Copper

  1. Goldcrest Resources Ltd (Canadian, GCL.V} is exploring the Gaoua copper-gold project in Burkina Faso. The drilling of the Gaoua Cu-Au prospect is being executed under an option agreement that the company signed with Phelps Dodge Exploration Corporation, a wholly-owned subsidiary of Freeport McMoRan Copper & Gold Inc. Most of the breccia-hosted mineralization consists of hypogene chalcopyrite with which gold values appear to be closely correlated.

Geology

Birimian-age greenstone belts cover large parts of Burkina Faso and host the known structurally controlled mineralization.
  1. Orezone Resources (Canadian, TSX:OZN.TO; Amex:OZN, and also active in Niger) is exploring a number of properties including Essakane, where Gold Fields (NYSE:GFI; JSE:GFIELDS) is the operator, earning 60%. The Essakane deposit hosts an 1,9 million oz indicated resource at 1,60 g/t Au and 1,5 million oz of inferred resource at 1,70 g/t Au (0,50 g/t Au cut-off). Further drilling by Gold Fields increased the indicated resource to 2,6 million oz at a cut-off of 1 g/t or an indicated resource of 3,3 million oz and inferred 800,000 oz of gold at a cut-off of 0,5 g/t (April, 2007). The pre-feasibility study showed that an open cast mine and a 5,4 million tonne/year carbon-in-leach plant were viable and could produce 300,000 oz of gold a year.
    Intiédougou (Golden Hill) has an inferred resource of 157 000 oz gold at 1,4 g/t Au.     The Bondi deposit has an indicated resource of 162 964 oz at 2,88 g/t Au. The Sega deposit has an inferred resource of 300 000 oz at 2,8 g/t Au. The Bombore deposit has a resource of 1,1 million oz gold at an average grade of 1,5 g/t Au. Licences also cover known gold occurrences at Tomena and Seguenega.
  2. Goldbelt Resources Ltd (Canadian, GLDRF.PK, GLD.V) is exploring the Inata deposits, an estimated resource of 15,65 million tonnes grading an average of 1,9 g/t Au (948,000 oz gold) in the measured and indicated categories and 4,06 million tonnes grading 1,4 g/t gold (190,000 oz Au) in the inferred category, as well as known occurrences at Belahouro, Houndé, Bougouriba. (The Bougouriba belt, south of Houndé, is currently host to 20,000 artisanal miners) and at Quedrogo, Koupela region.
  3. Semafo Inc's (Canadian, TSX:SMF.TO; SEMFF.PK, and operating the Kineiro mine in Guinea and Samira Hill mine in Niger) Mana project with the Nyafé and Wona deposits totalling 9,443,000 tonnes of ore at an average grade of 2,89 g/t Au.
  4. Goldcrest Resources Ltd (Canadian, GCL.V} is exploring the Gaoua copper-gold and Kampti and Titao Sud gold projects in Burkina Faso. The drilling of the Gaoua Cu-Au prospect is being executed under an option agreement that the company signed with Phelps Dodge Exploration Corporation, a wholly-owned subsidiary of Freeport McMoRan Copper & Gold Inc. Most of the breccia-hosted mineralization consists of hypogene chalcopyrite with which gold values appear to be closely correlated.
  5. AXMIN Inc (Canadian, TSXv:AXM, and also active in the Central African Republic, Mali, Sierra Leone and Senegal) sold its interest in the Bouroum project to High River Gold Mines.
  6. High River Gold Mines Ltd (Canadian, TSX:HRG.TO) has an indicated 8,6 million tonnes at a grade of 3,0 g/t Au or 827 000 oz gold at the Taparko-Bouroum project.
  7. Jilbey Gold Exploration Ltd (now merged with High River Gold) has drilled out a measured and indicated 1,373 million tonnes grading 3,33 g/t or 147 250 oz gold at Bissa Hill.
  8. St Jude Resources Ltd (Canadian) is drilling a deposit at Goulagou.
  9. Sanu Resources Ltd (Canadian, SNU.V, also active in Eritrea and Morocco) has four exploration licences (Moule, Nyieme, Loto, and Kodyel) totaling 827 km².
