Caeté has been running fairly stable during a quite a long time, with minor upps and downs in production, I think it's ok.
Regarding Turmalina, I believe Fred Herman addressed this in the Q3 CC. They're changing the ground support so it's more reliable, but it's taking time to implement. It should pay off in the long term.
With that being said, it would be nice to see rising production from Turmalina in Q1 (or Q2) this year. They probably need to produce north of 25k to be cash flow positive. If/when that happens, it should be reflected in the share price.
