UM-2 and UM-4 are discontinued and no longer available for purchase.
Certified Reference Material: Sulphide-Bearing Ultramafic Rocks
Printable version of the certificate (PDF, 22.18 kb)
UM-2 and UM-4 are from the Werner Lake - Gordon Lake district of northwestern Ontario. These rock samples are intended as reference materials for the determination of ascorbic acid/hydrogen peroxide-soluble copper, nickel, and cobalt in ultramafic rocks to evaluate their ore potential.
