Sorta buried in there, but they do note that this is not the first time the transmutation of lead to gold has been accomplished, just the first time it’s been accomplished as near misses in a particle accelerator.
Well technically, the starting points were always other elements like bismuth, and not lead. I believe the authors checked, and noted that in the paper: https://journals.aps.org/prc/abstract/10.1103/PhysRevC.111.0... )
Spallation on a lead target will produce a wide range of elements, including gold.
