It is a good rule of thumb that investors tend to profit from the discovery/exploration stage and the period following production given all going well. Now all conditions as discussed above are matched, the only thing for so4 and kll is to go into normal production and then go into overdrive before the others like Apc and amn go online two years later. But I would avoid those in their development stage that need to raise money from time to time.

This is my opinion only and please do your own research before action. GL.
