Midnight Sun Mining (MMA ) Corporate presentation summary

Strategic location and opportunity

• Operates in Zambia's Domes Region, a globally significant copper exploration hotspot surrounded by major producers and infrastructure, including the Lobito Rail Corridor.

• Region hosts five of Africa's largest copper mines and contributes 75% of Zambia's export earnings.

• Zambia offers stable governance and favorable mining regulations, supporting large-scale, near-surface copper deposits.

Flagship Dumbwa target

• Dumbwa is a newly discovered, large-scale, basement-hosted sulphide copper system, geologically analogous to Barrick's 1.6B tonne Lumwana mine.

• Features a 20 km copper-in-soil anomaly with grades up to 0.73% Cu and nearly 5 km of drilled strike established.

• Aggressive drilling program ongoing at 10,000m per month, with over 35,000m drilled and initial 12 km targeted for completion by Q3 2026.

• Drill results include intervals such as 22m @ 1.0% Cu, 39.7m @ 0.51% Cu, and 25m @ 0.89% Cu, confirming the model.

• Mineralization starts at surface, with average thickness of 175–200m and grades similar to Lumwana.

Kazhiba Main and near-term production

• Kazhiba Main is a high-grade, near-surface oxide copper deposit with a maiden resource of 2.33Mt at 1.41% Cu (Indicated, 0.10% cut-off).

• Drill highlights include 21m @ 10.69% Cu and 26m @ 5.6% Cu.

• Deposit is acid-soluble malachite, suitable for heap leach, and located within 30m of surface.

• Monetization of Kazhiba Main is planned to fund ongoing Dumbwa exploration without further dilution.
