4、ORATION AND MINE-CLOSING3.1The geological exploration report describes the spatial distribution, quality and quantity of the mineral resource/reserve; Discussesits the quality control and degree of confidence; and estimates its economic significance using text and graphical data. The geological expl
5、oration report can be used as the foundation for mine construction plans or further exploration. It can also be used as the foundation for examining and commentingon the mineral resource and reserves.3.3The report mentioned above is also regarded as essential data for the government to manage the mi
6、neral resource as well as for research and teaching. 4THE BASIC RULES FOR THE PREPARATION OF GEOLOGICAL REPORTS OF MINERAL EXPLORATION 4.1The mineral exploration is divided into four stages as follows: pre-exploration, reconnaissanceexploration, detailed prospecting andAdvanced exploration. A corres
7、ponding geological exploration report must be completed at the end of each stage. Exploration investors evaluate these reports at each sage and decidewhether or not to continue the program. However if a report is not produced at the end of each stage, a detailed report based on overall exploration d
8、ata must be compiled at the end of the exploration project. For the non-working (Renunciative) exploration block within the exploration lease, the report must be based on previously obtained exploration data. A Geological exploration report based on the obtained data must be compiled even if geologi
9、cal exploration was stopped due to cancellation. 4.2The geological exploration report must objectively, factually and accurately reflect all of the data and results of the exploration activities. 4.3The geological exploration must be combined with feasibility evaluation, and the geological explorati
10、on report must include geological exploration and feasibility evaluation. Feasibility study can be divided into three stages as follows: elementary study, pre-feasibility study and feasibility study. Elementary study is directly compiled into report by the exploration team. As far as the pre-feasibi
11、lity study and feasibility study were concerned, the geological exploration report must quote the key conclusions from the pre-feasibility and feasibility study reports. 4.4It is required that the geological exploration report be pertinent, practical and scientific. Accurate original data and reason
12、able conclusions areessential to a good geological exploration report. The geological exploration report with charts and tables must be digitized. Computer technology must be used in the evaluation of resource/reserve. It is recommended that computer technology be used to prepare the geological expl
13、oration report.4.5Each stage of the geological exploration program must be conducted according to the requirements of government regulations/specifications. Exploration data must be obtained for each stage. Theoutline of geological reports attached to this document is suitable only for the detailed
14、exploration stage. For other stages of the exploration project, the exploration report can be adjusted as required but all of obtained data must be reported. 5 REQUIREMENTS FOR THE COMPILATION OF GEOLOGICAL MINERAL EXPLORATION REPORTS 5.1 The quality of the work and data must be checked and accepted
15、 by the exploration investor or by senior company management before the end of geological fieldwork. Any significant problems discovered must be resolved before the completion of geological exploration reports. The preparation of the geological exploration reports cannotcommence before the fieldwork
16、 is checked and accepted.5.2Before the completion of the geological exploration reports, the chief editor must prepare an abstract based on appendix A of this document. The chief editor must consider the mineral property, exploration work facts and the requirement from the exploration investors. Any
17、 change of the finalized and accepted abstract must get the permission of the exploration investor first. 5.3The chief editor oversees the preparation of the geological exploration report; make the working plan; as well as checking and resolving possible problems to make sure the report can be finis
18、hed on time. A regular quality-control program must be instituted.5.4The geological exploration report must contain text, attached tables and appendices. According to the requirements for the business confidentiality or the requirements of data management of government, the mining leassee can divide
19、 the reports into different volumes. 5.5The title of the geological exploration report is standardized as follows: Province (City or Municipality) County(City, Banner, Orefield or Coalfield)Ore district(Ore block, borefield)(Mineral type) Deposit(exploration stage)Report. The accompanying map, map f
20、ormat, map scale etc. will be adopted according to related standard.5.6Original data obtained during exploration must be pigeonholed according to related technical standards. According to the governmental specification for reserve examination and estimation of mineral resource, the geological explor
21、ation report will be submitted for formal examination and comment after preliminary examination. The chief editor must revise the geological reports based on the suggestion arising from the examination and comment report. The copies of approved report must be submitted to the appropriate department
22、in accordance with related specification for geological data management. 5.7The examination and comment report must be attached to the geological exploration reports.Appendix A (Standard appendices)The outline of geological exploration reports for mineral explorationA.1 IntroductionA.1.1Exploration
