Lucky man to get it strait from the source. Unfortunately I cant see much detail as the pictures are not real well focused. It'd be a good idea to take them in natural light as well and maybe a bit closer. I'd say your husband could probably make a better ID of them with just a chat with fellow workers at the mine.
