Oklo’s Moussala permit is strategically located within the prolific Kenieba Inlier approximately 15km to the west of Oklo’s Dandoko Project and 15km east of B2Gold’s 7.1Moz Fekola gold mine.
The 66km2 permit covers Birimian meta-volcanic and meta-sedimentary rocks intruded by felsic and mafic igneous rocks. The Company considers the project is highly prospective for the discovery of gold mineralisation associated with NNE-trending splay faults off the main, regional-scale Senegal-Mali Shear Zone (“SMSZ”). Elsewhere, these splay faults are spatially associated with no fewer than six major gold deposits in the Kenieba Inlier, including Sadiola (13.5Moz) and Loulo (12.5Moz), and have been interpreted within the Moussala permit from regional aeromagnetic data.
There has been limited modern day exploration completed within the project and no drilling. Results from two programs of soil sampling previously completed in 1997 and 2011 delineated a number of gold-in-soil anomalies with a peak value of 542ppb gold (equivalent to 0.542g/t gold).
Initial desktop studies by Oklo identified numerous, large geochemical, geological and structural targets considered prospective for gold mineralisation. Some of these targets trend in a northeasterly direction remain open ended. Reconnaissance field work comprising mapping, sampling of artisanal mining sites, soil geochemistry over previously untested target areas and infill soil sampling has been completed.
During mid 2017 auger drilling (1,638 holes for 19,850m) was completed on a 400m x 100m spacing, to evaluate the previously outlined geochemical and geological targets.
The auger drilling campaign successfully outlined further encouraging zones of gold anomalism interpreted to be related to prospective regional structures including the Dakadia, Dakadia South and Brundoto prospects. Dakadia, is the largest anomaly spatially and sits on the intersection of two large regional NNE and NE structural trends.
