Golden Miners purchased a mine in 2013 for $960,000. It was estimated that the mine contained 3,000,000 tonnes of ore, and would be totally worthless once all ore was extracted. Golden Miners extracted 250,000 tonnes in 2013 and 300,000 tonnes in 2014. Refer to Table 10-4. Assuming 500,000 tonnes are extracted in 2015, the book value of the mine on January 1, 2016, would be: O A. $624,000. O B. $160,000. O C. $336,000. O D. $800,000.
