- Nature and quality of sampling (e.g. 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 (e.g. ‘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 (e.g. submarine nodules) may warrant disclosure of detailed information.
- A total of 20 diamond drill holes are reported in this news release for 5,324 m of
core. - The drill core is logged at one-metre intervals for lithology, mineralogy, metamorphic grade, alteration, mineralisation, and structure, prior
to marking out sample
intervals. - Lithological and sample logging is
done digitally using MXDeposit software and database. - All pegmatite intervals plus 15% of the wall rock on either side are sampled on one-metre intervals regardless of lithological contacts. Quartz veins greater than 50cm, or at the discretion of the logging geologist, veins that exhibit sulphide mineralisation are also
sampled on one-metre intervals. - Cut lines are drawn on sampled
intervals to ensure a consistent side of the core is sampled. - The sampler saws HQ core in half,
with half being submitted for analysis and
half remaining in the core box as a
record.

carefully reconstructed in a secure core
facility. - The core is logged geotechnically on a

- All pegmatite intervals plus 15% of the wall rock on either side are sampled on one-metre intervals regardless of lithological contacts. Quartz veins greater than 50cm, or at the discretion of the logging geologist, veins that exhibit sulphide mineralisation are also
sampled on one-metre
intervals. - Each sample represents one metre of drill core (minimum and maximum sample length of 1 m) and one
sample may contain both pegmatite and wall rock. - Cut lines are drawn on sampled
intervals to ensure a consistent side of the core is sampled. - The sampler saws HQ core in half, with half being submitted for analysis and
half remaining in the core box as a

taken to replace the unsampled portion of the core in the core box in the original orientation. - The drill-hole number and sample intervals are clearly entered into a sample book to back up the
digital logging
files. - The geologist staples the portion of the uniquely numbered sample ticket at the beginning of the corresponding sample interval in the core box, and the

- Core samples are delivered to ALS in Yellowknife, NWT, Canada for sample preparation and sample pulps are
sent for analysis to the ALS laboratory in North Vancouver, BC,
Canada. - The ALS Yellowknife and North Vancouver facilities are ISO 9001
and ISO/IEC 17025
certified. - Samples are dried, weighed, and crushed to at least 70% passing 2 mm, and a 1000 g split is pulverised to at least 85% passing 75 µm (ALS Method Code
PREP31B). - Ore grade Li analysis is completed on
a 0.2 g sub-sample using a sodium peroxide fusion with an inductively coupled plasma atomic emission spectroscopy finish (ICP-AES) (ALS Method Code ME-ICP82b). - A trace level multi-element
geochemical analysis is also completed on a 0.2 g sub-sample using a sodium peroxide fusion with an inductively coupled plasma mass spectrometry finish (ICP- MS) (ALS Method Code
ME-MS89L). - ALS has its own internal QA/QC program, which is reported in the
assay certificates, including the coarse reject and pulp duplicate
assays. - Li-FT’s QA/QC program comprises the systematic insertion of standards or certified reference materials (CRMs), blanks, and field duplicates in addition
to the establishment of documented sampling and analytical QA
protocols. - QC samples are inserted into the
sample sequence at a frequency of approximately 1 CRM, blank, and field duplicate QC sample per 25 routine samples. - Approximately 10% of samples
assayed have been QC samples in the drilling programs from 2023 to
2024. - Sample batches with suspected cross- sample contamination or certified reference materials returning assay values outside of the mean ± 3SD control limits are considered analytical failures by the Company and
assay reruns were requested when deemed warranted.

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
- Drillhole spacing varies by deposit,
from a maximum of 100m by 100m to a minimum of 50m by
50m. - The Competent Person considers the drillhole spacing adequate and appropriate to establish geological and grade continuity for the deposits and
for the estimation and classification of an MRE. - The drillhole assays were composited
to 1.0 m.
of data in relation to geological structure
- Whether the orientation of sampling achieves unbiased sampling of possible
structures and the extent to which this is known, considering the
deposit type. - If the relationship between
the drilling orientation and the orientation of key mineralised structures is considered
to have introduced a sampling bias, this should be assessed and reported if material.
- The orientation of the drillholes was typically perpendicular to the
interpreted strike of the pegmatite bodies and the orientation of the samples are considered
unbiased.

ensure sample
security.
- At all times samples were in the custody and control of the Company’s representatives until delivery to the laboratory where samples were held in
a secure enclosure pending processing.

techniques and data
- The Competent Person for Exploration Results reported here has reviewed
the field procedures used for sampling program at field and has compiled results from the original sampling and laboratory data. - No external audits were undertaken
on the
