"presume all profits would go towards paying the funding down - this would be proportionate to the relevant % stakes each group has in the JV."

Which is what I assumed too, but it brings me back to the question what are the exact terms of the JV or exactly how much funding has to be paid down first

Be nice if the JV partner made an offer for GBGs stake in the mine as even if they didn't take it the market would then have an idea of the value here, right now it's being priced as a shell with 2.5c cash backing
