Opta Minerals Inc. Announces Completion of Privatization by Speyside Equity

Waterdown, Ontario - April 6, 2016 - Opta Minerals Inc. ("Opta Minerals") (TSX: OPM) announced today the successful completion of the previously announced acquisition pursuant to which a subsidiary of Speyside Equity Fund I LP ("Speyside") acquired (the "Acquisition") all of the issued and outstanding common shares of Opta Minerals (the "Opta Shares") by way of amalgamation of Opta Minerals and a subsidiary of Speyside (the "Acquiror") pursuant to Section 181 of the Canada Business Corporations Act (the "Amalgamation").

Pursuant to the Amalgamation, all of the issued and outstanding Opta Shares held immediately prior to the Amalgamation, other than those held by the Acquiror, were converted, on a one-for-one basis, into redeemable shares ("Redeemable Shares") of the amalgamated corporation ("Amalco"), and each such Redeemable Share was immediately redeemed by Amalco in exchange for C$0.5202 per share payable in cash; or (ii) for those shareholders who completed an election prior to the deadline of March 29, 2016, C$0.3526 per share payable in cash plus an unsecured subordinated promissory note of Amalco (a "Note") in the principal amount of C$0.1676 per share.

The Acquiror has delivered to Equity Financial Trust Company, the depositary for the Amalgamation (the "Depositary"), sufficient funds and Notes to enable it to make payment of the consideration described in connection with the Amalgamation.

Letters of transmittal have been mailed to registered holders of Opta Shares and are also available under the profile of Opta at www.sedar.com. The letter of transmittal explains how registered holders of Opta Shares can deposit and obtain payment for their Opta Shares. Registered holders of Opta Shares must return their duly completed letters of transmittal to the Depositary in order to receive the consideration to which they are entitled for their Opta Shares. Non-registered holders of Opta Shares should carefully follow the instructions from the broker, investment dealer, bank, trust company, custodian, nominee or other intermediary that holds Opta Shares on their behalf.

It is anticipated that the Opta Shares will be delisted from the Toronto Stock Exchange on or about April 8, 2016.
