Vietnam: Process for determination of output of solid minerals actually extracted

According to Circular No. 61/2017/TT-BTNMT of the Ministry of Natural Resources and Environment of Vietnam, the output of actually extracted solid minerals shall be determined according to the following process:  

- Based on the approved mine design, 5-year mining plan and current state of the mining sites closed in the preceding year, mining organizations and individuals draw up the (estimated) mining plan for the calculation year.

- Preparing books used for recording and storing updated data and information at specific mining stages, including mining site earthworks, preparation, drilling or blasting (if required); excavation, shoveling and removal of surface materials; mineral transportation; mineral screening, sieving, separation and enrichment (if required), and data and information about crude ores storage facilities (if any).    

- Measuring, recording and updating volume and quality of each activity (with respect to any activity which may be measured and of which volume is determined directly); checking documentation and results of measurement activity for site map update, estimating volume of each activity (with respect to any activity that must be measured and of which volume is determined through current state maps or cross-sections; drawings or spreadsheets, etc.) for specific mining stages in books.

- Checking and preparing acceptance testing reports on volumes which have been recorded and measured for specific activities at each mining stage; collecting invoices, evidencing documents, accounting records and results of assessment of mineral quality (if any) for determination of actual mining output. 

- Finally, combining data and information which have been recorded and updated into statistical charts similar to sample ones hereto attached; comparing actual mining output with total actual volume (including waste aggregates and useful minerals) which is determined as of December 31 of the calculation year; making comparison with the (estimated) mining plan for any adjustment made in the succeeding year.
