He was referring to the other resident curmudgeon on the Geology forum here- JimBob is just a big softie. It's always hard to tell minerals from photos alone.Photo 1: Can you scratch this mineral with a knife? It looks somewhat fibrous- and may be amphibole (which covers a range of minerals). Is cleavage better developed in one direction, or is it more equal in 2 directions? It's not sphalerite.Photo 2: How soft is the gray mineral? Galena is fairly soft. Galena sometimes can be massive (too fine to see individual crystals). Can you see any crystals if you use a hand lens or microscope? Another possibility is chalcocite or digenite if you found it in an area with azurite. Can you describe the place you collected the mineral? an old mine? How much azurite was present? Malachite (green copper mineral)? Turquoise? Quartz?
