The North Mara gold deposits are situated in the Mara Musoma greenstone belt. There are several types of gold mineralisation including shear-zone-related quartz vein and disseminated gold.
Life and reserves
During 2013 we made several changes to the life of mine plan to reduce the strip ratio, volume of material to be moved and ultimate footprint of the asset. In addition, we are reviewing the option of mining a proportion of the reserve base through an underground operation, which will drive future cash flow generation and alleviate social pressures and land access experienced at the mine. Life of mine is estimated to be 10 years based on proven and probable gold reserves of 2.2 million ounces.
The North Mara gold mine is located in northeast Tanzania in the Tarime district of the Mara region. It is around 100 km east of Lake Victoria and 20 km south of the Kenyan border.
The North Mara process plant has the capacity to process an average of 8,000 tonnes of ore per day, (or c. 2.8 million tonnes per year) and produces both doré.
The site is served by the national road system and there is an airstrip 7 km from the processing plant.
The annual average temperature ranges from 16° – 29°C. Average annual rainfall for the region is 1,300mm.
North Mara is a high grade open pit mine consisting of three open pit deposits: Nyabirama, Gokona and Nyabigena.
