Hello Frank
There is no simple answer to that question Frank as the economics of pipe potential differ radically with tonnage, grade, proximity to power, labor, water, transportation, etc, etc.
However, you can do similar searches on various kimberlite economic factors which might help you arrive at an informed perspective.
One in particular I did over the past few days produced some interesting Quebec & other kimberlite age dating information raising interesting questions about the degree of erosion over the last 400 to 1,000 million years.
As I alluded to on another thread, in this regard, I believe one play in particular offers some intriguing geological, economic and investment fundamentals which we should be able to discuss in a week or two.
In advance of that however, do some DD on the issues I raised and read Kaiser's Sept bulletin for some technical perspective along with one of Fagan's recent bulletins. There are others, but I can't be too specific right now for previously outlined reasons.
Regards
