The Central Shaft project has been in progress since early 2015, with Caledonia spending some $44 million sinking a new shaft from surface to a depth of over 1,200 m. Sinking of the shaft was predicated on increasing gold production to 80,000 oz/y of gold, compared with 54,512 oz produced in 2018 and the 53,000-56,000 oz expected in 2019.
