​ As of December 31, 2022 and 2021, no reevaluations of assets for exploration and assessment of mineral resources have been conducted. Mineral resource exploration and evaluation expenditure Given the nature of operations of the Company and the type of exploration it undertakes, disbursements for exploration can be found in 4 stages: Execution, economically feasible, not economically feasible and in exploitation: (a)Not economically feasible: Exploration and evaluation disbursements, once finalized and concluded to be not economically feasible, will be charged to profit and loss. As of December 31, 2022, and 2021 there were no disbursements for this concept. (b)Execution: Disbursements for exploration and evaluation under implementation and therefore prior to determination of economic feasibility, are presented as part of property, plant and equipment as constructions in progress. ​
