Niobium is a TCE20 Apr 2021 09:45
Taken from Wikipedia:
A technology-critical element (TCE) is a chemical element that is critical to emerging technologies.[1]
Technology-critical elements are elements for which a striking acceleration in usage has emerged, relative to past consumption. [2][3][4][1]
Many advanced engineering applications, like clean-energy production, communications or computing, use emergent technologies that utilize numerous chemical elements. [2]
I think we can say this is big news for POLY.
