Completion of Definitive Feasibility Study (DFS) and approval of Environmental and Social Impact Assessment (ESIA) were achieved in March and April 2016 respectively. An optimised feasibility study (OFS) was produced in January 2017. Kalana was planned as an a open pit operation with a mine life of 18 years. Average gold production was estimated at 101koz/a. Since taking over the project, Endeavour Mining has launched an optimisation study on the previous DFS, looking at the option of expanding the plant capacity to increase average annual production and shorten mine life. The updated feasibility study is expected to be completed by end-2019 and construction to commence in mid-2020.
