Premier League new boys Birmingham are expected to finalise the season-long signing of Hart following the end of England's European Under-21 Championship campaign.
Eastlands boss Mark Hughes is willing to loan Hart out next season to allow the 22-year-old to gain further experience at first-team level.
Hart started last term as the club's first-choice stopper, but he was dropped to the bench following the January arrival of Shay Given from Newcastle.
He now appears to be on his way to St Andrew's and Gold expressed his eagerness to conclude a loan deal for the former Shrewsbury Town youngster.
"It will be a disappointment if we do not tie up a deal quickly," said Gold in the News of the World.
Hart is currently with the Under-21 squad in Sweden and admits he must be playing regularly next season if he is to break into the senior squad for the 2010 World Cup finals.
"The coach has said you need to be playing," said Hart. "That is what you want to be doing anyway, regardless of whether it gets you in the England side."
