The Industry Specific Metrics: The World Gold Council introduced all-in sustaining costs (AISC) and all-in costs (AIC) metrics to establish comparable metrics on a cost per ounce basis.
NAV, P/NAV: Allows comparison and evaluation of a given company’s value.
Mineral Resource: It is a concentration or occurrence of natural, solid, inorganic, or fossilized organic material in or on the Earth’s crust in such form and quantity and of such a grade or quality that it has reasonable prospects for economic extraction. The location, quantity, grade, geological characteristics, and continuity of a Mineral Resource are known, estimated, or interpreted from specific geological evidence and knowledge.
Measured Resource: These are resources from which the quantity is computed from dimensions revealed in outcrops, trenches, workings, or drill holes; grade and/or quality are computed from the results of detailed sampling. The sites for inspection, sampling, and measurement are spaced so closely and the geologic character is so well defined that size, shape, depth, and mineral content of the resource are well established.
Indicated Resource: Resources from which the quantity and grade and/or quality are computed from information similar to that used for measured resources, but the sites for inspection, sampling, and measurement are farther apart or are otherwise less adequately spaced. The degree of assurance, although lower than that for measured resources, is high enough to assume continuity between points of observation.
Inferred Resource: Resources from which estimates are based on an assumed continuity beyond measured and/or indicated resources, for which there is geologic evidence. Inferred resources may or may not be supported by samples or measurements.
Resource Confidence Level: Inferred < Indicated < Measured
Reserve: A Mineral Reserve is the economically mineable part of a Measured or Indicated Mineral Resource demonstrated by at least a Preliminary Feasibility Study. This Study must include adequate information on mining, processing, metallurgical, economic, and other relevant factors that demonstrate, at the time of reporting, that economic extraction can be justified. A Mineral Reserve includes diluting materials and allowances for losses that may occur when the material is mined. Measured Resources, if economic, convert to Proven Reserves. Indicated Resources, if economic, convert to Probable Reserves. Inferred Resources cannot be converted to Reserves until they are first converted to either Measured or Indicated.
Grade: The grade of ore refers to the concentration of the desired mineral it contains, commonly quoted in grams/metric tonne, or percentage concentration. Ceteris paribus, higher grade is better.
EV/Resource Oz, EV/Reserve Oz: What you’re paying for metals in the ground.
EV/CF, EV/FCF: Measures of profitability for mining companies.
Open Pit: Open-pit mining, also known as opencast mining, is a surface mining technique that extracts minerals from an open pit in the ground. Open-pit mining is the most common method and does not require extractive methods or tunnels. This surface mining technique is used when mineral or ore deposits are found relatively close to the surface of the earth. Open-pits are sometimes called ‘quarries’ when they produce building materials and dimension stone. The grade required for open-pit mining is considerably lower than the grade required for underground mining.
Underground: Underground mining is used to extract ore from below the surface of the earth safely, economically and with as little waste as possible. The entry from the surface is through a horizontal or vertical tunnel, known as an adit, shaft or decline. Underground mining is practical when the ore body is too deep to mine profitably by open pit, when the grades or quality of the orebody are high enough to cover costs, and when the footprint of an open-pit mine is too expansive in a particular jurisdiction to get permitted.
Throughput: The amount of ore processed by a mill/plant or heap leach pad. The mill/plant/heap leach pad has a nameplate capacity (rate at which mill/plant/heap leach pad was designed to process ore).
PEA (Preliminary Economic Assessment): A PEA tries to answer the question, “How can we exploit a deposit to maximize its economic returns?” Unlike more advanced studies, a PEA can use inferred resources for its operational and financial modeling so long as one has a reasonable expectation the outcome will be a profitable mine. A PEA is normally followed by a PFS and an FS. A PEA rarely forms the basis for a production decision because of the unknown risks, costs, and timelines.
PFS (Prefeasibility Study): A PFS is a more advanced study that uses only reserves and measured and indicated resources and involves more detailed engineering in order to optimize the alternatives for developing the mine and processing the ore. It also uses tighter estimates of capital and operating costs and other economic parameters by comparing them to recent examples. A PFS is usually followed by a FS, but if financing with equity, can sometimes be used as the basis for a production decision if the economics are particularly robust or the costing is at a FS level.
FS (Feasibility Study): An FS is the most advanced study. It typically only uses reserves and involves definitive engineering and detailed costing based on actual bids where possible instead of estimates. An FS is considered essential in order to finance larger, more complex, capital intensive, lower return mining projects, or if financing with banks, in which case it is often called a “bankable”.
Mining companies have a life cycle as they develop from a claim to a producer. Analyzing each part of the life cycle requires different methods as the value of the company (hopefully) increase.
Proof of Concept: The exploration company makes a discovery, drills, needs access to capital, delineates their initial resource and conducts a PEA. See Talisker Resources.
Development: Moving into developing the asset, the company must receive permits, conduct a feasibility study, and line up project funding. See MAG Silver.
Production: The company constructs and then operates the mine, operationally optimizes it, makes positive ROIC decisions (hopefully), and lays out an effective strategy. See B2 Gold.
Depletion: The company processes its stockpiles, its mine-life expansion becomes limited, and it begins a closure plan.
