Orion Minerals Limited announced an updated total Mineral Resource comprising Indicated and Inferred Resources of 30.49Mt grading 3.7% Zn and 1.2% Cu at its Prieska Zinc-Copper Project (Prieska Project) in the Northern Cape, South Africa, following the completion of an updated Mineral Resource estimate for the +105m Level Target (Open Pit). The new total Mineral Resource follows the landmark upgrade to the Deep Sulphide Mineral Resource announced just before Christmas and the subsequent Scoping Study which confirmed a robust Phase 1 development for the Prieska Project. The total Mineral Resource will be incorporated in the Bankable Feasibility Study (BFS) due for completion in Second Quarter 2019. Updated +105m Level Mineral Resource: Since the first +105m Level Mineral Resource announcement, the geological wireframe and resource estimate have been updated to include additional drill data and refinements to modelling of metallurgical zonation to re-evaluate the model. The changes to the Mineral Resource estimate have successfully increased the total +105m Level Mineral Resource to 1.76Mt grading 2.0% Zn and 1.5% Cu, with 0.62Mt grading 3.05% Zn and 1.54% Cu of the Mineral Resource classified in the higher-confidence Indicated category. The +105m Level Mineral Resources are based on drilling data available for the Repli Prospecting Right.
