Jan 01, 2018 Mineral operations consist of three phases mining, processing, and refining. In single-product and single-process mode, the optimum cut-off grade and the net present value of production are calculated for each year of the mine's life.The mineral resources for the Scotia Mine Deposit have been classified as Measured, Indicated and Inferred categories based on CIM Definition Standards in accordance with NI 43-101 reporting guidelines, and are reported with respect to cut-off values calculated using the assumed processing costs and recoveries, and metal prices.

Oxidized and Transitional Mineral Resources are reported at a 0.2 g AuEq t cut-off in consideration of potential open-pit mining and heap-leach processing. Unoxidized Mineral Resources are reported at a 0.3 g AuEq t cut-off in consideration of potential open pit mining a milling agitated leaching or flotation processing.2 Mineral reserves and resources are estimated using a minimum NSR cut-off of C$105 per tonne for waste filled mining areas and a minimum of C$116 per tonne for paste filled mining areas. 3 Metal prices of $1.10 per pound zinc, $1,500 per ounce gold, $3.10 per pound copper, and $18.00 per ounce silver with an exchange rate of 1.30 C$ US$ were.

Mining, processing and administrative costs used to determine NSR cut-off values were estimated based on actual operating costs incurred from July 2019 through June 2020. Mining recovery is estimated to average 95 with average mining dilution ranging from 13 to 32 depending on the mining methodology. Mineral Resources are reported at an NSR.The Mineral Resource has been reported at a Net Smelter Return (NSR) cut-off of A$20 t. The A$20 t value represents the PFSU mill limited break -even cut -off of A$17 per ore tonne mined, plus an all-inclusive mining cost of A$2.76 per total tonne mined . The Mineral Resource estimate was further constrained within optimised.

Consequently, in relation to open- pit mining, cut-off grade can be defined as the minimum grade at which the value of the ore balances all costs on mining, waste p= Cost of mineral processing.Nalunaq hosts 2020 Inferred Resources of 251 koz in 422,770 tonnes at a grade of 18.5 g t Au 4. In addition, AEX has identified a near-mine Exploration Target of between 2.5 and 10 million tonnes at between 2.4 and 6.0 grams of gold per tonne, or between 200 thousand ounces and 2.0 million ounces of gold 4. Drilling since 2017 has increased the.

Aug 27, 2021 The NSR cut-off of US$50 tonne is based on operational mining and milling costs plus general and administrative costs. The Mineral Resource Estimate encompasses both the MNFWZ and the MNV. Drilling campaigns from 2018 have focused on the MNFWZ and no drilling has been performed on the MNV since 2017.May 26, 2021 Cut-off grade considers a gold price of C$1,914 per ounce (US$1,450 per ounce at CAD USD exchange rate of $1.32) for mine design purposes, a 97 metallurgical processing recovery for both the S50 Martin Zones and 98.5 for the Kiena Deep Zone, life of mine operating cost of C$122.92 t mining, C$28.25 t processing, C$36.53 t General and.

Acid mine drainage - Acidic run-off water from mine waste dumps and mill tailings ponds containing sulphide minerals. Also refers to ground water pumped to surface from mines. Adit - An opening driven horizontally into the side of a mountain or hill for providing access to a mineral deposit.(8) Out-of-pit Mineral Resource NSR cut-off considers ore mining, crushing, transport, processing and G A costs that respectively combine for a total of ($58 +.

Cutoff Grade Optimization Based On Maximizing Net Present

In this study, dynamic cut-off grades and multiple processing streams are used to maximize the value of a mining project based on a finite resource. Optimal cut-off policies are generated using Lane’s method for determining cut-off grade. By maximizing the present value of future profits as a function of cut-off grade, mine project.The cut-off grade takes into account Operating Mining, Processing Haulage and G A costs, excluding capital. The Mineral Reserve is depleted for all mining to September 30, 2020. Mineral Reserve tonnage and contained metal have been rounded to reflect the accuracy of the estimate, and numbers may not add due to rounding.

Dec 04, 2018 The rules define “cut-off grade” to mean the grade (i.e., the concentration of metal or mineral in rock) that determines the destination of the material during mining.For purposes of establishing “prospects of economic extraction,” the cut-off grade is the grade that distinguishes material deemed to have no economic value (it will not be mined in underground mining or if mined in.The mineral resource was estimated using a minimum cut-off grade for two combined potential extraction scenarios constrained pit and underground. Cut-off grades of 0.75 g t Au for constrained pit and 2.40 g t Au for underground were defined based on a gold price of CA$2,160 and an exchange rate of 1.34 USD CAD.

Cut-off is based on break-even economics at a Zinc price of $1.07 lb, with an assumed zinc recovery of 94 , and actual processing, and G A costs from the ESM operation. No mining costs were considered in the calculation of this COG, as the pit optimization incorporates the mining.Dec 14, 2020 The cut-off grade covers processing costs of $12.00 t, administrative (G A) costs of $1.00 t, and low-grade stockpile Rehandle costs of $1.50 t. Mining dilution of 20 at 0.10 g t is applied to the in-situ Mineral Resources. Mining Recovery of 96 of diluted tonnages is assumed. Estimates have been rounded and may result in summation differences.
