Sampling
techniques

• Nature and quality of sampling (eg cut
  channels, random chips, or specific
  specialized 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
  mineralization 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 pulverized 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
  mineralization types (eg submarine
  nodules) may warrant disclosure of
  detailed information.

• Core sampling protocols meet industry standard
  practices.
• Core sampling is guided by lithology as determined
  during geological logging (i.e., by a geologist). All
  pegmatite intervals are sampled in their entirety (half-
  core), regardless if spodumene mineralization is noted
  or not (in order to ensure an unbiased sampling
  approach) in addition to ~1 to 3 m of sampling into the
  adjacent host rock (dependent on pegmatite interval
  length) to “bookend” the sampled pegmatite.
• The minimum individual sample length is typically 0.3-
  0.5 m and the maximum sample length is typically
  2.0 m. Targeted individual pegmatite sample lengths
  are 1.0 m.
• All drill core is oriented to maximum foliation prior to
  logging and sampling and is cut with a core saw into
  half-core pieces, with one half-core collected for assay,
  and the other half-core remaining in the box for reference.
• Core samples collected from drill holes were shipped to
  SGS Canada’s laboratory in Val-d’Or, QC, for sample
  preparation (code PRP89 special) which included
  drying at 105°C, crush to 90% passing 2 mm, riffle split
  250 g, and pulverize 85% passing 75 microns. Core
  sample pulps were shipped by air to SGS Canada’s
  laboratory in Burnaby, BC, where the samples were
  homogenized and subsequently analyzed for multi-
  element (including Li and Ta) using sodium peroxide
  fusion with ICP-AES/MS finish (codes GE_ICP91A50
  and GE_IMS91A50).

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).

• NQ size core diamond drilling was completed for all
  holes. Core was not oriented.

Drill sample
recovery

• Method of recording and assessing core
  and chip sample recoveries and results
  assessed.
• Measures taken to maximize 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.

• All drill core was geotechnically logged following
  industry standard practices, and includes TCR, RQD,
  ISRM, and Q-Method. Core recovery is very good and
  typically exceeds 90%.

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.

• Upon receipt at the core shack, all drill core is pieced
  together, oriented to maximum foliation, metre marked,
  geotechnically logged (including structure), alteration
  logged, geologically logged, and sample logged on an
  individual sample basis. Core box photos are also
  collected of all core drilled, regardless of perceived
  mineralization. Specific gravity measurements of
  pegmatite are also collected at systematic intervals for
  all pegmatite drill core using the water immersion
  method, as well as select host rock drill core. 
• The logging is qualitative by nature, and includes
  estimates of spodumene grain size, inclusions, and
  model mineral estimates.
• These logging practices meet or exceed current industry
  standard practices.

Sub-sampling

techniques and

sample preparation

• If core, whether cut or sawn and
  whether quarter, half or all core taken.
• If non-core, whether riffled, tube
  sampled, rotary split, etc and whether
  sampled wet or dry.
• For all sample types, the nature, quality
  and appropriateness of the sample
  preparation technique.
• Quality control procedures adopted for
  all sub-sampling stages to maximize
  representivity of samples.
• Measures taken to ensure that the
  sampling is representative of the in situ
  material collected, including for
  instance results for field
  duplicate/second-half sampling.
• Whether sample sizes are appropriate to
  the grain size of the material being
  sampled.

• Drill core sampling follows industry best practices.
  Drill core was saw-cut with half-core sent for
  geochemical analysis and half-core remaining in the
  box for reference. The same side of the core was
  sampled to maintain representativeness.
• Sample sizes are appropriate for the material being
  assayed.
• A Quality Assurance / Quality Control (QAQC)
  protocol following industry best practices was
  incorporated into the program and included systematic
  insertion of quartz blanks and certified reference
  materials (CRMs) into sample batches at a rate of
  approximately 5% each. Additionally, analysis of pulp-
  split and course-split sample duplicates were completed
  to assess analytical precision at different stages of the
  laboratory preparation process, and external
  (secondary) laboratory pulp-split duplicates were
  prepared at the primary lab for subsequent check
  analysis and validation at a secondary lab.
• All protocols employed are considered appropriate for
  the sample type and nature of mineralization and are
  considered the optimal approach for maintaining
  representativeness in sampling.

Quality of assay
data and laboratory

tests

• The nature, quality and appropriateness
  of the assaying and laboratory
  procedures used and whether the
  technique is considered partial or total.
• For geophysical tools, spectrometers,
  handheld XRF instruments, etc, the
  parameters used in determining the
  analysis including instrument make and
  model, reading times, calibrations
  factors applied and their derivation, etc.
• Nature of quality control procedures
  adopted (eg standards, blanks,
  duplicates, external laboratory checks)
  and whether acceptable levels of
  accuracy (ie lack of bias) and precision
  have been established.

• Core samples collected from drill holes were shipped to
  SGS Canada’s laboratory in Val-d’Or, QC, for standard
  sample preparation (code PRP89 special) which
  included drying at 105°C, crush to 90% passing 2 mm,
  riffle split 250 g, and pulverize 85% passing 75
  microns. Core sample pulps were shipped by air to SGS
  Canada’s laboratory in Burnaby, BC, where the samples
  were homogenized and subsequently analyzed for
  multi-element (including Li and Ta) using sodium
  peroxide fusion with ICP-AES/MS finish (codes
  GE_ICP91A50 and GE_IMS91A50).
• The Company relies on both its internal QAQC
  protocols (systematic use of blanks, certified reference
  materials, and external checks), as well as the
  laboratory’s internal QAQC.
• All protocols employed are considered appropriate for
  the sample type and nature of mineralization and are
  considered the optimal approach for maintaining
  representativeness in sampling.

Verification of
sampling and
assaying

• The verification of significant
  intersections by either independent or
  alternative company personnel.
• The use of twinned holes.
• Documentation of primary data, data
  entry procedures, data verification, data
  storage (physical and electronic)
  protocols.
• Discuss any adjustment to assay data.

• Intervals are reviewed and compiled by the VP
  Exploration and Project Managers prior to disclosure,
  including a review of the Company’s internal QAQC
  sample analytical data.
• Data capture utilizes MX Deposit software whereby
  core logging data is entered directly into the software
  for storage, including direct import of laboratory
  analytical certificates as they are received. The
  Company employs various on-site and post QAQC
  protocols to ensure data integrity and accuracy.
• Adjustments to data include reporting lithium and
  tantalum in their oxide forms, as it is reported in
  elemental form in the assay certificates. Formulas used
   are Li₂O = Li x 2.153, and Ta₂O₅ = Ta x 1.221.

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.

• Each drill hole’s collar has been surveyed with a RTK
  Trimble Zephyr 3 (or temporarily using a handheld
  GPS). 
• The coordinate system used is UTM NAD83 Zone 18.
• The Company completed a property-wide LiDAR and
  orthophoto survey in August 2022, which provides
  high-quality topographic control.
• The quality and accuracy of the topographic controls
  are considered adequate for advanced stage exploration
  and development, including mineral resource
  estimation

.

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 hole collar spacing is dominantly grid based at
  ~100 m; however, tightens to ~50 m in multiple areas,
  and widens to ~150 m in a small number of areas.
  Subsurface pegmatite pierce points generally reflect the
  collar spacing at CV5; however, are subject to typical
  downhole deviation.
• It is interpreted that the drill spacing will be sufficient
  to support a mineral resource estimate.
• Core sample lengths typically range from 0.5 to 1.5 m
  and average ~1 m. Sampling is continuous within all
  pegmatite encountered in the drill hole.
• 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
  mineralized structures is considered to
  have introduced a sampling bias, this
  should be assessed and reported if
  material.

• No sampling bias is anticipated based on structure
  within the mineralized body.
• At CV5, the principal mineralized body and adjacent
  lenses are steeply dipping resulting in oblique angles of
  intersection with true widths varying based on drill hole
  angle and orientation of pegmatite at that particular
  intersection point. i.e., the dip of the mineralized
  pegmatite body has variations in a vertical sense and
  along strike, so the true widths are not always apparent
  until several holes have been drilled (at the appropriate
  spacing) in any particular drill-fence.

Sample security

• The measures taken to ensure sample
  security.

• Samples were collected by Company staff or its
  consultants following specific protocols governing
  sample collection and handling. Core samples were
  bagged, placed in large supersacs for added security,
  palleted, and shipped directly to Val-d’Or, QC, being
  tracked during shipment along with Chain of Custody.
  Upon arrival at the laboratory, the samples were cross-
  referenced with the shipping manifest to confirm all
  samples were accounted for. At the laboratory, sample
  bags are evaluated for tampering.

Audits or reviews

• The results of any audits or reviews of
  sampling techniques and data.

• A review of the sample procedures for the Company’s
  2021 fall drill program (CF21-001 to 004) and 2022
  winter drill program (CV22-015 to 034) was completed
  by an Independent Competent Person and deemed
  adequate and acceptable to industry best practices

  Technical Report on the Corvette Property, Quebec,
  Canada”, by Alex Knox, M.Sc., P.Geol., Issue Date of
  June 27^th, 2022.)
• A review of the sample procedures through the
  Company’s 2023 winter drill program was completed
  by an independent Competent Person with respect to the
  CV5 Pegmatite’s maiden mineral resource estimate and
  deemed adequate and acceptable to industry best
  practices (discussed in a technical report titled ” NI

Mineral tenement
and land tenure

status

• Type, reference name/number, location
  and ownership including agreements or
  material issues with third parties such as
  joint ventures, partnerships, overriding
  royalties, native title interests, historical
  sites, wilderness or national park and
  environmental settings.
• The security of the tenure held at the
  time of reporting along with any known
  impediments to obtaining a licence to
  operate in the area.

• The Corvette Property is comprised of 417 CDC claims
  located in the James Bay Region of Quebec, with
  Patriot Battery Metals Inc. the registered title holder for
  all of the claims. The Property’s northern border is
  located within approximately 6 km to the south of the
  Trans-Taiga Road and powerline infrastructure
  corridor. At the Property, the CV5 Spodumene
  Pegmatite is situated approximately 13.5 km south of
  the regional and all-weather Trans-Taiga Road and
  powerline infrastructure. The CV13 Spodumene
  Pegmatite is located approximately 3.15 km along
  strike to the southwest of the CV5 Spodumene
  Pegmatite.
• The Company holds 100% interest in the Property
  subject to various royalty obligations depending on
  original acquisition agreements. DG Resources
  Management holds a 2% NSR (no buyback) on 76
  claims, D.B.A. Canadian Mining House holds a 2%
  NSR on 50 claims (half buyback for $2M) and Osisko
  Gold Royalties holds a sliding scale NSR of 1.5-3.5%
  on precious metals, and 2% on all other products, over
  111 claims. The vast majority of the CV13 Spodumene
  Pegmatite, as is currently delineated, is not subject to a
  royalty.
• The Property does not overlap any atypically sensitive
  environmental areas or parks, or historical sites to the
  knowledge of the Company. There are no known
  hinderances to operating at the Property, apart from the
  goose harvesting season (typically mid-April to mid-
  May) where the communities request helicopter flying
  not be completed, and potentially wildfires depending
  on the season, scale, and location. 
• Claim expiry dates range from September 2024 to
  September 2026.

Exploration done
by other parties

• Acknowledgment and appraisal of
  exploration by other parties.

• No core assay results from other parties are disclosed
  herein.
• The most recent independent Property review was a

  Corvette Property, James Bay Region, Québec,
  Canada”, by Todd McCracken, P.Geo., of BBA
  Engineering Ltd., and Ryan Cunningham, M.Eng.,
  P.Eng., of Primero Group Americas Inc., Effective Date
  of June 25, 2023, and Issue Date of September 8, 2023.

Geology

• Deposit type, geological setting and
  style of mineralization.

• The Property overlies a large portion of the Lac Guyer
  Greenstone Belt, considered part of the larger La
  Grande River Greenstone Belt and is dominated by
  volcanic rocks metamorphosed to amphibolite facies.
  The claim block is dominantly host to rocks of the
  Guyer Group (amphibolite, iron formation,
  intermediate to mafic volcanics, peridotite, pyroxenite,
  komatiite, as well as felsic volcanics). The amphibolite
  rocks that trend east-west (generally steeply south
  dipping) through this region are bordered to the north
  by the Magin Formation (conglomerate and
  wacke) and to the south by an assemblage of tonalite, granodiorite,
  and diorite, in addition to metasediments of the Marbot
  Group (conglomerate, wacke). Several regional-scale
  Proterozoic gabbroic dykes also cut through portions of
  the Property (Lac Spirt Dykes, Senneterre Dykes).
• The geological setting is prospective for gold, silver,
  base metals, platinum group elements, and lithium over
  several different deposit styles including orogenic gold
  (Au), volcanogenic massive sulfide (Cu, Au, Ag),
  komatiite-ultramafic (Au, Ag, PGE, Ni, Cu, Co), and
  pegmatite (Li, Ta).
• Exploration of the Property has outlined three primary
  mineral exploration trends crossing dominantly east-
  west over large portions of the Property – Golden Trend
  (gold), Maven Trend (copper, gold, silver), and CV
  Trend (lithium, tantalum). The CV5 and CV13
  spodumene pegmatites are situated within the CV
  Trend. Lithium mineralization at the Property,
  including at CV5 and CV13, is observed to occur within
  quartz-feldspar pegmatite, which may be exposed at
  surface as high relief ‘whale-back’ landforms. The
  pegmatite is often very coarse-grained and off-white in
  appearance, with darker sections commonly composed
  of mica and smoky quartz, and occasional tourmaline. 
• The lithium pegmatites at Corvette are categorized as
  LCT Pegmatites. Core assays and ongoing
  mineralogical studies, coupled with field mineral
  identification and assays, indicate spodumene as the
  dominant lithium-bearing mineral on the Property, with
  no significant petalite, lepidolite, lithium-phosphate
  minerals, or apatite present. The pegmatites also carry
  significant tantalum values with tantalite indicated to be
  the mineral phase.

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:
  • easting and northing of the drill hole
    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 this is the case.

• Drill hole attribute information is included in Table 2
  herein.
• Pegmatite intersections of <2 m are not typically
  presented as they are considered insignificant.

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.

• Length weighted averages were used to calculate grade
  over width.
• No specific grade cap or cut-off was used during grade
  width calculations. The lithium and tantalum average of
  the entire pegmatite interval is calculated for all
  pegmatite intervals over 2 m core length, as well as
  higher grade zones at the discretion of the geologist. 
  Pegmatites have inconsistent mineralization by nature,
  resulting in some intervals having a small number of
  poorly mineralized samples included in the calculation.
  Non-pegmatite internal dilution is limited to typically
  <3 m where relevant and intervals indicated when
  assays are reported.
• No metal equivalents have been reported.

Relationship

between
mineralization
widths and intercept
lengths

• These relationships are particularly
  important in the reporting of
  Exploration Results.
• If the geometry of the mineralization
  with respect to the drill hole angle is
  known, its nature should be 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’).

• Geological modelling is ongoing on a hole-by-hole
  basis as CV5 is drilled. However, current interpretation
  supports a principal, large pegmatite body of near
  vertical to steeply dipping orientation, flanked by
  several subordinate pegmatite lenses (collectively, the
  ‘CV5 Spodumene Pegmatite’)
• All reported widths are core length. True widths are not
  calculated for each hole due to the relatively wide drill
  spacing at this stage of delineation and the typical
  irregular nature of pegmatite, as well as the varied drill
  hole orientations. As such, true widths may vary widely
  from hole to hole.

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.

• Please refer to the figures included herein as well as
  those posted on the Company’s website.

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.

• Please refer to the table(s) included herein as well as
  those posted on the Company’s website.
• Results for pegmatite intervals <2 m are not reported.

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 characteristics;
  potential deleterious or contaminating
  substances.

• The Company is currently completing baseline
  environmental work over the CV5 and CV13 pegmatite
  area. No endangered flora or fauna have been
  documented over the Property to date, and several sites
  have been identified as potentially suitable for mine
  infrastructure. 
• The Company has completed a bathymetric survey over
  the shallow glacial lake which overlies a portion of the
  CV5 Spodumene Pegmatite. The lake depth ranges
  from <2 m to approximately 18 m, although the
  majority of the CV5 Spodumene Pegmatite, as
  delineated to date, is overlain by typically <2 to 10 m of
  water.
• The Company has completed preliminary metallurgical
  testing comprised of HLS and magnetic testing, which
  has produced 6+% Li₂O spodumene concentrates at
  >70% recovery on both CV5 and CV13 pegmatite
  material, indicating DMS as a viable primary process
  approach, and that both CV5 and CV13 could
  potentially feed the same process plant. A DMS test on
  CV5 Spodumene Pegmatite material returned a
  spodumene concentrate grading 5.8% Li₂O at 79%
  recovery, strongly indicating potential for a DMS only
  operation to be applicable.
• Various mandates required for advancing the Project
   towards economic studies have been initiated, including
  but not limited to, environmental baseline, metallurgy,
  geomechanics, hydrogeology, hydrology, stakeholder
  engagement, geochemical characterization, as well as
  transportation and logistical studies.

Further work

• The nature and scale of planned further
  work (eg tests for lateral extensions or
  depth extensions or large-scale step-out
  drilling).
• Diagrams clearly highlighting the areas
  of possible extensions, including the
  main geological interpretations and
  future drilling areas, provided this
  information is not commercially
  sensitive.

• The Company intends to continue drilling the
  pegmatites of the Corvette Property, focused on the
  CV5 Spodumene Pegmatite and adjacent subordinate
  lenses, as well as the CV13 Spodumene Pegmatite. At
  CV5, mineralization remains open along strike at both
  ends, and to depth along a significant portion of its
  length. At CV13, mineralization remains open along
  strike at both ends, and to depth.
