Tala Hamza zinc/lead project, Algeria
Name of the Project
Tala Hamza zinc/lead project.
Location
Algeria.
Client
Terramin Australia (65%).
Project Description
The project has mineral reserves of 25.9-million tonnes grading 6.3% zinc and 1.8% lead; and mineral resources of 53-million tonnes grading 5.3% zinc and 63% lead.
An optimisation study has identified the potential to substantially increase production rates and introduce additional midgrade resources at Tala Hamza, with minimal change to the mine life and expected capital expenditure.
The study has indicated that there is potential for an additional eight-million tonnes of indicated resource to be included in production, representing an increase of about 30% of the total Tala Hamza reserve tonnage.
The study also expects a production rate increase from 1.32-million tonnes a year in the 2018 definitive feasibility study (DFS) to two-million tonnes a year in the optimisation study, with the mine life decreasing to only 19 years, compared with the 21 years suggested in the 2018 DFS.
The mining method selected is underground, using mechanised underhand drift-and-fill.
Conventional flotation will be used to recover a zinc and lead concentrate.
Metallurgical recovery is modelled at 89.6% for zinc for product at 53.8% zinc and 73.2% for lead for product at 62.6% lead.
Potential Job Creation

Net Present Value/Internal Rate of Return
The DFS estimated an after-tax net present value, at an 8% discount rate, of $303-million and an internal rate of return of 14%, with a payback of nine years.
Value
Compared with the 2018 DFS, preproduction capital requirements under the initial optimisation study have increased from $341.4-million to $360-million.
