MONTREAL, QUEBEC--(Marketwire - July 9, 2010) - Diadem Resources Ltd. (TSX VENTURE:DRL)

Diadem Resources Ltd. ("Diadem") and Darnley Bay Resources Limited ("Darnley Bay") (TSX VENTURE:DBL) and are pleased to announce that they have agreed on the principal terms of a 50/50 joint venture agreement for exploration and production of diamonds and minerals on the Parry Peninsula, Northwest Territories. The agreement represents a renewed commitment by the companies to locate a diamond mine in the region.

The property currently encompasses 33 mineral claims. These claims are located on Inuvialuit 7(1)(b) lands northwest of Paulatuk NT. Work on these claims is subject to a cooperation agreement between the Inuvialuit Regional Corporation and the joint venture, and all other terms and conditions for development on Inuvialuit lands.

The terms of the agreement include the following:

• The joint venture will be co-managed by the two companies;
• Diadem will be responsible for the first $2 million in exploration expenditures, with $1 million to be recovered directly by Diadem from Darnley Bay's share of the eventual diamond production of the joint venture; and
• Diadem has a 180-day option to extend the joint venture to include diamond exploration and production on ten prospecting permits currently held by Darnley Bay south and southwest of Paulatuk, where the two companies previously explored for diamonds, upon payment of certain fees and expenditures to Darnley Bay.

Darnley Bay has received all necessary permits to carry out exploration and drilling on the properties in the Paulatuk region (see Darnley Bay's news release of June 28, 2010). The joint venture's drilling and exploration plans were included in the permitting process, and therefore work may proceed immediately. In 2000, Darnley Bay located ten kimberlite pipes within the Parry Peninsula claim group, of which six proved diamondiferous. Subsequent to these initial discoveries a total of 38 kimberlitic targets, including the original ten kimberlites, were identified and prioritized for detailed study. The two companies are completing a review of the exploration data, including prior drilling, indicator mineral sampling, airborne and ground geophysics, to prioritize the new kimberlite pipe targets for drilling and determine which known pipes require further drill assessment.

Darnley Bay personnel Stephen Reford and Don Yamkowy, and Diadem personnel Aimé Bertrand and Ed Schiller, visited Paulatuk and Inuvik in late May-early June, 2010 to lay the groundwork for the upcoming drill program. Aurora Geosciences, under project manager Lou Covello, has commenced Darnley Bay's metals exploration south of Paulatuk. The program will be expanded to incorporate the Parry Peninsula work, taking advantage of synergies so that costs are reduced and a greater proportion of each company's budget is applied to drilling.

About Diadem Resources Ltd.

Management of Diadem is focused on acquiring near-production mining opportunities in North America, especially those related to diamonds and gold. Its principal current activity is diamond exploration in the Franklin Bay area of the Northwest Territories. On that project Diadem now has identified 28 potential drill targets on the Parry Peninsula, which currently constitutes the Franklin Bay project area. A ground magnetic survey has just been completed and the results are being analyzed. When the analysis is complete, Diadem expects to finalize its drilling program (which is subject to permitting).
