A 39.1 g complete and fully crusted stone found in Morocco in 2007.

Fine to medium-grained (<1.2 mm) unbrecciated, cumulate-textured stone. Composed essentially of enstatite with interstitial Si-bearing kamacite; sulfides (troilite, daubreelite, brezinaite, oldhamite, alabandite, niningerite, caswellsilverite), graphite, plagioclase, a silica phase, and schöllhornite, a weathering product of caswellsilverite. Weathering grade is low.
