This Report covers the Investment Highlights, Conclusion, and Recommendation on the stock.

Key Recommendation Rationale – Sell at GBX 4,030.00

• High Dependence on Copper Prices - The company’s earnings are heavily concentrated in copper, making it highly vulnerable to cyclical demand fluctuations, particularly from China and global industrial activity.
• Rising Cost Pressures - Increasing input costs, including energy, water, and labour in Chile, are compressing margins and reducing operational efficiency, especially in lower-grade ore environments.
• Execution and Capex Risks - Ongoing and planned expansion projects carry execution risks, potential delays, and cost overruns, which could impact returns and cash flow generation.

Conclusion

ANTO is expected to trade at a discount, considering highly dependent on copper prices, global economic slowdown and demand uncertainty. For conducting the valuation, the following peers have been considered – BHP Group (LSE: BHP), Atalaya Mining copper PLC (LSE: ATYM) and others.

Given its current trading levels, increasing cost pressures in Chile, ongoing capital expenditure programmes, commodity volatility, valuation risk, recent rally in the share price, and associated risks, it is prudent to exit the stock at the current levels. Hence, a ‘Sell’ recommendation is given on the stock at the current market price of GBX 4,030.00 on 08^th April 2026 at 08:25 AM GMT+1.
