Oklo’s follow-up drilling has confirmed and extended the Sari gold discovery just 10km from its 670,000oz Seko resource in Mali.

Mineralisation is now proven to extend into the fresh rock below the discovery hole with hits such as 7m grading 2.64 grams per tonne (g/t) from 42m including 2m at 8.1g/t gold and 11m at 1.02g/t gold from 65m.

In addition, near surface gold mineralisation has been intersected along strike with notable results such as 3m at 6.8g/t gold from 6m, 18m at 1.18g/t gold from 45m including 3m at 2.46g/t gold, and 12m at 1.08g/t gold from 30m that ended in mineralisation.

Oklo Resources (ASX:OKU) notes that all intersections are at the northern end of a 2.4km auger gold-arsenic geochemical anomaly along the western margin of a prominent radiometric feature that has been interpreted as an intrusive.

There’s further potential to grow the company’s Mali gold inventory given that a comparable untested target extending over 6km located to the east of the interpreted intrusion within the company’s Kossaya project will be tested by drilling in the near term.

“We are delighted to report further success from this emerging target at Sari. The latest results are from 100m spaced step-out drill traverses to the north and south of the initial discovery hole announced in May 2021 that returned 24m at 1.97g/t gold from 12m,” managing director Simon Taylor.

“Additionally we have confirmed depth continuation below the discovery hole and as such Sari remains very much open in all directions.

“Importantly, Sari is located within 10km of Seko so it is within reasonable trucking distance of the 0.67 million ounce mineral resource and as such, will form an important part of our current resource growth initiative.

“The results also highlight the prospectivity of our 500sqkm landholding in west Mali where our main focus continues to be on unlocking additional growth opportunities within Dandoko and other regional targets.”

Sari drilling

Oklo’s 1,988m of follow-up drilling at Sari is part of its aggressive resource growth initiative that was started after the initial Dandoko resource estimate was announced in late March 2021.

The bulk of this drilling targeted immediate extensions along strike and at depth of Seko, and other geochemical and geophysical targets (induced polarisation) along the 15km Dandoko gold corridor and adjoining project areas including Sari.

Drilling at Sari included two traverses of aircore holes that successfully intersected gold mineralisation at shallow depths and confirmed a north-south trend to the gold mineralisation.

Meanwhile, the depth extension was confirmed by an RC hole that was drilled below the discovery hole.

Adding further interest, previous mineralised intervals scanned using portable XRF demonstrated elevated arsenic and sulphur levels as well as moderate nickel, copper and lead levels, a geochemical signature that is a feature of gold mineralisation at the Seko SK1N deposit.
