  In this paper, we formulate the Mimetic theory of gravity in first-order
formalism for differential forms, i.e., the mimetic version of
Einstein-Cartan-Kibble-Sciama (ECKS) gravity. We consider different
possibilities on how torsion is affected by conformal transformations and
discuss how this translates into the interpolation between two different
conformal transformations of the spin connection, parameterized with a
zero-form parameter $\lambda$. We prove that regardless of the type of
transformation one chooses, in this setting torsion remains as a
non-propagating field. We also discuss the conservation of the mimetic
stress-energy tensor and show that the trace of the total stress-energy tensor
is not null but depends on both, the value of $\lambda$ and spacetime torsion.
