RE: Kimberlite pipes.Substantial? Maybe, perhaps and could be. Just because there is kimberlite, it does NOT mean it is diamondferous!
Big Difference. A BHP team years ago discovered one of the largest kimberlite pipes in the world, but it contained no significant amount of diamonds.
Note that I am holding MTX shares as a long term investment/speculation. With the latest property diversification into Morocco and Mali and with Peter G. at the helm, I am resting easy. What will the future hold? It will be all upside for me I believe.
