This presentation is an updated review of the economic geology at Mount Pleasant based upon our recent exploration results. There has been a resurgence of interest in these deposit types with the recent recovery of W, Mo, and Sn metal prices. Economic interest in the Mount Pleasant deposits has been heightened due to its hosting of metals that are increasingly important in high technology applications and medicine, such as indium and bismuth.

Economic geology is the study of the origin and distribution of mineral deposits of metals, other useful materials (such as building stone and salt), and fossil fuels (petroleum, natural gas, and coal). The economic geologist explores for these materials, predicts the mineral reserves of known deposits, and assesses the economics for the extraction of the ore. For instance, for an iron ore deposit, the geologist needs to assess the kinds and amount of iron minerals present, the depth of the deposit, the location of the deposit, and the ownership of the land so that estimates for the possibility of mining the iron ore profitably may be made.
