Thor Mining set for further fire assays at Spring Hill

By BFN News | 07:59 AM | Tuesday 14 January, 2014

Thor Mining said upgraded gold assays from the Spring Hill, south of Darwin in Australia, are significant but it is not possible to extrapolate from them and and estimate any potential changes to historical results. "We are selecting a further set of assays from the 2013 drilling program where values of between 1.0 & 2.0 g/t have been returned, and we will carry out screen fire assays on those," said executive chairman Mick Billing in a statement. The companyh said following receipt of the final fire assay results from the 2013 drilling program, 55 samples with fire assays results greater than 2.0g/t were selected for follow up screen fire assay. "When gold mineralisation includes substantial coarse gold, there can be instances of upgraded values on re-assaying using the considerably more exhaustive screen fire assay process," Billing said. Of the selection, 18 samples were either downgraded or returned the same value, with the remaining 37 samples returning improved gold values. A review of historical assays from drilling programs in the early 1990's showed that of approximately 3,500 assays of intersections with gold values greater than 0.5 g/t, only 156 were subject to screen fire assays. Information in respect of any upgrade from original fire assays is not available. Story provided by
