Hmmmm....
I can understand the 'secretiveness'. Remember the fiasco of El Tigre! There was a lot of hype, not by ARU, but on the boards and the SP went along for the ride. Sadly, when the results were disappointing the SP sagged considerably.
My feeling is that ARU management is trying to avoid a repeat.
Maybe someone can answer this: Do they have to report on every hole they drill or have analysed?
