Oklo Resources : Highly Encouraging Drilling Results Leads to Program Extension

21 FEBRUARY 2017

► Phase 1 40,000m auger geochemical and 7,000m RC drilling program at the Dandoko and Moussala Projects extended following receipt of positive assay results

► Phase 2 drilling campaign for a further 25,000m of infill auger, AC and RC drilling approved and underway

► Auger assay results received to date successfully outline extensive new gold anomalies at Seko, including:

o a western coherent trend extending over 1.6km with grades of up to 3.28g/t gold; o a central parallel ~2.0km long gold trend with grades of up to 2.42g/t gold; and o further anomalous zones of over 800m in length.

► Infill drilling by two auger rigs in progress at Seko in preparation for deeper aircore drilling

► First batch of RC assays received from RC drilling at the Diabarou and Disse prospects

► At Diabarou, significant results from step-out drilling of the main high grade, east-west trending gold zone on 100 metre spaced lines included:

► 2m at 50.00g/t gold

► 8m at 2.08g/t gold

► 2m at 9.08g/t gold

► 10m at 1.28g/t gold

► Results from a further 8 holes drilled at the Disse prospect remain outstanding

► Drilling activities fully funded from existing cash reserves of circa $7.0 million

The Dandoko and Moussala Projects are located within the Kenieba Inlier of western Mali and lie within 30km to the east of B2Gold's 5.15Moz Fekola Project and 50km to the south-southeast of Randgold's 12.5Moz Loulo Mine.

The recently completed 40,000m reconnaissance auger geochemical program was designed to improve the geological and geochemical understanding of prospective target areas within the Dandoko and Moussala projects by cheaply and efficiently penetrating below the extensive tracts of lateritic and transported cover.

Assay results received from the auger drilling campaign at Dandoko have successfully outlined new and encouraging zones of strong gold anomalism, most notably at the Seko area (refer ASX announcement of 30 January 2017), which are interpreted to be related to prospective NE- trending, regional-scale structures.

The location of all completed and planned holes along with assay results received to date are presented in Figures 2 and 3.

The auger assay results at Seko have successfully outlined several new significant gold anomalies, including:

► a western coherent trend extending over 1.6km with grades of up to 3.28g/t gold;

► a central parallel ~2.0km long gold trend with grades of up to 2.42g/t gold; and

► further anomalous zones of over 800m in length.

A number of additional extensive >150ppb gold anomalies have been identified from first pass drilling on a 400m line spacing and are now the subject of infill auger drilling.

Assay results are also pending from the south of the Dandoko project and from Moussala and will be released when coherent blocks of data become available.

To date, a total of 3,897 auger holes for 44,946m have been completed at Dandoko along with 520 holes for 5,441m at Moussala at an average hole depth of 11m.

Follow-up auger drilling has been approved by the Board as part of the Phase 2 campaign comprising a further 25,000m of auger, AC and RC drilling, with two auger rigs currently dedicated to infill drilling of the new Seko trends in advance of AC drilling.

It is anticipated that the infill assay results will be available by early March in advance of a planned AC drilling program.
