Standout aircore drill results included 42 metres grading 6.14 grams per tonne gold from surface and 30m at 4.47gpt, also from surface.

Oklo said the results “further confirm our belief that the Seko gold discovery has the potential to host a significant, shallow gold resource”, with RC drilling now underway.

Seko is part of the Dandoko project, with the junior’s adjoining Moussala and Kouroufing exploration projects located within the Kenieba Inlier of western Mali and within 30km of B2Gold’s 5.15 million ounce Fekola Project and 50km of Randgold’s 12.5Moz Loulo Mine.

The phase one program is expected to be completed by the end of January 2018 at an estimated cost of $3.5 million.

Oklo started the current quarter with $12.8 million cash.

Shares in the company were up 15.6% to 37c in midday trade, capitalising Oklo at $106 million.

The company’s shares are up about 300% on levels 12 months ago.
