Can mold survive on copper?
To;dr - Yes, and probably.

Copper has been used for a couple thousand years now for piping and as a part of brass for plumbing fittings and handrails. It is naturally anti-fungal and anti-bacterial. You don't need antibiotics or cleaners on real brass handrails.

The Romans used it for plumbing and although they really didn't know anything about bacteria it kept them healthier. (Unfortunately, they also used lead which is poisonous and may have contributed to insanity in their upper clas population.)

Copper is also used in asphalt shingles and as a paint additive, as an inexpensive anti-fungal and anti-mold agent to prevent moss, mold, and mildew growth.
