Kopane's principal focus is the development of the Main Pipe project, in Liqhobong, Lesotho. This kimberlite pipe has a surface area of 8.6 hectares, with the potential to produce at a rate of over one million carats per annum for 20 years. Kopane owns a 75% interest in Liqhobong Mining Development Company ("LMDC") the local operator and license holder. The remaining 25% is owned by the Government of Lesotho ("GoL"). Production at the Satellite Plant was suspended on 1 December 2008 due to a decline in rough diamond prices. Prior to suspension the Liqhobong Plant was running at a rate of 420,000 tonnes/year while treating weathered Main Pipe kimberlite.

Kopane has completed a Pre-Feasibility Study (PFS) which demonstrated the economic viability of the pipe to an appropriate level of accuracy and is now well advanced on the DFS. On 17 November 2008, Kopane issued an Interim Resource Statement which showed a major increase in Main Pipe size, grade and value from previous studies. The salient features from this work were:

  • Total resource tonnage of 76 million tonnes, up 79 % on the Pre-Feasibility Study ("PFS") statement published last year of 42 million tonnes.
  • Increase in the average grade to 39.1 carats per hundred tonnes ("cpht") (PFS - 27.8 cpht).
  • Increase of 156 % in the gross diamond resource of 29.6 million carats (PFS - 11.5 million carats).
  • Increase in the average run of mine carat value to $86 (PFS - $70).
  • Increase in the indicative value of the Main Pipe by 213% to $2.5 billion.
  • Completion of a 25 hole Large Diameter Drilling ("LDD") programme.

INDICATED RESOURCE INCREASES BY 141 % TO 38.6Mt (10th September 2009)

Improvement in grade confidence, based on 141% increase in indicated resource to 38.6 million tonnes, potentially increases the depth of a future open pit to 180 metres.

Main Pipe total resource of 90.03 million tonnes, an increase of 19.1% over the interim resource statement issued in November 2008.

Gross diamond resource of 29.7 million carats (Kopane attributable 22.3 million) contained in the Main Pipe to an average depth of 510 metres, with an estimated in situ value of $2.6 billion based on September 2008 bulk sample diamond values.

The estimated Main Pipe value of $2.6 billion could be increased significantly following further work to clarify grade and from the impact of bonanza stones

Large diameter reverse circulation drilling results support an average grade of 33 cpht to at least 510 metres average depth.

$86 per carat run of mine valuation does not include the positive impact of large and bonanza stones
