Borici-Creutz formulation describes two chiral fermions(minimally doubled)
on a 4D lattice. But this formalism breaks hypercubic symmetry on the lattice
and requires counter terms. The Borici-Creutz fermion is not yet fully explored
in lattice simulations. In this talk, I will discuss a mixed action
lattice study of Borici-Creutz fermions on staggered sea. We first fix the
counter terms non-perturbatively, then we present the results for chiral
logarithm in pion mass, partial quenching, Delta_mix etc.
