• Near-term priorities are updating Mo i Rana mineral resources and exploring and analyzing Haveri deposits.

Mo i Rana and Mofjell

• Mo i Rana includes 42 Norwegian exploration permits and a geological database; the area has an industrial park with 100+ businesses, smelting facilities and a battery factory under construction.

• Mofjell has stated potential of 5 Mt at 3.8% zinc equivalent; a separate asset summary gives 3.16 Mt at 2.5% Zn, 0.4% Pb and 0.3% Cu.

• The former mine produced 4.35 Mt at 3.61% Zn, 0.71% Pb, 0.31% Cu, 10 g/t Ag and 0.3 g/t Au; high-grade gold intersections include 1.4 m at 7.35 g/t and 2.8 m at 3.88 g/t.

• Historical data include 147 drill holes totaling 16,406 m and airborne geophysics covering ~500 km²; modern data analysis and AI-based structural modeling are planned to generate targets.

• Nearby prospects include Hammaren, Hesjelia, Småvatnan and Hellerfjellet; historic rock samples there included over 10% combined Cu-Zn-Pb and over 100 g/t Ag.
