Avalon Advanced Materials Announces 28%
Increase in Measured and Indicated Mineral
Resources at JV Separation Rapids Project in
Ontario Canada
Toronto, Ontario--(Newsfile Corp. - February 27, 2025) -
Avalon Advanced Materials Inc.
(TSX: AVL)
(OTCQB: AVLNF) ("
Avalon
" or the "
Company
"), in partnership with its Joint-Venture ("
JV
") partner
SCR-Sibelco NV ("
Sibelco
"), is pleased to announce the results of an updated Mineral Resource
Estimate (MRE) for the Separation Rapids Project in Kenora, Ontario. This update builds on a year of
extensive drilling and data analysis, further refining the geological model of the previously announced
mineral resource estimate (MRE) from Avalon's
August 10, 2023, news release
.
The updated MRE for the Separation Rapids Project was prepared by SLR Consulting (Canada) Ltd., is
supported by 29 new drill holes and shows an increase of 28% in Measured + Indicated Mineral
Resource tonnage and a decrease of 13% in Inferred Mineral Resource tonnage compared to the 2023
MRE.
Key Highlights, effective January 30, 2025
As of January 30, 2025, open pit Measured and Indicated Mineral Resources are estimated at
10.73 Mt grading 1.27% Li
O for 136 kt contained Li
O
and Inferred Mineral Resources include
0.46 Mt grading 0.84% Li
O for 3.8 kt contained Li
O.
Compared to the 2023 MRE, a significant portion of the open pit mineral resources was upgraded
to the
Measured + Indicated category [+8% contained Li
O]
.
Combined open pit and underground Measured and Indicated Mineral Resources are estimated to
total
12.98 Mt grading 1.34% Li
O for 173 kt Li
O
. Additionally, Inferred Mineral Resources are
estimated to total
2.29 Mt grading 1.46% Li
O for 33 kt Li
O.
The MRE shows contained Li
O metal oxide increases of
28% in the Measured + Indicated
categories and decrease of 13% in the Inferred category.
Scott Monteith, President and CEO commented, "The updated Mineral Resource Estimate for the
Separation Rapids Project reflects the steady progress we have made in further defining this lithium
deposit. The increase in Measured and Indicated resources strengthens our understanding of the
project's potential and provides greater confidence as we continue to advance its development. We
remain committed to a disciplined and methodical approach, working closely with our JV partner,
Sibelco, to evaluate the best path forward in alignment with market conditions and Canada's critical
minerals strategy. We will embark on our 2025 exploration program and will strategically target Lilypad
for Spodumene and Cesium."

The updated MRE includes 29 new surface diamond drill holes totalling 8,921 m drilled since the
previous MRE completed by SLR in 2023 (SLR 2023). A summary of the updated 2025 MRE is

Notes
:
1. CIM (2014) definitions were followed for Mineral Resources.
2. Mineral Resources are reported using a 4.25% Li
2
O petalite concentrate price assumption of US$1,000/t with an exchange rate of US$1 = C$1.30.
3. Open pit Mineral Resources are reported from a block model regularized to 5 m x 3 m x 5 m parent block size at a 0.48% Li
O cut-off grade (COG)
in a Whittle resource shell. The Whittle resource shell and open pit COG are based on a mining cost of C$5.50/t, a general and administration (G&A)
cost of C$3.50/t, a processing cost of C$55.00/t, and a recovery of 40%.
4. Underground Mineral Resources are reported from a block model with a minimum sub-block size of 1 m within Deswik Stope Optimizer (DSO)
resource panels which were generated using a break-even 1.46% Li
O COG. The underground break-even COG grade is based on a mining cost of
C$120/t, a G&A cost of C$3.50/t, a processing cost of C$55.00/t, a recovery of 40%, and an exchange rate of US$1 = C$1.30. The DSO resource
panels are minimum 20 m by 10 m by 3 m wide.
5. Mineral Resources are reported based on a minimum thickness of approximately 3 m.
6. Average bulk densities were assigned to the blocks and range between 2.62 t/m³ and 2.66 t/m³ for the lithium pegmatite.
7. Numbers may not add due to rounding.
8. Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability.
The MRE was prepared in accordance with CIM (2014) definitions as incorporated by reference into
National Instrument 43-101 Standards of Disclosure for Mineral Projects (NI 43-101).
For 2025, Avalon will advance lithium mineral resource development activities at the Separation Rapids
Lithium Project, focusing on metallurgical, geotechnical, and environmental studies. The planned work
program includes extensive research on lithium mineral recovery and process development to further
delineate the potential of petalite, spodumene, and lepidolite. These efforts will involve mineralogical
analysis, flotation testing, and dense media separation studies. Additionally, geotechnical and
hydrological assessments will support the design of potential pit slopes, while ongoing environmental
baseline studies will aid future permitting efforts.
Field mapping completed in 2024 has successfully delineated the northwest trend of the Separation
Rapids pegmatite field, which extends from the Separation Rapids to the Snowbank and Glitter lithium
pegmatites. In 2025, targeted drilling will be conducted to define the lithium-bearing volumes along this
trend, enhancing the understanding of the project's resource potential.
