[4] | On July 6, 2020 the Board appointed Voltalia as the contractor for the engineering, procuring and constructing of a solar plant to be owned by a subsidiary of the Company and supply Blanket Mine with power. 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 of the 12MWac solar plant is expected to be completed in the second quarter of 2022. Included in Prepayments is an advance payment to Voltalia to the amount of $1,821 in terms of the EPC agreement and $704 for equipment. These items were delivered at the date of approval of these consolidated financial statements. Also included in Prepayments is an amount of $426 to entities in Zimbabwe for civil and construction work related to the solar plant. Refer to note 21.
