RE:RE:US Roadshow Starts on MondayI was referring to a Preliminary continously updating in house estimate that is usually maintained on which infill drilling can proceed or for example, a large bulk sample designed.
More or less low level Inferred.
The Krieging model is fairly adaptable to such progressive estimates.
A large stratified bulk sample would add substantively to sampling density towards Measured or Indicated categories .
Of course, it's not unusual to begin mining in the absence of a formal MRE, if external financing is not required, as would be the case for toll milling...
