Abstract:
Introduced in Canada in 2001 by the Canadian Securities Administrators in response to the Bre-X scandal, National Instrument 43-101 (NI 43-101) was designed to enhance transparency and reliability in mining project disclosures. Since its inception, it has played a key role in strengthening investor and public trust in mining projects both within Canada and globally. Over the years, the structure of NI 43-101 reports has evolved to improve clarity and comprehensiveness, incorporating chapters on mining and recovery methods, marketing, environmental studies, and infrastructure.
Despite these improvements, the report format still falls short in addressing certain critical aspects of mining projects while providing excessive detail in others.
Adding new stand-alone chapters on waste management, geotechnical considerations, and mine closure would enable qualified persons (QPs) to adequately address these essential topics. These areas are fundamental to every mining project and carry significant economic and safety implications, as evidenced by several recent high-profile tailings dam and heap leach failures in Canada, Brazil, and Turkey.
Conversely, the geology-related sections, while valuable for understanding the resource model, could be streamlined into fewer sections to improve clarity and efficiency. In our opinion the current order of sections also needs to be reorganized.
