Caledonia Mining Corporation Plc Record Annual Production at Blanket Mine and Guidance for 2023

ST HELIER, Jan. 13, 2023 - Caledonia Mining Corporation plc ("Caledonia" or the "Company") (NYSE AMERICAN: CMCL; AIM: CMCL; VFEX: CMCL) announces quarterly and annual production from the Blanket Mine in Zimbabwe ("Blanket") for the quarter and year ended December 31, 2022. The Company also provides guidance for the year to 31 December 2023 in respect of production, on-mine costs and capital expenditure at Blanket and at the Bilboes oxides project. All production numbers for 2022 are expressed on a 100 per cent basis and are based on final assays from the refiner.

Production Highlights

• Record gold production in 2022 of 80,775 ounces which exceeded the top end of the Company's guidance and achieved its long-standing production target.
• 2022 annual production represents a 19.7 per cent increase on the 67,476 ounces produced in 2021.
• Quarterly gold production of 21,049 ounces, a 13.1 per cent increase on the 18,604 ounces produced in Q4 2021.
  

2023 Guidance

Production from Bilboes Oxides

The Bilboes oxides project is a small-scale, two-to-three-year project which entails the stripping of overburden to a depth of approximately 40 meters to expose the oxidized material which will be processed on-site using an existing heap leach facility which has been in operation for the majority of the past decade. Ore production from the Bilboes oxides project is expected to start in mid-February and we anticipate recovering gold from the heap leach from March. The project had an initial capital requirement of approximately $540,000, which was expended in 2022. The operational costs to remove the overburden and the oxide material will be expensed as they are incurred. The stripping of the overburden would have been required in due course to implement the larger sulphide project and hence these costs would have been incurred in any event.

Capital Expenditure

Capital expenditure at Blanket in 2023 includes approximately $9.6 million in respect of a new tailings facility (reflecting tightened regulatory requirements) and a further $9.8 million of deep-level capital development so that operations can be maintained in future years. In 2023, it is expected that approximately $2 million will be incurred in the preparation of a revised feasibility study for the larger sulphide project at Bilboes. It is anticipated that the cost of the projected capital expenditure for the group will be met from operating cashflows and in-country borrowings.

Commenting on the announcement, Mark Learmonth, Chief Executive Officer, said:

"In 2014, Caledonia announced a plan to sink a new shaft (Central Shaft) to 1,200 metres from surface, all funded through internal cash flow, with a long-term target of achieving an annual production rate of 80,000 ounces. I am delighted to announce today that we have now achieved this target, with 2022 annual production of 80,775 ounces - just over the top end of our guidance. This achievement is a huge milestone for the Company; it has been a tremendous team effort and I would like to thank all of our employees for their continued hard work.

"Production guidance for 2023 assumes that Blanket will broadly maintain the production rate achieved in 2022. 2023 guidance also includes the estimated production from the small oxides project at Bilboes where mining activity is expected to commence in February, and we expect to extract gold from the heap leach process in March.

"Cost guidance at Blanket and Caledonia (i.e. excluding the costs of the Bilboes oxides project) is consistent with the costs we have historically incurred. We anticipate that the inflationary pressures currently being experienced by most mining companies will be offset by efficiencies resulting from the successful implementation of Central Shaft. At the consolidated level, the all-in sustaining cost per ounce is also expected to benefit from the lower cost of electricity due to the recently installed solar plant.

"The on-mine cost of the small oxides project at Bilboes reflects the low grade of the oxide material. The oxides project is not expected to be representative of the much larger sulphide project at Bilboes in terms of grade, production levels or cost profile. Nevertheless, the oxides project is expected to contribute to the group's cash generation whilst at the same time allowing us to pre-strip to the deeper sulphide material.

"Over the last 18 months the Company has built an attractive portfolio of assets with the acquisitions of Bilboes, Motapa and Maligreen. Blanket will continue to serve as a solid foundation for this growth, as we look to progress our assets with our long-term goal of becoming a multi asset gold producer."
