Location and Geology
The Kouri Project is located 230km NE of Ouagadougou. It covers an area of 325km2. The Project is located on the Samira Greenstone Belt which, in the project area, comprises a package of andesitic volcanics with minor intervals of felsic and mafic volcanics and fine-grained metasedimentary rocks. The greenstone belt is flanked to the north and south by granite-gneiss domains.
The Project lies on a major mineralised fault zone that extends to the NE into western Niger, where the 2.5Moz Samira Hill gold deposit is located. To the SW, the faultz zone is connected to the Markoye Fault system which controls a number of major gold deposits in Burkina Faso, including Kiaka (5.9Moz gold, B2 Gold), Bomboré (5.2Moz gold, Orezone) and Essakane (6.2Moz gold, IAMGOLD).
The mineralisation within the Kouri Project consists of multiple, sub-parallel northeast striking and moderate to steeply northwest-dipping structures within the regional fault system. The shears are hosted within highly altered volcanic and volcaniclastic rocks and are associated with a major gold in soil geochemical anomaly along an inferred dilational jog along the northeast-trending shear zone. Gold mineralisation occurs within extensional gash quartz veining, in quartz stockwork veining between shears and disseminated in highly-altered host rocks. Gold mineralisation also occurs in the sheared contacts between granite intrusives and greenstones.
Golden Rim has been conducting exploration activities in the Project area since 2013. Work has included geological mapping, rock-chip sampling, ground magnetic and Induced Polarisation (IP) geophysical surveys, auger geochem drilling and approximately 76,900m of reverse circulation drilling and diamond drilling.
