NorthIsle Copper and Gold (NCX) Corporate presentation summary

Project overview and value proposition

• District-scale copper-gold project with significant re-rating and growth potential, leveraging both historical data and modern technology for exploration and development.

• $155 million raised in six months to accelerate development, with the largest exploration program planned for 2026.

• Scarcity of large-scale, independent critical mineral investment opportunities in the Americas.

• Strong alignment with First Nations, government, and community, supporting accelerated regulatory timelines.

• Major infrastructure, including roads, power, and ports, already in place due to legacy mining and logging activity.

Project economics and development

• 2025 PEA base case shows $2.0 billion NPV (7%), 29% IRR, and 1.9-year payback at conservative commodity prices.

• Mine life of 29 years with annual production of 157 Mlbs CuEq and 307 koz AuEq.

• Phased development approach lowers initial capital intensity and supports rapid payback, funding Phase II expansion.

• Project economics highly leveraged to copper and gold prices, with NPV rising to $3.8 billion at February 2025 spot prices.

• Positioned in the lowest quartile for capital intensity and cash costs among global copper projects.

Exploration and resource growth

• Integrated resource update increased indicated resources by 60% in tonnage and 132% in gold ounces over previous estimates.

• Systematic, multi-pronged exploration strategy with ongoing drilling and data collection across a 40 km porphyry belt.

• High-grade, gold-rich intervals discovered at Northwest Expo, with strike length extended to 1.1 km.

• West Goodspeed area now defined over 1.2 km strike, with multiple significant copper and gold intercepts.

• Pemberton Hills confirmed as a large-scale porphyry target, with alteration scale comparable to major global deposits.
