Hi Benton, Just catching up on last night and today's postings. Read all your posts as very enlightening but have a question concerning this post. You say, "they cannot just start punching holes through the chrome to see what is there", but of course they have punched through the chrome layers in order to know the thicknesses of the chrome beds. Once through could they or would it not be wise to do some down hole EM's to see if there is anything beneath these chrome layers. I think I read that the VTEM's do not penetrate this chrome mineral very well. Just a question and thanks to anyone including Benton for an answer. GLTA the deputy
