Toronto, ON – Avalon Advanced Materials Inc.(TSX: AVL and OTCQB: AVLNF) (“Avalon” or the “Company”) is pleased to announce that it has completed a non-brokered private placement today consisting of 10,000,000 flow-through shares at a price of $0.07 per share for gross proceeds of $700,000. Pursuant to Canadian securities laws, the securities issuable under this private placement are subject to a hold period which expires on April 22, 2019. 

The proceeds from this offering will be used primarily to fund planned work programs on the Company’s Separation Rapids Lithium Project (“Separation Rapids”) and East Kemptville Tin Project (“East Kemptville”). These include ongoing geological compilation work and metallurgical process testwork at Separation Rapids and a confirmation drilling program at East Kemptville to better define the internal grade distribution within the 6 million tonne stockpile of previously-mined tin mineralization. 

Ongoing work at East Kemptville includes preparation of the closure plan for the mining lease application, along with related environmental assessment work and community engagement. This work is expected to be completed in the first quarter of 2019.
