Detection of Advanced Fusion in Distant Planet Atmospheres

Consider the possibility that a sentient species on a planet in another star system acquires advanced fusion technology. That is, they can not only fuse hydrogen atoms together to make helium and useable energy, but also gold for self-enrichment or rare and heavy metals for machines like cars, planes, and space ships. After some period of time, their fusion industries might overweight their atmosphere in these heavier metals relative to pre-industrial background levels. If we construct sensors that can measure elements in distant planetary atmospheres, then would this be a way to detect advanced alien civilizations?
