  • Chapter 1.21® Amortization of Natural Resources e.g

    The amount of amortization expense recorded on Natural resources depends on # of finished units extracted or depleted. This is very similar to the units-of-production amortization method we discussed above. As an example, consider Hargrave Mines Ltd purchases a mineral deposit of 450,000 tonnes of ore available to mine. The entire deposit is purchased for $2million with a salvage value of $300,000. What amortization expense is incurred on this Mineral deposit if 120,000 tonnes of Ore
