Hi Reiner, looking at Tritons Ancuabe project, which is in the expandable graphite space you may need to update your spreadsheet to current stage being "early works well advanced" . With Triton being the next likely producer in the expandable graphite space it would seem a glaring error in your comparison info.
Anyway, this from their website on their status as Board approved and early works commenced
"The Board approved development of our flagship Upulo (Ancuabe) Graphite Project and early works activities are well underway with mining and processing scheduled commence in the first half of 2020. Ancuabe’s large flake and high purity graphite is a key differentiator and is well positioned to be a market leader in the expandable graphite market."
