About Dore Copper Mining Corp.

Dore Copper aims to be the next copper producer in Quebec with an initial production target of greater than 50 million pounces of copper equivalent annually by implementing a hub-and-spoke operation model with multiple high-grade copper-gold assets feeding its centralized Copper Rand mill (1). The company has delivered its preliminary economic assessment in May, 2022, and is proceeding with a feasibility study.

The company has consolidated a large land package in the prolific Lac Dore/Chibougamau and Joe Mann mining camps that have historically produced 1.6 billion pounds of copper and 4.4 million ounces of gold (2). The land package includes 13 former-producing mines, deposits and resource target areas within a 60-kilometre radius of the company's Copper Rand mill.
