This content has been specifically regulated in Circular 01/2016/TT-BTNMT issued by the Ministry of Natural Resources and Environment on January 13, 2016.

Circular 01 stipulates that when conducting the work of volume calculation, the following requirements must be ensured:

- Volume is calculated based on volume calculation criteria corresponding to the field of use and is specifically regulated in the Exploration Proposal.- Preliminary determination of the mining boundary, slope angle of the layer, slope angle of the final pit wall, stripping ratio, and the volume of stripped soil must be made.- The volume calculation method must be chosen appropriately according to the characteristics of the mineral body to ensure reliability.- Volume is calculated in cubic meters (m³).

Additionally, Circular 01 also stipulates the content and format for presenting documents in the exploration reports on riverbed sand, gravel, and soil and rock used as leveling material, which will be implemented according to the regulations on procedures, appraisal, review, and approval of mineral reserves in mineral exploration reports.
