The South African-based consultancy firm Resource Exploration & Development (RED) has recommended follow-up ground work on all properties held by Serengeti Diamonds (SGD-V) in Tanzania.
Serengeti owns an 80% interest in a large portfolio of diamond properties in the country. These comprise mining blocks adjacent to known diamondiferous kimberlites which are being worked by artisanal miners. It holds seven reconnaissance licences covering 87,000 sq. km. The remaining 20% is held by locally based Tanzania Diamond Mines (TDM).
RED has recommended pitting on the Kahama lease, with sidewall sampling of diamondiferous horizons for concentration and labratory analysis.
Earlier bulk testing by TDM indicates that the Kahama group of mining blocks has a potential resource of some 400,000 carats. A 300-tonne gravel sample recovered 306 carats, including one stone of 3.65 carats and 138 stones larger than 1 carat. A 50-tonne-per-hour pan washing plant is now installed.
On the southern block, where previous owners carried out extensive pitting, RED recommends additional pitting on a closely spaced grid to confirm estimates, as well as bulk sampling.
To test the quality of horizons on the northern block, RED recommends pitting or reverse-circulation drilling. The firm resampled old pits and completed a microprobe analysis of garnets and ilmenites on the Dodoma licence.
