FOV 2.5 x 2.8 mm. Found August 1997 (Poudrette quarry, Mont Saint-Hilaire, La Vallée-du-Richelieu RCM, Montérégie, Québec, Canada). MOB coll. This specimen was identified at the Canadian Museum of Nature. It came from an igneous breccia and was associated with khomyakovite (http://www.mindat.org/photo-166793.html and http://www.mindat.org/photo-166788.html) and manganokhomyakovite (http://www.mindat.org/photo-279269.html) from which it is visually indistinguishable. (Most xls are zoned. This particular xl may or may not be predominantly ferrokentbrooksite but the analysis showed ferrokentbrooksite on this specimen and it appears to be the most common eudialyte group member in this find.) The dark prisms are probably an amphibole such as richterite. Mineral

Ferrokësterite, Arsenopyrite Locality: Cligga Mine, Cligga Head, Perranzabuloe, St Agnes District, Cornwall, England, UK Size: 2.8 cm x 2.4 cm x 1.3 cm Ferrokesterite is a rare copper sulfosalt, the iron analogue of kesterite. This old Cornwall mine is the Type Locality. A few ferrokesterite blebs with the dark blue-violet tarnish are noted on both sides of the slab of metallic, bladed arsenopyrite. Rare and excellent combination material from the Alan Barnes and Matioli Collections. Mineral

Ferronickelplatinum Locality: Urals Region, Russia Original description: Small (4 mm in diameter) nugget of the sample obtained as native platinum, but showed to contain essential Pt, Fe and Ni - thus revalidated to ferronickelplatinum. Specimen comes from a placer probably from nearby Nizhne Tagilsk, contains small chromite grains and awaits future microprobe analysis. Mineral

Ferronigerite-2N1S Locality: Stiepelmann Mine, Arandis, Swakopmund District, Erongo Region, Namibia (Locality at mindat.org) Size: 2.8 x 2.3 x 1.4 cm. A superb hexagonal crystal of the rare mineral Ferronigerite. This tabular crystal has a deep reddish-brown color and a superb luster. It is .9 cm face-to-face (not even corner to corner, which would be more), which is huge for Ferronigerite. And it is very nicely colored. A great example of the species. Ex. Charlie Key. Mineral

Ferronigerite-2N1S Locality: Stiepelmann Mine, Arandis, Swakopmund District, Erongo Region, Namibia (Locality at mindat.org) Size: 0.6 x 0.5 x 0.2 cm (largest). Five sharp, doubly-terminated hexagonal crystals of the rare mineral Ferronigerite-2N1S. These tabular crystals have a deep reddish-brown color and a superb luster. Great examples of the species from a recent find around 2004-2005. Ex. Charlie Key Collection. Mineral

Orange crystal of the mineral of the rhodonite group: ferrorhodonite (IMA 2016-016), from the type locality in Broken Hill (New South Wales, Australia) and only one of the two known localities worldwide in a marix of galena. Ferrorhodonite can be distinguished from rhodonite by its brownish pink color. Mineral
