Limonite after pyrite occurs as films on some fractures and as seams and blebs associated with quartz-calcite veins, and opaline silica veins.

Mineralization is comprised largely of pyrrhotite, chalcopyrite, pyrite with lesser amount of sphalerite and rarely galena.

Mineralization is present in quartz veins and stockwork or breccia with disseminated pyrite.

No fresh pyrite was visible in the core however, except occasionally below the FW vein in the underlying Proterozoic granite.

The mineralization at Mouta is characterized by the presence of massive black chalcedonic quartz veining with chalcopyrite and disseminated pyrite on fresh surfaces and with copper oxide minerals on weathered sections.

The mineralization consists principally of chalcopyrite with minor amounts of pyrite, bornite, malachite and erythrite, and occurs within the veins in association with quartz, carbonate (ankerite?), and sedimentary rock inclusions.

This association of disseminated pyrite and fuchsite (a green mica containing elevated chromium) in ultramafic rocks with nearby gold is noted at a number of other gold occurrences in Lapland, as well as other greenstone belts around the world.
