Dwarves still in the Ered Mithrin?

[goldfinger]

I have found two things that are rather interesting about the Ered Mithrin. In Appendix A I found that in the chapter about Durin's folk, it states that Most, not all of Durin's folk left the Ered Mithrin. And I also found that in the Hobbit Thorin sent messengers to the Ered Luin "the mountains in the North". So I'm lead to believe as a Dwarf scholar that their were still at least one or two small colonies of Dwarves living in the Ered Mithrin. So what do my fellow scholars think?
