David, If you want clarification of any of these points please do not hesiate to contact me. This is the method employed at all mines where stope design is carried out from a block model. Stope design against a block model is done for most mines during the feasibility stage where cashflow figures must be reported, then during production at smaller mines stope design is normally just done against geological interpretation with evaluation against a block model once a year to produce the grade tonnage reports, while at larger mines where mine planning is ongoing stoping is continuously being designed against the block model.
