Hi Hotrods
The historically known correlations (drilling to mining to plant recovery) at MStar show (see my post under the Finding a gold mine thread) that typically a fracture in a bulge that is heavily mineralised will have a single bonanza hotspot surrounded by a declining high grade zone.
Experience yields the right drilling pattern. Generally a mineralised area will be minable by 3 sets of 2 hand held miners each producing 10,000t of high grade quartz gold ore per year (30,000t/yr = almost half the plant nameplate capacity.
A historically typical vein will be circa 100,000 tonnes or more as based on average extension of half way across the dyke bulge. That’s 1year mining per high grade vein.
Typically if a hot spot is found then about 30 short holes are needed to fully drill the zone and the average grade of all those holes is 10g/t but the average grade with the 2.5 multiplier is 25g/t but with development and mining dilution the head grade might be 15.
As I have said before, Matt Gill and Tom deVries know all this. They have lived and breathed this stuff in VIC for 40 years.
TdV will continue to be correctly conservative in ASX releases by carefully building the story.
He did not say Bonanza grades but Boz chose to start a thread sayin that.Personally I would let TDV run the optics to slowly and carefully win over the jaded Collins st investment community.
