Gold in Maine. Gold occurs in several geologic environments in Maine: in bedrock, in sediments that were eroded from bedrock by glaciers, and in stream deposits derived from either of these sources. Veins of gold in bedrock are called "lode" deposits, and "placer" deposits are concentrations of gold that accumulated in unconsolidated sediments.
Each deposit contains several different types of ore, varying in both grade and physical properties. Its existing resource totals over 300Mt grading 51% Al2O3, sufficient to support production at current rates for at least 25 years. Historically, grades in Sangarédi have been 56–58% Al2O3, while ore in Bidikoum averages 50% and Silidara 52%.
