Attached is a better scan as it ran overnight. I do believe Zn peak is starting to show. Nothing like real XRF tho in this case.
Also a pic of the box it came in, I bough it long ago because it was radioactive and looked unusual. Didn't know about the Zn until later.
?PS for the Amptek peak search to work, it seems to need 100 counts in the relevant peaks. This would be difficult to get with this lightly radioactive sample, but by eye you can pick out a bunch of good peaks.
