ore deposit evaluation
notation 05 more like this
definition This the final phase of evaluation. Knowledge of the deposit must be as precise as possible, hence systematic core drilling and eventually reconnaissance mining workings. This phase should lead on to a Go/No Go decision (possibly revisable, depending on e.g. prevailing economical conditions) based on a feasibility study report. more like this
