NI 43-101 (National Instrument 43-101) is the Canadian Securities Administrators' disclosure standard for technical reports on mineral projects. Any TSX or TSXV listed mining issuer must file NI 43-101 compliant reports for material projects. The standard governs how resources, reserves, capex, and project economics are calculated, reported, and signed off by a Qualified Person (QP).
What It Covers
NI 43-101 specifies content and format for technical reports — geology, exploration, drilling, sampling, QA/QC, mineral resources, reserves, mining methods, recovery, infrastructure, environment, capital and operating costs, economic analysis, and conclusions. Each section has detailed disclosure requirements.
Qualified Person (QP)
Every NI 43-101 report is signed by one or more QPs — registered engineers or geoscientists with relevant experience. The QP takes legal responsibility for the report's conclusions. For process engineering and recovery sections, this is typically a senior metallurgist or process engineer at a firm like KCA.
Why It Matters Globally
Even non-Canadian projects often use NI 43-101 format because it is widely recognized by international lenders and rating agencies as a rigorous, transparent disclosure standard. KCA studies for TSX/TSXV-listed clients are produced in NI 43-101-compatible format by default.
Related Standards
JORC (Australia/UK), SAMREC (South Africa), PERC (European), and CRIRSCO (international umbrella) are equivalent standards. Most reports across these standards translate between formats with modest effort. KCA engineers are familiar with all.
