Goldlake knows what its doing. But they also know investigating remote areas away from the known gold vein are a win win. If they find gold, its a huge win for them without having to do much.
If they don't find anything, the inherited investors of SLTA panic and their people can quietly, silently accumulate while they appear to lose interest in a project that they deep down, know contains billions of dollars of gold.
I could be wrong, but seen it before.
