Ann: Block 9 Alameda 3 Appraisal Update (Alameda reservoir), page-722

Sonangol owe MAY nothing. People can't read quarterly reports properly and I'm shocked the amount of cash punters are splashing on a stock to financial reports they don't understand.

I'll reiterate again for everyone Sonangol provids MAY a 30 million dollar facility to draw cash from to use for Sonangol's share of the drill as each quarter is of drilling is costing around 17 million a quarter and MAY doesn't have the funds to cover all of this being the operator, so Sonangol has just provided them a call account they can draw funds from which evens out in the quarterly and you can see this as "Other (Contributions from JV Partner) ".

The sneaky thing MAY actually has done is used this Sonangol provided facility number as total available funding so they didn't have to answer the ASX question of whether they have funding for the next 2 quarters

Cash and cash equivalents at quarter end (item 4.6) 16,388
Unused finance facilities available at quarter end (item 7.5) 31,044
Total available funding (item 8.4 + item 8.5) 47,432

But who knows in the future maybe Sonangol has provided MAY with such a facility (secured by block 9) that they could use to draw further funds from for the project but it was never announced (again scant MAY information)
