Cerro Las Minitas SouthernSilver EXPLORATION CORP Potential Economic Updates The PEA has modelled robust annual average cashflow particularly in the first eight years of mine-life. New work will focus on increasing free cash flow within the current model Adding Additional Resources: • New resources added at North Felsite in 2023 to be incorporated into the mine design. Other areas with exploration potential include: ➤North Skarn Down-dip extensions of the eastern deposits Engineering Upgrades: Higher payable subsets of the Mine Production Schedule to be evaluated • Modified sub-blocking routine Capital Cost/Contingency Reduction: • Full vetting of the Cash-flow model has identified additional cash saving opportunities Process Flow-sheet - TC-RCS/Gold Metallurgy: Gold is not included as a payable in the current processing flowsheet; currently working to define gold payables • New metallurgical results consolidates the process flow sheet to reduce the TCS-RCS Oxide mineralization: Au-Ag-enriched oxide mineralization is not included in the flowsheet and could be used to augment recovered gold from the pyrite-arsenopyrite-concentrate Ore-Sorting: • Positive initial test results suggest significant waste rejection and retention of mineral value.
