Abstract : The St Austell Granite, located in southwest England, represents a geologically significant area for the study of lithium-bearing micas and their mineralization potential. This paper investigates the geochemical properties, spatial distribution, and extraction feasibility of lithium from micas, such as zinnwaldite and lepidolite, which are hosted within this granite complex. Through a combination of field sampling, petrographic analysis, and advanced geochemical characterization techniques, the study explores the factors influencing lithium enrichment, including magmatic processes and hydrothermal alterations. The findings reveal that the lithium-bearing micas in the St Austell Granite possess high concentrations of lithium, often associated with rare earth elements, making them a promising resource for sustainable lithium extraction. Moreover, the research highlights the environmental and economic implications of developing these deposits, particularly in the context of increasing global demand for lithium in energy storage technologies. This study contributes to the growing body of knowledge on unconventional lithium sources, providing insights into their viability as a strategic resource for the renewable energy transition. Key recommendations for future exploration and processing strategies are proposed, emphasizing the role of innovation in unlocking the full potential of lithium- bearing micas in the St Austell Granite.

Keywords : Lithium-Bearing Micas, St Austell Granite, Mineralization Potential, Geochemical Analysis, Sustainable Lithium Extraction.
