Summary

Sulfide- and chromite-bearing samples of the Basal and Ultramafic series of the Stillwater Complex are known to contain elevated concentrations of chromium, nickel, copper, cobalt, gold, and platinum-group elements (PGE). Drill core and surface samples were collected from the Chrome and Iron Mountain areas for whole rock geochemical analysis, with specific interest in PGE, cobalt, and gold concentrations. Core samples are from exploration drilling programs by AMAX in the 1960s and 1970s and Beartooth Platinum in 2004-2007. Reported whole rock data were measured using the following methods: major elements by wavelength dispersive X-ray fluorescence (WDXRF), 60 trace elements by inductively coupled plasma-optical emission spectrometry [...]

Purpose

This work was completed in support of the project, Critical Commodity Studies: Stillwater Complex, Montana. The purpose of this research was to understand the process(es) responsible for contact-type Ni-Cu-PGE mineralization in the Basal and Ultramafic series of the Stillwater Complex and compare with other known deposits with contact-type mineralization (for example, the Duluth Complex in the Midcontinent region).
