Bon Accord 282 JU farm.
A small (6 x 3 x 0.3 m) deposit of nickel minerals. Two mineralogically seperate deposits - one consisting of sulfides, the other oxidized.

Also a number of minerals in the system Ni-Sb-As were found, but were too small to characterize. Various PGM minerals : stibiopalladinite
(Pd5Sb2), naldrettite (Pd2Sb), ungavaite (Pd4Sb3), and sudburyite
(Pd,Sb). The Pt bearing PGM probably corresponds to genkinite
[(Pt,Pd)4Sb3] or platarsite (PtAsS). The grains containing Ru and
S very likely are laurite (RuS2) and ruarsite (RuAsS), but are too small to characterize. see Zaccarini et al (2014).
