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.
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

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

Latest Developments
In the ongoing court case pertaining to the Ministry of Mines and Energy of Namibia’s refusing to grant Deep-South Resources a licence for its Haib copper project, the miner reports that, although the Ministry filed additional documents as part of the review record, these did not provide any evidence supporting the Ministry’s decision.
This follows the failure of the Ministry’s legal counsel earlier this month to file its defence affidavit for the refusal to grant the prospecting licence EPL 3140.
A High Court judge previously granted an extension to the Ministry to file the documents it stated it had recently discovered and that were not part of the record of proceedings.
However, the Ministry had until only March 11 to complete its filing.
In a statement, Deep-South notes that the documents filed by the Ministry on March 11 were copies of documents contained in previous filings or pertaining to previous licence tenures.
