BHI did the gravity and geology? If so, then MBMI is the one that took BHI's gravity map and applied that ridiculous label "red=barite and green=limestone" on it.
I am sure that a company with the stature and sophistication of BHI must be a bit disgusted with that, and not very pleased with the obvious misuse of the data (even though it was limited to a map, with no supporting explanation or data).
Also, you make a leap of faith to say that "They [BHI] felt LARGE scale mining was appropriate." Did BHI issue any kind of statement saying that? It takes little effort for a company like BHI to issue a MSA for buying barite. No risk to them, but MBMI has sure made good use of the MSA in an attempt to establish credibility based on the BHI name.
