The most recent production data were publicly available for 2016 (as of May 24, 2021).
Metallon has been forced to put its mines on care and maintenance because of the unsustainable costs of running them without proper compensation for its proceeds from the Government of Zimbabwe. Where payments were received, they would only amounted to a third of the total owed. Between 2016 and 2019, Metallon lost US$82m and Metallon is claiming for US$132m for the lack of profit and procurement, including interest. |

Summary:
How Mine is situated in the Bulawayo greenstone belt and exploits several individual mineralised pods situated within a sigmoidal structure which dips at 70° to 80° west. The pods are broadly cigar-shaped bodies comprising zones of enhanced hydrothermal alteration and gold mineralisation that plunge steeply. Mineralisation within the orebodies consists predominantly of pyrite (>90%) with minor chalcopyrite and pyrrhotite and is associated with silicification and carbonation. Gold is found in contact with the sulphides, often in fractures, although there is also some free gold. Some silver occurs with the gold, increasing from 4% to 8% of gold as mining progresses down-dip.
Summary:
The current hoisting capacity is 35ktpm. The average mined grade is 5g/t Au.
