Sulphur is concentrated by thermochemical - it's dissolved in hot water, and when the water hits surface and cools, the sulphur condenses out. Not going to happen on a dwarf.

I suggested once that the surfaces of sulphur moons like
Io might be a good source of accessible
chalcophile minerals, which no class of asteroids is noticeably enriched with. But I could never quite get a
JTAS article out of it.
One problem with the suggestion is that sulphur moons, being of necessity in close orbits around large gas giants, are likely to have a severe radiation hazard from their plasma toruses.
