INFORMATION MEMORANDUM

INTRODUCTION

This Information Memorandum has been prepared for the information of members of Monaro Mining NL (“Monaro” or “Company”) in connection with the business to be conducted at the Annual General Meeting of members to be held at The Portside Conference Centre, Symantec House, Level 5, 207 Kent Street, Sydney NSW 2000 on Wednesday 28 November 2007 at 11.00 am EST.

This Information Memorandum should be read in conjunction with the accompanying Notice of Meeting. The purpose of the Information Memorandum is to provide shareholders with information that the Board believes to be material to shareholders in deciding whether or not to approve the above resolutions.

TO RECEIVE FINANCIAL REPORT

The fi rst agenda item in the notice of meeting deals with a procedural matter, namely to receive the Financial Report for the Company for the year ended 30 June 2007.

RESOLUTION ONE: RE-ELECTION OF DIRECTOR – MR WARWICK GRIGOR

Mr Warwick Grigor, the Chairman of the Company, retires as a director by rotation in accordance with the Company’s constitution and submits himself for re-election.

The other directors of the Company consider Mr Grigor to be a valuable member of the Board and recommend that shareholders vote to re-elect Mr Grigor.

RESOLUTION TWO: ELECTION OF DIRECTOR – MR MALCOLM JAMES B.Bus, CPA, FAICD, MAusIMM

Following the resignation of Mr Michael Evans as a director of the Company, the Board of Directors appointed Mr Malcolm James as a director.

In accordance with the ASX Listing Rules and Regulation 11.6 of the Company’s Constitution, Mr James holds offi ce only until next members meeting (ie in this case the Annual General Meeting) and is eligible for re-election by the shareholders.

As indicated in the next paragraph Mr James brings valuable expertise to the Board of Directors and the other directors recommend that shareholders vote to re-elect Mr Jones.

Mr James is a business graduate of RMIT University in Melbourne, Australia with over 25 years experience in merchant banking, engineering, manufacturing and fi nancing. Over the last 15 years he has played an active role in the identifying, exploring, fi nancing and developing a number of signifi cant natural resource projects in Australia, the former Soviet Union, the Middle East, Africa and Asia.

Mr James is Chairman of the Australian Securities Exchange listed companies Peninsula Minerals Limited and Lefroy Resources Ltd. Mr James is also a director of two AIM listed companies namely Summit Resources Plc and Cue Energy Plc.

RESOLUTION THREE: ADOPTION OF REMUNERATION REPORT

Pursuant to section 250R(2) of the Corporations Act the Company is required to put the Remuneration Report to the vote of Shareholders. The Annual Report for the year ended 30 June 2007 contains a Remuneration Report which sets out the remuneration policy for the Company and reports the remuneration arrangements in place for the Directors and other key management personnel.

The provisions of the Corporations Act provide that the vote is only an advisory vote of Shareholders. Resolution Three is, therefore, advisory only and does not bind the Directors of the Company. Of itself, a failure of Shareholders to pass Resolution Three will not require the Directors to alter any of the arrangements in the Remuneration Report; however the Board will take the outcome of the vote into consideration when considering the future remuneration policy.

RESOLUTION FOUR: APPOINTMENT OF AUDITOR

During the fi rst half of 2007 the Company made a policy decision to relocate its administration offi ces from Perth to Sydney. As a consequence of this, the current auditor of the Company, Stantons International, who are based in Perth have indicated their intention to resign as auditor and Grant Thornton NSW, who have offi ces in Sydney have agreed to act as Auditor. In accordance with the Corporations Act, Stantons International have made application to ASIC for permission to resign as auditor.

In accordance with section 328B of the Corporations Act, accompanying this notice of meeting is a copy of a nomination by a shareholder in the Company of Grant Thornton NSW as auditor of the Company.
