The demand for Rare Earth Elements (REE) and Platinum Group Elements (PGE) in advanced technologies and clean energy has highlighted concerns about China's dominance in the REE market. To reduce dependence on foreign mineral supplies crucial for national security and the economy, the United States has sought to enhance its geological knowledge and identify undiscovered critical mineral resources. This thesis focuses on the north-central region of the Yukon-Tanana Uplands in Alaska, a region of profound geological intrigue, holding the potential for significant critical mineral resource deposits. It employs advanced geochemical mapping techniques and Exploratory Data Analysis (EDA) to assess this potential with geochemical data provided by the Earth Mapping Resources Initiative (Earth MRI), carried out by the United States Geological Survey.
