Geology of the Haile Gold Mine Selected Mineral

1995-1-1  The Haile gold mine has a long and colorful history. Gold was first discovered in 1827 or 1828 as placer in Haile Gold Mine Creek. The lode sources were discovered during the early years of placer mining and activity soon shifted to shallow open-pit and underground mining. The most productive periods of mining occurred between 1888-1908 and

Origin of Mineralizing Fluids of the Sediment-Hosted

Gold is interpreted to have precipitated in equilibrium with metamorphic fluid (δ 18 O = 12–14‰ δD = −40 to −60‰) at peak metamorphic conditions of ca. 550°C and 2 kbars, consistent with isotopic fractionations between coexisting calcite, garnet, and clinopyroxene in the alteration halos. The most likely source of the mineralizing

Gold Deposits and Their Geological Classification

2016-11-20  A rational geological classification of the commonly recognized lode gold deposits is feasible if it is based on the geological settings of the deposits, host rocks, nature of mineralization and geoche m-ical signature. Sixteen common types of bedrock gold deposits are distinguished from one another and their main geological attributes are

Geology and mining — MineFacts

Gold is also extracted largely from older sedimentary placer strata and sulphide ores. The content of sulphide mineral in gold ore varies. In the Björkdal mine in Sweden, waste is produced that is reused outside the mine as road building ballast and other infrastructure. Gold ores can however also produce hazardous waste.
