Slide 5: Initial Discovery and Development
The Laver Story Initial Discovery and Development 1929 ‒ A Cu-rich boulder was found about 10 km south east of Laver by Boliden exploration. 1930 ‒ Laver deposit was discovered. 1933 ‒ The company decided to open the Laver Mine ‒ The average grade of the Laver deposit was in fact too low but t
Slide 6: Historical Production
The Laver Story Historical Production Mining was performed in small open pit but primarily underground. The Laver mine operated between 1938-1946. The ore consisted of narrow zones with “high” Cu-grade. In total 1.3 Mt @ 1.5% Cu, 0.2 g/t Au and 36 g/t Ag was mined. Boliden CMD 2012 6 2012-11-2

Slide 17: Appendix: Mineral resource (JORC)
Appendix Mineral resource (JORC) A „Mineral Resource‟ is a concentration or occurrence of material of intrinsic economic interest in or on the Earth‟s crust in such form, quality and quantity that there are reasonable prospects for eventual economic extraction. The location, quantity, grade, geologi

Slide 22: Geology: Rock types and mineralization
The Laver story Geology Rock types and mineralization Laver consists mainly of ca 1.9 Ga old volcanic rocks. The mineralization comprise mainly of sulphides in dissemination and veins. The main minerals are chalcopyrite, pyrrhotite, pyrite, molybdenite, magnetite and sphalerite. Boliden CMD 2012
Slide 23: Continued drilling: Inferred Mineral Resource
• Continued drilling • Potential volume and grades can be estimated • Too spaced drilling to allow interpretation of geological continuity • Inferred Mineral Resource Boliden CMD 2012 23 2012-11-23
