Midnight Sun Mining (MMA ) Corporate presentation summary

Strategic location and opportunity

• Projects are located in Zambia's Domes Region, a globally significant copper exploration hotspot surrounded by major producers and infrastructure, including the Lobito Rail Corridor for export access.

• Zambia offers stable governance, a mining-friendly jurisdiction, and shallow, large-scale copper deposits, making it a top destination for copper exploration and development.

Dumbwa deposit: scale, geology, and progress

• Dumbwa is a large-scale, near-surface, basement-hosted sulphide copper system, geologically analogous to Barrick's Lumwana mine.

• Over 56,855m of drilling completed, defining 6.7km of strike length, with mineralization open along strike and at depth; drilling ongoing at 6,000–10,000m per month.

• Drill highlights include intercepts such as 93m @ 0.40% Cu, 44m @ 0.53% Cu, and 22m @ 1.0% Cu, confirming bulk tonnage potential.

• The deposit features three main mineralized lenses, with average grades of 0.3–0.5% Cu and thicknesses up to 200m, starting at surface.

• Phase one drilling targets 11.5km of strike, with completion expected by Q3 2026.

Geological approach and leadership

• Exploration is led by Dr. Kevin Bonel, who previously expanded Lumwana and applies a proven, data-driven, phased exploration methodology.

• The approach includes geochemical sampling, IP surveys, and systematic drilling to delineate structure and mineralization.
