ABH offers NI 43-101 reporting services to standards of excellence across the industry.

Our team has Qualified Persons in geology, mining, and processing, giving us accreditation to complete all sections of an NI 43-101 report at any stage of development.


National Instrument 43-101 (abbreviated as NI 43-101) is a Canadian Mineral Resource Classification system used to guide the disclosure of information related to mineral properties. Any company, foreign or domestic that lists on stock exchanges (TSX, TSXV, NEO, CSE) overseen by the Canadian Securities Administration (CSA) are required to abide by the NI 43-101 rules and guidelines for distributing information related to mineral properties. These rules and guidelines apply to all mineral resource properties including, but not limited to gold, silver, copper, diamond, rare earth elements (REEs), and bulk elements like gypsum, graphite, quartz, salt, etc.

  • NI 43-101 prescribes when, and in what format, technical reports must be filed - as well as whether or not the Qualified Persons (QPs) must be independent of the company and property.

  • Form 43-101F1 prescribes how technical reports must be prepared and what they must include.

These reports can take many forms and the NI 43-101 guidelines apply to any report that will be issued publicly or referred to publicly such as in a press release.


Typical reports are:

  • A first-time exploration or operating report on a mineral property

  • A summary of the exploration activities with Quality Control/Quality Assurance (QA/QC) on a property

  • A report of the Mineral Resource Estimate (MRE) for a property

  • A report containing the results of a Preliminary Economic Assessment (PEA), Pre-feasibility Study (PFS), Feasibility Study (FS); depending on the complexity of the project

  • A summary of the updated resource and reserve estimates and the work conducted on an operating project

The NI 43-101 requirements don't apply to just formal reports but also to any discussion of a mineral property including drill results, summaries of reports, or any other pertinent data on a mineral property.

The goal is to ensure proper disclosure:

  • Requires that public reporting of technical information is:

  • Signed off by a professional who takes responsibility for the information

  • Clear, balanced, and not misleading - transparency is key

  • Understandable to a reasonably informed investor

  • Consistent in its use of standardized terms and definitions

  • Based on reasonable assumptions which are clearly explained

  • Unbiased and identifies the potential risks and uncertainties
