Highlights

• Measured and Indicated Mineral Resources of 8.03 million tonnes at a grade of 1.71g/t containing approximately 442 thousand ounces of gold²
• Inferred Mineral Resources of 6.17 million tonnes at a grade of 2.12g/t containing approximately 420 thousand ounces of gold²

Table of Mineral Resources

Caledonia will continue to evaluate the potential of Maligreen with a view to developing the project within the context of the Company's project pipeline taking strategic priorities into account, specifically the recently announced Bilboes project, also located in the Zimbabwe Midlands, which is a far more advanced project.

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

"We are pleased to announce an upgrade to the Mineral Resources at Maligreen. Today's announcement which improves the geological confidence of approximately half the Mineral Resources from Inferred to Measured and Indicated Mineral Resources supports our confidence in the project and its geological prospectivity. We expect to continue our evaluation work on the project, in line with other strategic and capital priorities for the business into the future as we build an attractive project and exploration pipeline in Zimbabwe."

² The following assumptions were applied in estimating the Mineral Resources:
1 - Gold price of USD1,800/oz used to determine cut-offs
2 - Mineral Resources have been depleted for surface mining that has occurred
3 - Mineral Resources cut-off of 0.4g/t Au for open pit (<220m below surface) and 1.5g/t Au for underground (>220m below surface) was applied
4 - Densities utilised were 2.57 t/m³ for oxide and transitional and 2.65 t/m³ for sulphide material
5 - Geological losses applied of 5% for Measured, 10% for Indicated and 15% for Inferred Mineral Resources
6 - Mineral Resources reported as total Mineral Resources and are not attributed
7 - All tonnages are reported in metric tonnes and gold content conversion calculations based on a conversion of 1kg = 32.15076 oz
