The 2013 conference of the Society for Mining, Metallurgy & Exploration (SME) is right around the corner — tech sessions will be held in Tucson on December 9.
M&A’s Jon Whittier will present a talk on an interesting mining hydrology project that involved characterizing a lithium and potassium brine deposit (the Sal de Vida) within the high-elevation Salar del Hombre Muerto in the Andes of northwest Argentina. Whittier and colleagues Mike Rosko and Ed Peacock assessed not only the hydrologic characteristics of the host aquifer but also the grade distribution of the brine deposit. Their goal was to develop resource estimates (inferred, indicated, and measured) over the planned production period for Galaxy Resources Limited. These estimates needed to account for the dynamic nature of the extraction process; because brine is a fluid that moves through the aquifer, changes in grade occur once when pumping begins and continue throughout the production period.
