Constantine’s flagship Palmer Project (Zn, Cu, Au, Ag) is situated in Southeast Alaska, USA - a proven and profitable mining jurisdiction, historically productive and currently, highly prospective.

The Palmer Project is located in a very accessible part of coastal Southeast Alaska and within the Porcupine Mining District, an area with active placer mining and logging. Nearby logging roads and a paved Alaska State Highway provide access to the year round deep-sea port of Haines, and Pacific Ocean access to Asian concentrate markets.

A Preliminary Economic Assessment was completed on the Palmer project in June 2019 (and filed July 18, 2019), amended March 7, 2022 and filed March 11, 2022 on, which presents a low capex, low operating cost, high margin underground mining operation with attractive environmental attributes.
