Toronto, Ontario--(Newsfile Corp. - October 26, 2017) - Avalon Advanced
Materials Inc. (TSX: AVL) (OTCQX: AVLNF) ("Avalon" or the "Company") is pleased to provide the following update on recent
activities on its Separation Rapids Lithium Project. The Company is focused on advancing its proposed Phase 1 lithium production
facility and has been analyzing various alternatives on flowsheets to meet the needs of potential battery materials and
glass-ceramics customers, as well as lithium mineral concentrate processors, that have expressed interest in the products. The
mineralogy of the Separation Rapids lithium resource, containing significant quantities of both petalite and lepidolite, provides
opportunities to produce both lithium carbonate and lithium hydroxide for battery makers and petalite as an industrial mineral for
glass makers. Accordingly, recent work on the resource block model following the spring drilling program has focused on generating
a detailed mineralogical model of the deposit.
Resource Update and Phase 1 Plant Design
As disclosed in the Company's News Release dated July 18, 2017, the spring drilling program
has generated considerable new data towards creating a detailed mineralogical model of the deposit. The four in-fill holes
contributed to a better understanding of resource geometry for mine planning purposes, in particular the spatial distribution of
the lepidolite rich sub-unit that comprises at least 20% of the known resource. The block model created will also help guide
further drilling planned for later this fall designed to expand the resource to depth.
Mapping mineralogical zonation in the deposit is integral to designing the flowsheet for the planned Phase 1 production facility
in order to maximize recoveries of lepidolite and petalite which will need to be concentrated separately. Initial testwork has
shown that lepidolite can be recovered as the first step in a sequential flotation process prior to flotation of petalite.
Concentrates of lepidolite are attracting increasing interest as a feedstock for production of lithium carbonate due to innovative
low cost process technology such as the L-Max® process of Lepidico Ltd. As reported in the Company's news release dated February 6, 2017, Avalon signed a letter of intent
with Lepidico under which it is contemplated that Avalon would sell a minimum of 15,000 tonnes per annum of lepidolite concentrate
produced from its Phase 1 plant to Lepidico for processing at Lepidico's planned Phase 1 commercial lithium carbonate production
facility. Lepidico now contemplates building this facility in Ontario. Avalon's Phase 1 plant would also include a circuit to
produce lithium hydroxide from petalite using the innovative new process flowsheet developed by the Company in 2016.
Numerous expressions of interest have been received from potential customers for the Company's lithium products and discussions
on off-take commitments are ongoing. Once off-take commitments are secured that define the priority lithium product lines, the
Company can finalize the design and engineering of the Phase 1 plant. With demand for lithium growing rapidly and few advanced
lithium projects ready to initiate production, the Company is well-positioned to bring a new supply to the market to serve priority
customers, once project financing is in place.
Summer Geological Mapping Program and Environmental Studies
The 2017 summer geological mapping and sampling program was carried out on the western part of the property covering the
new claims acquired earlier
this year. This work confirmed the potential for discovery of additional lithium pegmatite resources over a six
kilometre long trend to the west of the main Separation Rapids lithium deposit and has outlined six new pegmatite targets based on
either lithogeochemical or biogeochemical (vegetation) sampling. The westernmost occurrence, known as the Glitter pegmatite, has
never been drill-tested and yielded 1.18% Li2O over 14.8 metres in a continuous chip sample of
petalite mineralization collected this summer, confirming results obtained by previous operators.
Avalon completed site water, sediment, fish, invertebrate and endangered species studies in June and October that successfully
advanced the validation of the 1999 environmental baseline study. Sites for infrastructure, including the tailing management
facility, have been identified that do not impact fish or other wildlife habitat. Leachate work has been initiated on the site rock
and tailings to confirm that these have a low risk of generating acid rock drainage.
Avalon held a multi-Ministry meeting to review the project and associated permitting requirements as well as separate meetings
with the leadership of Wabaseemong Independent Nations and local representatives of the Métis Nation of Ontario to present the
project in detail, obtain input and discuss potential avenues for collaboration. Overall, the Company does not anticipate any
delays in securing the necessary permits and approvals to proceed with the Phase 1 production facility.
Future Work
Further drilling is planned in order to increase the total lithium resources in the main Separation Rapids lithium deposit,
which is open for expansion to depth below 200 metres with the deepest holes at present indicating similar widths and grades as in
the near surface holes. In addition, the lepidolite-rich sub-unit of the main pegmatite is also open for expansion to depth and
along strike.
Detailed mineralogical studies using several different techniques are underway in order to further quantify the lithium
pegmatite resources on the basis of mineralogy, as well as grades of the rare elements lithium, tantalum, cesium and rubidium.
Further geological work on the regional targets to the west is planned, in order to bring these to the drill stage. The Glitter
pegmatite merits drill-testing, along with the similarly untested petalite-bearing "West" pegmatite located just 800 metres west of
the main deposit. These can be tested in the same program as the deeper drilling planned for the main Separation Rapids lithium
resource.
