Name and Location
Konongo gold expansion project, Ghana.
Project Description
The Konongo gold project comprises a mining licence and prospecting licence covering 192 km2 in the Ashanti Gold Belt of Ghana. The plan is to develop the project into a 100 000-plus-ounce-a-year gold producer.
An internal scoping study has indicated that the mine's yearly gold output could be increased to between 40 000 oz and 60 000 oz, at head grades of between 2 g/t and 3 g/t, by increasing plant throughput to 700 000 t/y. The proposed expansion is based on the purchase and installation of a semiautogenous mill or ball mill to operate in circuit with the existing ball mill. Additional tankage will be added to the leach circuit to increase capacity, while maintaining the same residence time.
The expansion will be centred on the existing 350 000-t/y carbon-in-leach plant on site and is, therefore, dependent on the successful refurbishment of the existing plant.
Value
The scoping study indicates that increasing the plant throughput to 700 000 t/y can be done with relatively modest capital expenditure of between $3-million and $4-million.

Since no serious equipment defects have been identified in the works to date, Signature Metals plans to start a prefeasibility study on the expansion of the plant with confidence.
