- Mineral Resource Estimate
- A quantified inventory of mineralized material β classified as inferred, indicated, or measured β based on geological sampling and modeling.
- Mineral Reserve
- The economically mineable portion of a measured or indicated resource, accounting for mining, processing, and economic parameters.
- Capex (Capital Expenditure)
- One-time upfront costs to build or acquire mine infrastructure β including earthworks, processing plant, tailings facility, and access roads.
- Opex (Operating Expenditure)
- Ongoing per-unit costs to mine, process, and sell the commodity β typically expressed as cost per tonne mined or cost per ounce produced.
- Strip Ratio
- In open-pit mining, the volume of waste rock that must be moved to expose one unit of ore β a key driver of opex and mine life economics.
- Metallurgical Recovery
- The percentage of target metal or mineral extracted from the ore during processing β a critical efficiency metric directly affecting revenue.
- Tailings
- The slurried waste material remaining after ore processing, requiring engineered containment and long-term environmental management.
- Net Smelter Return (NSR)
- Revenue received by the mine operator after deducting smelting, refining, and transportation charges from gross metal sales.
- Reclamation Bond
- Financial assurance β cash, surety bond, or letter of credit β posted with regulators to guarantee site rehabilitation upon mine closure.
- NI 43-101 / JORC
- Canadian (NI 43-101) and Australian/international (JORC) standards governing public disclosure of mineral resource and reserve estimates.
- Life of Mine (LOM)
- The projected operational lifespan of the mine from first production to final extraction, based on the proven and probable reserve estimate.
- AISC (All-In Sustaining Cost)
- A gold-industry cost metric that includes opex, sustaining capex, royalties, and corporate overhead β enabling apples-to-apples cost comparison across mines.
