  8. Create triangulations from contour lines: 38:50 to 43:30

No single time accommodates all time zones; so the previous session was at 5 am and the upcoming session will be at 5 pm (Perth-time) to accommodate most users.

The next on-line GoToMeeting session:

Perth time (UTC+8): Tuesday 1 September @ 05:00 pm in Perth (UTC+8)

Duration: ~60 minutes

The following topics will be discussed:

  1. Create drill-holes and data composites: ~10 minutes

  2. ERF and HR calculations (detail and quick): ~10 minutes

  3. Open-pit reconciliation: ~15 minutes

  4. Answer any other questions: ~25 minutes

If you have specific questions that you would like me to cover, please mail them to or ask questions during the session.

Below is ERF-function output, but stope HR-values can also be estimated from many stope surfaces simultaneously.

Hope to meet you on the call, keep well.
