  Here, we report a systematic study on the Hall-effect of the semi-metallic
state of bulk MoTe$_2$, which was recently claimed to be a candidate for a
novel type of Weyl semi-metallic state. The temperature ($T$) dependence of the
carrier densities and of their mobilities, as estimated from a numerical
analysis based on the isotropic two-carrier model, indicates that its
exceedingly large and non-saturating magnetoresistance may be attributed to a
near perfect compensation between the densities of electrons and holes at low
temperatures. A sudden increase in hole density, with a concomitant rapid
increase in the electron mobility below $T \sim 40$ K, leads to comparable
densities of electrons and holes at low temperatures suggesting a possible
electronic phase-transition around this temperature.
