A computer program, GOLDSIM, is offered that determines the sampling distributions of samples taken from gold-bearing lots. The lot is split into size fractions that are weighed and assayed. It is then modelled in terms of the equivalent gold grains in the size fractions and these data are fed into GOLDSIM. Numerical examples and a listing of GOLDSIM are presented.
