TORONTO, ONTARIO--(Marketwired - Aug. 7, 2013) -

NOT FOR DISSEMINATION IN THE UNITED STATES OR THROUGH U.S NEWSWIRE SERVICES

Rockex Mining Corporation ("Rockex" or the "Corporation") (TSX:RXM) is pleased to announce a proposed non-brokered private placement (the "Private Placement") of units (each a "Unit") at $0.055 per Unit. The Corporation proposes to issue up to 7,181,818 Units to accredited investors for aggregate gross proceeds of up to $395,000. Each Unit will be comprised of one common share of the Corporation (each a "Common Share") and one (1) transferable warrant of the Corporation (each a "Warrant"), with each Warrant entitling the holder to purchase one Common Share at a price of $0.10 per share at any time within 36 months after the issuance of the Units.

The following directors of the Corporation (collectively, the "Insiders") propose to participate to the Private Placement for an aggregate of 900,000 Units representing 2.98% of the Corporation's issued and outstanding Common Shares on a partly diluted basis:

Following completion on April 17, 2013 of the first tranche of a private placement of units (the "Initial Private Placement") (see the Corporation's news release dated April 17, 2013), an aggregate of 4,828,371 units were issued with a total of 2,778,371 units issued to the following insiders of the Corporation (the "Initial Insiders") representing 10% of the issued and outstanding Common Shares as of April 16, 2013, on a partly diluted basis:

Following completion of the Private Placement, insiders of the Corporation will have participated in both the Initial Private Placement and the Private Placement by purchasing an aggregate of 3,678,371 Units representing 13.24% of the issued and outstanding Common Shares as of April 16, 2013, on a partly diluted basis.

The Private Placement is subject to the approval of the Toronto Stock Exchange (the "TSX") and, because the Private Placement will provide the issuance of Common Shares to insiders of the Corporation of greater than 10% of the number of Common Shares which were issued and outstanding as of April 16, 2013, the rules of the TSX require that the Corporation obtain approval of the Private Placement from the holders of a majority of the voting shares of the Corporation, excluding the votes attached to the Common Shares held by the Initial Insiders and the Insiders, their respective associates and affiliates and any other insiders that may subscribe for Units under the Private Placement. However, the rules of the TSX also provide that such approval may be obtained in writing from shareholders without the requirement to convene a shareholders' meeting for such purposes.

The Closing of the Private Placement will occur as soon as the applicable closing conditions, including the TSX approval, have been satisfied, but in no event earlier than August 15, 2013.

The gross proceeds received by the Corporation from the sale of the Units will be used by the Corporation principally for the costs of a preliminary economic analysis, metallurgical tests and costs and fees associated with this Private Placement, and any surplus funds for general corporate overhead expenses.

In connection with the Private Placement, Rockex will pay finder's fees to persons qualified under applicable securities legislation to receive finder's fees at a rate of 8% in cash, for a total of up to $31,600, and 10% in non-transferable finder warrants, for a total of up to 718,181 finder warrants (each finder warrant entitling the finder to purchase one Common Share for $0.10 within 24 months after closing).

All of the securities to be issued pursuant to this Private Placement will be subject to a four (4) month hold period.

This news release is not an offer of securities for sale in the United States. The securities have not been and will not be registered under the U.S. Securities Act of 1933, as amended, and may not be offered or sold in the United States absent registration or an applicable exemption from registration. This press release shall not constitute an offer to sell or solicitation of an offer to buy nor shall there be any sale of the above described securities in any jurisdiction in which such offer, solicitation or sale would be unlawful.
