Hmm,
I think the difference is that they have already found traces of Gold on their land.
Generally most exploration companies are at stage 1, go out and find something.
I think here, they are at stage 2, they have found something, and need funds to further detail exactly how much has is actually there.
So regardless, as long as the traces are correct, the promise of Gold is 100%. It is more of a question of exactly "how much".

They are literally betting the farm on it so they must be very confident of a positive outcome.
The backstory of the company begins at the turn of the century. In 2000, the Prendergast family bought a 96,000-acre farm in New South Wales, Australia, and in 2001 prospectors found a number of unexplored mineral deposits in the area.
