Overview of the JORC Code

The Joint Ore Reserves Committee (JORC) Code is a professional code of practice that sets minimum standards for the public reporting of minerals exploration results, mineral resources, and ore reserves. It was established in 1989 and is managed by the Joint Ore Reserves Committee of the Australasian Institute of Mining and Metallurgy, Australian Institute of Geoscientists, and Minerals Council of Australia (JORC).

The primary goal of the JORC Code is to ensure that information about a company’s mineral resources and reserves is presented accurately and unambiguously to stakeholders. It is designed to give everyone involved in the mining industry or investing in it, from shareholders to analysts, access to the same quality and quantity of information.

Three principles are central to the JORC Code, often referred to as the “JORC Principles”: Transparency, Materiality, and Competence.

  1. Transparency: The information provided should be clear, concise, and effective in conveying the conclusions drawn from the data. Any assumptions, methods, or findings that might influence a stakeholder’s understanding of the report must be disclosed.
  2. Materiality: The information included in the report should be of sufficient importance to influence decision-making. Any information that could influence an investor’s decision to invest should be disclosed.
  3. Competence: The people responsible for preparing the report should have adequate knowledge and experience in the relevant fields. The JORC Code requires that a ‘Competent Person’ oversees the production of the report.

Understanding the JORC Code and its principles is crucial for anyone involved in mineral exploration and mining, as they form the bedrock of ethical and responsible reporting in the industry.

JORC Code – Key Requirements

The JORC Code establishes a set of comprehensive guidelines to govern the reporting of exploration results, mineral resources, and ore reserves. The code is designed to ensure that these reports are presented in a manner that is both informative and transparent, promoting confidence among investors and stakeholders. Below are some of the key requirements:

  1. Competent Person: One of the core stipulations of the JORC Code is the requirement for a ‘Competent Person’ to oversee the preparation and release of public reports relating to a company’s exploration results, mineral resources, and ore reserves. The Competent Person must have a minimum of five years’ experience working with the type of mineral or deposit under consideration. This requirement ensures that the person overseeing the report is suitably qualified and experienced to understand and effectively communicate the complexities and uncertainties that can be associated with mineral resources and reserves.
  2. Classification of Resources and Reserves: The JORC Code provides a detailed framework for classifying resources and reserves, with each category reflecting a different level of geological confidence and economic viability. Resources are categorized as Inferred, Indicated, or Measured based on the level of geological evidence and confidence, while reserves are categorized as Probable or Proven based on the viability of economic extraction.
  3. Public Reporting: The JORC Code sets out specific guidelines for how exploration results, mineral resources, and ore reserves should be reported to the public. The aim is to ensure that the reported information is not only accurate but also presented in a manner that can be readily understood by non-specialist investors and stakeholders.

Understanding these requirements is essential for anyone involved in the mining industry, as adherence to the JORC Code is not just good practice – it’s a legal requirement for companies listed on many of the world’s major stock exchanges.

Other Reporting Standards – NI 43-101, SAMREC

While the JORC Code is widely accepted and utilized globally, there are other key reporting standards used in different parts of the world that have their own specific requirements. Two such standards are the National Instrument 43-101 (NI 43-101) in Canada and the South African Code for the Reporting of Exploration Results, Mineral Resources and Mineral Reserves (SAMREC).

  1. National Instrument 43-101 (NI 43-101): Introduced by the Canadian Securities Administrators, the NI 43-101 sets the standards for all public disclosure of scientific and technical information concerning mineral projects within Canada. Similar to the JORC Code, it also necessitates the appointment of a ‘Qualified Person’ – akin to the Competent Person in JORC – to oversee and endorse disclosure documents. The NI 43-101 places great emphasis on the importance of safeguarding investors by providing accurate, comprehensive, and reliable information.
  2. South African Code for the Reporting of Exploration Results, Mineral Resources and Mineral Reserves (SAMREC): The SAMREC Code, used predominantly in South Africa, also strives to ensure transparency, materiality, and competence in the public reporting of exploration results, mineral resources, and mineral reserves. While the categories of classification mirror those of the JORC Code, the SAMREC code uniquely emphasizes the ‘modifying factors,’ which include mining, metallurgical, economic, marketing, legal, environmental, social, and governmental considerations, that should be taken into account when reporting resources and reserves.

Though these codes have regional origins, their influence extends globally due to the international nature of mining investment. While they are similar in many respects – aiming to ensure transparency and maintain investor confidence – differences arise primarily due to the legal and regulatory environments of their regions of origin. Understanding these various codes is paramount for mining professionals working in different jurisdictions and international investors alike.
