Nuurstei Coking Coal Project
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 currently being evaluated as a near term mine development, producing a washed hard coking coal. Nuurstei is located approximately 10 km from Khuvsgul provincial capital of Moron which has recently been connected to the nearest rail head at Erdenet by a sealed road. Nuurstei is approximately 160 km 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. A 2018 drilling programme has been designed to look to both upgrade and extend the resource base in order to support a mine development based on supplying a 1 Mtpa wash plant on site.
Nuurstei Coal Resource
|BENCH NAME||Indicated (Mt)||Inferred (Mt)||Total|
|BOW – 50 m||1.18||1.5||2.68|
|50 m – 100 m||1.72||2.3||4.02|
|100 m – 150 m||1.1||2.1||3.2|
|150 m – 200 m||0.34||1.7||2.04|
Summary of Indicated and Inferred Coal Resources at 50 m Depth Increments
Work completed during 2014 and 2015 confirmed coal continuity along a 1.8 kilometre strike on a northwest-to-southeast orientation with multiple medium to thin seams coal steeply dipping to the south west. The area is faulted with a number of north-south faults crossing the deposit and exposing surface coal outcrops. In addition, a separate near surface coal deposit to the west of a major fault dips in a separate direction to the north and this will be further investigated in 2018.
2011 – 2015 Exploration drilling
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. The 2018 drilling programme will provide additional core samples for quality and washability testwork which will be fed into the Feasibility Study including wash plant design work.

The Company has also entered into a contract to buy 100,000 tonnes of raw coal from a mine adjacent to the Nuurstei Mining License. The Company intends to mine this coal on behalf of the owner in order to provide commercial quantities of samples and confirm logistics paths and costs.
Nuurstei’s close proximity to existing infrastructure (town, road, rail and services) provides an excellent opportunity to assess the economics of a road based operation, prior to the completion of the Erdenet to Ovoot railway construction, given access to a 420 km paved road from Moron to Erdenet where coal loadout facilities and an existing rail head are located. The Company, subject to a positive feasibility study and funding availability is aiming to be in production Q1 2019.
