Product description:AbstractDiamond Drill Hole MD12 was partially funded by a Rediscover Victoria Drilling Initiative grant and was drilled during February and March 2010. Its main purpose was to test for further evidence of an intrusive related gold system (IGRS) driven by a previously undiscovered intrusive body beneath the Drummond North Goldfield. No igneous rocks were encountered despite the hole reaching a depth of 1 km. Sub-economic mineralisation of three styles was intersected. The first is characterised by relatively flat-lying auriferous quartz veins containing abundant arsenopyrite. The second is represented by narrow, steeply-dipping quartz veins and wider disseminated zones (concentrated in grits?) containing gold, pyrite, chalcopyrite, arsenopyrite, scheelite, bismuthinite, tetrahedrite and sphalerite. In addition, narrow chlorite-calcite-pyrrhotite (propylitic) alteration zones accompanied by gold, chalcopyrite and scheelite occur sporadically down the hole. The last two styles of mineralisation are clearly granite related, perhaps to different intrusions. The best gold intersections were 3.8 m @ 1.65 g/t Au, 0.62 percent Cu and 9.4 g/t Ag and 2.9 m @1.51 g/t Au.
