Diamond drilling on the Samira gold project in Niger has enabled Etruscan Enterprises (TSE) to trace the Samira sedimentary horizon over a strike length of 2.7 km.
Geophysical surveys indicate that the horizon (along which intervals of up to 80 metres of 3.43 grams gold per tonne have been found) continues to the north under a laterite plateau, and to the east under sand cover. It is open in both directions.
A second geophysical trend, called the Southern horizon, exists 400 metres south of the Samira deposit. It has been tested by two holes. A 100-metre-thick sequence of sedimentary rocks similar to those of the Samira horizon was intersected, but assaying is not yet complete.
Geophysical surveys have identified a strong induced-polarization anomaly on the Boulong Djonga grid, 7 km northwest of Samira.
The anomaly, which has been traced for 600 metres and is open along strike in both directions, lies beneath gold fields being exploited by local, small-scale miners. Geochemical anomalies have also been identified along the structure.
Etruscan has started an 8,000-metre program of reverse-circulation drilling at Samira in order to expand saprolitic reserves.
The latest diamond drill results from the Samira are shown at left.
