Mercator Announces Heads of Agreement
for Sale of New Mexico Copper Company Inc

London 16 March 2010: Mercator Gold plc is pleased to announce that it has entered into a binding heads of agreement (“the Heads of Agreement”) with respect to the sale (“the Transaction”) of its entire interest in New Mexico Copper Company Inc (“NMCC”), the New Mexico, USA corporation solely owned by Mercator that holds an exclusive option over the Copper Flat copper-gold-molybdenum-silver project in New Mexico (“Copper Flat”), to THEMAC Resources Group Ltd (“THEMAC Resources”), a company listed on the TSX Venture Exchange (ticker: MAC.H).

Once the Transaction has completed, it is the intention of THEMAC Resources to exercise NMCC’s option over Copper Flat and to progress the project to production through all necessary feasibility, financing and permitting steps.

Highlights

• Mercator is to receive consideration of 10.5 million fully paid shares in THEMAC Resources and 10.5 million warrants valid for five years and exercisable on a one for one basis at C$0.28 per share.
• The closing price of shares in THEMAC Resources on 12 March 2010 was C$0.24 and there are currently 12,634,705 shares in issue (18,128,816 fully diluted).
• THEMAC Resources is to fund or reimburse all expenditure by Mercator and/or NMCC in relation to the Copper Flat project from the date of the Heads of Agreement until the completion of the Transaction, including any payments to exercise NMCC’s option over Copper Flat that fall due.
• The board of directors of THEMAC Resources is to be composed of five persons: two nominated by Mercator; two members of the current board; and one other person to be mutually agreed.
• THEMAC Resources is to place 5.5 million shares at C$0.15 per share, with attached warrants valid for one year and exercisable on a one for one basis at C$0.28 per share, with Mercator and/or Mercator’s nominees (“the Initial Placing”).
• A second placing (“the Second Placing”) of shares sufficient to raise C$5 million at a minimum placing price of C$0.50 per share, with attached warrants valid for one year and exercisable on a one for one basis at a price sufficient to raise C$10 million should all the warrants be exercised, is to be undertaken by THEMAC Resources prior to completion of the Transaction.
• Exercise of the warrants issued in the Second Placing is to be compulsory if the closing price of shares in THEMAC Resources exceeds the exercise price of the warrants by 50% or more for more than fifteen consecutive trading days.

Patrick Harford, Managing Director of Mercator Gold plc, comments:

“The Copper Flat project is an exceptionally promising asset in the present copper market, and vending New Mexico Copper Company Inc and its exclusive option over the project into a dedicated North American listed company with highly capable and experienced management will ensure that the project becomes well placed to obtain the funding required for the timely recommencement of production.

As a result of the Transaction Mercator will no longer be responsible for the purchase and development costs of the Copper Flat project but will retain a very substantial interest in the project’s future development.

We believe that Mercator’s interest in THEMAC Resources will have the potential to generate extraordinary returns for the Company and its shareholders.

The Transaction is also another example of Mercator’s ability to add significant value to an asset before crystallising that value.”
