Ruling 1816

The niṣāb for mined products is fifteen common (ṣayrafī) mithqāls12 of coined gold, i.e. if the value of something that is extracted from a mine reaches fifteen common mithqāls of coined gold after deducting the costs for extracting it, then the subsequent expenses – such as the costs for purifying it – are subtracted and khums must be paid on the remainder.

12 Based on the definitions in Ruling 1912, one common mithqāl is equal to 4.608 grams; therefore, fifteen common mithqāls is equal to approximately 69.12 grams.
