Nuurstei Coking Coal (90%)

In August 2017 the Company exercised its option, acquiring a further 45% interest in the Nuurstei Coking Coal Project taking its total interest to 90%.

The Nuurstei project is capable of  producing a high quality washed hard coking coal. Nuurstei is located approximately 10 km from Khuvsgul provincial capital of Moron and is approximately 160 km north east of the Ovoot project.

In October 2017 the Company received a mining license covering the Nuurstei resource area.

Previous drilling has identified modest JORC Coal Resources of 4.7 Mt of Indicated and 8.1 Mt of Inferred. 

Further work on Nuurstei has been deferred with the focus being on bringing into production the much larger Ovoot Coking Coal Project.

Summary of Indicated and Inferred Coal Resources at 50 m Depth Increments

Coal quality analysis results including washability and coking testwork was completed as part of the 2014 and 2015 exploration programmes. Analysis was conducted on core samples from these programmes and indicates a quality hard coking coal present at Nuurstei, with a high caking “G” index, good fluidity and low sulphur.
