  We present the first predictions for sub-threshold open charm and charmonium
production in nuclear collisions. The production mechanism is driven by
multi-step scatterings of nucleons and their resonance states, accumulating
sufficient energy for the production of $J/\Psi$, $\Lambda_c + \overline{D}$
and $D+\overline{D}$. Our results are of particular importance for the CBM
experiment at FAIR, as they indicate that already at the SIS100 accelerator one
can expect a significant number of charmed hadrons to be produced. This opens
new possibilities to explore charm dynamics and the formation of charmed
nuclei.
