Gold in Zambia

History
Gold mining in the Mumbwa region started in 1927 and continued through until 1941. Mining focused on an iron-oxide gossan at Dunrobin, which was developed initially by shallow open cut methods, and then by underground mining on a quartz vein, to a depth of 75 m below the surface.
The total production recorded from this period of operation was 32,000 oz at an average grade of approximately 10 g/t Au. Mining at Matala began in 1928, with a reported grade from initial mining of 49,5 oz of gold per tonne ore from underground operations.

• Dunrobin mine re-opened in 1997 with a planned output of 65 kg of gold by the end of that year.

• Aim Resources (LSE:AIMR.L) is exploring the Mumbwa Copper-Gold project located in south-central Zambia. AIM is earning a 70% interest in the project from BHP Billiton. Billiton explored the Mumbwa licence area during the mid to late 1990's. The Kitumba region contains a large, and in the areas tested so far, low-grade copper or copper-gold bearing, breccia system. The mineralization at Mumbwa is associated with large–scale highly variable magmatic-hydrothermal iron oxide breccia complexes that display evidence of multiple brecciation and Aim reported significant mineralization from drilling in May, 2007.
  

• Luiri Gold Ltd (Canadian) Luiri Hills Project area is adjacent to the ground held by BHP Billiton in joint venture with other parties. Prospecting has been focussed on the the Dunrobin and Matala mines and immediate surrounding areas. The new mineral resource estimate for Luiri Gold is 108,000 oz of gold in 1,62 million tonnes grading 2,1 g/t in the indicated category, and 173,000 oz of gold in 1,3 million tonnes grading 4,1 g/t in the inferred category and complies with the Australan JORC Code. On December 11, 2007, Luiri Gold announced a C$3 million private placement to support its exploration program at Luiri Hill project in Zambia, and to pursue acquisitions.
  

• Zambezi Resources Limited is exploring the gold occurrences at Chakwenga, Moiya and Kangaluwi in the Chakwenga region, southern Zambia, which resulted in 5 gold projects.
