but what do we know about the coal that is there? What is the quality really? Bugger all is actually disclosed. Section 5.1.3 and 5.3.6 of the black coal reporting guidelines are hints at what should be reported for a coking coal Resource. Has any coking test work such as CSR, CRI, Gray King, G&Y index been carried out? if so what are the results? How many tests , where from. Why does the trend in quality shown in Resource plots stop at "premium coal" and not keep trending? Far too many questions far too few answers.
5.1.3 For example, reporting a Coal Resource of coking quality requires that coking coal test work has been undertaken. It should be established that there is sufficient confidence that the stated product can be produced, as it would be misleading to report such a product type without suitable evidence. In the same way it is necessary to establish sufficient confidence in the physical parameters (e.g. thickness, dip, faulting) of the coal seam which may be subject to greater sensitivity than the quality.
5.3.6 If metallurgical coal products are proposed to be marketed from the deposit, additional parameters need to be analysed, including coal rank (such as vitrinite reflectance and ultimate analysis), coal petrography, coking properties, phosphorous and critical trace elements. If hard coking coal is considered to be part of the product mix, the results of coke strength tests must support such a conclusion.
