Bronze Sculpture Repair

Terrible accident involving a Sergio Bustamante bronze sculpture of a rhinocerous with four eyes riding a bicycle. It fell to the floor and broke off of it's base. Contacted the Bustamante home gallery and never could get a response.

Any suggestions, ideas, recommendations on getting this repaired? We love it and miss having it out and around.
