MacDonald Mines Exploration Ltd. (TSX-V: BMK) ("MacDonald Mines", "MacDonald" or the "Company") announces that, due to continued investor demand, it is increasing the size of its non-brokered private placement offering to $4,250,000 consisting of: (i) "charity flow-through" Units at a price of $0.135 each (the "Charity FT Unit Offering") and (ii) "flow-through" Units at a price of $0.10 each (the "FT Unit Offering" and, together with the Charity FT Unit Offering, the "Offering"). Eventus Capital Corp. has been appointed as a finder in connection with the Offering.

Each Unit will be comprised of one Common Share and one-half of one Common Share purchase warrant (each whole warrant, "Warrant"). Each Warrant shall be exercisable to acquire one Common Share ("Warrant Share") at a price of $0.20 per Warrant Share for a period of 24 months from the closing of the Offering. If the closing price of the Common Shares is at a price equal to or greater than $0.35 for a period of 10 consecutive trading days, MacDonald will have the right to accelerate the expiry date of the warrants by giving notice, via a new release, to the holders of the Warrants that the Warrants will expire on the date that is 30 days after the issuance of said news release.

Common Shares issued under the FT Offering and Charity FT Unit Offering qualify as 'flow through shares' ("Flow Through Shares"). The gross proceeds from the FT Offering and Charity FT Unit Offering will be used to incur 'Canadian exploration expenses' that will qualify as 'flow through mining expenditures' as those terms are defined in the Income Tax Act which will be renounced to the initial purchasers of the Flow Through Shares.

Finders will receive a 7% cash payment and that number of compensation warrants (having the terms described above) equal to 7% of the Units sold. Closing of the Offering is subject to approval of the TSX Venture Exchange. Securities issued in the Offering are subject to a statutory hold period of four months.

This news release does not constitute an offer to sell or a solicitation of an offer to buy any of the securities in the United States of America. The securities have not been and will not be registered under the United States Securities Act of 1933, as amended, (the "U.S. Securities Act") or any state securities laws and may not be offered or sold within the United States or to U.S. Persons (as defined in the U.S. Securities Act) unless registered under the U.S. Securities Act and applicable state securities laws, or an exemption from such registration requirement is available
