Creso Announces Listing on Canadian Securities Exchange

MONTREAL, QUEBEC--(Marketwired - Feb. 18, 2014) -

NOT FOR DISTRIBUTION TO UNITED STATES NEWSWIRE SERVICES OR FOR RELEASE PUBLICATION, DISTRIBUTION OR DISSEMINATION DIRECTLY, OR INDIRECTLY, IN WHOLE OR IN PART, IN OR INTO THE UNITED STATES.

Creso Exploration Inc. ("Creso" or the "Corporation") is pleased to announce that it has obtained final approval for the listing of its common shares on the Canadian Securities Exchange. It is expected that the common shares of Creso will begin trading at the opening of the market on February 19, 2014 under the symbol "CXT".

Creso also announces that a special meeting of shareholders of Creso will be held on February 28, 2014 (the "Special Meeting") to consider and approve the proposed amalgamation transaction with Dundee Sustainable Technologies Inc. (previously known as Nichromet Extraction Inc.) ("Dundee Sustainable") and a wholly-owned subsidiary of Dundee Sustainable ("Subco") pursuant to which Creso and Subco will amalgamate (the "Amalgamation") and the amalgamated company will become a wholly-owned subsidiary of Dundee Sustainable (please see the press releases dated November 14, 2013 and November 25, 2013).

Pursuant to the Amalgamation, Dundee Sustainable would, indirectly, acquire all of the issued and outstanding common shares of Creso which it does not already own, and the shareholders of Creso would receive one subordinate voting share (a "Subordinate Voting Share") of Dundee Sustainable in exchange for two common shares of Creso. Holders of options and warrants of Creso will receive options and warrants, as applicable, of Dundee Sustainable based upon the same exchange ratio.

In order to become effective, the Amalgamation must be approved by a special majority (66 2/3%) of the votes cast at the Special Meeting. In addition, since Dundee Sustainable has multiple voting shares outstanding (held by Dundee Corporation), the Amalgamation must also be approved by a majority of the minority of the shareholders of Creso. In this regard, Creso mailed a management information circular to each shareholder of Creso. The multiple voting shares of Dundee Sustainable will not be listed on any stock exchange and are convertible, at the option of the holder, into Subordinate Voting Shares for no additional consideration.

It is anticipated that the Amalgamation will become effective in March 2014 after the requisite approval of the Amalgamation by Creso shareholders and all other regulatory approvals have been obtained and all other conditions to the Amalgamation have either been satisfied or waived. CSE has conditionally approved the listing of the Subordinated Voting Shares of Dundee Sustainable.

Information for non-resident Creso Shareholders

Due to securities law considerations, Dundee Sustainable will not distribute Subordinate Voting Shares into any non-qualifying jurisdiction, including the United States, or to a Creso Shareholder resident or located in any non-qualifying jurisdiction, including, but not limited to, a U.S. securityholder.

About Dundee Sustainable

Dundee Sustainable is a private Canadian company controlled by Dundee Corporation that has developed patented precious and base metal extraction processes that are environmentally friendly in that the residues of mining operations are totally void of contaminants such as sulfur and arsenic. These new processes are based on chlorination and are particularly efficient for the treatment of polymetallic ores either in the form of sulfides, oxides or arsenides. These chloride based patented processes are a substitute to cyanidation, which is commonly used in the mining industry.

Dundee Sustainable was awarded a $5 million grant by the Government of Canada through Sustainable Development Technology Canada (SDTC) for the development of an innovative patented technology that will increase efficiency in processing gold while reducing the environmental impact and the construction of a demonstration plant of $27 million. The $5 million grant was part of a $61.8 million investment by the Government of Canada to support 23 clean technology projects across Canada.

Dundee Sustainable received a grant of $700,000 from the Québec Ministère du Développement économique, de l'Innovation et de l'Exportation.
