Ann: Onshore Indonesian Oil Operations Update - December 2019, page-9

You are on the same track as me mate, sort of.
However going by memory it's not 50/50 with the Indonesian tax bizzo, close to it though. Think closer to 45/55 (BAS gets somewhere around 55%). Don't quote me on that, it was someone ago Tino explained it, and don't have it in front of me.
I had done a quick calculation myself, though it means jack s***. I only came up with a figure out of my imagination for admin and fees... and had it somewhere between 250 to 290 thousand net profit for month.... don't have the time to look and figure the historical figures though.
Anyway, this still remains in the bottom drawer for me, at least till new aquisition....or something else out of left field. And still happy with my punt.
Above, is all my opinion only.
Cheers,
Mick
