TUCSON, Arizona., February 21, 2007- Mr. Ronald Hirsch, Chairman of the board of Directors of Nord Resources Corporation ("Nord") (Other OTC: NRDS.PK - News) announced today that Platinum Diversified Mining, Inc. (“Platinum”) has failed to pay the $2,000,000 termination fee demanded by Nord in connection with the termination of the Merger Agreement respecting the proposed acquisition of Nord by Platinum (the “Merger”). In its Notice of Termination dated February 15, 2007, Nord demanded payment of the termination fee no later than the close of business on Tuesday, February 20, 2007, and placed Platinum on notice that it has reserved all of its rights to pursue Platinum for damages.
