The first results have been received from a $5 million, phase II, 50,000-metre program over a range of targets at Seko.
Intersections of up to 24 metres at 3.67 g/t gold from 58 metres, including 9 metres at 5.95 g/t, have been returned from the first seven reverse circulation (RC) and nine diamond drill holes.
These holes were testing for extensions to the broad zone of oxide gold mineralisation at Seko SK3 anomaly.
Managing director Simon Taylor said: “The first results from the 2018 phase II drilling program further confirms our belief that the Seko discovery has the potential to host a significant gold resource.
“We are aiming to complete 50,000 metres of drilling prior to the wet season in July over a range of targets at Seko.
“This will test for lateral continuity to the shallow oxide mineralisation and depth extensions to the primary gold mineralisation.”
Other high-grade results include:
Wide zones of mineralisation
There were also very wide zones of lower grade mineralisation intersected, highlighted by 114 metres at 0.79 g/t from 90 metres that included 24 metres at 1.35 g/t and 12 metres at 2.18 g/t.
Location of the Seko trends within the 12-kilometre long Dandoko gold corridor.
Results confirm a continuous, westerly-dipping, gold-mineralised zone at SK3 extending from surface to a vertical depth of 175 metres.
Zone remains open
The zone remains open at depth and along strike with previous shallow aircore results extending the strike length to 600 metres.
Ongoing structural logging of drill core continues to assist Oklo in targeting extensions to the high-grade gold mineralisation.
A total of 68 aircore holes for 6,722 metres, 33 RC holes for 5,799 metres and 21 diamond holes for 5,062 metres have been completed in the phase II program.
Further assays pending
Assay results from a further 68 aircore, 26 RC and 12 diamond holes are pending.
As well as SK3, the program is testing the SK2 anomaly as well as other regional targets along the Dandoko gold corridor and within the Kouroufing project.
Taylor added: “The current program will provide a steady flow of news in the months ahead.”
The region hosts a number of multi-million-ounce deposits.
Oklo’s Dandoko project and adjoining Moussala, Kouroufing and Kandiole projects are within the Kenieba Inlier of western Mali.
