Mainstream to Acquire Champagne Resources

Mainstream Minerals Corporation (TSX VENTURE:MJO) ("Mainstream" or the
"Company") and Champagne Resources Limited ("Champagne") are pleased to announce
that on March 12, 2014, Mainstream, Champagne and a wholly-owned subsidiary of
Mainstream ("Subco") entered into an amalgamation agreement (the "Amalgamation
Agreement") whereby Mainstream will acquire all of the issued and outstanding
shares of Champagne, an arm's length party (the "Transaction").


Pursuant to the Amalgamation Agreement, Mainstream, Subco and Champagne have
agreed to complete the Transaction pursuant to which, among other things, Subco
and Champagne will amalgamate pursuant to the provisions of the Business
Corporations Act (Ontario) to form a wholly-owned subsidiary of Mainstream
("Amalco"), and each Champagne shareholder (other than a Champagne shareholder
who exercises dissent rights) will be entitled to receive two (2) common share
of Mainstream (each, a "Mainstream Share") for every one (1) common share of
Champagne (a "Champagne Share") held by such Champagne shareholder. As a result,
53,777,454 Mainstream Shares will be issued to former Champagne shareholders, on
a non-diluted basis, to acquire a 100% interest in Champagne. 


Upon completion of the Transaction, each holder of the outstanding 13,802,014
common share purchase warrants (the "Champagne Warrants") of Champagne will
receive two (2) replacement common share purchase warrants of Mainstream, having
the same terms as the Champagne Warrants, as applicable, but shall be
exercisable at a price equal to half the exercise price of the Champagne Warrant
being exchanged. 


In connection with the Transaction, Chris Hopkins will be appointed Chief
Executive Officer and a director of Mainstream. Mr. Hopkins has over 25 years of
experience in financial management, mergers & acquisitions, strategic planning,
investor relations, corporate governance and financial & management reporting
primarily in the mining sector. Champagne's existing geological team will also
continue as part of the newly merged company.


Champagne's principal property is the Goodfish Kirana Property, located 5 km
north of Kirkland Lake, Ontario, which is comprised of contiguous mining claims
covering approximately 3,330 hectares. Further details including a recent
technical report can be found on Champagne's website at
www.champagneresources.com.


Completion of the Transaction will be subject to certain standard conditions
including, without limitation: (a) Mainstream completing a $500,000 financing
prior to closing; (b) all outstanding stock options of Champagne being
terminated prior to closing; (c) receipt of all necessary consents, waivers,
permits, exemptions, orders and approvals, including the approval of the TSX
Venture Exchange (the "TSXV") for the issuance of the Mainstream Shares pursuant
to the Transaction; and (d) receipt of shareholder approval by Champagne
shareholders to the Transaction. The Transaction will not be subject to the
approval of the shareholders of Mainstream.


Neither the TSXV nor its Regulation Services Provider (as that term is defined
in the policies of the TSXV) accepts responsibility for the adequacy or accuracy
of this release and has in no way passed upon the merits of the Transaction and
has neither approved nor disapproved of the contents of this press release. 


Not for distribution to U.S. Newswire Services or for dissemination in the
United States. Any failure to comply with this restriction may constitute a
violation of U.S. Securities laws. 


Completion of the Transaction is subject to a number of conditions including but
not limited to TSXV acceptance and if applicable pursuant to the TSXV
requirements, receipt of approval by Champagne shareholders to the Transaction.
Where applicable, the Transaction cannot close until the required shareholder
approval is obtained. There can be no assurance that the Transaction will be
completed as proposed or at all. 


Investors are cautioned that, except as disclosed in the management information
circular or filing statement to be prepared in connection with the Transaction,
any information released or received with respect to the Transaction may not be
accurate or complete and should not be relied upon.
