Increased coal resources at Hunter Valley Southern Arc Minerals and PT Genesis

first_imgThe latest issue of International Mining Project News, out today, has reports on 16 prefeasibility studies, 4 feasibility studies, 18 projects in development, four new mines that have gone into production, six existing mines that are expanding, seven merger and acquisition announcements and many new appointments to new positions. The report covers 36 gold projects, 15 copper, 12 silver projects, 9 iron ore, seven coal projects, four uranium, rare earths, and zinc projects, three tungsten and nickel projects, two projects on graphite, molybdenum, lithium, diamonds and lead, and one project each on anorthosite, manganese, cobalt, sulphur, niobium, tin, potash, vanadium, titanium, phosphate, mineral sands, ferro alloys and PGMs. Contact [email protected] for a trial.Rio Tinto Coal Australia has declared a significant increase of its managed thermal coal reserves and resources in the Hunter Valley of New South Wales, Australia, compared to the previous estimates reported in Rio Tinto’s 2013 Annual Report. The ore reserve has increased by 546 Mt from 1,331 Mt to 1,877 Mt.Rio Tinto Coal Australia Managing Director Chris Salisbury said “The coal assets managed by Coal & Allied in the Hunter Valley are truly world class and offer a large, contiguous footprint within the most attractive sections of the coal district”.“An extensive drilling program over many decades means we have high confidence in our increased understanding of our coal assets and their quality, which is characterised by shallow, thick seams with little geological faulting. This discovery of greater coal reserves and resources is the result of more than a year’s work and forms part of our wider efforts to deliver greater value to our shareholders. We continue to examine our asset base for further opportunities. Our extensive reserve and resource base, further amplified by this latest announcement, provides many options to sustain and grow our business in the Hunter Valley for many decades to come.”Southern Arc Minerals has announced that it has entered into a binding Memorandum of Agreement with PT Genesis Sumber Energi to form a joint venture to advance the West Lombok project. Under the terms of the Agreement, PT GSE can earn a 25% interest in the West Lombok project by funding and obtaining Government approval of an environmental impact study and feasibility study for small-scale underground gold mines and processing plants on the property. PT GSE must also obtain Government approval to convert the West Lombok exploration permit into an exploitation permit, thereby securing tenure on the property for a further 20 years with the option to extend.South Boulder Mines has commenced pilot testing of the Colluli process design at the Saskatchewan Research Council in Saskatoon, Canada. The testing is being conducted under the supervision of Global Potash Solutions. This work follows prefeasibility design testwork, which was done as bench scale testing.The pilot plant will provide the following critical information:1. Confirmation of the potassium sulphate (SOP) tonnes per seawater tonne2. Confirmation of decomposition kinetics3. Confirmation of precipitation kinetics and retention time4. Enhancement of particle size5. Samples for marketingImportantly, the pilot plant will use potassium bearing salts from the Colluli resource. Samples were dispatched to the test facility and preparation for pilot plant testing has been completed.South Boulder Managing Director, Paul Donaldson, said: “We are pleased that we have been able to develop the test program and commence its execution well ahead of the pre-feasibility study completion. This will allow a seamless integration of the pilot plant data with the definitive feasibility study design and final costings.“Given the process is relatively simple, and commercially proven, the pilot plant is simply an exercise to ensure all of the plant equipment is correctly sized for the final process.”last_img read more
