In the presentation, he was refering to DE1 plunging to the south at an angle of 60 degrees. He then said IF the down dip extension were to total 300 meters, they would have over 700 million tonees of ore.

This was not meant as a pump, just reclarifying content from the presentation.

I do wonder though, are they or have they discovered a 300 meter down dip extension? :-)
