Western Copper & Gold

Casino is a large-scale copper-gold-molybdenum-silver porphyry deposit located in west-central Yukon, Canada, wholly owned by Western Copper & Gold. A feasibility study completed in 2022 outlined a 27-year open-pit mine producing an average of 163 million pounds of copper and 186,000 ounces of gold annually. The project is currently advancing through permitting under the Yukon Environmental and Socio-economic Assessment Board, with a comprehensive cooperation agreement in place with the Selkirk First Nation.

Rio Tinto plc acquired a 9.9% equity stake in Western Copper & Gold in 2021 for C$25.6 million and has since increased its holding to roughly 10% (per the firm, 2021). The investment includes an investor rights agreement granting Rio Tinto a technical advisory role through a joint technical committee, anti-dilution rights, and participation rights in future project financing. Rio Tinto does not control the company but provides technical review and validation of the project's potential.

Western Copper & Gold is a pre-production development-stage company. The Casino project has not yet received final permits or a construction decision. The company's activities are currently focused on advancing permitting, completing environmental baseline studies, and maintaining community relationships in the Yukon. Mine construction and first production would follow a positive construction decision, which is not yet scheduled.

Casino is distinguished by its sheer scale, containing 14.5 billion pounds of copper in measured and indicated resources, making it one of the largest undeveloped copper-gold porphyry deposits globally (per NI 43-101, 2022). It is located in a mature, politically stable jurisdiction with existing infrastructure access via the Alaska Highway corridor. The deposit's size and the presence of by-product gold and molybdenum provide economic diversification and a long projected mine life of 27 years.

The company funds permitting and pre-development work through periodic equity financings and had approximately C$32.6 million in cash as of year-end 2024 (per the firm, March 2025). It completed a C$6 million flow-through share issuance in August 2024. The capital structure is equity-based, with no long-term debt. Full project financing for construction would likely involve a combination of equity, project debt, and potential partner contributions, with Rio Tinto holding participation rights.

Paul West-Sells serves as President and has a Ph.D. in metallurgical engineering, having led the company's technical and permitting efforts for over a decade. Sandeep Singh is President & CEO, and previously held the title of CEO. The management team combines mining engineering, permitting, and public-company experience relevant to advancing a single-asset development company. Rio Tinto's strategic stake is governed at the board level, but the company remains independently managed.

The primary risks are permitting delays, commodity-price exposure to copper and gold, and the significant capital expenditure required for construction — estimated in the feasibility study at approximately C$3.3 billion in initial capex. The project is a single-asset concentration for the company. Permitting success depends on continued cooperation with the Selkirk First Nation and satisfaction of Yukon and federal environmental assessment requirements.
