    Oklo Resources hits up to 32m @ 10.57 g/t Au, extends SK1 North to 500m strike

    Oklo Resources Limited (ASX: OKU) has announced a highly encouraging update from the ongoing resource definition drilling program at its Dandoko Project in west Mali, Africa.

    The company reported that assay results were received from a further 28 RC holes and one DD hole from the SK1 North discovery at Seko.

    OKU said that further wide zones of high-grade gold mineralisation were returned from step-out drilling along strike and at depth.

    Significant intersections include 38m at 5.65g/t gold from 159m including 10m at 19.22g/t gold from 165m including 6m at 30.94g/t gold from 168m, and 1m at 102.37g/t gold from 172m; 32m at 10.57g/t gold from 52m including 10m at 30.96g/t gold from 58m; 26m at 7.54g/t gold from 70m including 8m at 14.44g/t gold from 84m; 20m at 3.32g/t gold from 100m including 5m at 8.64g/t gold from 112m; and 8m at 9.25g/t gold from 22m including 2m at 31.85g/t gold from 24m.

    The company reported that SK1 North was successfully extended to 500m in strike length and to a vertical depth of up to 145m with returning individual grades of up to 102.37g/t gold (equivalent to ~3.3oz/t gold) over 1m.

    OKU announced that the expanded RC and DD drilling program is ongoing both down dip and along strike to the north to accelerate the evaluation of this discovery for incorporation into Oklo’s maiden Mineral Resource estimate (MRE) scheduled for completion in Q2 2020.

    The company reported that the AC drilling south of Seko towards the Koko discovery is now complete with assay results pending.

    Dandoko project

    The Dandoko Project covers 134km2 within the Kenieba Inlier of West Mali in West Africa. It is located in close proximity to numerous world-class gold deposits including B2Gold’s 7.21Moz Fekola gold project 30km to the west and Randgold’s 12.5Moz Loulo Gold Mine 50km to the north-northwest.

    The Company currently holds ~500km2 of highly prospective ground in this emerging world-class gold region. Extensive gold anomalies have previously been outlined by auger drilling along the 12km-long Dandoko gold corridor.

    Significant prospects of the Dandoko project include Seko, Sory, Dabia, Gombaly, Diabarou, Disse, Selingouma North, Selingouma South, and Bembala.

    Seko prospect: The Seko prospect comprises of five mineralised gold trends (Seko Anomalies) SK1, SK2, SK3, SK4, and SK5, with a combined strike length of ~7km, with significant gold potential.

    Field program at Seko

    The company’s current field program at Seko is focused on infill drilling and closing off previously defined zones of gold mineralisation at Seko and adjoining areas in advance of its maiden MRE.

    OKU reported that all assay results have now been received and reported from the initial phases of aircore (AC), reverse circulation (RC) and diamond core (DD) resource definition drilling at SK1, SK2 and SK3 to depths averaging 85m and up to 184m.

    The company said that evaluation of the emerging SK1 North discovery, located at the northern end of SK1, is ongoing. OKU has now announced the latest round of results from SK1 North.

    Previous drilling at SK1 North

    The initial phase of drilling at SK1 North had returned a spectacular intersection of 47m at 10.95g/t gold from 48m, following which Oklo’s Board approved additional RC drilling to test this emerging zone of high-grade gold mineralisation. The follow-up drilling had then returned further exceptional intersections including 55m at 7.65g/t gold from 54m, 51m at 4.28g/t gold from 63m, 31m at 7.12g/t gold from 30m and 29m at 2.46g/t gold from 51m.

    A series of step-out DD holes testing the down-dip continuity of the high-grade gold mineralisation had then successfully intersected 30m at 8.54g/t gold from 135m in the deepest hole and 34m at 4.07g/t gold from 83m along strike.

    Further high-grade results from SK1 North

    The company announced that assay results have been received from a further 28 RC holes and one DD hole at SK1 North.

    DD hole RDSK20-062

    The company announced that diamond drill hole RDSK20-062 has confirmed high-grade mineralisation extending to at least 200m down dip (~145m vertically), returning 38m at 5.65g/t gold from 159m downhole, including, 6m at 30.94g/t gold that in turn included 1m at 102.37g/t gold (equivalent to ~3.3oz/t gold).

    RC holes

    Oklo Resources reported that the five RC holes drilled along Section D, located ~100m north of Section A, intersected further significant widths of gold mineralisation.

    Significant intersections include 32m at 10.57g/t gold from 52m (including 10m at 30.96g/t gold) in hole RCSK20-206, 26m at 7.54g/t gold from 70m (including 8m at 14.44g/t gold) in hole RCSK20-207 and 20m at 3.32g/t gold from 100m (including 5m at 8.64g/t gold) in hole RCSK20-210.

    Other significant intersections to the north of Section A included 24m at 1.21g/t gold from surface (including 2m at 5.27g/t gold) in hole RCSK20-216 and 10m at 1.15g/t gold from 14m and 3m at 6.28g/t gold from 90m in hole RCSK20-215.

    The company said that the RC holes completed to the south of Section A returned the following significant intersections: 8m at 9.25g/t gold from 22m (including 2m at 31.85g/t gold) in hole RCSK20-199, 4m at 3.08g/t gold from 9m in hole RCSK20-202 and 11m at 2.12g/t gold from 73m in hole RCSK20-201.

    Strike extended

    The company reported that the drilling completed to date has confirmed the SK1 North mineralisation over a length of 500m, which strikes north to northeast and dips moderately to the east from surface. The zone remains open, with drilling ongoing down dip and along strike to the north.

    OKU said that the drill coverage over the northernmost extent of the zone is currently being extended to investigate an interpreted change in strike towards the north.

    Updates and further work

    The company reported that AC, RC, and diamond drilling is ongoing on the Company’s SK1 North prospect with a view to completing a resource estimate for the Seko prospect in Q2, 2020.

    Oklo Resources reported that the drilling is continuing at SK1 North with a steady flow of results expected in the coming weeks. The company said that assay results are also pending from approximately 9,500m of reconnaissance AC drilling between Koko and SK1, with the samples from SK1 North currently being given priority.

    OKU said that two more step-out DD holes have since been drilled on Section A. Hole RDSK20-066 was completed to a downhole depth of 256m with all assay results pending. The hole intersected similar gossanous and altered sediments to hole RDSK20-062 at depths of 217m and 228m. The second deeper DD hole is currently in progress to a planned downhole depth of 280m.

    Management comments

    Oklo’s Managing Director, Simon Taylor said: “With SK1 North emerging as game-changer for Oklo, all efforts are currently being made to fast track its evaluation prior to finalising our maiden MRE. The step-out drilling has now confirmed the strike length over 500m, with the deeper diamond drilling continuing to extend the zone at depth.

    We are particularly delighted with the exceptional results returned from Section D in the north, including 32m at 10.57g/t gold and 26m at 7.54g/t gold, with several of these holes ending in mineralisation.

    The northernmost traverse indicates that the zone is swinging towards the north and drill coverage is currently being extended over this area. We look forward to providing further updates on our progress at SK1 North in the weeks ahead, which so far remains unaffected by the COVID-19 pandemic.”
