Ok I stand corrected, so let me restate that the upside down Elephant's body is below 1700 meters.
Thanks Hoov, What would we do without you?
Probably stumbling in the dark and cursing every minute. That is why we need this forum.

As for doubling our resource? It is wild speculation but I did not go into this stock because of known info but mostly based on what I speculate is it's future potential.

Double the distance doubles the resource. Simple rule of thumb.

However I qualify that to a 50% increase above the top's because due to the smaller drills working top side they will increase the top resource by in-filling and perhaps extend that resource's external dimensions. The top will be higher than that 11 million tons
I like simple or rough calculations because they skip over complicated and unresolved issues.
Many thanks to all, Ed.
