Building a new refinery

The construction and installation of a new refinery will cost $22 million. In addition, a processing plant will also need to be constructed at a cost $6 million. This plant will need to be supplied with grinding machines, DMS flotation machines and other equipment at a total cost of $16 million. Kidman Resources' current fleet of Haul trucks, water carts and dump trucks will meet the needs for this project, however until recently, the fleet has been earning a rental income of $120,000 per year.

Under the agreement with Tesla inc., the lithium mined is expected to generate a revenue of $15 million per year, which will increase by 2.8% per annum adjusted for rising costs. Due to the additional complexities involved with the construction and management of this new refinery, 5 new engineers (yearly salary per engineer $160,000) will replace 5 existing engineers (yearly salary per engineer $120,000). All other remaining labour force required is expected to cost $3 million per annum for the duration of the project.

For tax reasons you will expense the cost of the processing plant immediately. The cost for the construction and installation of the new refinery and associated machines and equipment will be depreciated over three years using the straight-line method. Due to the nature of the mining project, the machines and equipment will likely have a salvage value of $10 million at the end of three years. Finally, the required net working capital is $2 million.
