Query: NRQCD results on the MILC extra coarse ensemble   We present preliminary results using NRQCD to describe heavy quarks on the
MILC 2+1 flavour dynamical extra coarse ensemble. We calculate the spectra of
low lying states in bottomonium to complement earlier results on the finer MILC
ensembles. We then exploit the coarseness of the lattices to calculate charm
propagators using NRQCD. These are used to examine the charmonium spectrum and
to calclate the mass of the $B_c$ using NRQCD. Finally we look breifly at the
$B_d$ and $B_s$ systems using the imporoved staggered formalism to describe the
light valence quarks.
