The Carlin Trend is a significant gold mining district located in northeastern Nevada, USA. It is known for its large, low-grade gold deposits that are primarily found in sedimentary rock formations. The trend was discovered in the 1960s and has since become one of the richest gold-producing areas in the world, contributing a substantial portion of Nevada's gold output. The geology of the Carlin Trend is characterized by unique features such as high levels of arsenic and the presence of certain types of mineralization. Mining companies, including Barrick Gold and Newmont Corporation, have extensively explored and developed the area, utilizing advanced extraction techniques to efficiently recover gold from the ore.
