NI 43-101 is a Canadian regulatory standard that governs the public disclosure of scientific and technical information about mineral projects. It is widely used in the mining industry, including bauxite, gold, iron ore, and diamond exploration companies listed on Canadian stock exchanges. The standard ensures that investors receive reliable, transparent, and verified information about mineral resources and reserves.
Under NI 43-101, technical reports must be prepared or reviewed by a “Qualified Person” (QP), who is a professional with relevant experience in geology, mining engineering, or related fields. The standard defines strict guidelines for reporting mineral resources, exploration results, feasibility studies, and economic assessments. It also regulates how companies communicate drilling results, sampling data, and resource estimates to prevent misleading or speculative claims. NI 43-101 plays a critical role in maintaining investor confidence and market integrity in the mining sector. Although it is a Canadian regulation, its influence extends globally because many international mining companies follow its standards to ensure credibility and access to capital markets.
