The most recent production data were publicly available for 2016 (as of January 16, 2020).
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. |

Gold Fields of Shamva is the parent company of Shamva Mine.
Summary:
Shamva Mine is situated in the Shamva greenstone belt and exploits numerous orebodies which occur within a 300- to 400-m wide Riedel-type shear system. The sub-vertical orebodies are indistinguishable from the host rocks. Mineralisation within the orebodies consists predominantly of pyrite (>90%) with minor sphalerite, galena, chalcopyrite, pyrrhotite and arsenopyrite. Gold is found in contact with the sulphides, often in fractures, and varies significantly in grain size with visible gold commonly intersected in development and underground drilling. Silver occurs with the gold and represents some 50% of gold content.
Summary:
The current hoisting capacity is 45ktpm. The average mined grade is 3g/t Au.
Processing Technologies
- Gravity separation
- Carbon in solution (CIS)
- Carbon in pulp (CIP)
Summary:
The ore is processed through a single metallurgical facility that uses a combination of crushing, milling, gravity recovery and combination of carbon-in-solution and -pulp processes.
The current milling capacity is 33ktpm.
