RE:RE:TV Provides Update on Search and Dewatering Efforts at PerkoSo, I'm absolutely not an expert on this topic, but it appears that Trevali owns the mine, however, as per the Perkoa NI43-101 document,
"Roscoe Postle Associates Inc. (RPA) was retained by Trevali Mining Corporation (Trevali) to prepare an independent Technical Report on the Perkoa underground zinc mine (Perkoa), located in Burkina Faso, which is operated by Nantou Mining Burkina Faso S.A. (Nantou Mining). Trevali holds a 90% interest in Nantou Mining while the Burkina Faso State holds a 10% interest, in accordance with the Mining Code."
I can't find any information whatsoever on Nantou Mining, nor am I at all versed in ownership structure, but is there a possibility that the fallout from this will land on Nantou Mining instead of Trevali? Perhaps there's some clause that will allow them to simply abandon the project completely, and write it off, instead of being stuck paying the bill for the next decade?
