ASX ANNOUNCEMENT

US ADR PROGRAM LAUNCHED

Monaro Mining NL (“Monaro”, the “Company” or “MRO”) is pleased to report that the sponsored Level 1 American Depositary Receipts (“ADR”) facility was successfully launched on Wednesday 25 June 2008. Monaro shares are eligible for Over-The-Counter (OTC) trading in the United States of America on the NASDAQ Stock Market in the form of American Depositary Shares (ADS) under the symbol “MNOMY”. Monaro continues its listings on the Australian Securities Exchange under the symbol “MRO” and on the Frankfurt Stock Exchange under the symbol “M2H”.

Deposits of underlying shares of Monaro are being accepted for the issuance of ADSs with each ten (10) MRO shares constituting (or being the equivalent of) one (1) ADS. The depositary bank for the ADSs is JPMorgan Chase Bank, N.A. (“JPMorgan”). Investors wishing to receive ADSs will need to deposit the appropriate number of MRO Shares with the depositary bank's custodian in Australia prior to receiving delivery of the corresponding ADSs from the depositary bank, subject to the terms and conditions of, including without limitation, payment of certain fees, costs and expenses set forth in the deposit agreement for the ADSs.

The establishment of the Monaro ADR program and the ability to trade the Monaro shares in the form of ADSs on the OTC market in the United States of America are important steps in the growth of Monaro in its strategy to become a significant international uranium company.

With the upcoming merger with Uranium King Limited near finalised, Monaro will be well placed to develop a significant market profile in the North American capital market. It remains Monaro’s intention to seek a Level 2 ADR listing later this year, including an application for the ADRs to be traded on the American Stock Exchange.

Monaro provides the opportunity to listen to an audio broadcast with Warwick Grigor, Chairman of MRO discussing the Level 1 ADR program live at 2.30pm on Tuesday 1 July 2008.

KEY INFORMATION

What is an American Depositary Receipt (ADR)?

'ADR' is the acronym for American Depositary Receipts. An ADR is a negotiable U.S. security representing ownership of publicly traded shares in a non-U.S. corporation. ADRs are a common way for investors to buy equity in non-US companies without having to worry about the details of cross-border transactions. ADRs are priced in US dollars, pay dividends in US dollars and can be traded just like shares of US companies. ADRs are issued by a US commercial bank (in the case of Monaro by JPMorgan) and represent a fixed number of foreign registered shares, depending on the ratio of ADRs to ordinary shares.

Benefits to an Investor

ADRs offer a simple convenient alternative for investing internationally. For US investors, ADRs eliminate many of the obstacles of holding non-US securities since they trade and settle according to US market practices, are quoted and traded in US dollars, eliminating the need for currency conversions and pay dividends in US dollars. They eliminate custodian safekeeping charges in the issuer‘s home country.

Who is Monaro’s ADR depositary bank and transfer agent?

JPMorgan is the depositary bank and transfer agent for Monaro‘s ADRs. Monaro’s ADRs are backed by registered shares held under custody in Australia in JPMorgan's name on behalf of Monaro‘s ADR holders. As the depositary bank, JPMorgan performs the roles of registrar, transfer agent and record keeper.

How to Convert Foreign Shares into ADRs and Vice Versa

Investors can transfer their foreign shares to JPMorgan's custodian bank in the issuer's home country. Upon receipt of the foreign shares, JPMorgan will issue ADRs to the investor, representing the newly deposited shares. To convert the ADRs back into foreign shares, the investor will be required to instruct their broker to cancel the ADRs, and provide him or her with complete delivery instructions in the issuer's home country.
