- Singida Administrative District, Singida Region, central Tanzania
Eight prospecting licences covering approx 240 km²
Three mining licences covering 30km²
- Some of the prospecting licences and one of the mining licences are wholly owned by Shanta Mining Corporation Ltd (SMCL).
- There is a minority interest of up to 10% in two of the mining licences and some of the prospecting licences which is held by GL Josue and JB Joel Limited. Depending on the option chosen, the minority holder will have up to a 10% earn-in interest or a smaller royalty. Therefore, SMCL has at least 90% ownership of the Singida project.

Project potential and prospects
In August 2011, Shanta Gold released a feasibility study which indicated a production of c450,000 ounces over a 10 year Life of Mine. Capital cost was estimated at US $39 million for construction and pre-strip activities with a cash operating cost of US $412 per oz
Project development to date
To date the following geological and other work has been completed as follows:-
- Conventional stream sediment geochemical sampling programs
- Grab, soil, pit and trench geochemical sampling programs
- Detailed geological and structural mapping programs
- Airborne radiometric and magnetometry surveys
- Extensive Induced Polarisation surveys
- Comprehensive drilling programs have been completed on prospecting licences PL2384/2003, PL2792/2004 and various Primary Mining licence areas.
- A total of approximately 74 000 m Reverse Circulation (RC) drilling and 6 800 m Diamond Core (DC) drilling, commissioned at numerous prospects, has been completed to date.
- All drilling results have been incorporated into a JORC compliant Preliminary Resource Assessment.
- Commissioning and completion of ESIA studies.
- Commissioning and completion of gold deportment studies with very favourable results achieved.
- Commissioning of feasibility studies conducted by independent consultants.
- National Environmental Management Committee (NEMC) certification obtained.
- Applications for three 10km² mining licences submitted.
- Three 10km² mining licenses awarded to SMCL.
- Initiation of preliminary resettlement negotiations
Total in situ resources to date
A resource for the Singida, determined by independent consultants during the 2nd Quarter 2009, is summarised below:
The resource* comprises seven prospects.
- Measured Resource (1.0 g/t lower cut-off grade) = 432,293 at 4.05g/t
- Indicated Resource (1.0 g/t lower cut-off grade) = 117,694 at 1.96 g/t
- Inferred Resource (1.0 g/t lower cut-off grade) = 308,508 at 2.28 g/t
- Total Resource (1.0 g/t lower cut-off grade) = 858,485 at 2.84 g/t
The geology of the Singida area is dominated by the Tanzanian granite-gneiss craton. Poorly exposed greenstone remnants were identified within the granite gneiss terrain during mapping by the Geological Survey of Tanzania (Haidutov 1976). These greenstones comprise an intercalated sedimentary and volcanic sequence with similarities to the Nyanzian Supergroup (System) of the Lake Victoria Goldfields.
The volcanic rocks encountered are predominantly basaltic lava and localised hypabyssal diorite/microdiorite intrusives. Meta-sedimentary rocks consist mainly of metaquartzitic lithologies, with subordinate siltstones, mudstones and banded ferruginous chert also encountered. The orientation of the layering is generally parallel to the basement foliation. Isoclinal folding is also evident.
The Nyanzian lithologies are generally metamorphosed to greenschist- and lower-amphibolite facies with localised occurrences of upper amphibolite grade. Post tectonic granite intrusives are common throughout the area.
Gold mineralisation is associated with penetrative brittle-ductile, steeply dipping, quartz veined shear zones that generally approximate the strike of lithological contacts.
The area south of Singida is exceptionally flat lying with little relief except for the granite intrusives that form prominent tors. Weathered overburden profiles are dominated by Neogene transported pedogenic gravels and related soils. Black Cotton soils (Mbuga) occurs locally.
