On 1 June 2015 Barberton Mines entered into an agreement with the Barberton Mines BEE Company Proprietary Limited and Barberton Mines BEE Trust.
The agreement concluded Barberton Mines would issue 5% of its authorised share capital for ZAR99.5 million to Barberton Mines BEE Company Proprietary Limited which is 100% held by the Barberton Mines BEE Trust.
The benefi ciaries of the Barberton Mines BEE Trust are all the Barberton Mines employees of a Paterson Grading C level and below.
The share issue was vendor fi nanced by Barberton Mines against preference share capital issued by Barberton Mines BEE Company for ZAR99.5 million. Employee share ownership plans (ESOP).
Summary:
Modelling and geological profiling of the boreholes confirmed two distinct geographical populations across the BTSF. This is the result of historical deposition that took place in two separate compartments, a higher grade BIOX® tail section and a lower grade concentrator/flotation tail section.
Processing Technologies
- Carbon in leach (CIL)
- Solvent Extraction & Electrowinning
- Cyanide (reagent)
Summary:
The BTRP has been designed to treat tailings through a Carbon in Leach circuit using electro-winning and smelting to produce a saleable product.
