pyrrhotite (pĭr`ətīt) or magnetic pyrites, bronze-yellow to bronze-red mineral, a sulfide of iron sometimes containing nickel. It tarnishes easily and is somewhat magnetic. It crystallizes in the hexagonal system, but appears usually in massive form, and occurs chiefly in basic igneous rocks. In some areas, e.g., at Sudbury, Ont., Canada, it is associated with pentlandite, an important ore of nickel. It is found also in the United States, Europe, and South America. pyrrhotiteIron sulfide mineral in which the ratio of iron to sulfur atoms is somewhat variable but is always slightly less than 1. It commonly is found in association with other sulfides. The variety troilite, with a composition near that of iron sulfide (FeS), is an important constituent of some meteorites. |

The KWG-Spider intersection inferred distal style VMS mineralization, the anomaly located 1200 meters to the NW on the new Freewest option property was interpreted as being proximal style mineralization, where higher copper values would be expected, however only pyrite and minor pyrrhotite was intersected in this hole, containing no significant copper or zinc values.
