  A wide range of dark matter candidates have been proposed and are actively
being searched for in a large number of experiments, both at high (TeV) and low
(sub meV) energies. One dark matter candidate, a deeply bound $uuddss$
sexaquark, $S$, with mass $\sim 2$ GeV (having the same quark content as the
hypothesized H-dibaryon, but long lived) is particularly difficult to explore
experimentally. In this paper, we propose a scheme in which such a state could
be produced at rest through the formation of $\bar{p}-^3$He antiprotonic atoms
and their annihilation into $S$ + $K^+K^+\pi^-$, identified both through the
unique tag of a S=+2, Q=+1 final state, as well as through full kinematic
reconstruction of the final state recoiling against it.
