  In this work we study a mirror model with inverse seesaw neutrino masses in
which symmetry breaking scales are fixed from bounds in the neutrino sector.
The Higgs sector of the model has two doublets and neutral singlets. The mirror
model can be tested at the LHC energies in several aspects. Two very
distinctive signatures of the mirror model are a new neutral gauge boson
$Z^{\prime}$, with a high invisible branching ratio, and a heavy Majorana
neutrino production through the decay $Z^{\prime} \rightarrow N +\bar \nu$.
This result is compared with heavy Majorana production through heavy pair
production and the consequent same-sign dilepton production. The other
important consequence of the mirror model is the prediction of the Higgs mass.
A particular solution leads to a Higgs in the same region as in the standard
model. There is, however, another natural solution where the Higgs mass is
above 400 GeV.
