@Merovius Not uncommon on Wikipedia, where various editors add facts over time, sometimes without reading the existing page too closely.
I found this EU page https://rmis.jrc.ec.europa.eu/rmp/Dysprosium which gives a 2021 figure of 3126 tons produced, 40% of which was from China, 31% from Myanmar, and 20% from Australia.
Do I have to look at & update all of the rare-earth pages now? Maybe tomorrow!
