CONFIRMATION OF US LISTING – ADR PROGRAM

Monaro Mining NL (“Monaro” and/or the “Company”) is pleased to announce that it has satisfied the requirements for Level 1 US listing on the American Stock Exchange and will commence trading on Wednesday 25 June 2008 on NASDAQ under the symbol “MNOMY”. It maintains its listings on the Australian Securities Exchange under the symbol “MRO” and Frankfurt Stock Exchange under the symbol “M2H”.

Monaro is also pleased to announce the launch of a sponsored American Depositary Receipt (“ADR”) facility. Deposits of underlying shares of Monaro are being accepted for the issuance of ADRs with each ten (10) MRO Shares constituting (or be the equivalent of) one (1) ADR. The depositary bank for the ADR's will be JP Morgan Chase. Investors wishing to receive ADR's will need to deposit the appropriate number of MRO Shares with the depositary bank's custodian in Australia prior to receiving delivery of certified ADR's from the depositary bank, subject to the terms and conditions, including without limitation, payment of certain fees, costs and expenses set forth in the applicable deposit agreement among MRO, JP Morgan Chase and the holders of the ADR's.

The Level 1 listing and the associated ADR program are important steps in the growth of Monaro Mining in its strategy to become a significant international uranium company. The increased marketability of its shares is expected to enhance its capital raising ability in both Australia and North America, through increased exposure to investors. In particular, it sees significant synergy with these initiatives and the impending merger with Uranium King Limited.

It is noteworthy that in both the general meetings requisitioned by Monaro Mining NL and Uranium King Limited there was unanimous approval from shareholders of both companies for the merger. It is pleasing to receive such comprehensive support for the initiative.

The Merged Entity will be well placed to create a significant market profile in the North American capital market. The Merged Entity will have the increased capacity to identify and target project and corporate acquisition opportunities. In addition, with the ADR listing in the United States and via its current listing in Europe on the Frankfurt Stock Exchange, the Merged Entity will have increased ability to raise capital.
