Neither are much help in defining an ore reserve on a small hydrothermal deposit and perhaps it is foolish to try.
Numerous studies of Au-PGM deposits and laboratory research on the thermochemistry of PGM solubility, transport, and deposition since that time have shown that Au-PGM occur in a variety of hydrothermal deposit classes, including porphyry coppers, fracture-shear zone hosted, and sediment hosted.

NASA's Mars Reconnaissance Orbiter (MRO) spacecraft has been circling the red planet since March 2006, and it found large hydrothermal deposits in the Eridania basin - a region in southern Mars that was once filled by a sea with about 50,000 cubic miles of water and now has some of the oldest exposed rocks on the planet's surface.
