  Mirror matter models have been suggested recently as an explanation of
neutrino puzzles and microlensing anomalies. We show that mirror supernovae can
be a copious source of energetic gamma rays if one assumes that the quantum
gravity scale is in the TeV range. We show that under certain assumptions
plausible in the mirror models, the gamma energies could be degraded to the 10
MeV range (and perhaps even further) so as to provide an explanation of
observed gamma ray bursts. This mechanism for the origin of the gamma ray
bursts has the advantage that it neatly avoids the ``baryon load problem''.
