Session 3 - Geological data and information disclosure

The importance of data quality for resource estimation

This paper presents the main observations and recommendations from SRK experts based on participation in 7 projects (6 of them in Kazakhstan). Only few companies carry out exploration in accordance with international requirements (JORC, etc.), which creates troubles to attract foreign investors and to enter to the international capital market. The presentation contains an example of exploration program and QA/QC protocol including drill hole survey control, down hole survey control, random insertion of control samples (standards, blanks, duplicates), confirmation of past exploration results and verification of electronic database.
