Our client is an Australian mining company, whose main product is Iron Ore, which it sells exclusively to China. This company is the largest producer in volume in this market with 230 million tons sold each year. It is also the lowest cost producer at 27$ per ton of production costs. We estimate the total Chinese demand for Iron Ore today to be around 980 million tons per year. Our client has won a concession to mine a new site adjacent to its biggest mine, and increases production to 360 million tons per year (i.e. 130 million additional tons per year). Is this worth doing?

Clarifying Information

  1. Board typically approves projects with payback in less than 5 years. You can use payback with no discounting for your math.
  2. Consider that the market will remain flat at 980 million tons per year for the foreseeable future
  3. $ 3 Billion upfront
  4. Consider this new mine to have the same exact cost as its current production (27$/ton)
  5. Show Exhibit A of China’s Cash - Cost curve for iron ore.
  6. For the purposes of this case, let’s limit analysis to iron ore and China.

This case asks whether an Australian iron ore mining company should expand production in the Chinese market. The analysis involves calculating the impact of increased supply on the market price, assessing the project’s payback period, and evaluating potential competitor reactions using a payoff matrix to determine the optimal strategy.

Key Insights:

  1. Commodity prices are determined by the intersection of aggregate supply (cash-cost curve) and demand.
  2. Increasing supply in a commodity market will typically lower the equilibrium price, impacting all producers.
  3. Payback period is a common metric for quick project evaluation, especially when a hurdle rate is given.
  4. Competitive strategy must account for competitor reactions; game theory (payoff matrix) can model these interactions.
  5. Being the lowest-cost producer provides a significant advantage when market prices decline due to increased supply.
