Deep-South Resources

Exploring & Developing World Class Mineral Resources

Partnering with Teck

Deep-South Resources is a mineral exploration and development company. Deep-South is actively involved in the acquisition, exploration and development of major mineral properties in Africa. Deep-South growth strategy is to focus on the exploration and development of quality assets, in significant mineralized trends, close to infrastructure, in stable countries. Furthermore, in using and assessing environmental friendly technologies in the development of its copper project, Deep-South embraces the green revolution.

Deep-South holds 100% of the Haib Copper deposit in the south of Namibia. Haib is arguably the oldest porphyry deposit in the world and one of the largest in Africa. Deep-South recently disclose a PEA over the deposit and at a price of copper of $3.00 / lb, it generates an after-tax NPV of $950 million and an after-tax IRR of 30%.

In Namibia, we are guided by integrity values that keep us focused on our purpose: to turn our exploration projects into lasting reality for our empowered Namibian communities. Deep-South is committed to advancing its projects while operating in an environmentally responsible manner.

The Haib project is a large copper-molybdenum porphyry deposit located in the Karas region of southern Namibia, 8 km from the Orange River and the South African border.

The deposit is a porphyry copper-molybdenum dating from the Archean age. The Haib Cu-Mo deposit is arguably the oldest porphyry deposit in the world, which hosts easily identifiable porphyry veins and alteration. The principal mineralised hosts at Haib are a quartz feldspar porphyry and a feldspar porphyry rock. The main ore mineral at Haib is chalcopyrite, but minor amounts of bornite, chalcocite and the various green copper oxides can also be found.

The deposit hosts a 43-101 an indicated resource of 456.9 MT @ 0.31% Cu equal to 3.12 billion lbs of copper and an inferred resource of 342.4 MT @ 0.29% Cu equal to 2.19 billion lbs of copper at a cut off grade of 0.25% Cu. The resource estimation has been completed by P & E Walker consultancy and Obsidian Consulting Services, both of South Africa.

A Preliminary Economic Assessment (PEA) completed in December 2020 by Mineral Engineering and Technical Services (METS) of Australia has showed very robust economics and that the ore at haib is highly amenable to bio-assisted heap leaching. The financial metrics of one of the model of the PEA are shown in the following table:

The PEA focuses on the potential of heap leaching treatment. Several opportunities are identified in the PEA that could significantly enhance the economic return outlined in the report, including infill drilling in the higher grade area to improve the average grade of the deposit, more assays of the molybdenum to be included in future resources estimation and assess the solar power option to reduce power costs. The PEA recommends these opportunities be pursued and to proceed with a feasibility study (“PFS”).

For the recovery of copper from the Haib deposit, heap leaching was considered for all options. The primary reasons for the selection of heap leaching is the low grade nature of the deposit and the vast scale of the orebody. The low costs associated with heap leaching compared to a whole ore flotation circuit is believed to improve the viability of the project. Heap leaching is traditionally performed on oxide material, although there has been increasing development in the application to acid insoluble sulfides.

Previous bio-assisted heap leaching test work, carried out by Deep-South, Mintek, METS and SGS South Africa, have demonstrate the Haib ore can extract high amounts of copper, up to 96% Cu with a sustainable recovery on long term of 80% Cu and 82% Cu. Further test work will be conducted to optimize operating parameters.

The system design proposed will use 3 crushers and one High Pressure Grinding Rollers (HPGR). The process is designed for a 90% availability, processing 20 Mtpa at a strip ratio of waste:ore of 1.41:1.

Mineralization is open near surface and at depth to at least 800 metres deep. The Mineral Resource estimate is based on the results from approximately 66,500 metres of drilling in 196 holes. The most recent drilling data comes from Teck Resources drilling programs totalling 14,500 metres (2010 & 2014) and from re-assaying a part of the 164 historical drill cores which are well preserved on site. Indicated Resources are defined by a drill grid of 150 metres by 150 metres, while Inferred Resources are defined by a drill grid of 300 metres by 150 metres.

The Haib Copper exploration licence provides significant potential for resource expansion, since there is known, but poorly drilled and assayed, mineralisation beyond the drill grid boundaries and below the main mineralised body (which covers some 2 square kilometres of surface area), where a few drillholes from 75m above mean sea level to -350m above mean sea level (i.e. a thickness of 425m) have shown that mineralisation is present. The deepest drillhole did not pass out of mineralised material. In addition, there are 5 satellite mineralised target areas surrounding the main Haib porphyry body which still require further evaluation.

The results of the previous exploration programs have showed that the resources could be expanded by drilling under the current mineral resource and into 5 newly discovered satellites to the main body. Furthermore, the results from the recent Preliminary Economic Assessment (PEA) have been promising and METS recommends to Deep-South to conduct a Pre-Feasibility Study (PFS) as the next phase of the project.

Deep-South plans to start the PFS during Q2 2018, which will include drilling in the main body to increase the level of the resource to measured or probable reserves, metalurgical and process technologies tests and enviromental studies.

Management hopes the outcomes of a Pre-Feasibility Study for the Haib Project will support the following:

  • An assessment of the likely technical and economic viability of the opportunity within a 25% level of accuracy;
  • Optimization of the different mining, process, location and project configurations to determine and recommend the preferred optimum to be engineered during the Pre-Feasibility Study;
  • Evaluation of the project at different capacities;
  • Determination of any fatal flaws in the opportunity;
  • Development of the risk profile of the opportunity in relation to the key business drivers;
  • Determination of the nature and extent of the Work Plan to complete further geological, mining, metallurgical, environmental and marketing work needed to be completed or undertaken during the Feasibility Study;
  • An estimate of the costs, schedule and resources required to complete the Feasibility Study.  In addition, an overall project schedule shall be prepared to indicate the overall timing of project implementation, commissioning and start-up, and ramp-up to full production;
  • Identify resources (internal and external) and services required to undertake further work on the opportunity;
  • If a Pilot plant is required, it will be implemented during this stage;
  • Upgrade the mineral resource (if required);
  • Stakeholder considerations and plans;
  • Risk assessment further refined and mitigation plans established and;
  • Environmental assessment to prepare an environmental impact study.

Initial Company Report Q1, 2021 Explains Why Deep-South is Extremely Undervalued Copper Play

Deep-South Resources is now in the process of advancing the Haib Copper Project towards a feasibility study with plans to complete a 12,000m infill drill program to expand the already impressive resources even further.

Interview with Deep-South Resources CEO Reveals Massive Potential in Copper Space - Smallcaps Investment Research

CEO highlights the results of a recently updated PEA for Haib that shows an after-tax NPV of US $1.3 billion and an after tax IRR of 42.1% at a copper price of $3.50 per lb. Of note, the current market capitalization of Deep-South Resources is only 1.8% of this NPV. Moreover, there’s a very realistic potential to expand Haib’s resource. At the moment, the resource has been estimated from surface to 350 meters deep, while some holes that were drilled as deep as 800 meters, still show copper mineralization.
