4 part video series on Renergen, page-31

That's exactly the motivation/inspiration if need/name one (for holding 10 years and beyond) --- "Renergen could be the OPEC of global helium"! If they can later further prove Sandstone reservoir! Renergen will be a very good candidate for this kind of long hold imho (during which there might be/will be volatile market if world economy in recession in early stage but as long as world still in shortage of helium its SP will eventually spike at some stage and then become stable once dividend starts flowing in continuously/reliably, guess that's the purpose of longterm hold..). Unlike some good ASX mineral/metal startups, had a fantastic run first after initial discovery then further proved up reserves/resources and later on either takenover by some larger player or if become a miner it has to keep growing (its reserves) through M&A activities or keep drilling to maintain revenues and LOM etc. (harder job i reckon), while Renergen's helium is totally different story here as it is constantly generated by the (the work of) bacteria deep under the earth so virtually endless once found...
(a bit wild musing here but could be true ..)
