Block 2 is in shallower water depths (which years ago was critical) due to past technological limitations ....Block 2 is also much closer to AKPO, and is nearly identical in depth, geology and structure.
The prospects Principle/Tome are huge, the largest in the JDZ, by far...these could well be Monster Elephants
Block 2 will be an easier drill, and development, imo...downside is that it could be boom or bust, because besides Principle/Tome, there isn't much there.
,....SEO put his chips on Block 2, and he hasn't been wrong about much so far.
