The London-based company is targeting an ironstone formation, along which an almost continuous stream of artisanal workings occurs over 3.5 km of strike length. Holes were drilled to test for downdip extensions beneath those workings, which, in places, reach 30 metres in depth.
Gold values varied from 0.36 to 7.15 grams per tonne over true widths of 1.1-12 metres. The interval-weighted averages were calculated using a cutoff grade of 0.3 gram, a cutting factor of 10 grams, and a minimum drill width of 2 metres.
Results include: 2 metres (59-61 metres) of 7.15 grams in hole 3; 21 metres (109-130 metres) of 2.97 grams in hole 11; 3 metres (108-111 metres) of 3.7 grams in hole 16; and 4 metres (25-29 metres) of 0.36 gram in hole 17.
Most of the holes intersected two or more mineralized intervals, indicating that mineralization occurs in multiple zones (which have since been determined to be parallel). Holes were collared 100 metres apart, covering 2.8 km of strike length, and drilled to a vertical depth of 100 metres.
Mineralization is associated with both the ironstones and phylittic country rocks. Follow-up drilling will consist of 6,000 metres to test the remaining 700 metres of known mineralized strike length (ironstones have been mapped along a strike length of 6.5 km). An area known as Adit 22, which is situated some 1.5 km from the nearest historical working, will also be tested. Previous exploration returned an average of 2.06 grams in channel samples taken over 18 metres and 3.26 grams in chip samples taken over 5.8 metres.
Collision is one of several gold and diamond properties held by Consolidated African; several of these are at the drill-ready stage.
