Name of the Project
Haib copper project.

Location
The project is partially located in the Namaqua-Natal province, in Namibia, called the Richtersveld geological subprovince.

Project Owner/s
Mineral explorer and developer Deep-South Resources, through its subsidiary Haib Minerals.

Project Description
An updated preliminary economic assessment (PEA) has shown the Haib project to be amenable to bioheap-leaching.

The PEA envisages a life-of-mine of 24 years and a throughput of 20-million tonnes a year, with copper recovery estimated at 80%, and production estimated at 35 332 t/y of copper cathode and 51 081 t/y of copper sulphate.

The mine design is based on openpit methods. As the deposit comprises hard-rock material, the mining operations will involve the drill and blast of all excavated material, which will be segregated by cutoff grade.

The mining fleet will consist of appropriately sized hydraulic excavators and off-highway dump trucks, supported by standard opencut drilling and auxiliary equipment.

There will not be any tailings. The spent heaps will be rehabilitated and left in place. Owing to environmental reasons and water resources, the tailings from the pH adjustment process and the iron removal process will be disposed onto the spent heaps using filtered dry-stacked tailings.

Potential Job Creation
Not stated.

Net Present Value/Internal Rate of Return
The project has a pretax net present value, at a discount 7.5% rate, of $977-million, and an internal rate of return 30.1%, with a payback of 4.22 years.

Capital Expenditure
Capital expenditure is estimated at $341-million.

Planned Start/End Date
Not stated.

Latest Developments
Namibia's Ministry of Mines and Energy has renewed Deep-South Resources' Haib copper licence for two years.

This follows a lengthy court battle, which ended with the High Court of Namibia ordering the Ministry in March 2023 to restart Deep-South’s licence renewal application procedure. The Ministry had, in June 2021, informed the company that it would not renew the licence.

Preparations have started on the work programme and on the resumption of the project development as soon as possible.

Key Contracts, Suppliers and Consultants
