Drilling is ongoing at Seko, Koko and other extensions to the Dandoko gold system in advance of finalising a maiden mineral resource estimate during the current quarter.
A further 143 holes have been completed with assay results pending.
Further unlocking potential
Oklo managing director Simon Taylor said: “We are encouraged by the latest results from SK1 South with the deepest hole drilled to date intersecting a thick zone of medium-grade gold mineralisation.
“Additionally, the most southern line at SK1 South continues to extend this zone, which will be further tested along strike to the south and at depth.
"These results coupled with the emergence of a new high-grade zone at SK4 some 700 metres to the northeast of SK1 bodes well for further drilling success at Seko.
"With the current drilling campaign in full swing, we look forward to further unlocking the potential of the Dandoko gold system.”
Assay results were from step-out and infill resource drilling at SK1 South and SK4, about 700 metres northeast of SK1.
SK1 South has been extended to a vertical depth of about 150 metres and remains open along strike to the south with follow-up drilling in progress.
The current program is focused on completing the oxide zone definition drilling in advance of finalising the maiden resource estimate.
Latest assay results have successfully extended SK1 South at depth, returning the deepest intersection to date.
Significant intersections include:
► 30 metres at 3.16 g/t gold from 162 metres (to end of hole), including 7 metres at 9.68 g/t that in turn includes 2 metres at 19.64 g/t with the hole ending in mineralisation;
► 10 metres at 4.04 g/t from 11 metres, including 3 metres at 8.30 g/t;
► 5 metres at 5.36 g/t from 86 metres, including 2 metres at 11.89 g/t;
► 10 metres at 2.42 g/t from 47 metres, including 2 metres at 6.69 g/t; and
► 12 metres at 1.05 g/t from 40 metres, including 2 metres at 4.40 g/t.
These results confirm SK1 South remains open along strike, with drilling ongoing to further extend this zone to the south.
Located about 700 metres north-east of SK1 North, a follow-up hole drilled in the current campaign successfully intersected a shallow high-grade gold zone, returning 2 metres at 11.97 g/t gold from 21 metres downhole, which will be further investigated.
Drilling program on track
Following an initial delay in its initial 15,000 metres drilling program, which started in late October 2020, due to the late arrival of two of the three drill rigs, the program is now back on track.
After working double shifts over the New Year period to increase the daily meterage rate, a total of 14,650 metres has been completed.
Subject to the timely receipt of assay results, the completion of the MRE is expected during the current quarter.
A further 143 holes have now been completed with assays pending.
With the easing of in-country restrictions by the Malian government, the company has resumed normal staff and contractor rotations and break schedules, including expatriate staff, with all international borders now open.
The company will continue with the measures implemented during the COVID-19 pandemic including health screening and temperature monitoring, change in rosters, social distancing protocols, a change in flow of staff to and from local communities, and the minimisation of staff in the Bamako administrative office.
