A NET SMELTER ROYALTY
HR2262's royalty is net smelter, not gross. The use of the phrase "gross income from mining" has caused some to think that the HR2262 royalty is a gross proceeds royalty. It is not. It is a net smelter royalty – although there is no such thing as a "standard" net smelter royalty. 2 A net smelter royalty allows for the deduction of
What miners need to know about smelter charges
Typically, 85-98% of the value of the contained metals are paid for by the smelter, bringing down the value received by the miner. Assessments for excess deleterious elements can also lower the returned value. If the metals recovered require further purification, a refining charge will also be assessed in dollars per unit of metal …
Calculation of the Net Smelter Return (NSR) of a Mine
These quotations are supplied by the price lists of the weekly "Metal Bulletin" or the "Engineering and Mining Journal". Generally these prices are quoted in "units", with 1 unit (1 u) being 1% of the metal in the concentrate (see Chap. 1.1.4.6). From this the net smelter return of the mine can easily be derived.

Mining 101: Net smelter returns (a measure of economic …
The net smelter return plays a pivotal role in mine planning and ore scheduling. Decisions on which parts of a deposit to mine first, the method of extraction, and the pace at which mining progresses are influenced by the NSR value of different parts of the ore body. High-NSR ore might be targeted early in the mine life to improve the …

Metal price assumptions (in US$) used to calculate the NSR for all deposits are: $3.75/lb Cu, US$22.00/oz Ag, US$1.35/lb Zn and US$1.00/lb Pb. An exchange rate of MX$20 per …
Cut-off Grades for Mineral Resource Reporting
While underground mines may operate with more than one cut-off grade, they typically have a base case or break-even cut-off. In a polymetallic mine, the cut-off may be expressed as an 'equivalent grade' of the primary metal, or by the net smelter return (NSR) value of the mineralized material.

Net Smelter Return (NSR): A Comprehensive Dive
Net Smelter Return (NSR) is a royalty mechanism predominantly used in the mining sector. Simply put, NSR represents the gross revenue that a producer (typically a mining company) receives from the sale of the mined metal, minus the costs associated with transporting and refining (or "smelting") that metal.
