[1]Included in additions is the change in estimate for the decommissioning asset of ($868) (2023: $1,962) due to change in the Life of Mine (“LoM”) estimate to 2041.[2]Accumulated depreciation and depreciation under Assets under construction and decommissioning assets include depreciation on decommissioning assets.[3]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 21.1 for more information on these loan notes. | |
