Metallica Minerals Limited announced that it has successfully completed a twenty-four (24) hole infill drilling program at its 100% owned Cape Flattery Silica Pty Ltd. (CFS) project. Hole depths averaged approximately 16m with a maximum depth of 36m being drilled in hole CFS142. These holes were drilled within the CFS Mining Lease Application area (MLA) using a vacuum-based drill rig. The combined database for the CFS Project now comprises 144 drill holes comprising approximately 2,000m of drilling. High purity silica sand was intersected in 17 of the 24 holes with the high-grade sand occurring consistently as predicted by the resource model. The infill drilling indicates that the existing geological model is robust. The chip tray samples from hole CFS142 (being 36m in depth). This sample shows a high proportion of clean white sand. Metallica's team of consultants are progressing well towards the completion of the Pre-Feasibility Study (PFS) in first quarter of 2022. The PFS is designed to demonstrate the economic potential of the Cape Flattery Silica Sand project and to build on the successful results of the Updated Scoping Study, which estimated a project NPV of $235 million (before tax) over a 22-year mine life and IRR of 38%. The PFS will provide further detail on the mine design as well as infrastructure required for building the operation. Planning is also underway for a Definitive Feasibility Study (DFS) that is anticipated to follow completion of the PFS. Regular site visits are being conducted by the independent environmental consultants. Aquatic and Marine studies have been completed with reports being prepared for inclusion to the Environmental Application submission planned for early 2022. Surface and Ground water monitoring continues with data being collected to establish baseline parameters.
