Interview with Andrew Dennan, CEO of Halo Minerals

Recording date: 16th June 2026

Halo Minerals has emerged as a unique opportunity within the junior mining sector by focusing on the reprocessing of historical mine tailings rather than pursuing conventional greenfield mine development. Its flagship Playa Verde Project in Chile aims to recover copper and gold from legacy tailings deposits while simultaneously addressing a long-standing environmental liability.

The company's most important achievement to date is securing approval of the project's Environmental Impact Assessment (EIA). For mining projects in Chile, permitting is often one of the largest barriers to development, creating uncertainty around timelines and project viability. With the EIA approved and formal written resolution received, Halo has substantially reduced a key project risk and can now focus on financing, engineering, and execution.

The economics outlined in the recently published Competent Person's Report are compelling. The Playa Verde Project contains ore reserves of 32.2 million tonnes grading 0.25% copper, representing approximately 80,000 tonnes of contained copper. Using assumptions of US$5.30 per pound copper and US$4,300 per ounce gold, the project generates a post-tax NPV10 of approximately US$154 million and an estimated IRR of around 51%. These metrics compare favorably with the company's current valuation and suggest meaningful leverage to successful project development.

Importantly, Halo is not relying on experimental technology. Management intends to utilize well-established dredging, flotation, and SX-EW processing methods that have been deployed successfully across the mining industry for decades. This reduces technical uncertainty and may improve financing prospects compared with projects dependent on novel extraction technologies.

The broader copper market also provides supportive macroeconomic conditions. Demand continues to rise due to electrification, electric vehicle adoption, renewable energy infrastructure, and the expansion of AI-related data centres. At the same time, many industry analysts forecast structural supply deficits over the coming decade as permitting challenges and capital intensity limit the pace of new mine development. Tailings reprocessing projects such as Playa Verde offer a potentially faster route to supplying additional copper to the market.

Another notable aspect of the investment case is management's financing strategy. Rather than relying heavily on equity issuance, Halo intends to pursue a combination of offtake agreements, vendor financing, royalty and streaming transactions, and project debt. If successfully executed, this approach could reduce shareholder dilution relative to many junior mining peers.

Investors should nevertheless recognize the risks. The company remains pre-FID and must still secure financing and operating partners. Playa Verde currently represents the primary source of near-term value, creating concentration risk. Commodity price volatility, financing market conditions, and execution challenges could all affect outcomes.

Looking ahead, the most important catalysts include completion of the updated feasibility study, finalization of financing arrangements, selection of operating partners, and progress toward a final investment decision targeted for late 2026. Success on these fronts would move Halo closer to its goal of first production in 2028 and provide a clearer indication of whether the project's attractive economics can be translated into shareholder value.
