Oklo’s deep drilling strikes gold at Seko
Link copied to
Special Report: Oklo Resources’ (ASX:OKU) Seko gold discovery is looking increasingly significant, with drilling confirming the extension of the system at depth into fresh rock at the SK1 North target.
Results from the first six deep diamond holes over a 350m strike returned gold mineralisation associated with wide zones of hydrothermal alteration.
Notable intersections are 3m at 3.55 grams per tonne (g/t) gold within a broader zone of 22m at 1.28g/t gold from 341m, 3m at 2.97g/t gold within 6m at 1.68g/t gold from 287m and 2m at 5.05g/t gold from 273m.
Adding to Oklo’s belief that Seko is potentially massive, the alteration shows strong similarities to other large gold systems in the region such as B2 Gold’s 7.1Moz Fekola mine and Barrick Gold’s 18Moz Loulo-Gounkoto complex.
“The results from our 6 first exploratory diamond holes testing SK1 North at depth are highly encouraging and importantly have confirmed a potential root zone to the extensive oxide gold mineralisation extending along the ~3km SK1 North – Koko trend,” managing director Simon Taylor said.
“The hydrothermal alteration also exhibits strong similarities to other large gold systems in the region. With the Seko gold system remaining very much open at depth, we look forward to further unlocking its potential in the ongoing 2021 drilling program.
“Drilling is now focusing on extensions to the shallow oxide gold mineralisation at SK1 South with a further 29 holes completed and awaiting further assays.”
Seko is part of the Dandoko project, within Oklo’s 505sqkm land package over the Kenieba Inlier in Mali, about 30km east of Fekola and 50km south-southeast of Loulo-Gounkoto.
Shallow reconnaissance auger drilling in 2016 and 2017 produced a 15km-long trend of gold anomalies that was followed up by drilling that resulted in the Seko discovery.
All six step-out diamond holes from the current deep drilling have intersected wide zones of hydrothermal alteration and gold mineralisation in fresh rock.
Further planned drilling will test the potential for high-grade plunging shoots at depth as seen at the nearby Fekola and Yalea gold deposits.
