    Oklo unearths high-grade gold of upto 30m @ 8.54 g/t at Seko

    Oklo Resources Limited (ASX: OKU) has announced a highly encouraging update on the expanded drilling program at its flagship Dandoko Project in west Mali, Africa.

    The company reported that assay results were received from two step-out diamond holes from the expanded drilling program over the northern portion of the SK1 anomaly at Seko. OKU said that down dip continuity of the high-grade gold mineralisation was confirmed in both holes.

    Significant intersections include 30m at 8.54g/t gold from 135m including 7m at 30.69g/t gold from 142m; and 13m at 15.80g/t gold from 91m including 4m at 46.65g/t gold from 92m.

    OKU reported that gold mineralisation is now confirmed down dip to 170m (vertical depth of ~130m) and remainsopen at depth, with individual grades of up to 106g/t gold (equivalent to ~3.4oz/t gold).

    The company said that it is expecting a steady flow of news from the expanded program over the northern part of SK1 (25 holes for2,414m) and deeper RC and DD resource drilling at SK2 and SK3 (18 holes for 3,365m) over coming weeks.

    Oklo Resources reported that all new Seko results are anticipated to be incorporated into the maiden Mineral Resource estimate scheduled for completion in Q2 2020.

    The company announced that the reconnaissance AC drilling is underway between Seko and the recently discovered Kokoprospect to the immediate south.

    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.

    Drilling at Seko

    The company had commenced an ~10,000m resource definition drilling program at Seko, comprising infill aircore (AC), reverse circulation (RC) and diamond core (DD) drilling in advance of the maiden Mineral Resource estimate scheduled for completion early in Q2 2020.

    OKU said that all assay results have now been reported from the initial phase of shallow AC and RC resource definition drilling at Seko (57 holes for 5,045m), testing the gold mineralisation to depths averaging 85m and up to 184m.

    The company said that a deeper RC and DD drilling phase has recently been completed (18 holes for 3,365m) with all assay results pending. OKU said that a further 38 holes for 3,804m have since been completed over this zone.

    11 RC holes reported

    The Company had recently announced assay results from the first 11 RC and two DD holes of the follow-up program covering the northern portion of SK1 anomaly. These results had confirmed the presence of a wide zone of gold mineralisation extending over a strike length of ~250m, which remains open to the northeast and at depth.

    Significant intersections reported included 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.

    High-grade results from 2 DD holes

    The company reported that assay results were received from two step-out DD holes testing the down-dip continuity of this emerging zone of high-grade gold mineralisation.

    Both DD holes, RDSK20-057 and RDSK20-060, were drilled at -55° towards the northwest on section line A-A’.

    The company reported that the two step-out DD holes were successful in outlining depth extensions to the wide, northeast-striking zone gold mineralisation, which dips ~60° towards the southeast.

    Significant hits include 30m at 8.54g/t gold from 135m including 7m at 30.69g/t gold from 142m (hole RDSK20-060), and 13m at 15.80g/t gold from 91m including 4m at 46.65g/t gold from 92m (hole RDSK20-057)

    OKU noted that the deepest hole (RDSK20-060) confirmed the gold mineralisation extending to at least 170m down dip (~130m vertically) and remains open at depth.

    The company reported that the gold mineralisation is associated with gossanous (after sulphides) and locally brecciated altered sediments with up to 10-20% sulphides in transitional material.

    OKU said that individual samples returned up to 106g/t gold (equivalent to ~3.4oz/t gold) corresponding to the gossanous zones.

    Expanded drilling program

    The company reported that an expanded drilling program of ~3,000m was completed over the northern portion of SK1 at Seko within the Dandoko Project.

    This was approved by the OKU board after the initial phase of drilling returned an excellent intersection of 47m at 10.95g/t gold from 48m at the northern end of SK1 anomaly. This expanded drilling program is additional to the ~10,000m resource definition drilling program.

    Other results expected

    The company reported that further assay results are expected in the coming weeks from the deeper RC and DD resource definition drilling program at SK2 and SK3 (18 holes for 3,365m) and the expanded drilling program over the northern extension of SK1 (23 holes for 2,071m).

    OKU said that AC drilling is underway over the untested zone between SK1 and Koko, located ~2km to the south. Planning is also underway for additional drilling both at depth and along strike over the northern extension of SK1 following these highly encouraging initial results.

    What’s next?

    OKU said that the AC, RC, and diamond drilling would continue and follow up these and other ongoing results on the Dandoko project is scheduled to continue through January and February 2020.

    Management comments

    Oklo’s Managing Director, Simon Taylor said: “These extremely impressive results from the two step-out DD holes in the north of SK1 continue to grow the size of this emerging zone of high-grade gold mineralisation. Our focus is now on the next batches of assay results from the step-out holes drilled immediately along strike to the northeast and southwest.

    We also look forward to reporting on our progress with the deeper RC and DD resource drilling program at Seko along with the reconnaissance AC drilling to the south of SK1 towards the Koko discovery.”
