Pyrrhotite Fe1-xS (x = 0 to 0.2) - 02.CC.10 (Strunz)(from Abandoned Mines in Palquico, Chile) I obtained these igneous rocks in the second expedition to Palquico, in a small and abandoned mine on top of the hill . It shone in the mine and when I hit it with the hammer throw sparks. Is found with pentlandite little brown crystals (in the first picture is easier to see them). It has low magnetic powers,so Magnetism increases with decreasing iron content. -- source link
