Automated Mining Units can convert to a different resource type — at least one of my uranium deposits started producing silver recurringly. Re-creating the the Automated Mining Units restored it back to uranium.
These things are super unreliable. A lot of the time I fueled them up, only for me to return and find that the fuel was all gone without mining anything.
Same for atmosphere harvesters.
From others on the internet, it sounds like:
1) This is a common bug.
2) The game designers would probably rather have use mineral/gas extractors as a better-supported mechanic. (These have been reliable for me.)
