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.”
