The Pramkese concession is located approximately 10km South-East of the District Capital of Kade in the Eastern Region of Ghana. The concession is approximately 10km to the East of the town of Akwatia, a hub of alluvial Diamond mining activity. The area is located on Geological Survey Field Sheet 93, topographic sheet No 601c3, and lies between longitudes 0º45'W and 0º49'W and latitudes 6º04'N and 6º14'N, within the Kwaebibirim District Assembly, immediately east of the Birim River and covers an approximate area of 65.8km2.
|1990 to 1994||Basogad Ltd. undertook extensive test pitting and gridding over 250 hectares for ~5Mm3 at 0.86 cts/m3 and 0.28g Au/m3 (~4.3M carats / 45,000oz Au).|
|2003 to 2011||Paramount/Leo Shield JV. Conceptual exploration target of ~10M carats and 80,000oz Au. Ten test pits/samples (60-160 litres) with seven of these containing one or more Diamonds (max was 3) with very fine Gold noted in all samples.|
|2011 to 2012||Leo Shield. Six test pits with Gold grades slightly lower than Basogad, with Gold grains <100μm (and Diamonds <1mm). In October 2012 over 150 Galamsey miners were estimated on site.|
The Story So Far.
Significant Diamond occurrences were encountered through the Pramkese concessions.
Over the Birim concessions area lithological units are dominated by intercalated sequences of Birimian Volcanic and meta-sedimentary units, which have been intruded by significant occurrences of basin type granitoids. All units have undergone sustained weathering, degradation and oxidation. Locally it is the ultramafic or ultrabasic units that are believed to be the source of the majority of the alluvial diamonds found in the immediate district.
Over the Pramkese area the local geological domain is dominated by intercalated sequences of Birimian Volcanic and meta-sedimentary units, which have to a lesser extent intruded by minor occurrences of basin type granitoids and ultrabasic lithologies.
