You should have no problem recovering gold using strong base anion resin. The only strong "chelator" in most gold baths is cyanide, unless you are using a sulfite system, or you have a acid gold chloride strike. The gold is in the form of a gold cyanide complex which exchanges quite nicely. And free cyanide comes out on the SBA resin as well.
