 Luzonite mine and chemical compositions of sulfur arsenic copper but different crystal structure is different, both each other is dysmorphism mineral; Luzonite mine is generally block with purple brown, also known as the massive sulfide ore, but yield less than arsenic copper, gold in foreign mineral books listed as major Luzonite mine one of origin.
