Mandalay Resources Corporation presented plans to grow production at its Costerfield and Björkdal mines from 2018 to 2021. Costerfield is expected to more than double gold equivalent production over this period by bringing its high-grade Youle vein into production in late 2019. Björkdal is also expected to increase production through mining wider, higher-grade zones including the new Aurora discovery. Consolidated production is projected to increase from 81,568 ounces in 2018 to 131,000-162,000 ounces by 2021.
