Out of curiousity, is there a page about monsters targeting a knight because of the mineral they have picked up?

I found this quote in a situation room. It has a knight working at a computer with Hubert, the despiked jelly. In front of him is a wolver in the middle, with a huge red mineral deposit on the left and a huge green mineral deposit on the right.

"Certain types of monsters seem to be attracted to different combinations of minerals found down here in the Clockworks."

Is this true? If so, is there evidence to prove it? Hmmm....
