Dear Sir/Madam

CONFIDENTIALITY AGREEMENT WITH CONSOLIDATED MINERALS LIMITED

The Board of OM Holdings Limited (“OMH”) wishes to advise that OMH has executed a Confidentiality Agreement with Consolidated Minerals Limited (“ConsMin”) with respect to investigating a possible transaction involving ConsMin’s Woodie Woodie manganese operation (“Woodie Woodie”), which is located in the Pilbara region of Western Australia.

ConsMin currently holds an 11.7% interest in OMH through its wholly owned subsidiary Stratford Sun Limited.

ConsMin and OMH are investigating a possible acquisition of an interest in Woodie Woodie by OMH to effect a business combination involving the companies’ respective Australian manganese operations and to determine whether any potential strategic, operating and/or marketing synergies could be achieved as a result of such a transaction, which could create the world’s second largest low phosphorous siliceous high grade manganese ore producer.

In accordance with the Confidentiality Agreement, OMH will commence a staged due diligence investigation (“DDI”) on Woodie Woodie with the initial phase providing OMH access to information on Woodie Woodie equivalent to that publicly available on OMH.

Subsequent more detailed DDI may occur on Woodie Woodie and will be conditional upon yet to be negotiated agreeable valuations and structuring of any consideration associated with such a proposal, whether in the form of equity, cash or debt (or a combination thereof). Access to OMH information for due diligence investigations by ConsMin may occur in the future, subject to agreement on valuation and consideration structure.

As is the case with any strategic opportunity subject to preliminary assessment and evaluation by OMH, the proposal requires extensive examination to understand if benefits can be derived for OMH stakeholders, whether terms which are acceptable to both OMH and ConsMin can be agreed and there is no guarantee that any transaction will eventuate.

OMH expects to commence the initial phase of the DDI process on Woodie Woodie as soon as is practical and will keep the market informed with regards to any material developments should they arise.

Yours faithfully OM HOLDINGS LIMITED

BACKGROUND PROFILE OF OM HOLDINGS LIMITED

OMH listed on the ASX in March 1998 and has its foundations in metals trading – incorporating the sourcing and distribution of manganese ore products and subsequently in processing ores into ferro-manganese intermediate products. The OMH Group now operates commercial mining operations – leading to a fully integrated operation covering Australia, China and Singapore.

Through its wholly owned subsidiary, OM (Manganese) Ltd, OMH controls 100% of the Bootu Creek Manganese Mine (“Bootu Creek”) located 110 km north of Tennant Creek in the Northern Territory.

Through its Singapore based commodity trading activities, OMH has established itself as a significant manganese supplier to the Chinese market. Product from Bootu Creek has strengthened OMH’s position in this market.
