A complex package of Birimian greenstones comprising sediments and volcanics hosts an Eburnean-aged northwest trending structural zone providing several favourable settings for Syama or Tengrela style structurally controlled mineralisation.
Diendo Project covers 283km2 of under-explored Birimian terrain along the southern extension of a structural trend that is host to the 600k oz Au Tiekoumala resource, and the Foulalaba mineralised zone located 5km from the project boundary. IGS’s Tanala Project sits on this same structural trend 4km north of Tiekoumala
The Company began acquiring ground at Diendo in April 2011. The surface geochemical sampling program initiated mid-2011 at Diendo has generated significant gold anomalies. The project expanded to 5 licences totalling over 283km2, with 5,647 surface samples collected, principally from termitaria. The principal gold anomaly extends 15km northwestward and is focussed at Diendo Sud Permit in the southeast. A second, northeast-trending, surface gold anomaly lies to the west.
IGS used auger drilling to refine targeting in surface gold geochemical anomalies. Subsurface gold anomalies produced by results from the 819 auger samples are coincident with the main termitaria gold anomalies. Limited Air Core and RC drilling in the Diendo Sud permit tested the southern 5km of the 15km gold anomaly, and produced mineralised intersections to 2m of 0.5 g/t Au. A significant extent of this main anomaly has yet to be tested, notably where it intersects the second, northeast-trending termitaria anomaly.
