Mandarin stump transplant survival?

Hi,
Last winter a 30 year old Mandarin tree stump, freshly cut to 750mm above ground was transplanted (as a last minute repreive)
The tree was a good fruiter... but building developments took precedence.
Roots were heavily trimmed but some fine roots remained,
In early summer many green shoots grew to about 75mm.
Now, well past mid summer and heading into autumn, these shoots have died back.
What are the chances of survival and re-growth?
