Canada is one of the world’s major gold producing countries and is known for its greenstone gold deposits. Since the 1980s, new progress has been made, especially in the upper part of the Greenstone belt. Lopin gold deposit in iron construction related to turbid current deposition in the Upper Arnault of the Late Archean granite-greenstone belt in the Slavonic tectonic province of the northwestern part of the shield, and formal mining and mining in the early 1980s , And is today one of Canada’s major gold mines, which not only adds new types to the greenstone gold mine, but also increases gold production in the Wawa granite-greenstone In the upper Goliath volcano-clastic sedimentary formation, the pyrite-dominated Hemlo gold deposit was discovered, which, on a massive scale, sensationalized
