Woodie,
Back in September 2016 just before GRB did the Capital Raise and issued new shares at 2.5¢ you had a look at the Share Registry (presumably) and reported there were 450 people (entities) that held more than 100,000 GRB shares each.
If you have access to a more recent snapshot of the Registry, do you know how many people (entities) individually hold 1,000,000 or more shares?
Thanks, Dan
