Mainstream Provides Notice of Default

TORONTO, ONTARIO--(Marketwired - April 7, 2015) - Mainstream Minerals Corporation (TSX VENTURE:MJO) (the "Company") announces that it is late in filing its annual financial statements and management discussion and analysis ("MD&A") for the year ended November 30, 2014 on the prescribed deadline of March 30, 2015.

The Company has made an application with the applicable securities regulators under National Policy 12-203 - Cease Trade Orders for Continuous Disclosure Defaults ("NP 12-203") requesting that a management cease trade order be imposed in respect of this late filing rather than an issuer cease trade order, but there is no assurance that it will be granted. The issuance of a management cease trade order generally does not affect the ability of persons who have not been directors, officers or insiders of the Company to trade in their securities.

The Company has been unable to complete the required filings due to a lack of capital to complete its audit. As a result, the Company requires additional time to raise sufficient capital to complete its annual financial statements, MD&A and audit.

The Company has contacted various lenders and is in discussions with a potential purchaser in connection with a proposed asset purchase transaction involving the Company. The Company anticipates that it will be able to secure sufficient funding from lenders to prepare and file the annual financial statements and MD&A on or prior to May 31, 2015.

The Company confirms that it will satisfy the provisions of the alternative information guidelines under NP 12-203 by issuing bi-weekly default status reports in the form of news releases for so long as it remains in default of the filing requirements to file its financial statements and MD&A within the prescribed period of time. The Company confirms that there is no other material information relating to its affairs that has not been generally disclosed.

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.
