African Gold Mines Co. (AGM) is a junior gold producer with one open-pit mine currently in production in Cameroon. The mine was established 10 years ago, and forecasts predict at least another 10 years of consistent gold production. Last year, AGM produced 250k oz of gold from their mine. They have come to us as their profit level has been slowly decreasing over the past five years. They had numerous operational issues with the mining equipment, problems with the workers’ union and issues with community relations notably. They want us to investigate what is the best course of action for their operation to return to their previous level of profitability within 12 to 24 months. They want us to specifically focus our attention to the mining department of the company.

AGM, a junior gold miner in Cameroon, faces declining profitability despite stable revenues. The company needs to reduce mining department costs by $6m annually by identifying and addressing key operational cost drivers, particularly through evaluating truck fleet replacement options.

Key Insights:

  1. Revenue remains stable despite price and production fluctuations—focus must be on cost control rather than revenue growth
  2. Maintenance (30%) and fuel (27%) are the two largest cost components and primary profitability drivers
  3. The new Caterpillar 777E and Caterpillar 780D Autonomous options achieve the same total cost ($800k vs $1210k = $410k savings per truck), requiring qualitative analysis of non-financial factors
  4. Implementation risks include technology adoption challenges, supply chain disruption, employee training requirements, and community relations impacts—particularly relevant in a remote African setting
  5. The case structure requires candidates to move from high-level analysis to specific operational decisions, incorporating both quantitative financial analysis and qualitative risk assessment
