Ann: Goulamina on Schedule Post Discussions with Mali Government, page-702

I'm not sure if DSO is feasible at current prices.
From the table below we might get $290/t interpolating to 1.6%
I presume this is a FOB cost, our trucking & port costs are $100/t from the DFS (excludes shipping)

That leaves $190/t for mining, crushing to 6mm, royalty etc etc
Simon's first estimate at production cost was US$50 lower than the DFS cost so $262/t (C1 DFS $312/t)
Then a month later (Dec'22) said US$260-300 FOB Abidjan
Then at the AGM said "will come out with a better price estimate than the conservative 300-350/t"

So no matter which figure you use, there is going to be very little profit if any at current prices.
So IMO DSO is mostly a non issue - don't tell the Mali Govt that though.
Of course we do want to test & commission the logistics.
