A subsidiary of Soul City records. As its name suggests, Deep Soul was dedicated to reissuing soul records of particular intensity.  It operated from 1968-70, and released a mere half-dozen singles, all of which were licensed from American sources.   The singles, which appeared in a DS-9000 numerical series, command respectable prices nowadays. Thanks to Robert Lyons for the info.
