TORONTO, Ontario, May 14, 2019 -- Chantrell Ventures Corp. (NEX:CV.H) ("Chantrell") is pleased to announce that it has entered into a definitive arrangement agreement with Alexandria Minerals Corp. (TSX-V:AZX; OTCQB:ALXDF; Frankfurt:A9D) ("Alexandria") dated May 14, 2019 (the "Alexandria Arrangement Agreement"), pursuant to which, among other things, following the acquisition of certain non-core assets of Osisko Mining Inc. (OSK:TSX) ("Osisko Mining") by Chantrell, which will result in the reverse-take over (the "Reverse Take-Over") of Chantrell by Osisko Mining, the resulting issuer, which will be renamed "O3 Mining Inc." ("O3 Mining" or the "Resulting Issuer"), will acquire all of the issued and outstanding common shares of Alexandria pursuant to a statutory plan of arrangement under Section 192 of the Canada Business Corporations Act (the "Alexandria Arrangement").

Under the Alexandria Arrangement, shareholders of Alexandria ("Alexandria Shareholders") (other than Alexandria Shareholders validly exercising their dissent rights, if any) will be entitled to receive 0.010309 common shares of O3 Mining (on a post-Consolidation (as defined below) basis) in exchange for each Alexandria share held immediately prior to the effective time of the Alexandria Arrangement.

The Alexandria Arrangement has been priced based on deemed value of CDN $3.88 per common share of O3 Mining (on a post-Consolidation (as defined below) basis), being the purchase price of subscription receipts issued under Chantrell's CDN $18.2 million financing, and values the common shares of Alexandria at CDN $0.04 per share. The deemed purchase price of CDN $0.04 per common share of Alexandria represents a premium of approximately 18% over the five-day volume weighted average price ("VWAP") and approximately 23% over the 20-day VWAP of common shares of Alexandria on the TSX Venture Exchange as of the close of trading on May 13, 2019.

Walter Henry, the Interim President and Chief Executive Officer of Alexandria commented: "This transaction will fold Alexandria's key Val d'Or land package into O3 Mining's exploration properties at an early stage of O3 Mining's history. With its proven team of Québec explorers, strong balance sheet and available sources of funding, we believe that the O3 team will be able to apply their technical expertise to properly explore the Alexandria properties and maximize their long-term potential for all of O3 Mining's stakeholders, including Alexandria's current shareholders."

Chantrell is also pleased to announce, further to its announcements dated February 20, 2019 and March 27, 2019, that it has entered into a definitive arrangement agreement with Osisko Mining dated May 14, 2019 (the "Osisko Arrangement Agreement"), pursuant to which, among other things, certain non-core assets of Osisko Mining will be transferred to Chantrell, resulting in the Reverse Take-Over of Chantrell by Osisko Mining, by way of a statutory plan of arrangement under Section 182 of the Business Corporations Act (Ontario).

In addition, Alexandria has agreed to pay a termination fee of CDN $875,000 to Chantrell if the Alexandria Arrangement Agreement is terminated in certain circumstances, including if Alexandria enters into an agreement with respect to a superior proposal or if the Board of Directors of Alexandria (the "Alexandria Board") withdraws its recommendation with respect to the Alexandria Arrangement.
