dc.description	Estimating Mercury Use and Documenting Practices in Artisanal and Small-scale Gold Mining (ASGM) - Methods and Tools. This document is a technical annex presenting equations and example calculations used to estimate gold production and associated mercury flows in artisanal and small-scale gold mining contexts. It outlines formulae for correcting impure gold to a 100 percent equivalent, computing gold yield from ore based on recoverable ore grade, and calculating throughput rates of processing units such as sluices. The text describes how to apply these equations to derive daily and annual statistics for gold production, mercury loss, number of active processors and miners at site, regional, and national levels.	en
