Explanatory Notes on Main Statistical Indicators

Newly Discovered Mineral Prospect-denotes a mineral occurrence of commercial value or value for further work, which has been recently found on the basis of the information obtained by regional geological survey, mineral reconnaissance, geophysical and geochemical anomalies, and mineral potentials, or found on the basis of known mineral occurrences (including previously negated ones) and clues furnished by the local people engaged in mining and through preliminary work during the reporting period. The main requirements are as follows: ① the distribution and burial conditions of orebodies have been revealed and controlled by some geological survey and necessary engineering work; ② ore has been regularly sampled and analyzed and the ore grade meets current requirements for commercial exploitation and utilization of ore; ③ the amount of mineral resources in a prospect should reach 1/2 of the upper limit of a small size in the “Criteria for the Size Classification of Mineral

Resources and Reserves”; ④ the categories of mineral resources/reserves are mainly assigned to controlled resources (332), inferred resources (333) and predicted resources (3341); and ⑤ relevant data such as geological plan maps, sections, engineering documents, sampling location maps and brief explanatory notes should be submitted.

Reserves-refer to that part of the reserve base which could be economically extracted or produced. After studies of economic, mining, beneficiation and smelting, environmental, legal, market,social and governmental factors and consequential revision, it is indicated that that part of the reserve base is economically extractable or has been extracted at the time of prefeasibility study, feasibility study or formulation of an annual extraction plan. According to the degree of geological reliability and stages of the feasibility evaluation, reserves may be divided into extractable reserves and pre-extractable reserves.

The reserve base is expressed by a quantity from which the design loss and mining loss are not deducted. According to the degree of geological reliability and stages of the feasibility evaluation, the reserve base may be divided into the demonstrated economic reserve base,controlled economic reserve base, demonstrated marginally economic reserve base and controlled marginally economic reserve base.

Resources-refer to that part of identified mineral resources and potential mineral resources,including those considered submarginally economic through the feasibility study or prefeasibility study and those considered potentially economic through exploration but without a feasibility study or pre-feasibility study, as well as predicted mineral resources through regional reconnaissance.
