Highlights: ? Strongly value accretive proposition for development of in-situ operations (initially Silver King and East Fault Block) alongside current tailings operations at Century ? Attractive in-situ operation economics (incremental to tailings): o At base case: Pre-tax NPV8 A$212M, IRR 102%, payback 2.2 years1 o At current spot: Pre-tax NPV8 A$234M, IRR 111%, payback 2.0 years2 ? Increased zinc output and production of a new lead product with silver credits: o Average lead metal (in-concentrate) production output of 33,000tpa, containing 972,000oz pa silver o Average additional zinc metal (in-concentrate) production output 22,000tpa ? Premium lead concentrate product, grading 65–70% lead and 500-600g/t silver, providing attractive offtake finance options ? In-situ operation reduces Century wide C1 costs by US$0.21/lb payable zinc, through the benefit of additional lead, zinc and silver metal output spread over Century’s existing significant sunk capital base (in-situ operation C1 -US$0.49/lb payable zinc) ? Estimated pre-production capital of A$66.7M, with cost spread over the first ~15 months from initiation of project development ? Final Investment Decision (FID) to follow amendment to existing environmental approvals and completion of financing and joint venture assessment process ? Next steps: o Completion of Board approved Front End Engineering Design (FEED) works, operational readiness and long lead item procurement o Targeting FID in Q1 CY2022 and first production in Q1 CY2023
