On March 10, 2023, the High Court of Namibia has rendered its judgment and reviewed and set aside the decision of the Minister not to renew the Haib Copper license EPL 3140. As per the court verdict, the Ministry has re-opened the application renewal procedure for the Haib Copper license. |

Summary:
Deposit Types
The Haib copper deposit is a porphyry copper deposit of palaeo-Proterozoic age. Porphyry copper deposits are a major world source of copper (also molybdenum, silver and gold) with the best-known examples being concentrated around the Pacific Rim, in North America, South America, and areas such as the Philippines. Most of these deposits are relatively young, of Tertiary or Cretaceous age.
The Haib deposit has all of the above defined geological characteristics and is therefore a porphyry copper deposit, being formed within intrusive Proterozoic rocks at 1 880my BP.
Mineralization
The Haib deposit is in essence a very large volume of rock containing copper mineralization. The grade is variable from higher grade in the three core zones (possibly averaging >0.4%) progressively decreasing towards the margin of the deposit. The area in which mineralization has been identified equates approximately to the outer ring of the GFM 22-year pit design. This gives a pit size of 2200x1250x400 metres equating to some 1300 million tonnes of mineralized rock. The deposit is still partially open to the west (at surface) and to the south at depth.
Mineralization is not confined to any specific units although the quartz feldspar porphyry tends to contain the three higher grade zones. Mineralization is clearly secondary and post-dates the formation of the original volcanic pile. Mineralization is widespread throughout although frequently ass ........
Summary:
The characteristics and geometry of the Haib deposit as well as its proximity to surface mean that the deposit lends itself to extraction by open pit mining methods. The deposit is basically composed of hard rock material and the mining operations will involve drill and blast of all excavated material, which will be designated as either mineralized material or waste on the basis of samples taken from blast hole drilling and application of the cut-off grade.
Initial analysis involved mining approximately 20 Mtpa of mineralized material for a period of 20 years. In achieving this, some 405 Mt of mineralized material is mined along with some 570 Mt of waste over the 20-year life-of-mine.
Open Pit Work Roster
It is suggested that the mining operations would work 365 days in a year, less unscheduled delays such as high rainfall events which may cause mining operations to be temporarily suspended.
Bench Design
Both mineralised material and waste could be drilled and blasted on standard 5 m benches for primary crusher feed and possibly 10 m benches for waste, and then mined by hydraulic excavators; nominally ranging from two 3 m high faces to three 4m high faces, taking into account blast induced swell, into rear dump off highway haul trucks. The number of flitches to mine a bench will be dependent on the selectivity required and the size of the excavator used.
Drill and Blast
Rock fragmentation will be undertaken by drilli ........
