Oklo Resources Limited (ASX: OKU) has announced another encouraging update from the 10,000m drilling program currently in progress at Seko within its flagship Dandoko Project in Mali, West Africa.
The company reported that further outstanding results were received from Oklo’s resource definition drilling program at Seko.
OKU said that the assay results received from infill drilling at SK2 confirm the presence of a thick, coherent zone of high-grade gold mineralisation.
Significant intersections include 65m at 7.11g/t gold from 4m including 9m at 16.76g/t gold from 13m, and 16m at 12.45g/t gold from 29m, including 4m at 28.07g/t gold from 40m; and 53m at 4.34g/t gold from 95m.
Oklo resources reported that the first results received from follow-up drilling at SK2 North returned individual assays of up to 8.08g/t gold within lower grade zones of gold mineralisation associated with altered breccia.
Significant intersections include 6m at 2.86g/t gold from 124m including 3m at 4.90g/t gold from 126m; and 7m at 1.23g/t gold from 50m.
OKU reported that the assay results are pending from a further 36 holes with a deeper RC and DD program currently underway in advance of a maiden Mineral Resource estimate scheduled for completion in Q2 2020.
Oklo said that an additional 27 holes, comprising 26 RC holes and 1DD hole, are planned, with the DD hole now underway.
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
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
Oklo had approved an initial 10,000m drilling program comprising aircore (AC), reverse circulation (RC) and diamond core (DD) drilling at Seko prospect in advance of a maiden Mineral Resource estimate scheduled for completion early in Q2 2020.
Oklo’s current field program is focusing on infill drilling and closing off areas of near surface mineralisation at Seko anomalies 1-5 and surrounding areas in advance of a maiden Mineral Resource estimate.
Initial phase drilling completed
The company reported that the initial phase of AC and RC drilling is now complete (53 holes for 4,541m) testing the gold mineralisation to depths averaging 85m and up to 182m. OKU said that a second rig recently arrived on site and has commenced the deeper RC and DD drilling phase.
Assays received from further 12 holes
The company announced that assay results were received from a further 12 RC holes, comprising seven infill holes at SK2 and five follow-up holes testing the new zone of mineralisation located some 300m north of SK2.
High-grade intersections from SK2
The company announced that exceptional assay results were received from the seven RC holes at SK2. OKU said that this included the second-best intersection ever recorded by the Company, in hole RCSK19-096.
OKU said that collectively, these new results have also confirmed the presence of a thick, coherent zone of high-grade gold mineralisation at SK2.
Hole RCSK19-096
Oklo said that the hole RCSK19-096 intersected two wide zones of high-grade gold mineralisation. The first zone returned 65m at 7.11g/t gold from 4m, including 3m at 10.58g/t gold from 4m, 9m at 16.76g/t gold from 13m and 16m at 12.45g/t gold from 29m, including 4m at 28.07g/t gold from 40m. The second zone of mineralisation returned 53m at 4.34g/t gold from 95m, including 15m at 7.20g/t gold from 108m and 8m at 6.62g/t gold from 139m.
Hole RCSK19-097
OKU reported that the hole RCSK19-097 intersected 56m at 2.28g/t gold from 24m, including 3m at 6.17g/t gold from 73m.
Hole RCSK19-095
The company reported that the hole RCSK19-095 tested an interpreted east-northeast striking mineralised structure evident from previous drilling and was successful in intersecting a shallow, high-grade zone that returned 8m at 10.56g/t gold from 2m, including 2m at 16.95g/t gold from 3m.
Encouraging results from SK2 North
The company announced that the five RC holes that tested the new zone of shallow gold mineralisation at SK2 North, located 300m north of SK2, returned encouraging results. OKU said that this is similar to SK2 some 300m to the south.
Significant intersections included 6m at 2.86g/t gold from 124m, including 3m at 4.90g/t gold from 126m in hole RCSK019-092, and 7m at 1.23g/t gold from 50m in hole RCSK019-091.
OKU said that these new assay results continue to highlight potential to extend the SK2 trend to the north.
Next steps
The company reported that further assay results are expected in the coming weeks from the remaining 36 of the total 53 RC/AC holes drilled to date at SK1-5.
OKU said that the AC, RC and diamond drilling will continue and follow up these results is scheduled to commence in late November 2019.
The company said that following the recent outstanding intersection of 47m at 10.95 g/t gold returned from the northern end of SK1, the Board has approved a program of follow-up drilling to test this emerging zone of high grade mineralisation.
Oklo reported that follow-up drilling is planned to further test the intervening area between SK2 and SK2 North.
The company announced that an additional 27 holes, comprising 26 RC holes and 1DD hole, are planned, with the DD hole now underway.
Management comments
Oklo’s Managing Director, Simon Taylor said: “The Seko gold trends are consistently delivering results beyond expectation and our understanding of the extensive gold system and confidence in unveiling further discoveries is growing by the day. We look forward to reporting the balance of assay results from the shallow drilling program while our deeper drilling phase advances.”
Oklo’s General Manager Exploration, Andrew Boyd said: “These new results from the infill drilling at SK2 have confirmed the presence of a coherent zone of high-grade gold mineralisation. The deeper RC and diamond drilling program is now underway and on the back of recent outstanding results from the far northern end of SK1, including 47m at 10.95g/t gold the program has been increased to further test this zone, where we are optimistic of outlining a new high-grade shoot.”
