Avalon Receives Encouraging Ore-Sorting Test Results
from East Kemptville Tin Project, Yarmouth Co., Nova
Scotia
Toronto, Ontario--(Newsfile Corp. - September 17, 2018) -
Avalon Advanced Materials Inc.
(TSX: AVL) (OTCQX: AVLNF)
("Avalon" or the "Company") is pleased to announce that the Company has received positive results from an ore-sorting
testwork program conducted on samples of tin mineralization from its East Kemptville Tin Project ("East Kemptville" or the
"Project"). As discussed in the Company's news release dated
July 24, 2018
, these results provide further encouragement that
ore-sorting technology can be successfully implemented at East Kemptville to reduce both capital and operating costs and to
reduce the volume of tailings generated from the proposed operation.
Sensor-based ore-sorting ("SBS") is an emerging technology seeing increasing application in the mining industry. It involves the
scanning of individual rock particles on a conveyor using various types of available sensor technologies. Depending on the
chemical, mineralogical or physical characteristics, the particles of value are individually identified and separated from the
"rejects" by applying either a mechanical, hydraulic or, in the case of East Kemptville, a pneumatic process.
The successful application of an ore-sorting process offers a number of potential benefits through the rejection of low or non-
mineralized waste rock before it is fed into the processing plant. This can lead to a significant reduction in the size of the plant,
along with attendant reductions in both capital and operating costs. It may also allow for the economic processing of low grade
feed materials that would otherwise be un-economic to treat.
The recent work was conducted by Cronimet Mining Processing SA (Pty) Ltd ("CMPSA"), who are providing technical and
metallurgical services to Avalon in relation to the East Kemptville Project. CMPSA has also expressed interest in partnering with
Avalon on the development of the Project.
Drill core samples from the in-ground resources at East Kemptville were delivered in July 2018 to a test facility in Kentucky, USA
in order to determine the amenability of East Kemptville tin mineralization for beneficiation utilizing sorting technology. Samples
varying from relatively high-grade to low-grade tin concentrations were scanned using a multisensory sorter platform. Based on
these scans an algorithm was developed to allow for the separation of the material during the test campaign.
The feed stock used during the test campaign contained 0.11% Sn, 0.06% Cu and 0.11% Zn. The first step of the testwork
produced an upgraded product containing 0.47% Sn and a product mass yield of 12%. Recovery versus grade data also
showed that SBS can be used to recover the zinc ore mineral sphalerite (which also contains indium) from this resource. The
zinc-indium feed was successfully upgraded to 0.23% Zn in the first step, while copper content remained low.
Similar positive results were achieved in a preliminary ore sorting test program conducted in 2017 using material from the low
grade stockpile, confirming that SBS can be successfully employed to upgrade both the in-ground tin resource as well as the
stockpiled material.
Next Steps
Based on these results, CMPSA has recommend that a detailed sampling campaign be conducted on the low grade stockpile,
followed by an extensive bulk testwork program using a pilot scale ore sorting plant to test the recovery of valuable minerals on a
pilot scale. CMPSA will be visiting the East Kemptville site in September to meet with Avalon and site representatives in order
to design and schedule the sampling program which is likely to involve the extraction of a bulk (~10 tonne) composite sample
sometime in October 2018. The test program, including writing of the technical report, is expected to take five to six months to
complete. This testwork, combined with a confirmation drilling program on the stockpile, will be utilized to finalize the small-scale
site re-development model to the Feasibility level of confidence, following which it is contemplated Avalon and Cronimet would
enter into a partnership for the joint development of the Project.

Technical Report
Further to the Company's news release of July 24, 2018, in which the results of its Preliminary Economic Assessment ("PEA")
were disclosed, the report entitled "The East Kemptville Tin Production and Site Remediation Project Preliminary Economic
Assessment, Nova Scotia, Canada" has now been filed on SEDAR and is
available on the Company's website
. In accordance
with the regulations under NI 43-101, it is noted that the PEA must be considered preliminary in nature, as it includes Inferred
mineral resources that are considered too speculative to have the economic considerations applied to them that would enable
them to be categorized as mineral reserves, and there is no certainty that the preliminary economic assessment will be realized.
