Lorraine is a copper-gold porphyry deposit (6.4 Mt indicated resource at 0.61% copper and 0.23 g/t gold,
and 28.8 Mt inferred resource at 0.45% copper and 0.19 g/t gold) in north-central British Columbia—one of the youngest known alkalic porphyry deposits within the Triassic-Jurassic Quesnel arc. The deposit is hosted by
the Early Jurassic Duckling Creek Syenite Complex, an alkalic multiphase intrusive dike complex of pyroxenite,
syenite, and monzonite composition.
