Disclosure Standards for Companies Engaged in Mineral Exploration, Development & Production http://www.tmx.com/en/pdf/Mining_Disclosure_Stds.pdf X Use All resource and reserve estimations disclosed must provide the name of the qualified person responsible for the calculation and his/her relationship to the company. The company must also state whether, and how, any independent verification of the data has been performed. Particular care should be taken to distinguish between resources and reserves so that they are not assumed to be equivalent in the mind of the reader. Resources and reserves should, whenever possible, be published in a manner so as not to confuse the reader as to the potential of the deposit. Inferred resources must not be aggregated with measured and indicated resources nor proven and probable reserves, as the case may be. Any categories of resources and reserves which are aggregated must also be disclosed separately. When reserves are first reported, the key economic parameters of the analysis must be provided, such as operating and capital cost assumptions, and the assumed prices of the mineral commodities which could be produced. If the prices used differ from the current prices of the commodities, an explanation should be given, including the effect on the economics of the project if current prices were used. Sensitivity analyses may be used to provide a better understanding of the effects of changes in commodity prices on the economics of the project. All reported quantities of resources and reserves must be expressed in terms of tonnage and grade. Contained ounces of gold, for example, should not be disclosed out of the context of the tonnage and grade of a deposit, with the possible exception of the resources and reserves of mining companies which have more than one mine in production. In that case, the company should not aggregate contained minerals from properties that are not in production with those that are in production.
