No. There are no semi-empirical parameters for Cu implemented in
Amber9 or even in Amber10. If you can find a DFTB parameter set for
Cu, then Amber 10 can use it (assuming it is compatible with the other
parameters available).

Other options would be to:
1. Use the Amber / PUPIL / Gaussian interface to use a more general
quantum method from gaussian. This interface is available in Amber10.
2. Use Gaussian itself (either with ONIOM or full quantum).
