The project’s overview
Oko West is a gold project currently in construction, with a 68 km² land package located in Cuyuni-Mazaruni, Guyana, approximately 95 km west of Georgetown.
G Mining Ventures is building Guyana’s next leading gold mine, with a projected 12 year mine life and over 4.6 million ounces of reserves. Once completed, the mining method will include both open pit and underground operations.
About the project
Location
The Oko West Project straddles the Cuyuni-Mazaruni Mining Districts (administrative Region 7) in north central Guyana, South America. The Project is located approximately 95 km southwest of Georgetown, the capital city of Guyana and approximately 70 km from Bartica, the capital city of Region 7.
Geology & Mineralization
The Oko West gold deposit is located in the north-central Guyana Shield, along a north–south striking contact between the Barama-Mazaruni Supergroup greenstone belt to the west and the Oko pluton to the east.
Gold mineralization at Oko West is characteristic of orogenic gold systems and occurs primarily within volcanoclastic, siliciclastic, and carbonaceous sedimentary rocks forming a tabular body dipping gently to the east.
The mineralized zones exhibit strong silica and carbonate alteration, pervasive sericitization, and disseminations of sulfides (pyrite, chalcopyrite, sphalerite) within altered rocks, bedding planes, fractures, and quartz–carbonate vein envelopes. Much of this alteration is pre-mineral, strengthening the host rocks and facilitating brittle deformation and dilation during the D₂ mineralizing stage.
Gold and sulfide mineralization are associated with networks of sulfide-bearing quartz veins and sulfide-only stringers spatially related to quartz–carbonate vein systems that partially to fully overprint the host lithologies. In carbonaceous sediments, these veins are dark grey to smoky, whereas in volcanoclastic and siliciclastic units, they are white to light grey. The darker color in the carbonaceous units likely reflects a geochemical interaction between carbonaceous material and hydrothermal fluids, which acted as a reducing agent enhancing gold deposition and resulting in locally high-grade gold zones.
