  Several independent observations of the galactic core suggest hitherto
unexplained sources of energy. The most well known case is the 511 keV line
which has proven very difficult to explain with conventional astrophysical
positron sources. A similar, but less well known mystery is the excess of
gamma-ray photons detected by COMPTEL across a broad energy range 1-20 MeV.
Such photons are found to be very difficult to produce via known astrophysical
sources. We show in this work that dark matter in the form of dense antimatter
droplets provides a natural explanations for the observed flux of gamma-rays in
the 1-20 MeV range. We argue thatsuch photons must always accompany the 511 keV
line as they produced by the same mechanism within our framework. We calculate
the spectrum and intensity of the 1-20 MeV gamma-rays, and find it to be
consistent with the COMPTEL data.
