Unless you are trying to mislead us then these two comments indicate that more drilling is required, and this would be on BHP land, for which they need an agreement.

"UMC have not completed drilling Railway and I would not expect to see the finalisation of hydrogeological studies until such time as they have a complete 3D image of Railway."

"UMC will not be able to complete hydrogeological studies until they come to some arrangement/ agreement with BHP."

Yes, missed the point, confused by the spelling of "flower" (SIC).

Railway Project - oh the irony - ha - irony even has iron in it!
