I did a tile change! 
BoP was working a plains hill mine. I put it on grassland village located NW of Cannae instead. Cannae started working the new grassland riverside cottage. This means: -4 gold, +2 beakers, +2 food in BoP. I think this is a clear improvement. Of course this means that reaching Calendar EOT98 would be harder, but you said that our jungle chops were also timed so that our workers start improving resources anyways on T100, right?
(If you prefer the mine and want those 4 gold, let BoP still work the village and work plains hill mine instead of the cottage S-S of BoP. That simply wins by 1 beaker.)
