Halo Minerals (AIM:HALO) - EIA-Approved Chile Tailings Project Targets H2 2028 Production

Key Concepts

• ESG Metals: A strategy focused on the near-term production of strategic/battery metals by reprocessing legacy mine waste.
• Tailings Reprocessing: The extraction of valuable minerals (copper, gold) from historical mine waste deposits.
• SXEW (Solvent Extraction and Electrowinning): A hydrometallurgical process used to recover high-purity copper cathode from leach solutions.
• Flotation: A process used to separate minerals from gangue by taking advantage of differences in their hydrophobicity.
• JORC Compliant Resource: A mineral resource estimate that meets the standards of the Joint Ore Reserves Committee.
• EIA (Environmental Impact Assessment): A critical regulatory approval required for mining operations to proceed.
• FID (Final Investment Decision): The point in a project where the company commits to the capital expenditure required for construction.
• BFS (Bankable Feasibility Study): A comprehensive study used to secure project financing.

1. Company Overview and Strategy

Halo Minerals PLC is a London Stock Exchange (AIM) listed company focused on the "ESG metals" strategy. CEO Andrew Dennan emphasizes that the company’s core value proposition is the reprocessing of surface-accumulated, metal-rich legacy mine waste in Chile. By focusing on tailings rather than greenfield exploration, the company aims to:

• Avoid the environmental impact of new mining (deforestation, new land disturbance).
• Utilize existing infrastructure and local labor.
• Achieve production faster and at a lower cost than traditional primary mines.

2. Flagship Project: Playa Verde

The Playa Verde project is 100% owned by Halo Minerals. It consists of tailings deposited in a dry riverbed that migrated 120 km to the coast.

• Resource: 32 million tons of JORC-compliant reserves at 0.25% copper, containing approximately 80,000 tons of copper.
• Environmental Impact: The site is currently a toxic beach. Halo’s operation includes a remediation component: by removing heavy metals (specifically arsenic) during processing, the company intends to return the beach to the local municipality for recreational use.
• Economics: Based on a $5.30/lb copper price and $4,300/oz gold price, the project shows an NPV (10%) of $155 million and an IRR of 51%.

3. Operational Methodology

The company is moving from a Preliminary Feasibility Study (PFS) to a Bankable Feasibility Study (BFS).

• Extraction: A single-wheel floating suction dredge will recover tailings from the beach.
• Processing: A dual-process approach using SXEW for copper cathode and flotation for copper/gold concentrate.
• Optimization: The company is currently reviewing flow sheets and exploring the acquisition of used dredges or leasing options to shift capital expenditure (CAPEX) to operational expenditure (OPEX).
• Scale: The plant is designed to process 5 million tons of ore annually, producing 7,500 tons of copper cathode and 8,000–8,500 tons of concentrate (with a 5.5 g/t gold credit).

4. Regulatory and Growth Environment

• Permitting: The EIA is already approved. The company is currently pursuing "Article 17" maritime access rights to potentially access an additional 100 million tons of tailings located offshore.
• Political Climate: The Kast administration in Chile is viewed as pro-business, with proposed corporate tax reductions (27% to 23%) and a supportive stance toward mining growth.
• Partnerships: Halo is working with the Santiago-based firm Bios Mining and Engineer Mining and Infrastructure to finalize cost structures.

5. Financing Strategy

Halo Minerals is pursuing a "layered" funding stack to minimize equity dilution:

1. Pre-pay and Off-take Arrangements: Engaging with metal traders to secure upfront capital.
2. Vendor Financing: Targeting 50–60% of plant and equipment costs through supplier credit.
3. Royalty and Streaming: Utilizing gold/copper streams to provide non-dilutive capital.
4. Project Debt: Leveraging the project’s high cash flow potential ($50–60 million/year) to secure development debt.
5. Equity: Reserved as a final option to optimize the cost of capital.

6. Notable Quotes

• "We’re not in the business of wanting to particularly own a dredge and operate a dredge, we’re in the business of processing minerals." — Andrew Dennan, on the strategy of contracting out operations to reduce execution risk.
• "These are perceived as liabilities, but if they’re metal-rich, through a different lens, you can see them as metal-rich assets." — Andrew Dennan, regarding the shift in perspective toward legacy tailings.

7. Synthesis and Conclusion

Halo Minerals is positioning itself as a low-risk, high-reward player in the copper market by leveraging "ESG metals." By utilizing tried-and-tested dredging and processing technologies on a well-defined, permitted resource, the company aims to bypass the typical risks associated with greenfield mining. With a clear pathway to FID by the end of the year and a focus on non-dilutive financing, the company is strategically aligned with the global demand for copper driven by electrification and AI infrastructure. The project’s dual benefit—economic production and environmental remediation—provides a strong social license to operate in Chile.
