Germanium and Gallium Mines

 Germanium and Gallium Mines

Individual assignment

Canada World Mining Inc. (CWMI) is evaluating to invest either in a new Germanium or Gallium mine.  CWMI’s geologist has just finished his analysis of the mine site.  He has estimated that both mines would be productive for 8-9 years, after which the Germanium or Gallium would be completely mined.

John Walker, CEO, has requested Mary Rose, CFO, to perform an analysis of both new mines and present her recommendations on whether the company should invest in either the Germanium mine or the Gallium mine.

Mary has used the estimates provided by John to determine the revenues that could be expected from the mines.  She has also projected the expense of opening the mines and the annual operating expenses.  The expected cash flows each year from the mine are shown in the table above.  CWMI has a 12% required return on all projects.
