I agree that it looks very much like Josephine's Crown (not mohawkite). Josephine's Crown is not strongly magnetic (perhaps a bit of weak magnetism in areas, but generally not). Contains chalcopyrite and pyrite (which give off the sulfurous smell when grinding). Also can contain minor traces of gold, silver and platinum. There is a similar-looking material from the same area of SW Oregon that is marketed under the name "pulsite" (after the mine owner). Pulsite is similar, but has smaller grains of metal oxides, and less quartz. Desirable stuff and a good find. Your cabs look great, too. Thank you very much R2D - that's very helpful information. I was basing the "magnetic" thing on the link that Daniel posted in that other thread - the study states "strongly magnetic" as a characteristic of Josephinite.
