Resource Debate in Southwest Alaska: The Bristol Bay Fishery and the Pebble Mine
… a plan to develop a low-grade, but substantial, mineral deposit that consists primarily of copper, gold, and molybdenum. The estimated value of the minerals present is more than $500 billion. This plan is known as the Pebble Project, and could involve an open-pit mine, a large area of block …

Structural Controls of the San Emidio Geothermal System, Northwestern Nevada
… leaching and bleaching, native sulfur deposits, and boiling groundwater at depths less than 100 m, suggest, however, that the San Emidio geothermal resource extends several kilometers northward from the currently producing well field. Thermal anomalies identified along this fault zone …

Trace Elements and Sulfur Isotope Variations in Endowed and Non-Endowed Porphyry Systems of the Dawson Range Mineral Belt, Yukon Territory
The Dawson Range Mineral Belt (DRMB) in the Yukon Territory is a geologically complex region with significant potential for critical mineral exploration. This study addresses the challenges of exploring this area, focusing on select trace elements and sulfur isotope analyses to distinguish between …

‘Oil that harvests culture’: state, oil and culture in petrosocialism (Venezuela, 2007-2013)
… to be extracted, exploited and processed like a mineral resource. An original contribution of this thesis is to build on Yúdice’s expediency of culture as a resource to propose the notion of culture-as-mineral deposit, in which culture is inextricable from land, akin to ‘renewable oil’ and …

The Evolution of the Los Negritos Porphyry Copper Deposit, Coquimbo, Chile: Geological, Geochronological, Mineralogical and Geochemical Evidence
The Los Negritos porphyry copper deposit is located ~ 4 km to the northeast of Carmen de Andacollo Mine in the Chilean Cretaceous metallogenic belt. The mineralization is hosted in andesite of the Quebrada Marquesa Formation and a series of at least four early to intramineral porphyry intrusive …

Evaluation of Existing Subsurface Cooling Systems Worldwide and Development of Efficient Cooling Methods and Systems Based on Renewable Energy Sources
As relatively hot mineral deposits are being developed to considerable depth, the issue of mitigating heat will require substantial cooling capacity in some cases. For deep deposits to be mined at increasing depths, mechanical cooling systems used to maintain an acceptable underground climate will …

An investigation into the impact of residual reagents on flotation in response to process water recirculation
In the mineral pulp phase of the flotation process, water makes up about 80-85% of the constituents, thus making water an important component. The increasing scarcity of water has resulted in greater environmental restrictions which have led to the necessity of mine operations recycling water from …

White mica: spectrometer design, district-scale mapping, and integration of imaging spectrometer and lidar data
… to the study of white mica in the context of mineral exploration and mining. The dissertation comprises three parts: 1) spectrometer design, 2) district-scale mapping, and 3) integration of imaging spectrometer and lidar data. White micas are common products of hydrothermal alteration …

History of the fluids associated with the lode-gold deposits, and complex U-PGE-Au vein-type deposits, Goldfields Peninsula, Northern Saskatchewan, Canada
The varied mineral deposit types of the Beaverlodge area, Northern Saskatchewan, indicate that the rocks have undergone a complex and protracted fluid history. All of the deposits studied are physically hosted in a variably metamorphosed sedimentary sequence, the Aphebian-aged Murmac Bay Group …
