The shovel ready Eagle Gold Project is the most advanced project in the region and is on track to be the largest gold mine in Yukon history. The proposed Eagle gold mine will produce doré from a conventional open pit operation with a threestage crushing plant, invalley heap leach and carboninleach adsorptiondesorption gold recovery plant.
The two most recent main levels in Kiruna and Malmberget are the deepest vertical mines in LKAB's history, and the mining methods used to achieve these depths are the most hightech in the world. Vertical mining means mining ore at new depths below previous main levels, because the mineral resources above have been exhausted.
The early attention paid to mining focused on gold and silver discoveries. However, later, discoveries of industrial minerals like coal, copper, iron, oil, and gas, stimulated new and continued growth of settlements in the west.
