@Bazsa they aren't just kicking rocks and staring at old shafts (lol)
BMV have no benefit in delaying their reconnaissance and proving this old, functioning mine.
Things that have changed since gold was last plucked from Gubong:
Technology has improved;
Price of gold is multiples of where it was.
We have a friendly jurisdiction, no royalties, low tax rate.
We have brought onboard BMV, with two heavy hitters from the industry who's specialty is re-opening old mines.
SAU knows its strengths, as well as its weaknesses. We picked up these permits for bugger all, and know that we don't have the smarts to pull the gold out of the ground. So what have we done? Brought in the experts, to find it for us, whilst paying for the privilege.
