1. Introduction. The Stillwater Complex, a late Archean ultramafic to mafic layered igneous intrusion, contains the J-M reef deposit, which is the world's highest grade reef type platinum group element (PGE) deposit (Zientek et al., 2002) and shows strong similarities with other world class PGE mineral systems.Yet little is known about the complex's extent under cover, and existing models ...
