* | Included in additions is an amount of $15,771 ( 2019: $14,051, 2018: $19,323 ) relating to capital work in progress (“CWIP”) and contains $53 ( December 31, 2019: $165, 2018: $61 ) of borrowing costs capitalised from the term loan. As at year end $85,479 of CWIP was included in the cost closing balance ( 2019: $69,708, January 1, 2019: $55,657 ). On July 6, 2020 the Board appointed Voltalia as the contractor for engineering, procuring and constructing a solar plant to be owned by a subsidiary of the Company. All solar costs that were incurred before July 6, 2020 were accounted for as other expenses and accounted through profit or loss. Solar costs incurred after approval by the Board are accounted for as Property, plant and equipment as it became clear and probable that future economic benefits will flow to the project. The 40 -hectare site for the project has been cleared and fenced and is ready for civil work to commence. Construction on the 12MWac solar plant is expected to be completed in April 2022.
~ | The Group voluntarily changed its disclosure policy for exploration and evaluation assets to be disclosed separately as Exploration and evaluation assets rather than as part of Property, plant and equipment (refer to note 4 (b)(i)). The new disclosure policy was adopted from December 10, 2020 and has been applied retrospectively.

Economic recovery Items of property, plant and equipment are depreciated over the LoMP, which includes planned production from inferred resources. These inferred resources are included in the calculation when the economic recovery thereof is demonstrated by the achieved recovered grade relative to the mine's pay limit for the period 2006 to 2018. The pay limit has ranged from 2.10 g/t in 2019 to 2.10 g/t in 2020 while the recovered grade has ranged from 3.26 g/t to 3.38 g/t over the period. All-in-sustaining-cost # has remained consistently below the gold price received over this period resulting in economic recovery of the inferred resources.
# |  | All-in sustaining cost (“AISC”) per ounce is calculated as the on-mine cost per ounce to produce gold (which includes production costs before intercompany eliminations and exploration costs) plus royalty paid, additional costs incurred outside the mine (i.e. at offices in Harare, Johannesburg, London and Jersey), costs associated with maintaining the operating infrastructure and resource base that are required to maintain production at the current levels (sustaining capital investment), the share-based expense arising from the LTIP less silver by-product revenue and the export credit incentive.
