if copper keep going like this and tops $5 lot of people will start paying attention to ALK. Cadia is about 80% Au and 20% Cu (roughly) and Northparks is about 80% Cu and 20% gold (again very rough) while NMPP is about 60% Au and 40% Cu which is probably best balance as it allows to gain in value from either.
Gold made massive gains and NMPP should rise in value because of that. Now Copper is doing same while gold keeps the highs. Cadia won't be benefiting too much from the Cu gains where Northparks won't be benefitting too much from gold price gains. NMPP gains from both as it contains decent % of each.
