Northwest Territories Mining Regulations — 77
Condition on removal of minerals 77 (1) Subject to subsection (2), it is prohibited to remove minerals or processed minerals produced from a mine, other than for the purposes of assay and testing to determine the existence, location, extent, quality or economic potential of a mineral deposit in the lands constituting the mining property, until the weight and any other information necessary to establish the value of those minerals or processed minerals has been ascertained and entered in the books of account referred to in subsection 76 (1). Condition on removal of precious stones (2) Precious stones must not be removed from a mine — other than in a bulk sample or in a concentrate for the purposes of establishing the grade and the value of the stones in a mineral deposit — or cut, polished, sold or transferred, until they have been valued by a mining royalty valuer. Facilities required for valuation (3) The operator of a mine must provide, in the Northwest Territories, any facilities and equipment, other than computer equipment, necessary for a mining royalty valuer to value any precious stones produced from the mine. Facilities considered part of mine (4) For the purposes of these Regulations, facilities referred to in subsection (3) are considered to be part of the mine and any transfer of the precious stones from one part of the mine to another is not considered to be a removal of the stones from the mine. Cleaning of precious stones (5) Precious stones must not be presented to the mining royalty valuer until the operator of the mine has cleaned the stones so as to remove all substances from the stones that are not part of them. Presentation of precious stones to royalty valuer (6) As soon as any precious stones have been processed into a saleable form, they must be presented to a mining royalty valuer for valuation. Separate valuation of precious stones (7) An operator who produces precious stones and sells or transfers them to persons who are related to the operator must present to a mining royalty valuer (a) all stones that are to be sold or transferred to a person related to the operator, for separate valuation before their sale or transfer; and (b) all stones that are to be cut or polished by the operator or any related party, for separate valuation before their being cut or polished. Presentation of diamonds to royalty valuer (8) For the purposes of subsections (6) and (7), unless otherwise agreed on by the operator and the mining royalty valuer, an operator must present to the mining royalty valuer (a) diamonds with a weight of 10.8 carats or more, separately, together with the weight of each diamond; (b) diamonds with a weight from 2.8 carats to 10.79 carats, in lots separated according to weight in carats, together with the number of diamonds per lot; (c) diamonds with a weight from 0.66 carats to 2.79 carats, in lots separated according to weight in grainers, from which randomly selected samples, accurately representing the composition of each lot, have been separated; and (d) diamonds with a weight of less than 0.66 carats, in lots separated according to industry standard DTC sieve sizes, from which randomly selected samples, accurately representing the composition of each lot, have been separated. Estimate of market value of diamonds (9) Before diamonds are presented to the mining royalty valuer under subsection (8), the operator must provide an estimate of the market value of each diamond or lot, as the case may be, to the Chief.
