Modun Resources says testing of coal briquettes from its Nuurst project site has led to a significant increase in coal energy. Earlier raw coal samples had measured 4178 kcal/kg compared to the most recent test confirming a calorific value of 5648 kcal/kg.

The company says these test results confirm Nuurst coal reaches the benchmark 5500 kcal/kilogram Newcastle thermal coal energy level.

Modun’s managing director Rick Dalton says, “We are very excited about these test results and our ability to achieve significant improvements in coal quality via a very cost-effective beneficiation process. The Nuurst coal briquettes bring our coal up to the Newcastle thermal coal energy benchmark, ensuring a far more efficient burning coal.

“These results are significant as we seek to work with the Mongolian Government to develop a low cost, high energy and low emission coal to help improve air quality in Ulaanbaatar. Nuurst briquettes have the potential to be of great assistance in helping the Mongolian Government achieve their targets for pollution reduction and we remain positive about the ongoing discussions we are having with the Government in relation to its clean coal initiatives,” he says.

The Nuurst briquettes were created in Australia using a binderless process which crushes the raw coal and uses hot gas to dry the coal to extract the moisture. The coal is then pressed into briquettes.

The 489 million tonne JORC-compliant Nuurst resource is in central Mongolia, about 120km south of Ulaanbaatar. It takes in a 34.5sqkm area about 600km from the China border, and 6km from existing rail infrastructure.

A program to verify previous assay work and the inherent moisture content of the coal at Nuurst began in 2012 after the company realized the moisture content was incorrectly calculated from the 2011 drill program assays.
