Public Reporting of Exploration Results, Mineral Resources and Mineral Reserves by Minerals Companies An introduction to the CRIRSCO family of reporting codes with special focus on The PERC Reporting Standard 2021

Module 4: Understanding the Modifying Factors and how to assess and report on “Reasonable Prospects for Eventual Economic Extraction"
Thursday 22 February, 16.00 GMT

Course Objectives

This series of courses is intended as a general overview and refresher course for professionals who are practising, or who aspire to practice, as Competent Persons (or who provide support to Competent Persons) for the purposes of Mineral Reporting. It would also be suitable for those with a more general interest in international reporting on mineral assets, including people involved in management of mining companies and consultancies, financial advisors and investors.

Since the late 1980s, public reporting of Exploration Results, Mineral Resources and Mineral Reserves has been governed by a variety of different reporting codes and standards, including: the PERC Reporting Standard (Europe), JORC Code (Australasia); NI 43 101 legislation and CIM Definition Standards and best practice guidelines (Canada), SAMREC (South Africa), SEC Industry Guide 7 (US) and others. Since 1994, under the auspices of CRIRSCO (Committee for Mineral Reserves International Reporting Standards) there has been considerable cooperation between the main bodies involved in the development of the different codes and standards and a move towards standardisation of the definitions of key terms. This course provides an introduction to the principles underlying the reporting codes and standards with particular reference to the PERC Reporting Standard 2021. The main focus of the course is on the role and responsibilities of the Competent Person when preparing assessments and reports in compliance with the PERC Reporting Standard 2021. Reference will be made to the use of the NI 43-101 Form F1 table of contents and Table 1 checklist in the PERC Reporting Standard as a framework for preparing technical reports (The JORC Code also contains a Table 1 checklist with similar content to the one in the PERC Reporting Standard).
