Mineralogy And Geochemistry Of The Heddleston Porphyry Cu-Mo Deposit, Montana, Ben Schubert
Graduate Theses & Non-Theses
The Heddleston porphyry Cu-Mo deposit is located in Lewis and Clark County, Montana, near the headwaters of the Blackfoot River. It is immediately west of the historic Mike Horse mine, an important producer of Pb-Zn from polymetallic veins and lodes. The Heddleston property was explored extensively by the Anaconda Company in the 1960s and 1970s, but was never mined. Specimens of polished drill core from the deposit are archived in the Anaconda Research Collection at Montana Tech campus. The purpose of this research project was to use the archived samples to examine the geochemistry and mineralogy of the Heddleston and …

Naturally Occurring Acid Rock Drainage In The Anaconda-Pintler Mountain Range, Montana: A Case Study Of Geochemistry In Two Streams Flowing From Mount Evans, Margaret Doolittle
Graduate Theses & Non-Theses
Mount Evans is located in the Anaconda-Pintler mountain range of southwest Montana approximately 22 km southwest of Anaconda, Montana. Mount Evans appears reddish orange on Google Earth amongst the rest of the mountain range which is a grey white color, indicating the presence of limonite staining and probable sulfide mineralization. In addition, two streams draining opposite sides of the mountain, and either side of the continental divide have conspicuous white coatings on boulders that are clearly visible with Google Earth. During a mineral resource assessment in the 1980s, the USGS suggested that the Mount Evans area could be the top …
