BlackRock is the world's largest asset manager and purchased the majority of its 24.9 million shares at $0.24.
Oklo recently received commitments to raise $8.7 million in a share placement.
Proceeds will primarily be used to accelerate exploration activities over the company’s Mali Gold Projects.
The company's Dandoko and Moussala projects are located within the Kenieba Inlier of western Mali and lie within 30 kilometres of B2Gold’s 5.15 million ounce Fekola project and 50 kilometres of Randgold’s 12.5 million ounce Loulo mine.
Results from the upcoming drilling programs are expected at the Seko discovery within the Dandoko project.
