Exploration

Kolwezi (DRC)

The famous Kolwezi Klippe is one of the most productive regions of the African Copperbelt. Joint venture holdings of Anvil (80%) and Gécamines (20%) cover 29% of the Klippe which has traditionally produced more than 70% of the DRC copper mineral product. The area has extensive un-mined deposits with potential for the revival of a major industry.
Anvil has four key areas of interest:

• Mutoshi, previously the site of one of the world’s most productive copper mines
• Kulu, where the Company has a tailing processing operation
• Nioka-Kampese, and
• Kamukonko

The current priority target for Anvil’s exploration group is to identify 500,000 tonnes of open-pittable copper resource at Mutoshi to justify an SX-EW copper plant.

In addition, the Kolwezi program is looking to define additional resources for the Kulu project to support the development of a major processing plant.

Tenements

Anvil’s tenement portfolio in the Kolwezi District is comprised of four Mineral Licenses. Two of the three Mining Licenses (Permis d’Exploitation), PE2604 (Mutoshi) and PE2605 (Nioka-Kampese) are located within the Kolwezi Klippe (shown in the following map), while the third, PE663 (Kamukonko) covers a small unit of prospective stratigraphy off the main Klippe. The three PE’s have a combined area of 80.7km². The fourth licence is a Tailings Processing Licence (Permis d’Exploitation Remblais), PER2812 (Kulumaziba or Kulu), which covers an area of 57.8km², over the 14km of the Kulumaziba River. All of the tenements are held by Société Minière de Kolwezi (SMK), a joint venture company between Anvil (80%) and Gécamines (20%).

Anvil tenements cover 29% of the Kolwezi Klippe.

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.

Current Work Program

Discovery of an open-pittable copper oxide resource, to justify commencement of a Feasibility Study for an SX-EW plant:

• Infill drilling at Nioka
• Infill drilling at Mutoshi N.
• Completing scope drilling of Nioka fold "limbs".
• Scope drilling of other areas of interest at Mutoshi.

Definition of additional resources for the Kulu HMS plant:

• Drill testing of possible breche deposits, immediately west of the Mutoshi Open Pit.
• Testing the grade of breche ore stockpiles.
