MONTREAL, QUEBEC--(Marketwire - June 17, 2010) - Diadem Resources Ltd. (the "Company") (TSX VENTURE:DRL) is pleased to announce that it has received the decision letter from the Environmental Impact Screening Committee (EISC) for the Inuvialuit Settlement Region, recommending to the relevant permitting agencies that the Company be allowed to proceed with its proposed program for drilling and exploration for metals and diamonds on its currently held mineral properties for the 2010 to 2012 period.

The Company presented its program to the EISC on June 3, and the committee received input from seven Inuvialuit, territorial and federal agencies for its evaluation. The Company is now awaiting the following permits prior to commencing its drilling program:

• Inuvialuit Land Administration – Land Use Permit
• Environment and Natural Resources, Government of the Northwest Territories – Wildlife Research Permit
• Aurora Research Institute – Scientific Research Permit.

The Company expects these permits to be issued in the near future.

During the period May 26 to June 11, 2010, Company personnel and consultants visited Paulatuk, Inuvik, Aklavik and Yellowknife to meet with a number of agencies and service providers to present the plans for the remainder of this year's exploration campaign, and additional drilling in 2011 and 2012.

The Company plans to begin mobilizing the drill camp, personnel, drilling equipment and field equipment to the property as soon as the permits are issued and the funding completed.

Furthermore, the Company is pleased to confirm that it has repaid all outstanding debts relating to its 2008 drilling program. These debts were paid through discounts varying between 25% and 50% of their initial amount by way of either cash or the Company's treasury shares (or a combination of the two). TSX Venture approval of same is being applied for.

The Company is presently under discussion with Darnley Bay Resources Limited, its partner in the Darnley Bay Penninsula. In order to reduce both parties' expenses, it is proposed to have a joint field camp and drilling contract.

The Company currently has outstanding 38,399,194 common shares. On a fully-diluted basis, the Company has 60,953,741 common shares outstanding.
