A company pays $760,000 cash to acquire an iron mine on January 1. At that same time, it incurs additional costs of $60,000 cash to access the mine, which is estimated to hold 100,000 tons of iron. The estimated value of the land after the iron is removed is $20,000. (If no entry is required for a transaction/event, select "No journal entry required" in the first account field.) 1.
