From the recent report of the European Union (https://ec.europa.eu/enterprise/policies/raw-materials/files/docs/crm-report-on-critical-raw-materials_en.pdf).
Antimony is ranked as number 3 of the most critical resources for the EU, its economic importance is greater than the one of Niobium and the supply risk too. With about 23k t Sb Global Minerals is owner of one of the larger ressources out there (number 5 or 6 world wide) and could be the only producer within the EU in a short time.
To cut a long story short: Silver is very nice but Antimony is even nicer. Germany so far guaranteed loans for Tungsten an Niobium projects outside the EU. I shouldn't wonder if it would possible to receive such a guarantee for ramping up the first and only Antimony mine within the EU.
