A study on the possibility of mirror baryons in the new mirror model as a dark matter candidate has been performed. It can be shown that mirror baryons can be a dark matter candidate assuming at this time baryon-anti baryon pairs almost vanished through annihilation process leaving only mirror baryon due to baryon-anti baryon asymmetry which then become dark matter candidate in this model. Annihilation process occurred through mirror photon. The upper limit of the mirror photon mass is estimated around 11,5 GeV and the upper limit of the freeze-out temperature is estimated around 170 MeV
