Oklo Resources (ASX: OKU) has uncovered more than 100 grams per tonne of gold while drilling at the SK1 North discovery in its Dandoko project in west Mali, with results to be incorporated into its upcoming maiden mineral resource estimate.
The Africa-focused explorer today announced the receipt of assay results from a further 29 holes in an expanded resource definition drilling program, which successfully extended SK1 North to 500m in strike length and to a vertical depth of up to 145m.
The drilling returned high-grade gold mineralisation from step-out drilling along strike and at depth, including individual grades of up to 102.37g/t gold over 1m.
It also unearthed wide zones of mineralisation with assay highlights such as 38m at 5.65g/t gold from 159m, including 10m at 19.22g/t gold from 165m, 6m at 30.94g/t gold from 168m, as well as the 102.37g/t interval.
Other significant intersections included 32m at 10.57g/t gold from 52m including 10m at 30.96g/t from 58m; and 8m at 9.25g/t gold from 22m including 2m at 31.85g/t gold from 24m.
Today’s news follows a string of positive drilling results announced in the last few months, including the discovery of gold at the Koko prospect in January and the extension of mineralisation at SK2 and SK3 last week.
Oklo managing director Simon Taylor said the company is delighted with the latest “exceptional results”.
“With SK1 North emerging as a game-changer for Oklo, all efforts are currently being made to fast track its evaluation prior to finalising our maiden [mineral resource estimate],” he said.
Maiden mineral resource estimate
According to Oklo, the expanded reverse circulation and diamond drilling program is ongoing both down dip and along strike to the north to speed up the evaluation of the SK1 North discovery.
SK1 North is expected to be incorporated into Oklo’s maiden mineral resource estimate, which is anticipated within the next three months.
Air core drilling south of Seko towards the Koko discovery is now complete with assay results pending, the company added.
Mr Taylor also noted that drilling at Dandoko has so far remained “unaffected” by the COVID-19 pandemic that has impacted other exploration activity around the globe.
