lets assume they don't get 90%+, page-2

Marketscan, give it a rest. If you want to take up the offer at 5.5c (which I'm sure you already have) then good luck to you.
If they don't get 90% as you suggest why is there need to be so anxious. A better offer will come to those who still hold shares (doubt you will be one of these) if the company still wants 90%.
If a better off doesn't come BCP will be the majority holder and unlikely to sell below their buy in price of 5.5c. The remaining holders see the company as having more value than this price which would signify 5.5c as a likely future floor price. Drilling and especially further production will still occur as BCP are buying in to make money not lose it and the SP will continue to respond accordingly.
The company has about 2 billion shares on offer. If BCP own say 70% of these that still leaves about 600,000,000 in play which is still a huge amount enabling liquidity or SP movement...
