I thought I would be clever by saying check out the PLAT index, but now note that Aquarius, Eastplats, Anooraq and Platmin are not on the Index, yet Wesizwe is...Doesn't make sense. But to answer your question AMS, IMP, LON, NHM, ARM, EPS, AQU, ARQ, PLN are all miners that produce the PGM basket(Pt, Pd, Rh, Ir, Ru) + Gold, Silver, Copper, & Nickel. Some operations also produce chrome from the UG2 economically, while others do not. This was mentioned by Barry in a previous post on the subject...yes...I'm a geologist!!
