The Republic of Katanga Mining Projects

A wide-ranging grassroots exploration program for new major copper deposits is available in the Republic of the Katanga.

Kibamba Prospect, Republic of Katanga

On March 27, 2006, a new discovery at its Kibamba copper prospect in the Republic of Katanga. A total of the 25 reverse circulation drill holes totalling 2,430 meters and 9 diamond drill holes totalling 1,863 meters were drilled between October and December 2005. Highlights from the 25 hole drill program included 80 meters grading 2.20% copper and 0.25% cobalt.


The proposed US$300 million Kolwezi Tailings project in The Republic of Katanga has been a long time in gestation and at times it has seemed that it might never get off the ground. But the project – which could transform the decaying Kolwezi area in the Republic of Katanga and also provide encouragement to other potential investors – has gained considerable momentum.

The main impediment to the Kolwezi project has never been the quality of the resource, which is generally regarded in mining circles as having the potential to support a longlife, low-cost cobalt and copper operation.

Kolwezi would be viable at prices well below those now being seen in the marketplace.
The resource which underpins the project consists of stockpiled flotation tailings, which were produced by the mineral concentra-
tor in Kolwezi (the historic mining centre of the Katangan portion of the Central African Copperbelt) which processed high-grade ore
from the KOV and other mines in the vicinity from the early 1950s onwards. Due to the poor recoveries obtained from the conventional
concentrating techniques used, valuable amounts of copper and cobalt were discharged into two tailings dams known as Kingamyambo and Musonoi. The two dams contain 112,8 Mt of oxide tailings grading a remarkable 1,49 % copper and 0,32 % cobalt, as estimated by Dr Isobel Clark of Geostokos.

Musonoi is by far the bigger resource with 70 Mt of material but is difficult to mine in the wet season.

Musonoi, because of the wet season problems, would be active for only nine months of the year once it does kick in.
The slurry created will be sent to a processing plant incorporating leaching and SX/EW facilities which will produce LME grade
copper cathode and high purity cobalt metal. The project is expected to produce initially 5 500 tonnes of cobalt and 30 000 tonnes of copper annually, at which level of output it has a mine life in excess of 50 years. The metallurgical process is complex and untested at full-scale level but all the sub-systems use proven technology. In addition, the process route has been tested extensively at pilot plant level.

Kolwezi could produce at a much higher rate, but this could impact on the cobalt market. The trick really is to strike a balance – on the one hand, we need a big enough operation to give us economies of scale, but on the other hand we don’t want to destabilise the cobalt market, which is known for its volatility. Annual demand is roughly 50 000 tonnes, so even at a production of 5 500 tonnes Kolwezi is going to be a very significant player in the market.”

In terms of infrastructure, the town of Kolwezi is reasonably well served. Along with Lubumbashi and Likasi, it is one of the major centres in Katanga, with both road and rail links (although the road needs upgrading) to Lubumbashi (and hence to Zambia and South Africa) and plentiful power in the form of hydro schemes.

Tenke Fungurume Mining Project

The Tenke Fungurume copper-cobalt deposits comprise one of the world's largest, richest known copper-cobalt resources and are in the process of being developed into a large scale, long-life mine demonstrating low operating costs. The Tenke Fungurume mineral concessions still remain extensively under-explored.

The deposits are located within multiple adjoining concessions totalling in excess of 1,500 square kilometres in Katanga at approximately latitude 10°S and longitude 26°E. Tenke Fungurume is about 175 kilometres northwest of Lubumbashi, the Republic of Katanga capital and administrative centre, and  largest city of the country.

Current Development Plans

The Feasibility Study has been completed for the first phase of production at the Tenke Fungurume copper/cobalt project in Katanga. The target for first copper cathode production is the second half of 2008.

The Feasibility Study is based on standard African Copper Belt process technology with optimization from Phelps Dodge as one of the world leaders in solution extraction and electrowinning operations. Overall metal recoveries are expected to be 95% for copper and 83% for cobalt metal. Mill facilities are expected to process approximately 7,000 metric tpd of ore.

Facilities have been designed to initially produce approximately 115,000 metric tonnes per annum ("tpa") of London Grade A quality copper cathode and 8,000 tpa of cobalt in any combination of cobalt metal or intermediate cobalt hydroxide. Site infrastructure and process facility layouts have been designed contemplating significant future potential expansions.

There are extensive resources on the concessions that are not included in current mine plans as well as many untested target zones. Mixed and sulphide mineralisation is known to extend over 500 metres below surface in the areas tested to date. Mineralization in the area is known to have a strike length of up to 80 kilometres.

The 40-year mine plan is based on first developing the Kwatebala, Fwaulu and Goma deposits. Proven/probable ore reserves developed by Phelps Dodge to U.S. SEC standards1 for these three areas are 103 million metric tonnes, grading 2.1% copper and 0.3% cobalt (proven 22 million tonnes grading 2.2% copper and 0.30% cobalt, probable 81 million tonnes grading 2.1% copper and 0.31% cobalt). The Feasibility Study is based on approximately 19 years of fresh ore processing followed by 21 years of lower-grade stockpile feed. During the first 10 years, 25.5 million tonnes of leachable oxide ore is processed grading 4.57% copper and 0.37% cobalt. The overall strip ratio is 3.1:1. Drilling continues across the concession, and it is our belief that the mine plan will evolve significantly as additional material is expected to be brought into the proven/probable category.

The mining method will be open pit, utilizing conventional methods in waste and a continuous miner in ore to maximize operating efficiencies and to minimize dilution of the high-grade material. Haulage will be by articulated 45-tonne trucks.

Exploration potential across the Tenke Fungurume concessions is extensive, and a significant drilling program is in progress to potentially add proven/probable, high-grade ore reserves to the mine plan and for a potential major plant expansion in the early years of the project.

During 2006, approximately 16,000 meters of drilling was performed under the direction of Phelps Dodge for infilling, reserve confirmation, step-out exploration and condemnation. During the 2006 drilling program, mineralization in three new areas just west of Kwatebala was discovered (Mwinansefu, Ditoma and Shinkusu). Concession exploration for 2007, which includes further resource definition drilling at these new areas, is budgeted to accomplish approximately 45,000 meters of drilling. The intent is to have significant additional proven/probable ore reserves defined by the time the initial facilities go into operation to support potential expansions in the early years of initial operations.

Southern Katanga Mining Project

Geological Setting

All of South Katanga projects are located within the Central African Copper Belt which represents one of the world’s largest known Cu-Co metallogenic provinces and contains some of the worlds richest Copper/Cobalt mines. Nearly all the economically important deposits occur as stratiform orebodies within the Mine Series of the Roan Sequence. Roan sediments were brecciated and brought to surface along several sub-parallel arcuate thrust structures during the Lufilian Orogenic period.
Uranium-Nickel-Gold-and Platinum Group metals are commonly associated with the Cu-Co mineralisation. The Shinkolobwe deposit hosted in Mines Group sediments was the world’s largest uranium producer.

The Dikulushi copper-silver deposit is a hydrothermal vein, hosted by an alternating sequence of sandstones and shales of the Mongwe Formation, which is stratigraphically above the major deposits of the Central African Copperbelt. The main vein is orientated ENE and dips to the south at about 70º. Disseminated mineralization occurs in the hanging wall of the main vein, associated with a fracture zone that parallels a major NE-trending fault, the Tambe Fault, which is believed to have been the main feeder zone for mineralizing fluids. The deposit is situated on the northeastern nose of a regional doubly plunging anticline, where this fault intersects the contact between the Mongwe Formation and an underlying carbonate unit (the Kiaka Formation); this intersection is considered to be a key control on the location of ore. Copper mineralisation is primarily massive and disseminated chalcocite (in which silver occurs in solid solution), but bornite, minor chalcopyrite and native copper also occur. Zinc and lead, as sphalerite and galena, are minor components of ore at the western end of the deposit.

Several copper occurrences have been discovered in the Dikulushi area (Kibili Mensi, Kaswete, Kasumbula), a few of which have been worked by artisanal miners.

The three deposits at Kinsevere are named, from north to south, Tshifufiamashi, Tshifufia and Kinsevere Hill. They are hosted by what appear to be two separate "mega-fragments" of prospective stratigraphy (Lower Roan Supergroup/Mines Group), which are surrounded by younger sediments of the Kundelungu Supergroup, of the Katangan System. Lithologically, the deposits occur in a mixed sequence of siliciclastic and carbonate rocks, which are typical hosts to Katangan Copperbelt mineralization.

Most of the Kinsevere Mineral Resource defined to date (in all three deposits) is oxide ore, which forms a thick (>100m) supergene blanket that overlies sulphide mineralisation. The dominant copper oxide minerals are malachite (carbonate) and pseudo-malachite (phosphate), which are disseminated throughout the host rock, or as veins and/or veinlets that sometimes coalesce into prominent "clots". Heterogenite (cobalt oxide) is sometimes inter-grown with the copper, but is always a minor component of the ore.

The dominant copper sulphide mineral of the primary ore is chalcopyrite, but minor bornite, chalcocite, and cuprite also occur, along with native copper and pyrite. Most of this mineralisation occurs in veins and veinlets that often cross-cut bedding.

All three of the deposits are interpreted to be examples of structurally modified stratiform copper mineralization, which has weathered to form a supergene blanket of oxide ore.

Geology of the Kolwezi Klippe

The copper-cobalt deposits in the Kolwezi District are located within the so-called Kolwezi Klippe, a discrete geological terrain that is interpreted to have been thrust, by several tens of kilometers, over younger rocks into its current position. The Klippe hosts numerous “fragments” of prospective “Mines Group” stratigraphy, and is reputed to contain 880Mt of ore (past production and known resources), with an average grade of 4.5% Cu and 0.4% Co - for an estimated global resource of 40Mt copper and 3.5Mt cobalt Approximately 70% of the total historical production from Katanga is reported to come from the Kolwezi Klippe, and in the late 1980s production amounted to 350,000t copper per annum.

Mineralisation in the Kolwezi Klippe typically occurs in two 10-20m thick orebodies, within specific stratigraphic horizons within the Mines Group “fragments.” Both are hosted by dolomites and dolomitic shales, but the “Lower Orebody” is separated from the “Upper Orebody” by a 20m thick barren zone of silicified, stromatilitic dolomite (the so-called “RSC” unit). Because the “RSC” is silicified, and therefore very hard, it forms characteristic outcrops, which are useful as a marker horizon for regional mapping
