Material Assumptions

Full details of the bankable feasibility studies for the Arrowsmith North, Arrowsmith Central and Muchea Silica Sand Projects, including material assumptions, are contained in VRX’s ASX announcements of 28 August 2019, 17 September 2019 and 18 October 2019, respectively. All such material assumptions continue to apply and have not materially changed from the date of release of the respective BFS. While VRX considers all of the material assumptions to be based on reasonable grounds, there is no certainty they will be correct or that the range of outcomes indicated within the studies will be achieved.
