AbstractThis report discusses definitions, concepts and parameters used to determine coal resource and reserve quantities, and provides a framework to facilitate consistent categorization of coal quantities found within various depositional and tectonic regimes in Canada. Coal deposits, or portions thereof, are first categorized in terms of their geological complexity (Geology Type), and probable recovery method (Deposit Type). Methods for determining quantification parameters including seam thickness, areal extent and bulk density are outlined for each geology/deposit category. Within each geology/deposit category, coal resources are further divided, based on their assurance of existence, into measured, indicated, inferred and speculative subdivisions and, according to their feasibility of exploitation, into immediate and future interest subdivisions. Coal reserves within each geology/deposit category are subdivided according to whether they are within or outside active mining areas, and may be reported on in place, recoverable and saleable bases. A wide cross-section of the coal industry in Canada contributed to the development of this reporting system. To ensure that the parameters and concepts expressed in the system continue to reflect technological and economic realities in the future, the Coal Association of Canada has established a committee to facilitate periodic reviews.
