. deposit, the precision of the gold analysis may be less than that predicted for the ideal type of deposit' as sumed here. The undesirable effeot of systematic trends in gold content can be reduced by a proper sampling plan, but such procedures are beyond the scope of this paper. Sampling plans are treated in detail by l(rum bein and Graybill (1965) and by Miesch (1967b). It can be shown ...

freemilling and gold can be recovered by gravity and/or direct cyanide leaching. Some epithermal deposits may be freemilling (such as the oxidized portion) but more commonly contain significant amounts of sulfides in which gold occurs as micrometersized inclusions or as submicroscopic gold and are therefore refractory. When the silver grade in an ore is high (>10 g/t) and/or the gold is ...

Free gold in quartz veins comes in all sizes, with a full range of gold particles from obvious stuff easily visible to the eye down to gold that can barely be seen with a magnifying glass. The coarser stuff can be found with a metal detector, while the smaller sized gold requires that the rock be crushed and the resulting powder panned. The coarse and easily visible gold in quartz may be ...
