Case history – Ore contact mapping
The cross-section to the left shows the down-dip extension of a massive sulphide orebody inferred from three 60m spaced surface drillholes. Many questions still had to be answered in order to optimise the mine plan. For example:
Where exactly did the ore pinch out? Was the ore continuous?
How much did the ore
thickness vary?
Was there more ore down dip?
