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.

Bootu Creek has a design capacity of 600,000 to 650,000 tonnes of manganese product annually. Bootu Creek has further exploration potential given that its tenement holdings extend over 2,872 km[2] .

Bootu Creek’s manganese product is exclusively marketed by the OMH Group’s own trading division with a proportion of the product consumed by the OMH Group’s whollyowned Qinzhou smelter located in south west China.

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.

OMH also holds a 11% shareholding in Territory Resources Ltd, a company presently operating the Frances Creek iron ore project in the Northern Territory.
