Estimated Strip Ratio'sThis information was quoted from the critical investor dated Nov 2, 2022. These strip ratio's will probably continue to come down as new resources are revealed in the coming months. Wenot east has some very very good potential and more than likely near surface mineral resources.
CEO Ellingham commented the following about my estimates on strip ratio, and general remarks on potential LatAm water inflows: “For resource estimates the constraining pit is not an engineered pit design, that comes later during the Preliminary Economic Assessment (PEA). A lot of the western Wenot mineralization is shallow so will bring down any overall strip. For the main part of the pit, probably a 6-8 strip ratio is a good guess, but as we expand on the zones east and west, the average strip will continue to come down. Regarding the pit slopes, when Wenot was in production the north pit slope (in the volcanics) was above design at over 60 degrees. Guyana has a lot of rainfall, but Omai operated for many years with no major recorded issues on the rainfall or inflows, although they had facilities in place for ongoing control.”
