PROJECTS

The Buchans district

Two flagship assets and a wider pipeline of copper-zinc and gold opportunities in central Newfoundland. Lundberg’s 2026 Mineral Resource Estimate comprises 26.08 Mt Indicated at 0.87% CuEq and 0.87 Mt Inferred at 1.54% CuEq. Historical estimates at satellite deposits are presented separately and are not current Mineral Resources.

BUILDING THE DISTRICT

From first claim to funded program.

2020

Wilding gold project acquired

Canterra's first major gold project in Newfoundland, sitting right beside the large Valentine gold project.

2021

Buchans district projects expanded

Acquired resource-stage projects to advance from greenfields through explorer and into advanced exploration.

2023

Buchans acquisition completed

Added the past-producing Buchans mine and made Canterra one of central Newfoundland's larger explorers.

2024

Buchans becomes the flagship asset

The current resource estimate at Lundberg gave the historic Buchans camp a modern base to grow from.

2025

Regional targeting advanced

Deep geophysics and follow-up work identified new drill targets at Buchans and across the wider region.

2026

Funded exploration program underway

Current work focuses on growing the Lundberg deposit, expanding Wilding, and prioritising the rest of the region for future drilling.

Recent drilling, target development, and district-scale updates.
