The net book value for Nichols Ranch includes the value ascribed to the processing plant and equipment. The mineral properties acquired as part of the acquisition of Uranerz Energy Corporation ("Uranerz") in 2015 are recorded as mineral properties, as the Company does not have proven and probable reserves under SEC Industry Guide 7. Accordingly, all subsequent expenditures at the Nichols Ranch plant and equipment, which do not have any alternative use, and expenditures on mineral properties are expensed as incurred.

For the three months ended March 31, 2016, the Company recorded $1.10 million ( 2015 —Nil) of depreciation expense related to Nichols Ranch, which is included in the costs and expenses applicable to revenue in the Statement of the operations and comprehensive income for the three months ended March 31, 2016.
