017).

Table 2 – Authier + Authier North JORC Mineral Resources Estimate (0.45% Li20)
Category Tonnes (Mt) Grades (%Li20) Contained Li20 (t)
Measured 5.86 1.01 59,186
Indicated 10.19 1.03 104,957
Measured and Indicated 16.05 1.02 164,143
Inferred 2.30 0.99 22,796

The Mineral Resource estimates for the Authier and Authier North pegmatites are based on reported intercepts calculated using arithmetic averages, no top-cut, and a 0.45% Li2O cutoff grade. The estimation was based on an Inverse Distance Squared interpolation using Micromine software.

The parent block dimensions used were 3 metres x 3 metres x 3 metres with sub-blocks of 1.5 metres x 1.5 metres x 1.5 metres in accordance with the drill spacing and pegmatite body geometry. Three dimensional mineralized wireframes were used to domain the Li2O data using a 0.45 % Li2O cut-off for mineralised domain limits. Sample data was composited to 1.0m down hole lengths. Specific oriented ellipsoids search were used for grade interpolation at each pegmatite deposit.

The Measured Mineral Resource was defined within areas of close spaced diamond drilling of less than 35 metres by 35 metres, and where the continuity and predictability of the spodumene bearing pegmatite was high. The Indicated Mineral Resource was assigned to areas where drill hole spacing was less than 60 metres by 60 metres. The Inferred Mineral Resource was assigned to areas where drill hole spacing was greater than 60 metres by 60

JORC Ore Reserve Estimate

The revised ore reserve was derived from Sayona updated Pre-Feasibility Study on its 100% owned Authier lithium Project (see ASX release, Authier Optimised Pre-Feasibility Study Demonstrates Excellent Returns – Definitive Feasibility Study Underway, 17 December 2017). The revised Ore Reserve Estimate totals 11.66Mt at 1.03% Li2O (see Table 5 below).

Table 5 – Authier JORC Ore Reserve Estimate(0.45% Li20 cut-offgrade) Table 5 – Authier JORC Ore Reserve Estimate(0.45% Li20 cut-offgrade) Table 5 – Authier JORC Ore Reserve Estimate(0.45% Li20 cut-offgrade) Table 5 – Authier JORC Ore Reserve Estimate(0.45% Li20 cut-offgrade)

Proven Reserve 5.59 0.99 55,341
Probable Reserve 6.07 1.06 64,363
Total Reserves 11.66 1.03 120,098

This revised Ore Reserve estimate is in line with Industry best practice standards and reported according to the guidelines set by the JORC Code, 2012 Edition. Sayona had previously released an Ore Reserve estimate completed by SGS Geostat (see ASX release, Authier PFS, 22 February 2017).

A site visit was attended by the CP, Mr Jonathan Gagne, in June 2017. During this site visit the CP was able to meet with site representative, view the proposed infrastructure sites, the proposed pit location relative to the natural terrain, the surrounding general infrastructure and regional setting.

The resource model used as the basis for this Ore Reserves update was also compiled by Dr. Gustavo Delendatti, based on the latest available drilling information.

The Mineral Resource estimates for the Authier and Authier North pegmatites are based on reported intercepts calculated using arithmetic averages, no top-cut, and a 0.45% Li2O cutoff grade. The estimation was based on an Inverse Distance Squared interpolation using Micromine software. The parent block dimensions used were 3 metres x 3 metres x 3 metres with sub-blocks of 1.5 metres x 1.5 metres x 1.5 metres in accordance with the drill spacing and pegmatite body geometry.

Specific oriented ellipsoids search were used for grade interpolation at each pegmatite deposit. The Mineral Resources reported are inclusive of the Ore Reserves reported here.

The Ore Reserves are reported at a 0.45% Li2O cut-off, in line with the reporting of the Mineral Resources. This cut-off which is above the theoretical economic cut-off has been selected to increase the feed grade to the process facility.

Sayona carried out open pit optimisation utilising Whittle4X® software on the Measure and Indicated Resource material. Slope design criteria, mining dilution, ore loss and processing recoveries were applied in the pit optimisation process together with mining, processing, transport and sales cost estimates, and revenue projections to form the basis for pit designs and subsequent mining and processing schedules.

The outcome of the optimization was used to perform the detailed pit design. The design indicates a pit of ~1,00 metres in length (east-west), an average of 600 metres width (northsouth) and down to a final pit depth of 200 metres. The proposed open-pit is presented by the Figures below.

ASX Additional Information - Material Assumptions

Mineral Resource Estimate (Summary Information Required by Listing Rule 5.8.1)

Geology and Geological

The Property geology comprises intrusive units of the La Motte pluton to the north and Preissac pluton to the south, with volcano-sedimentary lithologies of the Malartic Group in the centre. The volcano-sedimentary stratigraphy is generally oriented east-west and ranges between 500 metres and 850 metres in thickness (north-south). The volcanic units comprise principally ultramafic (peridotitic) metavolcanic flows with less abundant basaltic metavolcanics. Several highly metamorphosed metasedimentary units described as hornblende-chlorite-biotite schists occur on the south-central portion of the Property generally in contact with the La Motte pluton to the north (Karpoff 1994).

The northern border of the Preissac pluton, composed of granodiorite and monzodiorite, runs east-west along the southern edge on the Property. To the north, muscovite monzogranitic units of the La Motte pluton cover the Property. Numerous small pegmatites generally composed of quartz monzonite are intruding the volcanic stratigraphy including the larger spodumene-bearing pegmatite which is the focus of the current Mineral Resource estimate.

Mineralisation is hosted within spodumene-bearing pegmatite intrusions. The Authier project hosts two separate mineralised pegmatite systems, including:

  • Authier Main - 1,100 metres long striking east-west, with an average thickness of 25 metres (ranging from 4 metres to 55 metres), dipping at 40 degrees to the north. The deposit outcrops in the eastern sector and then extends up to 10 metres under cover in the western sector. Drilling in the main Authier pegmatite resource totals 19,513 metres in 137 diamond holes. The deposit is open along strike to the west, east and at depth; and

  • Authier North - 300 metres long striking east-west, with an average thickness of 7 metres (ranging from 6 metres to 8 metres), dipping at 15 degrees to the north. Drilling in Authier North totals 13 holes for 670 metres. The deposit remains open and drilling is planned in the Phase 3 program underway to target extensions of the mineralisation.

The lithium mineralisation at the Authier project is related to multiple pulses of spodumene bearing quartz-feldspar pegmatite. Higher lithium grades are related with high concentrations of mid-to-coarse spodumene crystals (up to 4 cm long) in a mid-to-coarse grained pegmatite facies.

Drilling Techniques and Hole Spacing

The Authier project has been subject to more than 27,000 metres of drilling. Between 2010 and 2012, Glen Eagle completed 8,990 metres of diamond drilling in 69 diamond drill holes


___ Page 5 of 48

==> picture [595 x 52] intentionally omitted <==

==> picture [595 x 52] intentionally omitted <==

of which 7,959 metres were drilled on the Authier deposit; 609 meters (5 DDH) were drilled on the Northwest and 422 metres on the south-southwest of the Property.

Sayona Mining has completed two phases of drilling including 49 drill holes for 8,084 metres, including 12 drill holes for 639 metres in Authier North pegmatite. All the holes completed by Sayona have used standard diamond drill holes (DDH), HQ or NQ core diameter size, using a standard tube and bit. The drilling programs have been subject to very robust QA/QC procedures.

The core was oriented using a Reflex ACT III tool. All core drilling before 2016 was NQ core diameter size, standard tube and bit, not oriented.

Holes were typically drilled perpendicular to the strike of the mineralised pegmatite to provide high confidence in the grade, strike and vertical extensions of the mineralisation.

DDH holes were drilled on nominally grid patterns ranging from 30 metres x 30 metres up to 50 metres x 50 metres. The grid pattern is considered an adequate spacing for establishing geological and grade continuity along strike and down dip and therefore appropriate for defining Measured, Indicated and Inferred Resource categories within the resource area.

- Sampling and Sub Sampling

Drill core HQ diameter samples cut to two halves with one half placed in a new plastic bag along with the sample tag sent for analysis. The other half was replaced in the core box with the second sample tag for reference.

Sampling boundaries are based in geological contacts of spodumene-bearing pegmatite with host rock.

In general, at least two host rock samples were collected each side of the contacts with the mineralised pegmatite.

Sample preparation of the drill core samples collected during the drilling programs is assayed at the SGS Canada Inc laboratory (“SGS”) facilities in Sudbury, Ontario follows industry best practice, involving oven drying, crushing and pulverising onsite to respect the specifications of the analytical protocol, and then are shipped to SGS Mineral Services laboratories in Lakefield, Ontario, for analysis.

Sample sizes are considered appropriate with regards to the grain size of the sampled material.

For sample preparation and sub-sampling techniques, and details of drill core samples before 2016, please refer to Table 1 of ASX release “Authier JORC Resource Estimate”, 7 July 2016.

Sample Analysis Method

Assaying of all 2016 and 2017 drilling sample received at SGS were processed according to the following procedure at the SGS preparation facilities in Sudbury, Ontario. All samples are


___ Page 6 of 48

==> picture [595 x 52] intentionally omitted <==

==> picture [595 x 52] intentionally omitted <==

inspected and compared to the chain of custody (“COC”) and logged into the SGS laboratory management system, then weighted and dried. Sample material is crushed to 75% passing 10 mesh (2mm), split to obtain a 250g sub-sample which is then pulverised to 85% passing 200 mesh (75 microns).

The analyses of all 2016 and 2017 drilling sample were conducted at the SGS laboratory located in Lakefield, Ontario, which is an accredited laboratory under ISO/IEC 17025 standards accredited by the Standards Council of Canada.

The analytical protocol used at SGS Lakefield is the GE ICP90A 29 element analysis-sodium peroxide fusion, which involves the complete dissolution of the sample in molten flux for ICPAES analysis. The detection limits for lithium are 10 ppm (lower) and 10,000 ppm (upper).

No geophysical or handheld tools were used.

Quality control protocols (“QA/QC”) involve a review of laboratory supplied internal QA/QC and in-house controls, consisting of the insertion of in-house reference standards (high and low grade, prepared with material of the project and certified by lab round-robin), and samples of “barren” material (“blanks”) on a systematic basis, with the samples shipped to SGS.

For Quality of Assay Data and Laboratory Tests of all samples before 2016, please refer to Table 1 of ASX release “Authier JORC Resource Estimate”, 7 July 2016.

Mineral Tenement and Land Tenure Status

The Property consists in one block of map designated claim cells located at the border between the La Motte Township and the Preissac Township, totalling 20 claims covering 653 hectares. The Property extends 3.4km in the east-west direction and 3.1km north-south. Approximately 75% of the mineral resources are present inside the 3 claims (CDC 2183455, 2194819 and 2116145) and the rest in inside claims 2183454 and 2187652

All tenements covering the deposit are in good standing and there are no known impediments to obtaining a license to operate.

Estimation Methodology

The Resource Estimate was based on an Inverse Distance Power (“IDP”) interpolation with an oriented “ellipsoid” search using Micromine software. The parent block dimensions used were 5 metres x 5 metres x 5 metres with sub-blocks of 2.5 metres x 2.5 metres x 2.5 metres in accordance with the drill spacing and pegmatite body geometry. The Mineral Resource estimate was undertaken using reported intercepts calculated using arithmetic averages, no top-cut, and a 0.5% Li2O cut-off grade.

Three dimensional mineralised wireframes were used to domain the Li2O data using a 0.5% Li2O cut-off for mineralised domain limits. Sample data was composited to 1.0 metre down hole lengths. The Li2O values in intervals with assays below the detection limit were set to half of detection limit. Internal low grade samples up to three consecutive metres (lower than


___ Page 7 of 48

==> picture [595 x 52] intentionally omitted <==

==> picture [595 x 52] intentionally omitted <==

0.5% Li2O) were included in the mineralised wireframe as internal dilution. Based on the statistical analysis there is no need for grade capping. The search ellipsoid was orientated to the average strike, plunge, and dip of pegmatite body. Three passes were used. The first pass had a range of 30 metres, with a minimum of 5 composites. For the second pass, the range was 50 metres, with a minimum of 4 composites. For the third pass, the range was extended to 90 metres, with a minimum of 1 composites. A maximum of 20 composites were used for all three passes.

The block model size used in the Mineral Resource estimate was based on drill sample spacing and pegmatite body geometry. Selective mining units were not modelled.

Resource Classification

The Authier Lithium Mineral Resource was classified as a Measured, Indicated and Inferred, based on drilling density, sample spacing and geological/mineralisation continuity in accordance with the Australasian Code for the Reporting of Exploration Results, Mineral Resources and Ore Reserves (JORC 2012).

The Measured Mineral Resource was defined within areas of close spaced diamond drilling of less than 35 metres by 35 metres, and where the continuity and predictability of the spodumene bearing pegmatite was good. The Indicated Mineral Resource was assigned to areas where drill hole spacing was less than 50 metres by 50 metres. The Inferred Mineral Resource was assigned to areas where drill hole spacing was greater than 50 metres by 50 metres generally in the edges of the known mineralisation, mostly in down-dip extensions beyond the last drill holes in each section.

The input data is comprehensive in its coverage of the mineralisation and does not favour or misrepresent in-situ mineralisation. The definition of mineralised zones is based on high level geological understanding producing a robust model of mineralised domains. This model has been confirmed by infill drilling which supported the interpretation. Validation of the block model shows good correlation of the input data to the estimated grades.

The Mineral Resource estimates appropriately reflect the view of the Competent Person.

Cut-off Grade

The Mineral Resource has been reported at a 0.45% Li2O cut-off. The cut-off grade is based on the detailed economic analysis performed in the Pre-Feasibility Study (see ASX release, AUTHIER OPTIMISED PRE-FEASIBILITY STUDY DEMONSTRATES EXCELLENT RETURNS - DEFINITIVE FEASIBILITY STUDY UNDERWAY, 11 December 2017).

Mining and Metallurgical Methods and Parameters and Other Modifying Factors

Taking into account the geometry and the depth of the mineralised zone, the Authier Lithium deposit will be mined using open-pit mining methods.

Based on the metallurgical test work conducted at Authier, a 6% Li2O concentrate can be produced using conventional flotation technology suitable for a pegmatite orebody. The


___ Page 8 of 48

==> picture [595 x 52] intentionally omitted <==

processing plant comprised seven key areas including three-stage crushing, grinding, micaflotation, spodumene flotation, magnetic separation, concentrate dewatering and drying, and tailings filtering.

No dilution or ore loss factors have been taken into account in the JORC Resource.

Notes to Accompany Mineral Resources Estimate Table:

  • Assays for the updated 2017 Resource Estimate at the Authier project were derived from 118 Diamond Core Holes for 16,048 metres. This dataset includes, 18 diamond core holes for 3,967 metres conducted by Sayona in 2016, at a HQ core size. Drilling before Sayona was NQ core size.

  • Drilling density at Authier ranges from 30 metres x 30 metres up to 50 metres x 50 metres, with the grid pattern extending over the majority of the deposit area.

  • Mineralisation wireframes were delineated based on a nominal 0.45% Li2O lower cutoff at start and end of each mineralised interval.

  • A resource block model was constructed with parent block dimensions of 5 metres x 5 metres x 5 metres with sub-blocks of 2.5 metres x 2.5 metres x 2.5 metres in accordance with the drill spacing and geological models, reflecting pegmatite body geometry and wall rock lithology.

  • The Resource Estimate was based on an Inverse Distance Power (IDP) interpolation with an oriented “ellipsoid” search using Micromine software. No top cuts were applied.

  • The Authier Lithium Mineral Resource was classified as a Measured, Indicated and Inferred, based on drilling density, sample spacing and geological/mineralisation continuity in accordance with the Australasian Code for the Reporting of Exploration Results, Mineral Resources and Ore Reserves (JORC 2012).

  • The Measured Mineral Resource was defined within areas of close spaced diamond drilling of less than 35 metres by 35 metres, and where the continuity and predictability of the spodumene bearing pegmatite was good. The Indicated Mineral Resource was assigned to areas where drill hole spacing was less than 50 metres by 50 metres. The Inferred Mineral Resource was assigned to areas where drill hole spacing was greater than 50 metres by 50 metres, generally in the edges of the known mineralisation and mostly in down-dip extensions beyond the last drill holes in each section.

  • Specific gravity (“SG”) measurements were conducted by SGS on 38 mineralised core samples collected from drill holes AL-10-01 and AL-10-11. The measurements were performed using the water displacement method (weight in air/volume of water displaced) on representative half core piece, returning average SG value of 2.71 t/m3.

  • The Resource Estimate was checked against previous estimates and internally against geological and mineralisation models.

  • Future mining at Authier deposit is planned to be open cut using drill-blast, standard excavator and truck mining methods. No other assumptions on mining methodology have been made.

Ore Reserve Estimate (Summary Information Required by Listing Rule 5.9.1)

Material Assumptions

The material assumptions which support the Ore Reserve Estimate, the Production Targets and the forecast financial information derived from the Production Targets are disclosed in the body of the announcement and outlined in the ASX Additional Information – Material Assumptions section, with the exception of commercially sensitive information.

The mining costs used by Sayona in the calculation of the Ore Reserve Estimate were based on the physicals derived from the Life-of-Mine (“LOM”) schedule developed by Sayona, calculated mining costs, current fuel prices and an owner cost component developed by Sayona.

Criteria Used for the Classification of Ore Reserves

The Ore Reserves are reported at a 0.45% Li2O cut-off, in line with the reporting of the Mineral Resources. This cut-off which is above the theoretical economic cut-off has been selected to increase the feed grade to the process facility.

Sayona carried out open pit optimisation utilising Whittle4X® software on the Measure and Indicated Resource material. Slope design criteria, mining dilution, ore loss and processing recoveries were applied in the pit optimisation process together with mining, processing, transport and sales cost estimates, and revenue projections to form the basis for pit designs and subsequent mining and processing schedules.

The outcome of the optimization was used to perform the detailed pit design. The design indicates a pit of ~1,000 metres in length (east-west), an average of 600 metres width (northsouth) and down to a final pit depth of 200 metres.

Mining Method and Assumptions

A conventional open pit mine method was chosen as the basis of the PFS. Ore is exposed at surface requiring minimal pre-stripping and pre-production mining activities. Mining dilution and ore loss were applied to the in-pit resource to estimate the Ore Reserves.

Major modifying factors include: 0.45% Li2O cut-off grade; ore production rate of 700Mtpa; 82% recovery of Li2O as 6% Spodumene concentrate; Gross price of CAD$614/t Conc.; overall ore based cost 32.94 CAD/t (processing, G&A and transport); and an average mining cost of 3.14 CAD/t.

Processing Method and Assumptions

Based on the results of metallurgical testing programs at SGS Lakefield, Wave International have designed a concentrator plant to process 2,000 tonnes per day or approximately 700,000 tpa of ore feed using conventional flotation technology suitable for a pegmatite orebody. The processing plant comprised seven key areas including three-stage crushing, grinding, mica-flotation, spodumene flotation, magnetic separation, concentrate

==> picture [595 x 52] intentionally omitted <==

dewatering and drying, and tailings filtering. The plant will produce a 6% Li20 concentrate suitable for sale to lithium carbonate conversion plants that supply feed-stock to the lithium battery manufacturers. The plant will be located near the open-pit and operate 365 days per year at 95% availability.

The plant will produce a LOM average of 96,000 tonnes of 6% Li20 concentrate suitable for sale to lithium carbonate conversion plants that supply feed-stock to the lithium battery manufacturers.

Cut-off Grades

Using the economic parameters used for the pit optimization exercise, the resulting open pit cut-off grade was initially calculated at 0.35% Li2O. Preliminary life-of-mine exercises concluded that it would be economically beneficial to use a higher cut-off grade than what resulted from the optimization parameters. A cut-off of 0.45% Li2O was selected for the base case of this pre-feasibility study. Using such a cut-off improve the overall economics and avoid sending marginal material on which we don't make much profit and potentially negatively affects the concentrate grade due to its low Li2O content. The cut-off grade is calculated by the total ore based cost divided by the net commodity value.

Estimation Methodology

Please refer to the discussion on this item as set out in the previous section which details the summary information required by LR 5.8.1 for Mineral Resource estimates.

Infrastructure

The Authier project is situated approximately 500 kilometres north-west of Montreal. The established mining support city of Val d’Or is situated 45 kilometres south-east of the project, and the city of Amos is 20 kilometres to the north. The project is readily accessible from Val d’Or or Amos by the national highway and a high-quality rural road network five kilometres east of the project site.

Water requirements for processing can be serviced from the total implied water resources within the mine area. Power will be accessed 5 kilometres to the east of the project site via an electricity grid supplied by low-cost, hydro-electric power. Product will be shipped via Port of Montreal.

Economic

The economic analysis is based on cash flows driven by the production schedule. The cash flow projection includes:

  • Initial and sustaining capital estimates;

  • Mining, processing and concentrate logistics costs to the customer based on FOB Port of Montreal pricing;

  • Revenue estimates based on concentrate pricing adjusted for fees, charges and royalties;


___ Page 11 of 48

==> picture [595 x 52] intentionally omitted <==

==> picture [595 x 52] intentionally omitted <==

  • Closure costs; and

  • An 8% real discount factor.

Spodumene pricing was based on forecasts from a number leading lithium industry research organisations.

Other factors, include:

  1. The average head grade of the Ore has been estimated at 1.03% Li2O over the 17 years of processing operation;

  2. Processing recoveries of 82% of Li2O as 6% spodumene concentrate;

  3. Spodumene selling price of US$614/t of concentrate at a discount rate of 8%;

  4. An exchange rate of 0.76 USD per CAD was used to convert the USD market price projections into Canadian currency;

  5. Transport and port charges of 60.00 CAD/t

  6. Corporate tax - The current Canadian tax system applicable to Mineral Resource Income is used to assess the Project’s annual tax liabilities. This consists of federal and provincial corporate taxes as well as provincial mining taxes. The federal and provincial corporate tax rates currently applicable over the Project’s operating life are 15.0% and 11.9% of taxable income, respectively. The marginal tax rates applicable under the recently adopted mining tax regulations in Quebec (originally proposed as Bill 55, December 2013) are 16%, 22% and 28% of taxable income and depend on the profit margin. The analysis for the PFS is done on a pre-tax basis;

  7. Inflation – All the forecasts within the financial analysis are on a real basis i.e. with no inflation adjustments; and

  8. Royalties – The Quebec Government does not impose any royalties on mineral production. However, Authier is subject to a number of vendor royalty payments and a 2.44% NSR royalty was assumed in the Ore Reserve Estimate and financial modeling undertaken for the PFS.

Other Non-Mining Modifying Factors

No material naturally occurring risks have been identified. The Authier Lithium Property comprises one block of 20 map designated claim cells covering 653 hectares that are properly granted and in good standing, and have sufficient area for open pit, plant and other infrastructure. Surface rights for all the claims composing the Property are owned by the government. There is no reason to believe that the Company will not be able to secure the surface rights to construct the infrastructure related to a potential mining operation, including tailings storage and waste disposal areas, and processing plants. There are no apparent impediments to obtaining all government approvals required for the project. Sayona is conducting exploration work under valid intervention permits delivered by the Quebec Government, and there are no known environmental liabilities pertaining to the Property. Some of the claims containing Mineral Resources are subject to mining royalties. Road access has been granted.

Lithium concentrate produced from Authier will be classed as Chemical Grade specification, principally due to its high iron content. The principal markets for Chemical Grade concentrates are battery, lubricants, aluminum smelting and pharmaceuticals applications. The lithium market is currently experiencing a major demand shift driven by the increasingly critical role of the lithium-ion battery technology for storage applications in the automotive, consumer electronics and electricity storage/distribution sectors. For the Authier PFS, Deutsche Bank forecasts from a comprehensive lithium study prepared on the 9th May 2016 have been used.

The Company is exploring a number of options for selling high-quality spodumene concentrate that will be produced from a future operation at Authier. This includes direct sales of concentrate to converters that produce lithium products suitable for the global battery markets.

The Company has had discussions with companies that have or are proposing to build lithium carbonate plants in Canada, and has received strong interest for the supply of new concentrates to these facilities. In addition, in early November 2016, the Company attended a global lithium conference in China and held a number of discussions with interested parties seeking to establish long-term spodumene sales contracts. The Company is also assessing the option of processing and producing a lithium carbonate product through an integrated downstream processing facility at Authier.

A Community Relations Program is being developed to approach and engage local stakeholders. This program will include information sessions and consultations with municipalities, landowners, First Nation community, non-governmental environmental organizations and recreational associations. Consultation and community engagement efforts that will be deployed throughout the project development and operating phases.

JORC CODE, 2012 EDITION – TABLE 1

Section 1 Sampling Techniques and Data

(Criteria in this section apply to all succeeding sections.)

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 ofdetailedinformation.
 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.
 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 is oriented and if so, by what
method, etc).
 Core drilling, core diameter size
HQ. Standard tube and bit.
 Core was oriented using a Reflex
ACT III tool.
 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.
 Diamond drill hole core recoveries
and RQD are logged.
Measurements are taken
systematically down hole between
core blocks i.e. ~3 metre
increments.

==> picture [595 x 52] intentionally omitted <==

 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.
 Core recovery has been above
99%.
 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 ofsampling 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. Core (or
costean, channel, etc) photography.
 The total length and percentage of
the relevant intersections logged.
 Geological logging, RQD
measurements, alpha and beta
angles of structures as core
orientation using reflex tool
completed for all holes done in
2016 by Sayona.
 Geological logging of main
characteristics such as rock type,
spodumene abundance, mica
abundance, etc has occurred in
summary and detail at the
pegmatite intervals and
surrounding host rock.
 Detailed geotechnical logging
including RQD, orientation data
(alpha and beta angles) for
structures (faults, fractures, etc),
point load tests (1 each 10 metres
average) has also been
undertaken.
 The geological and geotechnical
logging is at an appropriate level
for the stage of development
drilling being undertaken.
 The logging of the geological
features was predominately
qualitative. Parameters such as
spodumene abundance are visual
estimates by the logging geologist.
 Core is photographed after metre
marks and sample intervals have
been clearly marked on the core.
The core was photographed dry
and wet. The core boxes were
identified with Box Number, Hole
ID, From and To using aluminum
tags.
 The entire target mineralisation
type core (spodumene pegmatite)
and surrounding barren host rock
has been logged, sampled and
assayed. Thefootwallandhanging

second sample tag for reference.
 Sampling boundaries are based in
geological contacts of
spodumene-bearing pegmatite
with host rock.
 In general at least two host rock
sample were collected each side
from the contacts with the
mineralised pegmatite.
 Sample preparation of drill core
samples collected during the 2016
drilling program completed at the
SGS Canada Inc laboratory
(“SGS”) facilities in Sudbury,
Ontario follows industry best
practice, involving oven drying,

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

Drill hole
Information
 A summary of all information
material to the understanding of the
exploration results including a
tabulation of the following
information for all Material drill holes:

collar
 elevation or RL (Reduced Level –
elevation above sea level in metres)
of the drill hole collar
 dip and azimuth of the hole
 down hole length and interception
depth
 hole length.
 If the exclusion of this information is
justified on the basis that the
information is not Material and this
exclusion does not detract from the
understanding of the report, the
Competent Person should clearly
explain why thisis the case.
 In 2017, Sayona drilled 4,117 metres
in 31 diamond holes. The aim of the
program was to extend the zones of
mineralisation along strike and
depth, improve the resource
categories and explore the Authier
north pegmatite, discovered during
2016 Stage 01 drilling by Sayona.
 Drill hole details are reported in the
body of this announcement as
TABLE 6.
Data
aggregation
methods
 In reporting Exploration Results,
weighting averaging techniques,
maximum and/or minimum grade
truncations (eg cutting of high
grades) and cut-off grades are
usually Material and should be
stated.
 Where aggregate intercepts
incorporate short lengths of high
grade results and longer lengths of
low grade results, the procedure
used for such aggregation should be
stated and some typical examples
of such aggregations should be
shown in detail.
 The assumptions used for any
reporting of metal equivalent values
should be clearly stated.
 No weight averaging or high-grade
cut has been applied to any of the
sample assay results.
 Reported intercepts have been
calculated as arithmetic averages
using a 0.45 % Li20 lower cutoff
grade, as described in the body text
of this release.
 The majority of the lithium assay
results show a simple normal
population and it is not believed the
reporting of intercepts is skewed by
the inclusion of high and low grade
results.
 Metal equivalent values have not
been reported.
Relationship
between
mineralisation
widths and
 These relationships are particularly
important in the reporting of
Exploration Results.
 If the geometry of the mineralisation

reported.
 If it is not known and only the down
hole lengths are reported, there
should be a clear statement to this
effect (eg ‘down hole length, true
width not known’).
width is approximately 90% of drilling
width.
Diagrams  Appropriate maps and sections
(with scales) and tabulations of
intercepts should be included for
any significant discovery being
reported These should include, but
not be limited to a plan view of drill
hole collar locations and
appropriate sectional views.
 A Collar Plan and typical cross-
sections are presented in the body
of this report. Drill hole details are
reported in the body of this
announcement as TABLE 6.
Balanced
reporting
 Where comprehensive reporting of
all Exploration Results is not
practicable, representative
reporting of both low and high
grades and/or widths should be
practiced to avoid misleading
reporting of Exploration Results.
 The reporting is considered to be
balanced.
Other
substantive
exploration
data
 Other exploration data, if
meaningful and material, should be
reported including (but not limited
to): geological observations;
geophysical survey results;
geochemical survey results; bulk
samples – size and method of
treatment; metallurgical test results;
bulk density, groundwater,
geotechnical and rock

Author reviewed drill hole collars,
surface geology and mineralised
diamond core intervals stored at
project field facilities and it was
concluded that these were being
conducted to bestindustry practice
Geological
interpretation
 Confidence in (or conversely, the
uncertainty of ) the geological
interpretation of the mineral deposit.
 Nature of the data used and of any
assumptions made.
 The effect, if any, of alternative
interpretations on Mineral Resource
estimation.
 The use of geology in guiding and
controlling Mineral Resource
estimation.
 The factors affecting continuity both
of grade and geology.
 The confidence in the geological
interpretation at Authier Lithium
deposit is considered to be good
and is based on the drilling density
and well known geological
features.
 Drill hole logging by Glen Eagle and
Sayona’s geologists, through direct
observation of drill core samples
have been used to interpret the
geological setting.
 The continuity of the main
mineralised body is clearly observed
by Li2O grades correlated with
spodumene rich pegmatite within
the drill holes. The nature and
continuity along strike of the lithium
mineralisation would indicate that
alternate interpretations would
have little impact on the overall
Mineral Resource estimation.
 The mineralisation is related to a
pegmatite intrusive with multiple
phases of spodumene
mineralisation.
Dimensions  The extent and variability of the
Mineral Resource expressed as
length (along strike or otherwise),
plan width, and depth below
surface to the upper and lower limits
of the Mineral Resource.
 The Authier Lithium Mineral
Resource includes two pegmatites
striking east-west and dipping to the
north: Authier Main and Authier
North.
 Authier Main area extends over a
strike length of 1,100 m, has an
average width of 25 m, typically
extends down just below 200
metres, and dips 40 - 50 degrees to
the north.

lengths. The Li2O values in intervals
with assays below detection limit
were set to half of detection limit.
 Based on the statistical analysis
there is no need for grade capping.
 An orientated ‘ellipsoid’ search was
used to select data and was based
on the observed lens geometry. The
search ellipsoid was orientated to
the average strike, plunge, and dip
of pegmatite body.
 Three passes were used. The first
pass had a range of 35 m, with a
minimum of 4 samples. For the
second pass, the range was 65 m,
with a minimum of 3 samples. For
the third pass, the range was
extended to 120 m, with a minimum
of 1 sample. A maximum of 20
samples was used for all three
passes.
 The parent block dimensions used
were 3 m x 3 m x 3 m with sub-
blocks of 1.5 m x 1.5 m x 1.5 m. The
parent block size was selected on
the basis of being approximately
25% of the average drill hole
spacing.

It is always necessary as part of the
process of determining reasonable
prospects for eventual economic
extraction to consider potential
mining methods, but the
assumptions made regarding mining
methods and parameters when
estimating Mineral Resources may
not always be rigorous. Where this is
the case, this should be reported

be mined using open-pit mining
methods.
 No dilution or ore loss factors have
been taken into account in the
JORC Resource.
Metallurgical
factors or
assumptions
 The basis for assumptions or
predictions regarding metallurgical
amenability. It is always necessary as
part of the process of determining
reasonable prospects for eventual
economic extraction to consider
potential metallurgical methods, but
the assumptions regarding
metallurgical treatment processes
and parameters made when
reporting Mineral Resources may not
always be rigorous. Where this is the
case, this should be reported with
an explanation of the basis of the
metallurgical assumptions made.
 Metallurgical testing at Authier
Lithium deposit was conducted in
four stages; 1999, 2012, 2016 and
2017.
 In 1999, Bumigeme Inc, processing
consultants, conducted
metallurgical testing on a 40 tonne
bulk sample and produced
concentrate grades between 5.78%
and 5.89% Li20 at metallurgical
recoveries between 67.52% and
70.19%, with an average head
assay of 1.14% Li20. At an average
head grade of 1.35% Li20, test work
demonstrated a recovery of 75%
and a concentrate grade of 5.96%
Li20.
 In 2012, Glen Eagle completing
testing on a 270 kilogram sample
from drill core. Very attractive results
including an 85% metallurgical
recovery to a 6.44% Li20
concentrate was achieved with
three stages of cleaning.
 In 2016, Sayona completed a
metallurgical testing program using
core from twenty-three historical
diamond holes totaling 430
kilograms, representing the entire
deposit geometry (including the
anticipated 5% mine ore dilution), at
SGS Lakefield in Canada.
Concentrate grades varied from
5.38% to 6.05% Li20 at recoveries
between 71.2% and 78.6%.
Mineralogical (using QEMSCAN)
analysis of the final concentrates
demonstrated that the ore dilution

___ Page 30 of 48

==> picture [595 x 52] intentionally omitted <==

had a negative impact on flotation
performance.
 In 2017, two new representative
samples were prepared and
flotation testing undertaken using
different test conditions including
diluted and un-diluted, and with site
water. The program demonstrated
the ability to produce concentrate
grades over 6% at metallurgical
recoveries over 80% Li20.
Environmental
factors or
assumptions
 Assumptions made regarding
possible waste and process residue
disposal options. It is always
necessary as part of the process of
determining reasonable prospects
for eventual economic extraction to
consider the potential
environmental impacts of the mining
and processing operation. While at
this stage the determination of
potential environmental impacts,
particularly for a greenfields project,
may not always be well advanced,
the status of early consideration of
these potential environmental
impacts should be reported. Where
these aspects have not been
considered this should be reported
with an explanation of the
environmental assumptions made.
 An Environmental Baseline Studies
(EBS) have been completed in
October 2017 for the Authier project
and results will be available over the
following months. However,
previous studies were conducted
during 2012 by Dessau and GFE and
didn’t return environmental issues.
Activities by DESSAU and GFE were
performed to determine constraints
linked to water and sediments
quality and to environmental
(physical, biological, human)
impact.
 According to public databases and
from field inventories lead during
this study by Dessau and GFE, no
endangered species or habitats
were found
 A plan regarding proposed waste
and process residue facilities
management and disposal has
been prepared and included in the
PFS report.
 Sayona Mining conducted a
geochemical characterization
study of ore, waste rock and tailings
samples. The program allows the
classification of waste rock and
tailings according to provincial
authority’s regulations standard for
acid mine drainage and
leachability, and identify any
chemical that could potentially
affect the surface or groundwater
quality. No evidence of sulfides has
been observed in the ore or in the
waste rock.
 A rehabilitation and closure plan is
arequirement underthe“Loisur les

mines”. It must be approved before
the mining lease is issued, and a
financial guarantee to fully
implement the plan must be
provided in three payments in the
first two years following the
approval of the plan.
 A Community Relations Program is
being developed to approach and
engage local stakeholders. This
program will include information
sessions and consultations with
municipalities, landowners, First
Nation community, non-
governmental environmental
organizations and recreational
associations.
Bulk density  Whether assumed or determined. If
assumed, the basis for the
assumptions. If determined, the
method used, whether wet or dry,
the frequency of the measurements,
the nature, size and
representativeness of the samples.
 The bulk density for bulk material
must have been measured by
methods that adequately account
for void spaces (vugs, porosity, etc),
moisture and differences between
rock and alteration zones within the
deposit.
 Discuss assumptions for bulk density
estimates used in the evaluation
process of the different materials.
 As part of the 2010 independent
data verification program, SGS
Geostat conducted specific gravity
(“SG”) measurements on 38
mineralised core samples collected
from drill holes AL-10-01 and AL-10-
11. The measurements were
performed using the water
displacement method (weight in
air/volume of water displaced) on
representative half core pieces
weighting between 0.67 kg and
1.33 kg with an average of 1.15 kg,
results average SG value of 2.71
t/m3.
 In 2017, an independent data
verification program performed by
ALS Val d’Or was conducted to
assess specific gravity (“SG”)
measurements on waste material
using 14 mineralized core samples.
The measurements were performed
using the water displacement
method (weight in air/volume of
water displaced) on representative
half core and resulted in an
average SG value of 2.90 t/m3.
Classification  The basis for the classification of the
Mineral Resources into varying
confidence categories.
 Whether appropriate account has
been taken of all relevant factors (ie
relative confidence in
tonnage/grade estimations,
 Mineral Resource have been
classified in accordance with the
Australasian Code for the Reporting
of Exploration Results, Mineral
Resources and Ore Reserves (JORC,
2012).

reliability of input data, confidence
in continuity of geology and metal
values, quality, quantity and
distribution of the data).
 Whether the result appropriately
reflects the Competent Person’s
view of the deposit.
 The Authier Lithium Mineral
Resource was classified as
Measured, Indicated and Inferred
Mineral resource based on drilling
density, sample spacing and
geological / mineralisation
continuity.
 The Measured Mineral Resource
was defined within areas of close
spaced diamond drilling of less than
35m by 35m, and where the
continuity and predictability of the
spodumene bearing pegmatite was
good. The Indicated Mineral
Resource was assigned to areas
where drill hole spacing was less
than 60m by 60m. The Inferred
mineral resource was assigned to
areas where drill hole spacing was
greater than 60m by 60m generally
in the edges of the known
mineralisation mostly in down-dip
extensions beyond the last drill holes
in each section.
 The input data is comprehensive in
its coverage of the mineralisation
and does not favour or misrepresent
in-situ mineralisation. The definition
of mineralised zones is based on
high level geological understanding
producing a robust model of
mineralised domains. This model has
been confirmed by infill drilling
which supported the interpretation.
Validation of the block model shows
good correlation of the input data
to the estimated grades.
 The Mineral Resource estimates
appropriately reflect the view of the
Competent Person.
Audits or
reviews
 The results of any audits or reviews of
Mineral Resource estimates.
 Prior to Sayona’s acquisition of
Authier, Internal audits have been
completed by SGS Geostats at the
request of Glen Eagle Resource Inc
in a NI43-101 Technical Report,
Preliminary Economic Assessment,
22 January 2013
 No external audits have been
undertaken on the Sayona JORC
Resource estimate. However, SGS in
Canadawho are assistingwiththe

preparation of the 2016 Authier Pre-
Feasibility Study has reviewed the
datafor mine planning purposes.
Discussion of
relative
accuracy/
confidence
 Where appropriate a statement of
the relative accuracy and
confidence level in the Mineral
Resource estimate using an
approach or procedure deemed
appropriate by the Competent
Person. For example, the application
of statistical or geostatistical
procedures to quantify the relative
accuracy of the resource within
stated confidence limits, or, if such
an approach is not deemed
appropriate, a qualitative discussion
of the factors that could affect the
relative accuracy and confidence
of the estimate.
 The statement should specify
whether it relates to global or local
estimates, and, if local, state the
relevant tonnages, which should be
relevant to technical and economic
evaluation. Documentation should
include assumptions made and the
procedures used.
 These statements of relative
accuracy and confidence of the
estimate should be compared with
productiondata,where available.
 The pegmatite geometry and
continuity has been adequately
interpreted to reflect the applied
level of Measured, Indicated and
Inferred Mineral Resource. The data
quality is good and the drill holes
have detailed logs produced by
qualified geologists. All diamond
core obtained by Glen Eagle and
Sayona drilling campaigns are
properly stored and mineralised
intervals can be reviewed when
required. Recognized laboratories
have been used for all analyses.
 The Mineral Resource statement
relates to global estimates of tonnes
and grade.

was approximately 11 weeks).
Study status  The type and level of study
undertaken to enable Mineral
Resources to be converted to
Ore Reserves.
 The Code requires that a study
to at least Pre-Feasibility Study
level has been undertaken to
convert Mineral Resources to
Ore Reserves. Such studies will
have been carried out and will
have determined a mine plan
that is technically achievable
and economically viable, and
that material Modifying Factors
have been considered.
 An updated PFS study was prepared to
convert a portion of the Mineral
Resource to Ore Reserves.
 As part of the Authier updated PFS
study, a mine plan was developed that
was technically achievable and
economically viable. This mine plan
considered material Modifying factors
such as mining, processing, metallurgy,
infrastructure, economic, marketing,
legal, environmental, social and
regulatory.
Cut-off
parameters
 The basis of the cut-off grade(s)
or quality parameters applied.
 The Mineral Resource provided was a
geologically domained resource; this
geological model was evaluated to
determine which block produced cash
surplus when treated as ore.
 The marginal cut-off grade was
calculated at 0.35 % Li2O. However, in
order to optimize the Project economic
return, it was decided to use a higher
number (a cut-off grade of 0.45% Li2O)

  • The infrastructure requirements of the selected mining methods.

  • administration costs) in order to determine to what extent the deposit can be mined profitably.

  • The mining method is based on open pit mining.

  • The pit that has been designed for the Authier deposit is approximately 1,000 m long and 600 m wide at surface with a maximum pit depth from surface of 200 m. The total surface area of the pit is roughly 400,000 m2.

  • Overall slope angle: 40° to 55° (South and North walls respectively) in rock and 30° in overburden, in accordance with the geotechnical recommendations

  • Face angle: 60º and 77º (South and North walls respectively)

  • Bench height: 6 m for single bench and 12 m for double bench.

  • Safety berm: 6 m width (1 safety berm at each 12 m vertically)

  • Ramp grade: 10%, acceptable for CAT 775G haul trucks or their equivalents

  • Ramp width of 13.0 m (single lane) and 20.0 m (double lanes) following industry practice standards.

  • The haul roads were designed to accommodate the use of conventional mining trucks such as a CAT 775G (63 t payload truck, with 5.3 m width) or equivalent.

  • As such, the running surface has been designed to 16.8 m width. The allowance for berms and ditches increases the overall haul road width to 20 m.

  • Major assumptions for pit optimization include: ore production rate of 0.7 Mtpa; 82% recovery of Li2O as 6.00% Spodumene concentrate; total Ore Based Cost of CAD$ 32.86 /t treated; and overall mining cost of 3.10 CAD$/t mined. The NPV has been calculated with a selling price of 550 US$/t of concentrate at a discount rate of 8%. However, the economic parameters used at the time of the pit optimization do not necessarily corroborate those calculated or used in the PFS.

 The mining dilution was estimated at
2%, and the Ore Losses have also been
estimated at 5%. This is to take into
account the fact that some waste
material will be added into the Ore
stream going to the Processing plant
and that some of the Ore material will
be directed to the Waste dump. The
grade of the dilution material (added
to the Ore stream) was estimated as
an average value of 0% Li2O.
 The addition of mining dilution resulted
in lowering the Li2O grade of the
Mineral Reserves from 1.05% to 1.03%
Li2O.
 In order to access these reserves, 5.04
Mt of overburden and 76.02 Mt of
waste rock must be mined. This total
waste quantity of 81.06 Mt results in a
stripping ratio of 6.95 to 1.
 The overburden thickness averages
approximately 6 m and ranges from 0
to 12 m.
 All the mineralized material classified in
the inferred category was considered
as waste for the Pit Optimization
process.
 Mining infrastructure includes, ROM
pad, tailings pad, overburden and
waste rock stockpiles haul roads,
workshops and other buildings.
Metallurgical
factors or

 The metallurgical process
proposed and the
appropriateness of that process
to the style of mineralisation.
 Whether the metallurgical
process is well-tested
technology or novel in nature.
 The nature, amount and
representativeness of
metallurgical test work
undertaken, the nature of the
metallurgical domaining
applied and the corresponding
metallurgical recovery factors
applied.
 Any assumptions or allowances
made for deleterious elements.
 The existence of any bulk
sample or pilot scale test work
and the degree towhichsuch
 In 2017, two new representative
samples were prepared and flotation
testing undertaken using different test
conditions including diluted and un-
diluted, and with site water. The
program demonstrated the ability to
produce concentrate grades over 6%
at metallurgical recoveries over 80%
Li20.
 Wave International have designed a
concentrator plant to process 700,000
tpa of ore feed using conventional
flotation technology suitable for a
pegmatite orebody.
 The ore will be crushed to a P806mm in
three stages using a jaw crusher and
two-stages of secondary cone
crushing. The crushed ore will be stored
under a protected dome prior to

P80180 µ. The ground ore will be
passed through a magnetic separation
circuit to remove iron and then de-
slimed prior to mica flotation. Following
mica flotation, the flotation will pass
through attrition scrubbing circuit prior
to spodumene flotation.
 Further metallurgical optimisation and
enhancement to improve the
metallurgical recoveries and
concentrate grades is underway.
Historically, recoveries of up to 85%
have been achieved in certain parts of
the deposit and further testing is
required to ascertain whether this can
be extended homogenously across the
deposit.
 Bench scale Heavy liquid separation
(HLS) tests were performed on five (5)
randomly selected composites; AMET1,
AMET3, AMET6, AMET9 and AMET10.
Overall, the results of this testing
program indicated that DMS was not a
viable process option.
 A third HLS/DMS program is currently
underway to test additional
possibilities.
 All technologies proposed are proven
and well tested with easily sourced
components.
 Potential deleterious elements have
not been observed. Iron content of
Authier concentrate is too high to
supply the ceramics or glass industry.
 A pilot metallurgical testing program is
planned to commence in December
2017. A 5 tonnes sample is being

  • considered and, where responsible for the Canadian applicable, the status of Environmental Assessment Act (2012). approvals for process residue Because the Project did not generate storage and waste dumps any “designated activity”, an impact should be reported. study under the Canadian Environmental Assessment Act is not required.

  • On the provincial side, no Environmental Impact Assessments (EIA) will be required for the Project as the proposed output remains less than 2,000 tpd (EQA Q-2, r.23). Mainly two provincial ministries will issue permits: the MERN and the MDDELCC. The Company is currently engaged with the local provincial authorities to establish the permitting regime for Authier.

  • Certificates of authorisation under provincial Environmental Quality Act (LQE), art.22, will have to be obtained from the MDDELCC for most of activities that may result in a change in the quality of the environment. In order to expedite the start of construction, preparation of the permit applications can begin before the completion of the Detailed Engineering.

  • An Environmental Baseline Studies (EBS) have been completed in October 2017 for the Authier project and results will be available over the following months. However, previous studies were conducted during 2012 by Dessau and GFE and didn’t return environmental issues. Activities by DESSAU and GFE were performed to determine constraints linked to water and sediments quality and to environmental (physical, biological, human) impact.

  • Whilst the environmental study didn’t highlight any significant environmental issues, it recommended a high-level focus on water and tailings management. As such, the Company has engaged consulting firms to undertake a number of updated studies at part of this PFS, including:

  • Best practice tailings and waste rock disposal options. The PFS contemplates

that the best practice is producing filtered tailings will be co-disposed with the waste rock in order to facilitate water management and reduce the footprint;  Progressive site reclamation and remediation planning during operation and for end of mine activities;  Geochemical characterization program of waste rock and tailings. Results showed that the waste rocks and tailings are not acid generating and don’t leach heavy metals. This is consistent with the experience of other nearby similar deposits and operations;  A hydrogeological study to assess the hydrogeological conditions prevailing in the area, the current quality of the groundwater, and identify any potential impacts on the project groundwater, plan the pumping activities, and to provide information for the geotechnical engineering and geo-mechanics of the project;  A rehabilitation and closure plan is a requirement under the “Loi sur les mines”. It must be approved before the mining lease is issued, and a financial guarantee to fully implement the plan must be provided in three payments in the first two years following the approval of the plan.  Mining lease applications are initiated through the Ministère de l’Énergie et des Ressources naturelles (“MERN”). A mining lease will be granted only when the following conditions are fulfilled:  Completion of a Feasibility Study;  Completion of a scoping and marketing study for processing within Quebec.  Certificate of authorisation stipulated in sections 22, 31.5, 165 and 201 of the Environment Quality Act has been issued; and  A survey plan has been formalized by the Office of the Surveyor-General of Québec.  Before a mining lease can be granted for a metal mine project where the mine has a production capacity of less

than 2,000 metric tons per day, a
public consultation, initiated by the
proponent, must be held in the region
in which the mine will be located. The
Company has initiated early
discussions with the La Motte Council
outlining the plans for the
development of the Authier project.
 A waste rock material and overburden
stockpiles will be erected at proximity
of the mine entrance/exit. They will
have a volume of approximately 38.5
Mm³ and 3.3 Mm³ respectively. They
will be strategically located to minimize
hauling distances, and thus the size of
the mining fleet.
 A Community Relations Program is
being developed to approach and
engage local stakeholders. This
program will include information
sessions and consultations with
municipalities, landowners, First Nation
community, non-governmental
environmental organizations and
recreational associations.
Infrastructure  The existence of appropriate
infrastructure: availability of land
for plant development, power,
water, transportation
(particularly for bulk
commodities), labour,
accommodation; or the ease
with which the infrastructure
can be provided, or accessed.
 The Authier project is situated 45
kilometres north-west of the city of Val
d’Or, a major mining service centre,
with several operating mines and
active exploration companies, situated
in the Province of Quebec.Val d’Or is
located approximately 466 kilometres
north-east of Montreal.
 The project is easily accessed by a
rural road network connecting to a
national highway a few kilometres east
of the project site.
 The transcanadian railway is located
around 20 km south of Authier. Such
railway has the capacity to ship the
concentrate to both Atlantic and
Pacific coast. A sideway located in
Cadillac, 27 km southwest of Authier by
route, could be used after build a
storage facility capable to store 1,500 t
of Authier´s concentrate.
 The regional resources regarding
labour force, supplies and equipment
are sufficient, the area being well
served by geological and mining
servicefirms. The cities of Vald’Orand

___ Page 41 of 48

==> picture [595 x 52] intentionally omitted <==

==> picture [595 x 52] intentionally omitted <==

Rouyn-Noranda are regional centers
for the Abitibi region and have the
necessary infrastructures and
workforce to support a mining
operation.
 The electrical power will easily be
available from Hydro-Quebec. The
estimated power demand for the
project is estimated to be 5.3 MW
 Based on a preliminary evaluation from
Hydro-Québec, a total of 2.7 km of
new network power line needs to be
installed in order to supply power to
Authier mine site
 No detailed investigations into the
water requirements and supply sources
have been carried out. Primary water
sources would be from pit dewatering,
collection of surface runoff in natural or
artificial structures, existing ponds,
reclaim water from the TMF and other
sources. Studies on the water supply
balance and remedial measures will
need to be conducted as part of the
next developing stages.
Costs  The derivation of, or
assumptions made, regarding
projected capital costs in the
study.
 The methodology used to
estimate operating costs.
 Allowances made for the
content of deleterious elements.
 The source of exchange rates
used in the study.
 Derivation of transportation
charges.
 The basis for forecasting or
source of treatment and refining
charges, penalties for failure to
meet specification, etc.
 The allowances made for
royalties payable, both
Government and private.
 Project Capital was derived on the
following basis:
 The overall plant layout and
equipment sizing was prepared with
sufficient detail to permit and
assessment of the engineering
quantities for the majority of the
facilities for concrete, steelwork and
mechanical items. The layouts enabled
preliminary estimates of quantities to
be taken for all areas.
 Unit rates for labour and materials were
obtained from quotations from
fabricators and contractors
experienced in the scale and type of
work in the region
 Fixed and firm pricing was obtained for
major items of equipment. Budget
pricing was obtained from reputable
suppliers for minor items of equipment
with the exception of low value items
which were costed from Wave
Consultant’s database of recent
project costs.

 Contingency has been applied to account for the accuracy of the estimate.  Mining capital costs include site establishment costs and mobilization of equipment and pre-production costs. Pre-production includes clearing and stockpiling of topsoil.  Process Plant Operating costs were compiled by Wave Consulting using first principal estimation and industry experience for projects of similar size and nature in the region.  Manning level and pay rates were derived by Sayona and Wave Consulting to suit the proposed process plant and scale of operation for the Quebec province location.  Consumables pricing were sourced from vendor quotes where applicable.  Flotation reagent consumption was based on metallurgical test work, the production schedule and factored from similar operations.  Crushing and grinding energy and consumables were derived from the comminution test work at SGS Lakefield Laboratory and vendor quotes.  Mine operating expenditure was based on mining volumes, and hourly operating costs for all the different mining equipment that are intended to be operated by the Company. The Company’s team for Mine Management and Technical Services were based on personal levels required to manage the operation and comparable salary in the Province of Quebec  The selected Exchange rate is consistent with the exchange ratio data over the last 12 months.  Transport and part charges were derived from quotations by reputable suppliers.  Allowances were made for marketing and grade variability in the revenue factors.  The Quebec Government doesn’t impose any royalties on mineral production. However, Authier is subject

to a number of vendor royalty
payments.
Revenue
factors
 The derivation of, or
assumptions made regarding
revenue factors including head
grade, metal or commodity
price(s) exchange rates,
transportation and treatment
charges, penalties, net smelter
returns, etc.
 The derivation of assumptions
made of metal or commodity
price(s), for the principal metals,
minerals and co-products.
 Spodumene pricing was based on an
average of forecasts fromDeutsche
Bank, Cannacord, UBS and Edison
Research
 Spodumene revenue factors were:
 The average head grade of the Ore
has been estimated at 1.03% Li2O over
the 17 years of processing operation
 Processing recoveries applied at 82%.
 Spodumene average price of USD 609
/ t for 6.00% Li2O content
 Exchange ratio of 0.76 CAD:USD

 Lithium concentrate produced from
Authier will be classed as Chemical
Grade specification, principally due to
its high iron content. The principal
markets for Chemical Grade
concentrates are battery, lubricants,
aluminum smelting, and
pharmaceuticals applications.
 The lithium market is currently
experiencing a major demand shift
driven by the increasingly critical role
of the lithium-ion battery technology
for storage applications in the
automotive, consumer electronics and
electricity storage/distribution sectors.
 There are a number of pricing
benchmarks for various lithium
products (lithium carbonate or lithium
hydroxide whose prices can vary
significantly depending on grade) but
the most relevant for spodumene
concentrate pricing is the Lithium
Carbonate Equivalent (LCE) price. This
pricing data is typically only available
via paid subscription services, such as
Benchmark Mineral Intelligence, and its
limited by the number of transactions
available in the public domain.
 For the Authier PFS, Spodumene pricing
was set to 609 USD$/t long-term real,

 The Company is exploring a number of
options for selling high-quality
spodumene concentrate that will be
produced from a future operation at
Authier. This includes direct sales of
concentrate to converters that
produce lithium products suitable for
the global battery markets. Strong
demand for the lithium products has
driven concentrate prices to record
levels.
 The company recently signed a non-
