OKO WEST PROJECT
The Project area is in the Cuyuni Mining District, some 95 km west of Georgetown and easily accessed by bush roads and trails from the city of Bartica or by boat using the Cuyuni river (Figure G1).
Mineral rights and agreement
The Oko West Project comprises an assembly of nine medium-scale mining permits covering an area of 9,420 acres, held by a Guyanese entrepreneur. Reunion has entered into an agreement entitling it to conduct exploration activities and acquire the Project until August 2026. This Project is part of the portfolio being explored as part of the Strategic Alliance with Barrick Gold and is deemed to be held 50-50 with Barrick.
Geology and mineralisation
The Oko permits are underlain by a greenstone assemblage of Proterozoic rocks of the Barama Group consisting of volcanics and clastic sediments intruded by felsic plutons, strongly deformed by at least one tectonic event, and metamorphosed to greenschist facies (Figure O1). Known gold mineralization appears to be preferably focused along structures at the contacts of volcanic and granitic bodies and have been artisanally mined in alluvial flats and pits in saprolite material.
In 2019 Reunion completed geological mapping and the stream sediment sampling of relevant drainage in the Project area and is currently covering it with a detailed magnetic and radiometric airborne survey. The anomalies generated by this work will be explored using regolith geochemistry, trenching, and drilling in 2020.
