Following the announcement of the discovery hole within the Sari Project in May 2021, the company has completed 1,988 metres of follow-up drilling.
New assays have been received from step-out aircore (AC) drilling and an initial deeper reverse circulation (RC) hole under the previously reported intersection at the project.
Latest results from fresh rock below the discovery hole include 7 metres at 2.64 g/t gold from 42 metres including 2 metres at 8.10 g/t and 11 metres at 1.02 g/t from 65 metres.
Other strong assays from Sari are:
- 3 metres at 6.80 g/t from 6 metres;
- 18 metres at 1.18 g/t from 45 metres including 3 metres at 2.46 g/t;
- 3 metres at 3.41 g/t from 27 metres with the hole ending in mineralisation; and
- 12 metres at 1.08 g/t from 30 metres which also ended in mineralisation.
“Delighted to report success”
Oklo’s managing director Simon Taylor said: “We are delighted to report further success from this emerging target at Sari.
“The latest results are from 100 metres spaced step-out drill traverses to the north and south of the initial discovery hole announced in May 2021 that returned 24 metres at 1.97 g/t gold from 12 metres.
“Additionally, we have confirmed depth continuation below the discovery hole and as such Sari remains very much open in all directions.”
Resource growth initiative
After announcing the initial Dandoko mineral resource estimate in late March 2021, the company has embarked on an aggressive resource growth initiative.
The bulk of this drilling targeted immediate extensions along strike and at depth of Seko and other geochemical and geophysical targets (IP) along the 15kilometres Dandoko gold corridor and adjoining project areas including Sari.
Sari is an auger gold-arsenic geochemical anomaly extending over 2.4 kilometres and corresponds to the contact of an interpreted intrusion associated with a pronounced potassium radiometric low.
Extends gold discovery
The step-out drilling has extended the recent gold discovery within Sari, which is around 10 kilometres southeast of the Seko mineral resource.
All intersections are at the northern end of a 2.4-kilometre auger gold-arsenic geochemical anomaly along the western margin of a prominent radiometric feature interpreted as an intrusive.
Taylor said: “Importantly, Sari is located within 10 kilometres of Seko, so it is within reasonable trucking distance of the 0.67 million ounces mineral resource and as such, will form an important part of our current resource growth initiative.
“The results also highlight the prospectivity of our 500 square kilometres landholding in west Mali where our main focus continues to be on unlocking additional growth opportunities within Dandoko and other regional targets.”
Drilling at Kossaya
Previous mineralised intervals were scanned by a handheld portable XRF and showed elevated arsenic and sulphur levels as well as moderate nickel, copper and lead levels.
According to the company, this geochemical signature was a feature of the gold mineralisation at the Seko SK1N deposit.
A comparable untested target extending over 6 kilometres is in the east of the interpreted intrusion within the company’s Kossaya Project and will be tested by drilling in the near term.
