Narrative:
On prado departure procedure was climbing ATC called traffic at 10 O'clock position; called in sight. They called air carrier Y traffic at 2 O'clock position; he responded in sight. On TCAS observed traffic conflict RA to level. Once clear traffic air carrier Y asked ATC what was that about? She responded you both had visual separation. We were not told to maintain visual separation. We were on departure procedure. Poor judgment on ATC; failed to maintain separation.
