Infill diamond and reverse circulation drilling at Disse has intersected high-grade primary gold mineralisation with results including:
- 6 metres at 13.05 g/t from 72 metres with the hole ending in mineralisation. Within this was 2 metres at 32.55 g/t, including 1-metre at 39.9 g/t;
- 3 metres at 11 g/t from 101 metres, including 1-metre at 26 g/t; and
- 3 metres at 6.02 g/t from 84 metres, including 1-metre at 16.3 g/t.
Further assay results remain pending from the ongoing resource growth drilling at Seko and follow-up drilling at the recent Sari discovery.
“Emerging high-grade target”
Oklo’s managing director Simon Taylor said: “Since the announcement of our maiden mineral resource estimate, we have remained very focused on testing new targets and previous targets in more detail for their resource growth potential.
“Disse is an emerging high-grade target following the confirmation of potential shoot development in fresh rock to complement the largely shallow oxide resource at Seko.
“We are now busy planning the next phase of drilling and have retained the current drill rig which is scheduled to resume work in September following conclusion of the wet season.
“We look forward to the receipt of outstanding assay results, including from the recent Sari discovery.
“In the meantime, we are completing a 3D IP geophysical survey and passive seismic survey to assist in targeting potential high-grade feeder mineralisation in fresh rock below the extensive oxide mineralisation at Seko.
Location of Oklo’s gold projects in west Mali.
Disse is a southeast-trending zone extending over 550-metre strike length to the south of SK3 that remains open at depth and along strike to the southeast.
Notably, an inferred resource of 150,000 tonnes at 2.57g/t gold for 12,100 contained gold ounces was previously reported for Disse.
Assay results reported are from four reverse circulation (RC) holes totalling 498 metres, one diamond hole (DD) for 181 metres and 21 shallow aircore (AC) holes for 804 metres.

Drilling is paused for the wet season, with the existing drill contract extended for the recommencement of drilling later this month.
Work programs in progress include:
- Technical (scoping) and environmental studies;
- Compilation of all outstanding assay results and planning for the next phase of drilling;
- Detailed surveys to assist in targeting potential high-grade feeder zones in the fresh rock below the extensive oxide mineralisation at Seko including a 3D IP geophysical survey over the SK1 and SK2 deposits; and
- A passive seismic survey covering 30 square kilometres over the Seko resource area and immediate extensions to the north and south.
