Darnley Bay Resources Announces Memorandum of Understanding ("MOU") With Diadem Resources

TORONTO, ONTARIO--(Marketwire - Oct. 4, 2011) - Darnley Bay Resources Limited (TSX VENTURE:DBL) has signed an MOU with Diadem Resources Ltd. (TSX VENTURE:DRL) for Diadem to acquire DBL's 50% interest in the Franklin Diamond Project on the Parry Peninsula and its 50% diamond interest in the South Lands. DBL retains its 100% interest to all other minerals on the South Lands. As consideration, Diadem will issue DBL 11,700,000 common shares and a 2% diamond royalty. In addition, Diadem shall undertake at least $1,250,000 of diamond exploration work on the Parry Peninsula and/or South Lands by September 30, 2012 (see reference map at www.darnleybay.com).

DBL shall retain the right to restore its rights in the subject areas if valuable minerals are discovered on the lands by paying in cash to Diadem, 200% of Diadem's aggregate expenditure on the subject lands incurred prior to the exercise of the repurchase. Diadem will retain the right to purchase 1% of the diamond royalty for a $1.5 million payment to DBL.

DBL CEO Jay Richardson said, "We believe this transaction will result in a simplification that will enable Diadem to utilize its significant diamond exploration expertise to maximum advantage. DBL would continue to be the beneficiary of Diadem's success through its back-in rights and, without further cost, through its shareholding and NSR. We will continue to emphasize exploration for other minerals on all of our lands."
