  Directional detection is a promising direct Dark Matter (DM) search strategy.
The angular distribution of the nuclear recoil tracks from WIMP events should
present an anisotropy in galactic coordinates. This strategy requires both a
measurement of the recoil energy with a threshold of about 5 keV and 3D recoil
tracks down to few millimeters.
  The MIMAC project, based on a \textmu-TPC matrix, with $CF_4$ and $CHF_3$, is
being developed. In June 2012, a bi-chamber prototype was installed at the LSM
(Laboratoire Souterrain de Modane). A preliminary analysis of the first four
months data taking allowed, for the first time, the observation of recoils from
the $\mathrm{^{222}Rn}$ progeny.
