The Second Amending Agreement revises the terms of the NSR Agreement by establishing a deemed floor price of $0.135 for any share consideration that could potentially be payable to Orterra pursuant to the NSR Agreement.
The Company is also pleased to announce that it has received the conditional acceptance of the TSX Venture Exchange (the "Exchange") for the NSR Agreement, as amended by the Second Amending Agreement and has issued an aggregate of 3,900,000 common shares of the Company (the "Consideration Shares") to Orterra and made an initial cash payment of $175,000 in accordance with the terms of the amended NSR Agreement. The Consideration Shares are subject to a statutory hold period of four months and a day from the date of issuance in accordance with applicable securities laws.
