Geology
The regional trend of the Manica greenstone belt, on the Zimbabwean border, which hosts the known gold mineralization and only operating mine in the past, is east west. It consists of intensely metamorphosed and strongly foliated volcanic rocks, with subordinate banded ironstone, tuff and greywacke. The surrounding rocks are granite or gneiss from the Archaean basement. Structurally, the greenstone belt is complex with at least four major deformation phases identified.There are three east-west striking major shear zones which control the gold mineralization.

- Alluvial deposits within the Revue, Inhamurra, Muza and Chimezi rivers. An estimated resource potential of these alluvial deposits amounts to 112 million m3 at an average grade of 0.25g/m3, yielding approximately 25 t of gold.
- The Niassa province in the northwest of Mozambique has seen an increase in gold exploration and mining, in particular by artisanal workers. Gold is located within structurally controlled quartz veins located within Proterozoic greenstone belts located close to the shores of Lake Nyasa. Currently all gold production in this region comes from artisanal alluvial workings that grade at between 0.5 – 3 g/m3. It is estimated that about 12 t of gold has been produced from this region since 1990.
- Pan African Resources plc (AIM:PAF) is developing the Manica project where an orebody with an estimated 12, 5 million t at a grade of 2,58 g/t Au or 1,038 million oz of gold, has been outlined.

- Natural gas proved reserves: 127.4 billion cu m (1 January 2005 est.)
Tantalum
Mozambique’s total tantalite production was 281,212 kg or 619,000 lb in 2005 compared with 712,095 kg (1,57 million lb) in 2004, according to the US Geological Survey.- Noventa is operating the Marropino opencast tantalum mine expected to reach its capacity of 300,000 lb/year in the second quarter of 2007. Noventa currently has ore reserves of 11,4 million tonnes. The company has 12 licences in Mozambique and is exploring deposits at Morrua and Mutala; the latter having been mined on a small scale for 30 years. Reserves and resources of tantalite amount to 19 million pounds.
Uranium
- OmegaCorp Ltd is exploring the Mavuzi Project, located roughly 40 km northwest of the provincial centre of Tete in northwestern Mozambique and comprising four granted licences covering approximately 700 km2. The central licence covers the historical Mavuzi Uranium Mine. It is also exploring the The Zambezi Valley Project, approximately 300 km due west of Tete in northwestern Mozambique. The single licence covers over 600 km2 and lies on the border with Zimbabwe.
