Corporate Presentation – December 2024

Presentation Highlights:

• Doré Copper Mining (TSXV: DCMC) has entered a transformative merger with Cygnus Gold, expanding an existing portfolio of high-grade copper and gold assets with lithium assets and better scale and financing capacities. Doré’s production pipeline and exploration potential now spans both mine-friendly Quebec and a new tier-one jurisdiction in Western Australia.
• The Preliminary Economic Assessment (PEA) showcases a 10.5-year mine life with annual production of 53MM lb of Copper Equivalent (CuEq) concentrate. Supported by a robust 2.98% CuEq grade, the project includes an after-tax NPV of CAD 193MM and a 22.1% IRR, with a payback period of just 4.2 years. At current spot prices, these economics are poised to climb.
• Strategically, the historic Copper Rand mill is poised to process 1,350 tons per day utilizing a profitable hub-and-spoke operation within centralized mills and integrating feed from three high-grade deposits: Corner Bay, Devlin, and Joe Mann. With substantial inferred resources still to be tapped and the addition of Cygnus’ assets in Western Australia, the company is positioned for value creation.
