Initial exploration suggests the coal target could be as large as 340 to 615 million tonnes.Before making the announcement, basalt mining machinery and working principle for sale in chinathe company was placed into a trading halt on Monday. Drilling indicates thermal coal intersections varying in thickness from 12 metres to 65 metres recorded in eight aircore drill holes along a seven kilometre strike, four of which ended in coal. The discovery lies beneath soft overburden ranging from 32 metres to 73 metres in thickness.Engaging independent coal consultant Xenith, preliminary analysis suggests the resource is a low-rank thermal coal, similar to that mined in Indonesia and currently exported to India and China. The company said it will remain focussed on gold but plans to develop its coal assets via a joint venture, 50 tph iron ore beneficiation plant in russiain-specie distribution of shares in a separate company or possibly put the find up for sale. “Northern Star has begun studying ways to optimise this discovery without changing its focus from gold,” the company said. “Initial analysis shows the coal would be suitable for fuelling a major base-load power station and may also be amenable for a coal-to-liquids project which could supply diesel to the Pilbara.” Follow-up drilling has already commenced with results due in the March quarter of 2014.The bulk of the exploration work completed to date has been on tenements that are 100 per cent owned by Northern Star.But the company said there is a potential for the seam to run onto tenements held by Fortescue Metals Group. “These tenements are subject to a joint venture agreement under which Northern Star can earn up to 60 per cent of the non-iron ore rights,” the company said. “By having a relentless focus on productivity, bentonite processing plant manufacturers mining equipment for salewhich has increased 100 per cent in the past 18 months, and making financial performance our top priority, we have been able to generate strong results across all the key areas of exploration, production and cash flow,” he said.
