Nodules of pyrite; FeS2, or chalcopyrite, CuFeS2. I tend towards the former due to the morphology and color, but I ain't a geologist and just collect the crap for fun, so i am not certain. It is almost definitely a metallic sulfide though. I would be really happy with those finds, honestly. Nice job!
