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. Of the selection, 18 samples were either downgraded or returned the same value, with the remaining 37 samples returning improved gold values.\n \nA 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.\n \nCommenting, Mr Mick Billing, Executive Chairman of Thor Mining, said: \"these new results may be significant however is not possible to extrapolate from these, and estimate any potential changes to historical results.
