[1] | Included in additions is the change in estimate for the decommissioning asset of $1,962 (2022: ($468))
[2] | On June 27, 2023 the decision was taken to place the Bilboes oxide mine on care and maintenance as the cost related to removing the waste and accessing the orebody could exceed the benefit from the gold revenues to be received. The impairment loss that was recognised amounted to a carrying value of $851 on impairing the Bilboes oxide asset classified under mine development, infrastructure and other. Mining and metallurgical processing continued at the Bilboes oxide mine until the end of September 2023 when the contract miner's notice period came to an end. Leaching of material that has already been deposited on the leach pad will continue while the revenue from these activities contributes to the cost of the asset. Oxide mining and processing will resume when the stripping of the waste for the sulphide project commences and can be economically justified.
[3] | Included in the 2022 impairments are development asset costs of $8,518 that predominantly relates to prospective areas above 750 meters at Blanket which are not included in the LoMP. Also included in the 2022 impairments are generator cost of $791 and loader bottom decks at a cost of $101; these assets were no longer in working condition. The carrying amount for these impaired assets were impaired to $Nil.
[4] | Accumulated depreciation and depreciation under Assets under construction and decommissioning assets include depreciation on decommissioning assets.
[5] | The solar plant was fully commissioned on February 2, 2023 and the sale agreement between Caledonia Mining Corporation Plc and Caledonia Mining Services (Private) Limited was concluded for the sale of the solar plant. Depreciation on the solar plant commenced on February 2, 2023 and the power purchase agreement, between Caledonia Mining Services (Private) Limited and Blanket Mine, became effective. From September 28, 2023 the solar plant is classified as held for sale. In December 2022, the Caledonia board approved a proposal for Caledonia Mining Services (Private) Limited (which owns the solar plant) to issue loan notes pursuant to a loan note instrument (“bonds”) up to a value of $12 million. The decision was taken in order to optimise the capital structure of the Group and provide additional debt instruments to the Zimbabwean financial market. Refer to note 30.2 for more information on these loan notes.
