Gold Mine

MyBank, a major financial institution managing a portfolio with 10% annual returns, has the opportunity to purchase an untapped gold mine in Peru from the Peruvian government for $250M. You must determine whether this investment deserves a place in MyBank's portfolio.

Client: MyBank Industry: Financial Services / Commodities Investment Geography: Peru (mine operations); Global (gold markets) Portfolio Benchmark: 10% annual return The Peruvian government seized a mineral-rich gold mine a decade ago and now wants to sell it to raise cash. The mine has not been developed since seizure. MyBank must evaluate whether acquiring it creates value beyond the 10% benchmark.

Assess whether the Peruvian gold mine is a sound investment for MyBank's portfolio relative to its 10% annual return benchmark, and identify conditions and risks that could affect the investment thesis.

Q1 – Investment Worthiness Framework Assess across three dimensions: • Financial: Must exceed 10% annual ROI. Analyze setup costs, variable mining costs, gold production volumes, market price, mine longevity • Market: Gold market dynamics, price volatility, portfolio fit, alternative investment opportunities • Logistical: Mine operations (outsourced or in-house?), export infrastructure, labor pipeline, ethical considerations Q2 – Financial Analysis Using conservative gold price of $1,200/oz: • Margin per ounce: $1,200 − $200 = $1,000 • Annual gross profit: 150,000 oz × $1,000 = $150M • Annual net profit (after fixed costs): $150M − $25M = $125M • Payback period: $300M ÷ $125M ≈ 2.4 years (full return by year 3 of operations / year 4 overall) • 5-year total profit: $125M × 5 = $625M vs. $300M invested — well above the $450–480M at 10% annual returns Conclusion: This investment significantly outperforms the portfolio benchmark, even at conservative gold prices. Q3 – Key Risks • Political/Regulatory Risk: Peru seized this mine before — could do so again; export policy uncertainty • Gold Price Risk: A 50% drop in gold prices would eliminate profitability at current cost structure • Brand Risk: Is MyBank exploiting a cash-strapped government in a way that invites reputational harm? • Natural Disaster: El Niño or geological risk could disrupt or destroy operations • Labor: Local qualified workforce availability; wage expectations; talent pipeline sustainability • Infrastructure: Ability to transport gold from Peru to export markets Q4 – Political Risk Mitigation: Expected Value Analysis Three years in, a newly elected Peruvian president creates 50% seizure risk. Two mitigation options over a 5-year horizon (assumes $0 profit after seizure): • Base Case: ($125M × 5) × 0.5 = $312.5M expected value • Option 1 – Raise wages by $25M/yr: 5 × ($125M − $25M) × 0.7 = $350M — higher than base case • Option 2 – Sell 40% stake for $100M: (5 × $125M × 0.6) × 0.9 + $100M = $437.5M — highest expected value Recommendation: Option 2 (local partnership) dominates on a 5-year horizon. However, qualitative factors matter: • Long-term: Selling 40% permanently reduces ownership — does this make sense beyond 5 years? • Ethics: Does the $100M stake sale amount to a bribe to local interests? • Other options: Full liquidation (~$500M), direct government negotiations, or hybrid approaches
