The reason we find large concentrations of gold in many places is because goldrich rocks have been eroded by rivers, and the gold grains have been deposited by those rivers simply due to density contrast. That leads to a secondary 'placer' deposit of gold which is far more enriched than the rocks from which the gold originally came.
