| Description |
New lead isotope data and published data used to determine relationships between mineral resources and magmatic events, identify a magma source for the intrusions and volcanic rocks, and a metal source for the base metal veins. Base metal vein metals were sourced from intrusions that assimilated upper crustal material. Intrusions originated from Archean-Proterozoic mafic to intermediate basement that assimilated upper crust.
