About the Minerals Reporting Australia (MRA)
Upholding Public Disclosure with Integrity
Minerals Reporting Australia Ltd (MRA) is a not-for-profit, member-led organisation working to improve the quality, integrity and transparency of public minerals disclosure in Australia.
MRA was established in response to concerns about the quality and consistency of public reporting of Exploration Results, Mineral Resources and Ore Reserves.
Today, our perspective extends across the minerals disclosure ecosystem, recognising that good disclosure depends not only on technical competence, but on the interaction between technical professionals, companies, boards, advisers, regulators, investors and the market.
Our purpose is to contribute constructively to better minerals disclosure and stronger market confidence.
Why It Matters
Public minerals disclosure informs investment decisions, company valuations and confidence in Australia's minerals sector.
An Exploration Result can influence market expectations. Mineral Resource and Ore Reserve estimates can underpin valuations, development decisions and corporate strategy. The quality of the disclosure therefore matters beyond technical compliance.
MRA provides a forum for examining the issues that influence good disclosure and for sharing experience and perspectives from across the minerals disclosure ecosystem.
We believe:
- Public minerals disclosure should be transparent, material and supported by reasonable grounds
- Competency is developed and demonstrated, not simply assumed
- Good disclosure depends on effective interaction between technical, corporate and governance responsibilities
- Peer engagement can strengthen professional judgement and practice
- Constructive engagement across the ecosystem can contribute to better disclosure and stronger market integrity
Who We Engage With
MRA engages with participants from across the minerals disclosure ecosystem, including:
- Competent Persons and other technical professionals
- Listed mining and exploration companies
- Directors, executives and company secretaries
- Investors and analysts
- Legal, governance and other professional advisers
- Regulators, exchanges and policymakers
- Professional and industry organisations
- Others with an interest in the quality and integrity of public minerals disclosure
Bringing these perspectives together helps build a better understanding of how technical information is developed, governed, communicated and used by the market.

More about MRA's GovernanceHow MRA Began
Minerals Reporting Australia grew from a peer-review initiative established in 2024 to examine the quality of public minerals reporting.
A small group of experienced professionals began meeting regularly to review public announcements and discuss the judgements, evidence and disclosure practices behind them. The process highlighted both recurring challenges and the value of constructive peer discussion.
Those conversations led to the establishment of Minerals Reporting Australia as an independent, not-for-profit, member-led organisation.
MRA has since broadened its focus beyond peer review, engaging across the minerals disclosure ecosystem on issues affecting competency, good practice, public disclosure and market confidence.
