Introduction
Welcome to the Practice Guide to Auditing Mining Revenues and Financial Assurances for Site Remediation.
The purpose of this Practice Guide is to provide contemporary guidance for public sector auditors on how to plan, carry out, and report on performance audits of mining revenues and financial assurances for the remediation of mining sites. This Practice Guide is a companion document to our 2016 Practice Guide to Auditing Oil and Gas Revenues and Financial Assurances for Site Remediation.
Scope of the Practice Guide
This Practice Guide’s focus is strictly concerned with activities that are considered to be part of the upstream portion of the mining industry, including exploration, production and decommissioning activities. It focuses on private sector extraction activities on public lands.
The Practice Guide does not cover:
- revenues from downstream activities, which include refining, distributing, and selling mineral products;
- revenues from general taxes, such as income and sales taxes;
- small-scale and artisanal mining activities;
- the operations of state-owned mining corporations; or
- the spending of royalty revenues by governments.

The second part of the Guide also includes a short section on the Reporting Phase of the audit process. This section provides guidance on setting the context of the audit and on drafting recommendations. |
Finally, the Practice Guide includes a Glossary of important terms and a list of References for further reading on the mining sector.
Using the Practice Guide
The Practice Guide is a flexible tool that has been developed to be used within each audit office’s existing processes and procedures, in accordance with existing auditing and assurance standards. It is therefore a complement to current audit methodology.
Users of the Practice Guide do not have to read all its sections in order. Rather, the Guide has been designed to provide easy access to any section of interest and to allow readers to jump rapidly from one section to any other. Auditors are thus free to consult only the sections that best meet their needs.
