Westgold Resources Limited Annual Report 2021

9 Westgold Resources Limited Annual Report 2021 While Big Bell is the primary producer of ore to the Tuckabianna mill, the Comet underground mine has served well as a supplementary source and is expected to continue as such in FY22. After three years of de- watering, mine rehabilitation and refurbishment, Big Bell mine production began to rise in FY21 with steady state operations expected to be achieved in FY22. A number of open pits commenced at CGO in FY2021 including a new mining hub at Cuddingwarra North and open pits at Jim’s Find and City of Chester. Exploration and viability studies were carried out during FY2021 at the previously mined Fender open pit mine on the southern limits of the Big Bell shear, testing the economics of a transition to underground operations with this potential development scheduled to commence during FY22.
