These new Platinum CRM’s are all made from material supplied by Anglo Platinum.  Two of the new PGM reference materials are replacements and two are to fill in some grade gaps. AMIS0127 Platreef replaces the depleted AMIS0015.  AMIS0074 UG2 replaces the depleted AMIS0006. The low grade AMIS0099 and AMIS0107 were specifically made to check mine residue (tailings, slimes) analyses.
