- Doré Copper Mining Corp. Doré Copper Mining Corp. is a Canada-based copper-gold exploration and development company focused on advancing high-grade brownfield projects in the prolific Lac Doré/Chibougamau and Joe Mann mining camps of Québec. The company holds a consolidated land package spanning approximately 60 kilometers around its Copper Rand Mill, including 13 former producing mines, deposits, and resource target areas that have historically yielded 1.6 billion pounds of copper and 4.4 million ounces of gold; its core assets encompass the Corner Bay copper-gold deposit, Joe Mann past-producing gold mine, Devlin copper deposit, Cedar Bay past-producing copper mine, Copper Rand past-producing copper mine and mill, and additional exploration targets such as Gwillim, Doré Ramp, Jaculet, and Cedar Bay Southwest Zone Extension. Doré Copper Mining Corp. primarily explores for and develops copper and gold mineral properties through a hub-and-spoke operating model that leverages the refurbished Copper Rand Mill as the central processing facility with capacity for its own ore and potential toll milling services; it targets initial production of over 50 million pounds of copper equivalent annually from key deposits including Corner Bay, Devlin, and Joe Mann, supported by a positive preliminary economic assessment completed in May 2022 that outlines low initial capital costs of C$180 million and a mine life exceeding 10 years. Founded in 2017 and headquartered at 130 King Street West, Suite 1900, Toronto, Ontario, the company operates exclusively in Québec, Canada, with measured and indicated mineral resources of 3.6 million tonnes at 3% copper equivalent and inferred resources of 7.2 million tonnes at 3.8% copper equivalent across its projects. In a transformative development completed by December 31, 2024, Doré Copper Mining Corp. merged with Australia-based Cygnus Metals Limited in a C$23-24 million merger-of-equals transaction via a court-approved plan of arrangement, under which Cygnus acquired all outstanding shares and now operates as its parent company, creating a dual-listed critical minerals entity on the TSX Venture Exchange, Australian Securities Exchange, and OTCQB with combined copper-gold and lithium assets; the merger provides enhanced funding and expertise for advancing the Chibougamau Copper-Gold Project toward production, including a planned 2025 exploration drilling campaign, while former Doré shareholders hold 45% of the merged group and the board features equal representation from both entities.
