The company said that the total coal resources include 6,680 million tonnes inferred resources and 2,365 million tonnes indicated resources.

The coal resources are based on drilling results from recently completed exploration boreholes, which have a suite of down-hole geophysical logs. The drilling program comprised 150 boreholes totaling 50,000mt, with coal quality data derived from laboratory analyses of coal cores from 50 boreholes with a minimum of 95% core recovery.

Riversdale is in discussions with a number of steel makers in Asia, Europe and South America regarding coal sampling and the future marketing of coal products. These products are expected to comprise quality hard coking coal and a secondary thermal coal product, consisting of thermal coal suitable for both the Indian and African markets.

Michael O’Keeffe, executive chairman of Riversdale, said: “The Zambeze Project is another tier one coal project for Riversdale Mining in Mozambique. The upgrade of total coal resources to over 9.0 billion tonnes confirms the Moatize basin’s status as a coal province of global significance. Total coal resources under management by Riversdale in Mozambique now amount to 13 billion tonnes.”
