According to the International Accounting Standard 16 Property, Plant & Equipment, if the useful life of the asset is more than one year then it must be capitalized. Furthermore, the standard also states that the expenditures like Filing fee and Licenses and Geological surveys that are required to bring the asset into working condition must be capitalized as part of Non-current Asset.
(a) Purchase of the minerals
Dr Minerals Right $598,100 (Increase in Non current asset)
