<<..In conclusion he reports that PT is the primary precious metal. "The Oro Grande property is a Pt-Au occurrence in a previously unrecognized and favourable setting. It has unqestionably highly anomalous PT values and very favourable Pt/Pd ratios in several rock types in a brecciated hydrothermally altered mafic complex which is presumed to be underlain by a younger pluton. The property deserves serious attention."..>> Not all Plutons were Granitic in composition makeup. Some -Gabbo rather than basaltic. Gabbro is also crystallising to form constructive plate boundries ...ie magmatic chambers within which these oceanic gabbros crystallise are ten ( 10 Folks) or more kilometers ( mult by .67 to get a mile or divide/ 2.0ish factor ) WIDE!!! !
