- Bank Cubic Metre (BCM) Represents one cubic metre of material measured prior to disturbance.
- Clean Coal Coal that has been sized, washed and dried in preparation for shipment to customers. Washing coal removes impurities such as rock and ash.
- Coal Reserve Coal quantities that are anticipated to be mineable based upon the completion of feasibility studies, utilizing existing technology, under prevailing economic conditions and which have no legal impediment to mining.
- Coal Year The 12month period typically from April 1 to March 31 that defines the term over which coal prices are typically contracted between steel mills and metallurgical coal producers.
- Coke A hard, dry carbon substance produced by heating coal to a very high temperature in the absence of air, used primarily in the manufacture of iron and steel.
- Coking Coal A metallurgical coal that exhibits the physical and chemical properties that are necessary to form coke.
- In Situ In the ground, undisturbed (i.e. prior to blasting).
- Metallurgical Coal The various grades of coal suitable for making steel, including coking coal and PCI coal.
- Mineable Capable of being mined under current mining technology and environmental and legal restrictions, rules and regulations.
- Pulverized Coal Injection (PCI) A process in which coal is pulverized and injected into a blast furnace. Those grades of coal usedin the PCI process are generally non-coking.
- Overburden The layers of soil and rock covering a mineral deposit.
- Resource All in-situ coal tonnes meeting either underground or surface criteria specified in the applicable regulatory criteria. These tonnes can be considered as technically extractable coal independent of economic criteria.
- Run-of-mine Coal (ROM) The coal produced from the mine before it is processed.
- Strip ratio Measured by BCM per tonne of clean coal produced, the strip ratio states the volume of rock that must be moved for each metric ton of clean coal produced.
- Ton A unit of weight equivalent to 2,000 pounds or 907.2 kg. This is also known as a "short ton".
- Tonne A metric unit of weight equivalent to 1,000 kg or 2,200 pounds. This is also known as a "metric ton".
- Yield The percentage of clean coal that is produced from the raw coal processed at the wash plant.
