International standards of disclosure for mineral projects have gained increasing prominence since the late 1990s. The Committee for Mineral Reserves International Reporting Standards (CRIRSCO) was formed in 2002 with a goal to promote best practice in the international public reporting of Mineral Exploration Results, Mineral Resources and Mineral Reserves. The five founding mining jurisdictions of Australasia (JORC), Canada (CIM), Europe (PERC), South Africa (SAMREC) and USA (SME) have now been joined by eight additional countries; Brazil, Chile, Columbia, Indonesia, Kazakhstan, Mongolia, Russia and Turkey. Judging by the interest of other countries, CRIRSCO members with professional associations and Codes will soon cover most countries where mining is carried out or where financing is sought. Investors should now be able to make informed investment decisions based on transparent disclosure prepared by competent persons.
